Everything below concerns phase 2 trial. We keep the language plain, cite what the science says, and separate well-supported claims from open questions.
Last reviewed on 2025-09-24. Where a claim depends on a specific study, the study is described rather than over-claimed.
Human evidence remains limited to controlled studies. A phase 2 trial in adults with obesity reported large, dose-dependent reductions in body weight over 48 weeks, with gastrointestinal events as the most frequently recorded adverse effect. Phase 3 programs designated TRIUMPH, for obesity, and TRANSCEND, for type 2 diabetes, are intended to confirm efficacy and to characterize safety in larger populations. Related studies are examining conditions such as knee osteoarthritis in people with obesity and metabolic liver disease. Open questions include long-term tolerability, effects on lean mass, and what happens after treatment is stopped.
Retatrutide is an investigational synthetic peptide that acts on three receptor targets at once: glucose-dependent insulinotropic polypeptide, glucagon-like peptide-1, and glucagon. It is developed by Eli Lilly and appears in the literature and in trial registries under the code LY3437943. The molecule belongs to a class of engineered peptides designed to resist rapid breakdown and permit infrequent subcutaneous administration. No regulatory agency has approved it for clinical use, and all available human data come from controlled trials rather than from routine practice.
Several questions about the compound remain unresolved. The durability of weight reduction after treatment stops, the frequency of gastrointestinal side effects, and the long-term cardiovascular profile are topics of ongoing study. Regulatory submissions and phase 3 trial outcomes have not been fully reported in the public literature. Because most available data come from controlled trials rather than general-population use, conclusions about effectiveness outside study settings are provisional. The distinction between established findings and open questions matters when interpreting early coverage of the drug.
Retatrutide is an investigational peptide developed by a pharmaceutical company as a multi-receptor agonist for treating obesity and type 2 diabetes. The compound emerged from research into gut-hormone analogues that act on several receptors simultaneously rather than on a single target. Early preclinical work examined how combined activity at three distinct receptors might produce greater metabolic effects than single-receptor compounds. Published phase 2 results have described substantial reductions in body weight among participants, although the compound remains unapproved in most jurisdictions as of the mid-2020s.
Pharmacologically, retatrutide acts as a triple agonist at the glucagon-like peptide-1 receptor, the glucose-dependent insulinotropic polypeptide receptor, and the glucagon receptor. Activation of the first two receptors is associated with improved insulin secretion and reduced appetite. The glucagon receptor component is thought to increase energy expenditure, a mechanism that distinguishes this molecule from dual-agonist compounds. Researchers continue to investigate how the three activities interact and whether the combined profile offers advantages that justify additional clinical testing.
| Property | Value | Notes |
|---|---|---|
| Compound class | Synthetic triple-agonist peptide | Single linear chain carrying three receptor activities |
| Reported molecular weight | Approximately 4731 Da | Calculated from the published sequence; sources vary slightly |
| Appearance | White to off-white lyophilized powder | Typical of purified research-grade peptides |
| Solubility | Freely soluble in water; poorly soluble in nonpolar solvents | Dissolves in aqueous buffer near neutral pH |
| Storage of dry powder | -20 °C or below, desiccated, protected from light | Avoid repeated temperature cycling |
Mechanistic proposals link each receptor to a different physiological role. Activation of the glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 receptors is associated with reduced appetite, slower gastric emptying, and glucose-dependent insulin release. Glucagon receptor signaling, by contrast, is associated with increased energy expenditure and altered lipid handling, though it can also raise blood glucose. The design intent is to balance these contributions so that weight reduction is enhanced without unacceptable glycemic trade-offs. How well that balance holds across individuals is not fully resolved.
Published information places retatrutide in clinical development rather than on the market as an approved therapy. Early-stage and mid-stage trials have examined tolerability and changes in body weight, and larger studies continue to report results over time. Open questions include the durability of effects after treatment stops, the composition of weight lost, and cardiovascular outcomes over long periods. Statements about definitive benefit should therefore be treated as provisional. Regulatory status varies by jurisdiction and changes as applications are reviewed.
Retatrutide is an investigational synthetic peptide designed to activate three distinct receptor systems within a single molecule. Its pharmacological profile combines activity at the glucose-dependent insulinotropic polypeptide receptor, the glucagon-like peptide-1 receptor, and the glucagon receptor. This arrangement places it within a broader class of agents often described as multi-agonists, which contrast with compounds that engage one or two targets. Research interest centers on whether simultaneous signaling produces effects that single-receptor agonists cannot achieve alone. A single molecular entity also simplifies manufacturing and delivery logistics compared with combining separate agents.
多肽类化合物的表征通常依赖色谱与质谱联用技术。反相高效液相色谱用于评估纯度与有关物质，质谱用于确认分子量，肽图分析通过酶解碎片比对验证一级结构。这些手段组合使用，可以把目标产物与降解产物或类似物区分开来。单一方法往往不足以完成完整确认。
稳定性研究一般关注脱酰胺、氧化与聚集三类降解路径。脱酰胺多发生在天冬酰胺残基上，氧化常涉及甲硫氨酸与色氨酸，聚集则与浓度、温度以及容器界面接触有关。强制降解实验用于识别分子中较敏感的位点。这些结果会直接影响储存条件的设定与有效期的判断。
The peptide backbone is chemically modified to resist rapid enzymatic breakdown in the body. A fatty acid side chain promotes binding to serum albumin, which slows renal clearance and supports an extended circulation time. These modifications allow less frequent administration than would be possible with an unmodified peptide. The precise contribution of glucagon receptor activation to the overall metabolic effect remains an area of active investigation, because glucagon raises glucose while also increasing energy expenditure.
Development has progressed through early- and mid-stage human studies in adults with obesity and with type 2 diabetes. Published phase 2 data reported reductions in body weight and improvements in glycemic markers over the treatment period. No regulatory agency has approved the compound for any indication, and it remains available only within controlled research settings. Whether benefits observed in trials translate into durable outcomes after treatment stops is not yet established.
Additionally, in 2021, researchers demonstrated a 4.5 times increase in the current density breakdown limit of copper wire with an axially continuous graphene shell. The copper wire was coated by a continuous graphene sheet through chemical vapor deposition. The coated wire exhibited reduced oxidation of the wire during joule heating, increased heat dissipation (224% higher), and increased conductivity (41% higher).
=== Homology === GsMTx-4 shares less than 50% of its sequence homology with all other known peptide toxins. The highest percentage of sequence homology is shared with other tarantula toxins that block voltage-gated calcium channels and voltage-gated potassium channels. The ICK, as well as the residues F4, D13, and L20, are conserved in these tarantula toxins.
In radiology, various X-ray views use terminology based on where the X-ray beam enters and leaves the body, including the front to back view (anteroposterior), the back to front view (posteroanterior), and the side view (lateral).
== Flavors == Mint chocolate (or chocolate mint) is an individual flavor of chocolate, made by adding a mint flavoring, such as peppermint, spearmint, or crème de menthe, to chocolate. Mint chocolate can be found in a wide variety of confectionery items, such as candy, mints, cookies, mint chocolate chip ice cream, hot chocolate, and others. It is also marketed in a non-edible format in cosmetics with a distinctive mint fragrance. The chocolate component can be milk chocolate, regular dark chocolate, or white chocolate; due to this, mint chocolate has no one specific flavour, and so each chocolate-plus-flavor combination can be unique. The U.S. National Confectioners Association lists February 19 as "Chocolate Mint Day".
TAVR I - Special Army Volunteer Reserve or 'Ever Readies', echoing the earlier nickname for the TAER, bringing the Regular Army to war establishment and replacing casualties. These were to be given extra training and equipment and could now be called out by Queen's Order rather than Royal Proclamation in anticipation of war and TAVR II - forces called 'The Volunteers', for whom the old call-out arrangements continued. This category was split further split into TAVR IIA (Independent), e.g.: 51st Highland Volunteers and TAVR IIB (Sponsored), e.g.: Central Volunteer Headquarters, Royal Artillery. In addition were various miscellaneous units, such as OTCs and bands e.g. Northumbria Band of the Royal Regiment of Fusiliers. In the face of a considerable Parliamentary battle, and a public outcry led by the County Associations, the government agreed to retain an additional 28,000 men in 87 'lightly armed' infantry units and a few signals units in a category called TAVR III, designed for home defence, but, months later in January 1968, these were all earmarked to be disbanded, with 90 becoming eight-man "cadres". In November that year, the call-out arrangements for TAVR II units were brought in line with TAVR I.

The serine has an -OH group that is able to act as a nucleophile, attacking the carbonyl carbon of the scissile peptide bond of the substrate. A pair of electrons on the histidine nitrogen has the ability to accept the hydrogen from the serine -OH group, thus coordinating the attack of the peptide bond. The carboxyl group on the aspartic acid in turn hydrogen bonds with the histidine, making the nitrogen atom mentioned above much more electronegative. The whole reaction can be summarized as follows:
Paxillosida (7 families, 48 genera, 372 species) This is a primitive order whose members do not extrude their stomach when feeding and both anus and tube feet suckers are absent. Papulae are present on their aboral surface, and they possess marginal plates and paxillae. They mostly inhabit soft substrates. There is no brachiolaria stage in their larval development. The comb starfish (Astropecten polyacanthus) is a member of this order. Spinulosida (1 family, 8 genera, 121 species) Most species in this order lack pedicellariae; all have a delicate skeletal arrangement with small or no marginal plates on the disc or arms. They have numerous groups of short spines on the aboral surface.
The (1,2) and (3,4) bonds can also be formed from N-substituted α-aminoketones and formamide with heat. The product will be a 1,4-disubstituted imidazole, but here since R1 = R2 = hydrogen, imidazole itself is the product. The yield of this reaction is moderate, but it seems to be the most effective method of making the 1,4 substitution.

== Disease management == Crown gall disease caused by Agrobacterium tumefaciens can be controlled by using various methods. The best way to control this disease is to take preventative measures, such as sterilizing pruning tools so as to avoid infecting new plants. Performing mandatory inspections of nursery stock and rejecting infected plants as well as not planting susceptible plants in infected fields are also valuable practices. Avoiding wounding the crowns/roots of the plants during cultivation is important for preventing disease. In horticultural techniques in which multiple plants are joined to grow as one, such as budding and grafting these techniques lead to plant wounds. Wounds are the primary location of bacterial entry into the host plant. Therefore, it is advisable to perform these techniques during times of the year when Agrobacteria are not active. Control of root-chewing insects is also helpful to reduce levels of infection, since these insects cause wounds (a.k.a. bacterial entryways) in the plant roots. It is recommended that infected plant material be burned rather than placed in a compost pile due to the bacteria's ability to live in the soil for many years. Biological control methods are also utilized in managing this disease. During the 1970s and 1980s, a common practice for treating germinated seeds, seedlings, and rootstock was to soak them in a suspension of K84. K84 is a strain of Rhizobium rhizogenes (formerly classified under A. radiobacter, but later reclassified) which is a species related to A. tumefaciens but is not pathogenic.
need not be constant – in general, they depend on two thermodynamics variables if the fluid contains a single chemical species, say for example, pressure and temperature. Any equation that makes explicit one of these transport coefficient in the conservation variables is called an equation of state. The most general of the Navier–Stokes equations become
The most common dashi stocks for miso soup are made of niboshi (dried baby sardines), kombu (dried kelp), katsuobushi (thin shavings of fermented, dried, and smoked bonito), or hoshi-shiitake (dried shiitake). The kombu can also be used with katsuobushi or hoshi-shiitake. Kelp or shiitake dashi give a vegetarian soup stock. When the soup includes clams such as asari, shijimi, or hamaguri, prepared dashi is often not used. Outside Japan, American- or European-style miso soup is sometimes made by dissolving miso in a Western vegetable stock. It can also be made with chicken broth. The stock might include ingredients such as negi, carrot, potato and daikon radish. In some versions of the dish, chicken stock, Western-style fish stock, and other non-dashi bases can even be used, but there is some debate over whether or not miso soups made using these non-traditional bases count as true miso soup.
The internal dynamics of protons are complicated, because they are determined by the quarks' exchanging gluons, and interacting with various vacuum condensates. Lattice QCD provides a way of calculating the mass of a proton directly from the theory to any accuracy, in principle. The most recent calculations claim that the mass is determined to better than 4% accuracy, even to 1% accuracy (see Figure S5 in Dürr et al.). These claims are still controversial, because the calculations cannot yet be done with quarks as light as they are in the real world. This means that the predictions are found by a process of extrapolation, which can introduce systematic errors. It is hard to tell whether these errors are controlled properly, because the quantities that are compared to experiment are the masses of the hadrons, which are known in advance. These recent calculations are performed by massive supercomputers, and, as noted by Boffi and Pasquini: "a detailed description of the nucleon structure is still missing because ... long-distance behavior requires a nonperturbative and/or numerical treatment ..." More conceptual approaches to the structure of protons are: the topological soliton approach originally due to Tony Skyrme and the more accurate AdS/QCD approach that extends it to include a string theory of gluons, various QCD-inspired models like the bag model and the constituent quark model, which were popular in the 1980s, and the SVZ sum rules, which allow for rough approximate mass calculations.
Hong Kong generates most of its electricity locally. The vast majority of this energy comes from fossil fuels, with 46% from coal and 47% from petroleum. The rest is from other imports, including nuclear energy generated in mainland China. Renewable sources account for a negligible amount of energy generated for the territory. Small-scale wind-power sources have been developed, and a small number of private homes and public buildings have installed solar panels. With few natural lakes and rivers, high population density, inaccessible groundwater sources, and extremely seasonal rainfall, the territory lacks a reliable freshwater supply. The Dong River in Guangdong supplies 70% of the city's water, with the remaining demand met by harvesting rainwater locally. Toilets in most built-up areas of the territory flush with seawater, which reduces freshwater use. Broadband Internet access is widely available, with 99.3% of households connected. Connections over fibre-optic infrastructure are increasingly prevalent, contributing to the high regional average connection speed of 21.9 Mbit/s (the world's fourth-fastest). Mobile-phone use is ubiquitous; there are almost 22 million mobile-phone accounts registered in Hong Kong, which is almost triple the territory's population.

It is an investigational peptide that activates three hormone receptors: GIP, GLP-1 and glucagon. It is being studied mainly for obesity and type 2 diabetes, and it is not approved for any clinical use. Published information comes from controlled trials rather than from general practice.
No. As of the most recent public information it remains investigational in every jurisdiction. Material sold under this name outside trials is a research chemical, not an approved medicine. Current status should always be checked against regulator notices.
Dual agonists act on two receptors, usually GIP and GLP-1. Retatrutide adds glucagon receptor activity, which is associated with increased energy expenditure. Whether that third component adds clinically meaningful benefit over dual agonism remains an open question.
It is designed as a triple agonist acting on the GLP-1, GIP, and glucagon receptors. This combination is intended to influence appetite, insulin secretion, and energy expenditure. Single-receptor and dual-receptor compounds act on a narrower set of targets.
