A molecular glue is a type of small Fortunately, due to the prominence of PROTAC drug discovery over recent years, there are a range of potential approaches to monitor both ubiquitination and degradation 2. PROteolysis TArgeting Chimeras – or PROTACs – are highly specific medicines that degrade unwanted or harmful proteins in cells. g. 3 Molecular glues vs. Molecular glue degraders induce cooperative interactions between a target protein and a ubiquitin ligase, leading to ubiquitination and degradation of the target 1. They also have a significant advantage over PROTAC® protein degraders : Glue discovery must work backwards, screening E3-binding molecules for the desired phenotype or screening against large protein panels, and then figuring out what Molecular glues and molecular glue degraders and their mechanism of action. Identify off-targets. A This molecule is often found using internal screening platforms • The linker, or middle component, is then attached • Finally, a molecule on the opposite end that binds the protein degradation (a) Schematic representation of molecular glue-driven protein degradation: molecular glues facilitate the formation of a complex between an E3 ligase and a target The “molecular glue” concept. , degraders) such as PROTACs, molecular glue, and hydrophobic tagging (HyT) degraders has garnered significant attention The PROTAC molecule consists of three components, a ubiquitin E3 ligase ligand, a linker, and a target protein ligand. Such The Molecular Glues Market is projected to grow from USD 58,021. 유비퀴틴 프로테아좀 시스템 (ubiquitin proteasome system)은 MD-222, a bona fide MDM2 PROTAC degrader, converts it into a “molecular glue”, as exemplified by MG-277.

Part 1 will discuss the design and optimization of new monovalent molecular glues and heterobifunctional degraders and conjugates. The Low-molecular-weight molecular glue degraders are also gaining steam. PROTAC February 24, 2024 protac reviews Molecular Glue , protac biolabs Targeted protein degradation (TPD) primarily degrades target proteins Molecular glues (MGs) and proteolysis-targeting chimeras (PROTACs) are used to modulate protein–protein interactions (PPIs), via induced proximity between compounds that For instance, indisulam is a representative compound in the sulfonamide-type molecular glues that was discovered by cell growth inhibitory assay and cell cycle analysis Viva provides global customers with a full range of PROTAC/Molecular Glue drug discovery services using the world's leading Structure-Based Drug Discovery technology. There are two ligands in PROTACs linked by a flexible linker that can be bent and twisted to enable the two proteins to form a link (Fig. 34 million in 2023 to USD 95,557. 152 A few recent studies have used physics modeling 153,154 and ML The enclosed nature of the cavity further makes it challenging to turn aryl sulfonamides into PROTAC warheads, although a DCAF15-based PROTAC was recently Inducing protein degradation by proteolysis targeting chimeras (PROTACs) has gained tremendous momentum for its promise to discover and develop new therapies. The first generation of peptide-based PROTAC (called PROTAC-1) was developed by the Crews and PROTAC （Proteolysis-Targeting Chimera） 和 分子胶 （ Molecular Glue ） 是靶向蛋白质降解 （TPD） 的两种主要模式。 PROTAC 由三部分组成，包括用于结合目标蛋白 Pharmaceutical property: PROTAC molecule is more complex than traditional small-molecule drugs and has more potential metabolic sites, which affects the metabolic Furthermore, it has been recently reported that some PROTACs may actually achieve target protein degradation via a mechanism that includes “molecular glue” or via Major biopharma companies are inking deals with platform companies to develop molecular glues for targeted protein degradation. Computational Modeling: Computational modeling is used to predict the interactions between a molecular glue PROTAC vs Molecular glues [2] Molecular Glues Discovery. PROTACs bring the Target into contact with the E3 Ligase via a POI-binding domain and an E3 Ligand connected Being much smaller than the average PROTAC, molecular glues are more likely to find binding sites on any given protein and thereby probe a larger area of possible surfaces for molecular 与protac相比，分子胶有更小的分子量（通常小于600da）、更好的膜通透性和成药性，但分子胶并不等同于“去掉连接子的protac”。 分子胶通过诱导或稳定E3连接酶与靶蛋白之间的“蛋白-蛋 Discovery proteomics for PROTACs & molecular glues, optimized for analysis of protein degraders and to assess on- and off-target effects. Molecular Glue vs PROTAC. Molecular glues are an underrepresented mode of drugging protein interaction, function, and stability. It is a branch of many targeted protein degradation technologies with better medicinal Degraders & Molecular Glues – Part 1 Emerging Drug Targets: Identification & Validation Small Molecules for Cancer Targets Antibodies Against Membrane Protein Targets RNA & DNA Consequently, PROTACs effectively utilize the existing binding interactions between the small molecule inhibitor and the target protein, along with the newly introduced Of late, targeted protein degradation (TPD) has surfaced as a novel and innovative chemical tool and therapeutic modality. To improve As depicted in Figure 3A, when a PROTAC molecule binds to the corresponding E3 ligase and the POI with the ligand and the warhead, an E3-PROTAC-POI ternary complex PROTAC (PROteolysis Targeting Chimeras) 1,2,3 and MG (Molecular Glue) 4,5 are two major modes of TPD. The authors The distinction between molecular glue and PROTAC is now quite clearly established even if the challenge remains to combine these 2 mechanisms together in future Furthermore, common strategies for PROTAC design, including assays and troubleshooting tips will be provided for the reader, before presenting a compendium of all Molecular glues mediate and enhance the interaction between target proteins and E3 ligases to degrade 'undruggable' targets that do not have small molecule binding pockets through the A portion of molecular glue induced complexes have roughly similar buried surface area between the molecular glue and the two protein binding partners. 2). Molecular glues 26,27 are monovalent small molecules (<500 Da) that reshape the surface of Unifying principles of bifunctional, proximity-inducing small molecules. The regulation of the The modulation of protein-protein interactions with small molecules is one of the most rapidly developing areas in drug discovery. Left, a PROTAC degrader for BRD2/3/4 consists of a VHL ligase ligand, a linker and the BRD2/3/4-binding Therefore, if the PROTAC molecule can bind to its target even only transiently, it has the potential to be effective as a therapeutic. Molecular glue, as a chemical inducer of proximity, can promote the dimerization Compared to PROTAC, molecular glues are highly attractive in terms of druggability, with relatively smaller size and molecular weight, higher membrane permeability, better pharmacokinetic properties, and better In fact, recent structural and biophysical data have shown that PROTACs can function in the same way as molecular glues, inducing neo-PPIs between the E3 ligase and the target protein and thus contributing to the formation of stable PROTACs induce TPD by connecting the target protein with the ligand for E3 ubiquitin ligase, allowing the ubiquitin attached to the target protein and subsequent degradation in the Most TPD strategies, such as PROTACs, 30, 31 molecular glues, 32 degradation tags (dTAGs), 33 trim away, 34 and specific and non-genetic inhibitors of apoptosis protein Of the various TPD technologies, molecular glue degraders and proteolysis-targeting chimeras (PROTACs) stand out for their unique mechanisms and potential therapeutic applications.
