The Molecular Glue Degrader Landscape in 2022

Genentech’s GDC-6599 is the first oral TRP Ankyrin 1 (TRPA1) antagonist to reach Ph. IIa (NCT05660850) for chronic cough after preclinical studies and a Ph. I trial showed it was well-tolerated, in contrast to prior molecules. The transient receptor potential (TRP) family of ion channels has been the subject of intensive drug discovery efforts due to their critical role in the development and progression of pain, itch, and respiratory conditions.

PRMT5 is an epigenetic “synthetic lethality” target that has attracted much attention among drug hunters. The first generation of PRMT5 inhibitors was limited by systemic toxicities resulting in a cooling of industry interest, until the recent identification of tumor-specific inhibitors. These second-generation compounds target the MTA:PRMT5 complex in MTAP-deleted cancers—15% of all tumors—leading to a revival of the target. Read on to find out which companies are prevailing in the search for a first-in-class PRMT5 inhibitor and how their clinical compounds differentiate.

Drug Hunter has sifted through news articles, press releases, financial disclosures, SEC filings, and more to bring you a roundup of 2023’s biggest mergers and acquisitions (M&A) in the drug discovery world. Following our open-access industry overview, in part 2 of this 4-part series we bring you the small molecule-focused deals, ranked 11-20 by value. Covering a range of targets and modalities, this article gives Drug Hunter members in-depth background and analysis of the hottest science opening checkbooks in 2023.

DILI is a leading cause of acute liver failure, accounting for half of these cases and often resulting in drug withdrawals. Understanding and managing DILI risk as a medicinal chemist involves exploring the intricate interplay among properties and structural features. In this article, we provide a medicinal chemist's perspective on the current understanding of DILI mechanisms, highlight cutting-edge assay developments for a holistic assessment, and discuss strategies for predicting DILI risks.

Among the small molecule highlights in January’s news were a $100M+ Series A for a PARP1 + PI3Kα-focused company, clinical data with an SLC inhibitor for PKU, a 5-HT2C superagonist for seizures, and a NK1,3 dual antagonist for women’s health. A novel anti-obesity agent from phenotypic screening also made headlines, and the close of a major acquisition may bring relief to the industry. You can read about these notable scientific highlights and more below.
