Lenacapavir: 2020 Small Molecule of the Year

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.

PF-07817883 (ibuzatrelvir) is an oral, second-generation SARS-CoV-2 M^pro inhibitor developed by Pfizer. These efforts follow the success of Pfizer's antiviral combination drug, Paxlovid, which was granted Emergency Use Authorization by the FDA for the treatment of COVID-19. PF-07817883 was granted Fast Track designation and recently completed a Ph. II clinical trial in outpatient adults with COVID-19 symptoms. This article details the discovery strategy for PF-07817883, which includes addressing metabolic soft spots identified through MetID studies, recent clinical developments, and more.

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. In this 4-part series we will give you an open-access overview of the M&A landscape, and then for Drug Hunter members in the coming weeks, we will be providing in-depth coverage and analysis of the small molecule-focused (parts 2 & 3) and biologics-based deals (part 4). This premium content includes background on the targets, chemical/biological matter and clinical data driving these deals.

We asked the global drug discovery community to nominate and vote on their favorite molecule from 2023, and the results are in. The 2023 winner, with the most votes between ten molecules, is Merck’s oral macrocyclic peptide inhibitor of PCSK9, MK-0616, derived from mRNA display technology and shown to have clinical efficacy. Herein, we highlight what makes MK-0616 so impressive to the drug discovery community.

The "New Drugs on the Horizon" sessions at the AACR Annual Meeting 2024 in San Diego revealed twelve innovative oncology agents and offered attendees a first look at their structures and preliminary data as they enter/progress in the clinic. In case you missed any of these exciting compounds – including selective CDK inhibitors, molecular glues, bifunctional degraders, a radiopharmaceutical, a bifunctional antibody, and an ADC – this article covers the structures and targets disclosed. A separate session disclosed the structure of a pan-RAS isoform inhibitor with remarkable clinical results.
