KRAS Roundup: Twelve G12C Clinical Molecules to Know

This article highlights million-dollar molecules that were recently in the news with related patent applications that give clues to their structures and properties. This edition includes Maze’s glycogen synthase 1 (GYS1) inhibitors that were recently licensed to Sanofi, allosteric androgen receptor (AR) modulators that may be of interest to targeted protein degradation researchers, brain-penetrant HER2 and ROCK2 inhibitors, and MDM2 degraders.

The 2024 SABCS brought together over 10,000 attendees from more than 100 countries, including leading academics, researchers, patient advocates, and healthcare professionals, to showcase state-of-the-art advances in breast cancer research. In our highlights, we will cover exciting clinical trial updates from this year’s symposium, including targeted molecules addressing key pathways such as CDK4, CDK2, and PI3Kα, along with advancements in next-generation oral SERDs (selective estrogen receptor degraders).

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.

There has been substantial interest in the development of screening methods capable of surveying a wider sample of chemical space and larger numbers of compounds. Over the past two decades, DEL technology has evolved into a broadly utilized and validated platform in drug discovery, yielding diverse hits for a wide range of biologically relevant targets. Read the full review for a historical and technical overview of DEL technology, including how libraries are prepared and screened, a comparison to other HTS methods, and examples of successful applications in drug discovery.

The discovery that individuals with null mutations in the NaV1.7 exhibited pain insensitivity sparked interest in targeting NaV1.7 to potentially treat pain. Despite the potential of selectively inhibiting sodium channels like NaV1.7, NaV1.8, and NaV1.9 for pain management, developing selective inhibitors suitable for clinical use has proven challenging. This article complements our coverage of VX-548, NaV1.8 as a critical target in pain management, and our NaV1.8 compound roundup and provides a reminder of noteworthy preclinical and clinical NaV1.7 small molecule inhibitors as of April 2024.
