A Prodrug Bioactivated in the Eye for Ocular Hypertension: Omidenepag

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.

Several multi-million dollar acquisitions or license agreements took place in November 2023 for hot drug targets, with assets from selective PARP1 inhibitors to GLP1R agonists, and others. This recent news roundup highlights the notable acquisitions by pharma companies for rights to molecules in a range of different indications, with illustrative patent examples for undisclosed structures.

PI3 kinases are part of the PI3K/Akt/mTOR signaling pathway that is downstream of Receptor Tyrosine Kinases (RTKs), G-protein-coupled receptors (GPCR), and GTPases such as KRAS. Since their identification in the 1980s, and due to their central role in cancer, the therapeutic targeting of the phosphatidylinositol-3-kinase (PI3K), and more [...]

There were 16 acquisitions of companies with small molecule drug assets in 2021 and one merger. Here is a more in-depth look into all of the lead small molecules acquired in 2021, including a review of: The lead molecules in each acquisition and their structural representations where disclosed The mechanism of action, stage, and indication of [...]

together with Dr. Jennifer Huen, Saumil Patel, and Dr. Naveed Yasin In 2021, the FDA approved 9 non-radiological novel small molecule drugs for oncology. Excluding melphalan flufenamide, which has already been withdrawn, the remaining FDA-approved novel small molecule oncology drugs of 2021 are: umbralisib (PI3Kδ and CK1ε inhibitor) sotorasib [...]
