seladelpar
In August 2024, seladelpar (LivdelziTM) became the first FDA-approved selective agonist of PPARδ (peroxisome proliferator-activated receptor δ), following an almost 20-year journey from the original discovery and patent publications. Originally developed by CymaBay in collaboration with Johnson & Johnson, approval was granted to Gilead Sciences following their February 2024 purchase of CymaBay Therapeutics for $4.3B. Seladelpar was approved as a second-line treatment for patients with primary biliary cholangitis.
AZD4144
Recently, a surge of (pre)clinical compounds inhibiting the NLRP3 inflammasome, often featuring a hexahydroindacene ring system, has emerged, including Nodthera’s ND-0796. In a push for new chemotypes, AZ and Mitsubishi Tanabe have disclosed their clinical compound, AZD4144, which is currently in Ph. I trials in healthy volunteers. The discovery story detailed their efforts to overcome PLD (phospholipidosis), genotoxicity, and hERG inhibition in a non-classical pharmacophore series. The discovery was presented by Anders Johansson at the EFMC-ISMC 2024 Meeting in Rome.
PF-07328948
Pfizer disclosed the structure and discovery of their oral small molecule BDK inhibitor/degrader, PF-07328948, during the ACS Fall 2024 First-Time Disclosures session in Denver. The team identified a thiophene carboxylic acid-based hit targeting an allosteric pocket on BDK. Through optimization, they overcame challenges such as potential IADRs and BDK-E2 complex stabilization. By manipulating the dihedral angle of the methoxy group, they enhanced binding interactions, verifying PF-07328948's unexpected mechanism of action in vivo. PF-07328948 is currently Ph. I trials.
SCO-267
SCO-267 is a full agonist of the GPCR GPR40, whose activation stimulates secretions of insulin and incretin. Since no crystal structures were available, the authors used conformational modeling to rationally improve the ligand from a weak lipophilic initial starting point (0.4 uM, clogP 9.4) to a more lipophilically efficient candidate (12 nM [...]
"compound 12j"
“compound 12j” is a potent agonist of the ghrelin hormone receptor, activation of which stimulates growth hormone secretion and appetite among other activities. Ghrelin receptor antagonists have previously been explored to treat disorders related to obesity such as diabetes, but an agonist could be useful in treating atrophic disorders like [...]
