KLS-13019 is a CBD (cannabidiol) analogue and GPR55 (G protein-coupled receptor 55) antagonist from Kannalife Sciences, which shows promise as a novel therapeutic for neuropathic pain, particularly chemotherapy-induced neuropathic pain.

Compound 20 is a galactose-based monosaccharide Gal-3 inhibitor from Bristol Myers Squibb that shows potential in targeting fibrotic diseases.

AstraZeneca recently disclosed the structure and discovery journey of their oral small molecule PCSK9 inhibitor, AZD0780, during the ACS Fall 2024 First Time Disclosures session in Denver. Discover how the team identified a fragment hit targeting a previously unexplored pocket, verified its novel mechanism of action, and successfully advanced it into a clinical compound now in Ph. II trials for patients with dyslipidemia.

BridgeBio’s acoramidis (Attruby), an oral, second-generation stabilizer of the TTR protein, has been approved by the FDA for the treatment of ATTR-CM (transthyretin amyloid cardiomyopathy). Amyloid deposits in the heart muscle characterize the rare but potentially fatal disease. This case study reviews the history of TTR modulation, early experiments validating the therapeutic potential of TTR stabilization, the binding mechanism of acoramidis to TTR, the importance of binding enthalpy for differentiation, and the molecule’s impressive 30-month clinical data following an early scare.

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.
