Orforglipron is an oral non-peptide glucagon-like peptide-1 (GLP-1) receptor partial agonist that entered Ph. III for obesity and type-2-diabetes mellitus (T2DM). This 2020 and 2023 Molecule of the Year nominee (nominated initially back when it was still in Ph. I) was first discovered by Chugai Pharmaceuticals under the name OWL833, then licensed by Eli Lilly for worldwide development under the name LY3502970. The article discusses where it sits in the GLP-1R agonist landscape, why it’s scientifically notable, how it works with illustrations from cryo-EM structures, its synthesis, and more.

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.

Merck’s macrocyclic PCSK9 protein-protein interaction (PPI) inhibitor, MK-0616, is a once-daily PCSK9-lowering and LDL-cholesterol-lowering small molecule that has recently demonstrated antibody-like efficacy as an oral agent in the clinic. The program highlights numerous technical achievements at the forefront of modern drug discovery, and will set a standard for modern “classics in drug discovery” for some time.

GS-9688 (selgantolimod) is a potent and selective TLR8 agonist sparing related receptor TLR7, and is intended to induce better immune responses in chronic hepatitis B. Since systemic activation of TLR8 was undesirable, selgantolimod was designed to have high first-pass hepatic clearance to induce effective antiviral immunity in the liver but [...]

Dorzagliatin (Hua Medicine) is an oral dual-acting full glucokinase (GK) activator being developed for type 2 diabetes . More than 50 years since the first report of the role of GK in glucose metabolism, no agents targeting this enzyme have been approved, although not for lack of trying. We recently covered a partial GK activator [...]
