Symposium

[S07] Drug development based on PPAR-ligand structural studies

Sat. Mar 26, 2022 9:30 AM - 11:30 AM [Room R] Shirotori Hall (South) (Bldg. 4: 1F)

Organizer: Isao Ishii (Showa Pharm. Univ.)

Peroxisome proliferator-activated receptor (PPAR) is the nuclear receptor-type transcription factor with three cognate subtypes (α, δ, γ) that drastically regulates lipid, glucose and amino acid metabolism. Fibrate-class PPARα agonists are clinically used as lipid (triglyceride)-lowering drugs while thiazolidinedione-class PPARγ agonists as anti-diabetic drugs; PPARδ agonists are expected to be anti-metabolic syndrome drugs that have properties mimicking those of both PPARα and PPARγ agonists. Furthermore, PPAR dual or pan agonists that binds to 2 or 3 PPAR subtypes are currently in worldwide clinical trials that mainly target NASH/NAFLD. PPARs have relatively large ligand binding pockets compared to other nuclear receptors, and accept a wide variety of ligands with various fashions and regulate transcription of multiple gene sets. However, non-transcription regulation-type effects are also reported, which attract further attention as another pharmacological impact. This symposium features five speakers who present PPAR–various ligand structures mainly revealed by X-ray crystallography and drug development based on such information.
