5TTO - PubMed Abstract: 
Peroxisome proliferator-activated receptor ¦Ã (PPAR¦Ã) is a nuclear receptor central to fatty acid and glucose homeostasis. PPAR¦Ã is the molecular target for type 2 diabetes mellitus (T2DM) therapeutics TZDs (thiazolidinediones), full agonists of PPAR¦Ã with robust antidiabetic properties, which are confounded with significant side effects. Partial agonists of PPAR¦Ã, such as INT131 (1), have displayed similar insulin-sensitizing efficacy as TZDs, but lack many side effects. To probe the structure-activity relationship (SAR) of the scaffold 1, we synthesized 14 analogs of compound 1 which revealed compounds with higher transcriptional potency for PPAR¦Ã and identification of moieties of the scaffold 1 key to high transcriptional potency. The sulfonamide linker is critical to activity, substitutions at position 4 of the benzene ring A were associated with higher transcriptional activity, substitutions at position 2 aided in tighter packing and activity, and the ring type and size of ring A affected the degree of activity.
