In the quest for novel PPARalpha/gamma co-agonists as putative drugs for the treatment of type 2 diabetes and dyslipidemia, we have used a structure-based design approach to identify propionic acids with a 1,5-disubstituted indole scaffold as potent PPARalpha/gamma activators. Compounds 13, 24, and 28 are examples of submicromolar dual agonists with different alpha/gamma EC50 ratios that are selective against the delta-isoform. Analysis of the X-ray complex structure of PPARgamma with the indole propionic acid 13 provides a rationalization for some of the observed SAR.
A novel class of tri-cyclic HIV integrase inhibitors were designed based on conformational analysis of 1,6-naphthyridine carboxamide compound L-870810 and docking the designed inhibitor into the active site of our integrase enzyme model. The efficient syntheses of pyrroloquinoline tri-cyclic analogs are described. The SAR studies resulted in the identification of a lead compound that is more potent and more soluble than L-870810.
This communication details both the syntheses and biological evaluation of a novel class of HIV-1 integrase inhibitors. When the quinoline moiety is replaced with the quinoxoline moiety, the antiviral activity is significantly compromised. Similarly, introduction of imidazole to replace the pyridine ring is deleterious to the potency of the compound against the enzyme. Substitution at the 3-position of the pyridine has been investigated. The presence of the pyridine ring in the tricyclic core is preferred for antiviral activity against HIV integrase.
