In vitro and in vivo profile of 5-[(4'-trifluoromethyl-biphenyl-2-carbonyl)-amino]-1H-indole-2-carboxylic acid benzylmethyl carbamoylamide (dirlotapide), a novel potent MTP inhibitor for obesity.

The synthesis of a novel gut selective MTP inhibitor, 5-[(4'-trifluoromethyl-biphenyl-2-carbonyl)-amino]-1H-indole-2-carboxylic acid benzylmethyl carbamoylamide (dirlotapide), and its in vitro and in vivo profile are described. Dirlotapide (3) demonstrated excellent potency against MTP enzyme in HepG2 cells and canine hepatocytes. This novel MTP inhibitor also showed excellent efficacy when tested in a canine food intake model.

Synthesis and SAR of azalide 3,6-ketal aromatic derivatives as potent Gram-positive and Gram-negative antibacterial agents.

3,6-Ketals of 15-membered azalide pseudoaglycones are a novel series of macrolide antibiotics. The aromatic derivatives of the azalide 3,6-ketals demonstrated potent antibacterial activities against both Gram-positive and Gram-negative bacteria.
