- Chroman and tetrahydroquinoline ureas as potent TRPV1 antagonists
-
Novel chroman and tetrahydroquinoline ureas were synthesized and evaluated for their activity as TRPV1 antagonists. It was found that aryl substituents on the 7- or 8-position of both bicyclic scaffolds imparted the best in vitro potency at TRPV1. The most potent chroman ureas were assessed in chronic and acute pain models, and compounds with the ability to cross the blood-brain barrier were shown to be highly efficacious. The tetrahydroquinoline ureas were found to be potent CYP3A4 inhibitors, but replacement of bulky substituents at the nitrogen atom of the tetrahydroisoquinoline moiety with small groups such as methyl can minimize the inhibition.

- Structure-activity relationships of antimalarial indoloquinolines
-
Structure-activity relationships have been ascertained and chemical metodology developed for a series of antimalarial 3-chloroindoloquinoline-5-oxides.The basic side chain as well as the ring N-oxide are critical for antimalarial activity as is a bromine or chlorine in position 3.Substitution at positions 7,8,9,10 in not essential, although the most potent analog in our studies was the 8-nitro compound 4vv. indoloquinolines / antimalarial agents
