- New ursolic acid derivatives bearing 1,2,3-triazole moieties: design, synthesis and anti-inflammatory activity in vitro and in vivo
-
Abstract: In order to discover novel anti-inflammatory agents, three series of compounds obtained by appending 1,2,3-triazole moieties on ursolic acid were designed and synthesized. All compounds have been screened for their anti-inflammatory activity by using an ear edema model. The potent anti-inflammatory compound was subjected to in vitro cyclooxygenase COX-1/COX-2 inhibition assays. In general, the derivatives were found to be potent anti-inflammatory activity. Especially, the compound 11b exhibited the strongest activity of all of the compounds prepared, with 82.81% inhibition after intraperitoneal administration, which was better than celecoxib as a positive control. Molecular docking results unclose the rationale for the interaction of the compound 11b with COX-2 enzyme. Further studies revealed that compound 11b exhibited effective COX-2 inhibitory activity, with half-maximal inhibitor concentration (IC50) value of 1.16?μM and selectivity index (SI = 64.66) value close to that of celecoxib (IC50 = 0.93?μM, SI = 65.47). Taken together, these results could suggest a promising chemotype for development of new COX-2-targeting anti-inflammatory agent. Graphic abstract: [Figure not available: see fulltext.]

- 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.
