Novel Transient Receptor Potential Vanilloid 1 Receptor Antagonists for the Treatment of Pain: Structure−Activity Relationships for Ureas with Quinoline, Isoquinoline, Quinazoline, Phthalazine, Quinoxaline, and Cinnoline Moieties
摘要:
Novel transient receptor potential vanilloid 1 (TRPV1) receptor antagonists with various bicyclic heteroaromatic pharmacophores were synthesized, and their in vitro activity in blocking capsaicin activation of TRPV1 was assessed. On the basis of the contribution of these pharmacophores to the in vitro potency, they were ranked in the order of 5-isoquinoline > 8-quinoline = 8-quinazoline > 8-isoquinoline greater than or equal to cinnoline approximate to phthalazine approximate to quinoxaline approximate to 5-quinoline. The 5-isoquinoline-containing compound 14a (hTRPV1 IC50 = 4 nM) exhibited 46% oral bioavailability and in vivo activity in animal models of visceral and inflammatory pain. Pharmacokinetic and pharmacological properties of 14a are substantial improvements over the profile of the high-throughput screening hit 1 (hTRPV1 IC50 = 22 nM), which was not efficacious in animal pain models and was not orally bioavailable.

spectrum of oxidized products corresponded to the one got in the photoreactions of azaarenes with hydrogen peroxide. The formation of several oxidation and nitration products of the pyridine ring with its low electron density was explained by the reaction of excited states of azaarenes. The photoreactions with nitrite ions only led to the formation of oxidized and nitrated products. Nitroso products were not

1H-indole (2), a series of related arylpiperazin-4-yl-cyclohexyl indole analogs were synthesized then evaluated as 5-HT transporter inhibitors and 5-HT(1A) receptor antagonists. The investigation of the structure-activity relationships revealed the optimal pharmacophoric elements required for activities in this series. The best example from this study, 5-(piperazin-1-yl)quinoline analog (trans-20)
