4-(Phenylsulfonyl)piperidines: Novel, Selective, and Bioavailable 5-HT2A Receptor Antagonists
摘要:
On the basis of a spirocyclic ether screening lead, a series of acyclic sulfones have been identifed as high-affinity, selective 5-HT2A receptor antagonists. Bioavailability lacking in the parent, 1-(2-(2,4-difluorophenyl)ethyl)-4-(phenylsulfonyl)piperidine (12), was introduced by using stability toward rat liver microsomes as a predictor of bioavailability. By this means, the 4-cyano- and 4-carboxamidophenylsulfonyl derivatives 26 and 31 were identified as orally bioavailable, brain-penetrant analogues suitable for evaluation in animal models. Bioavailability was also attainable by N substitution leading to the N-phenacyl derivative 35. IKr activity detected through counterscreening was reduced to insignificant levels in vivo with the latter compound.

each represent a substituent; n represents 0 or an integer of 1 to 3; m represents 0 or an integer of 1 to 6; and p represents an integer of 1 to 3. The compounds have serotonin antagonism. They are therefore clinically useful as medicaments, in particular, for treating, ameliorating, and preventing spastic paralysis. They are also useful as central muscle relaxants for ameliorating myotonia.

potential ocular hypotensiveagents, we studied compounds that act on two receptors (serotonin 2A and adrenergic α1) linked to the regulation of aqueous humour dynamics. Herein we describe the design, synthesis, and pharmacological profiling of a series of novel bicyclic and tricyclic N2‐alkyl‐indazole‐amide derivatives. This study identified a 3,4‐dihydropyrazino[1,2‐b]indazol‐1(2H)‐one derivative with potent
