  8-chloro-4-oxo-N-[4-(trifluoromethoxy)phenyl]-3,4-dihydrospiro[chromene-2,4'-piperidine]-1'-carboxamide 在 4-二甲氨基吡啶 、 sodium tetrahydroborate 、 盐酸-N-乙基-Nˊ-(3-二甲氨基丙基)碳二亚胺 作用下， 以 乙醇 、 二氯甲烷 为溶剂， 反应 19.0h， 生成 (4R)-8-chloro-1'-{[4-(trifluoromethoxy)phenyl]carbamoyl}-3,4-dihydrospiro[chromene-2,4'-piperidine]-4-yl N-[(benzyloxy)carbonyl]-L-tryptophanate

  Synthesis and pharmacological evaluation of novel N-aryl-3,4-dihydro-1′H-spiro[chromene-2,4′-piperidine]-1′-carboxamides as TRPM8 antagonists

  摘要：

  A novel series of N-aryl-3,4-dihydro-1'H-spiro[chromene-2,4'-piperidine]-1'-carboxamides was identified as transient receptor potential melastatin 8 (TRPM8) channel blockers through analogue-based rational design, synthesis and screening. Details of the synthesis, effect of aryl groups and their substituents on in-vitro potency were studied. The effects of selected functional groups on the 4-position of the chromene ring were also studied, which showed interesting results. The 4-hydroxy derivatives showed excellent potency and selectivity. Optical resolution and screening of alcohols revealed that (R)-(-)-isomers were in general more potent than the corresponding (S)-(+)-isomers. The isomer (R)-(-)-10e (IC50: 8.9 nM) showed a good pharmacokinetic profile upon oral dosing at 10 mg/kg in Sprague-Dawley (SD) rats. The compound (R)-(-)-10e also showed excellent efficacy in relevant rodent models of neuropathic pain. (C) 2013 Elsevier Ltd. All rights reserved.
