摘要: A series of new 1-heteroaryl piperidinecarboxamide and piperazinylurea derivatives was synthesized evaluated as TRPV1 modulators in a Ca(2+) channel assay HEK-293 cells overexpressing the human recombinant channel. Structural variations putative key portions molecules afforded several compounds endowed with agonist and/or antagonist/desensitizing activity at low micromolar concentration. As promising examples from this series, piperidine-3-carboxamide derivative 31 exerts agonist/desensitizing concentration, while 39 41 act antagonists sub-micromolar potency.
