Design, Synthesis, and Preliminary Pharmacological Evaluation of 4-Aminopiperidine Derivatives as N-Type Calcium Channel Blockers Active on Pain and Neuropathic Pain
Several compounds with a 4-aminopiperidine scaffold decorated on both nitrogen atoms by alkyl or acyl moieties containing the structural motifs of verapamil and of flunarizine, as well as those that are more frequent in known N-type calciumchannelantagonists, have been synthesized. Antinociceptive activity on the mouse hot-plate test was used to select molecules to be submitted to further studies
