Natural Products and some semi-synthetic analogues as potential TRPV1 Ligands for attenuating Neuropathic pain
Natural products and leads inspired by them have acted as a probe for successful drug discovery for many decades. Pain is an obnoxious sensory and emotional experience associated with potential tissue damage. It affects the quality of life of patients to a great extent. Despite the availability of several agents targeting TRP receptors, none of them can proficiently alleviate neuropathic pain. TRPV1 is a prospective target for treating neuropathic pain as it is recognized to modulate the pain circuitry at the periphery and central level. In this review, we have discussed several natural molecules (such as Capsaicinoids, capsinoids, Piperine, Eugenol, Scutigeral, Ginsenosides, Cinnamaldehyde, Camphor, Shogaol, Gingerols, Zingerone, Allicin, Evodiamine, Allylisothiocyanate, Cannabidiol, Ricinoleic acid, Isovelleral, Capsazepine, Thapsigargin, Pellitorine, Yohimbine, Curcumin) and some semi-synthetic analogues that activate TRPV1 channels, and can be further harnessed consequently for the treatment of neuropathic pain.
