Abstract
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 greater 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 the 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 consequently, can be further harnessed for the treatment of neuropathic pain.
Keywords:
TRPV1 channels, neuropathic pain, natural products, semi-synthetic analogues, agonists, antagonists.
