Anti-inflammatory and analgesic potential of OA-DHZ; a novel semisynthetic derivative of dehydrozingerone

Despite various advances in the arena of the current system of medicine, there are numerous side effects associated with the therapeutics which essentially demand research on the development of safer therapeutics. One way is to explore the bioactive plant secondary metabolites and their semisynthetic derivatives. In context to this, we analyzed OA-DHZ, a dehydrozingerone derivative as the later has been reported to show anti-inflammatory and analgesic properties. OA-DHZ was found to be having promising anti-inflammatory and analgesic potential. OA-DHZ was found to inhibit the carrageenan-induced edema and leukocyte migration, acetic acid-induced increase in vascular permeability and lipopolysaccharide-induced pro-inflammatory cytokines like TNF-alpha, IL-6, and IL-1 beta. Meanwhile, it was also found to potentially inhibit thermally as well as chemically induced pain signifying its analgesic/nociceptive potential. Further, safety pharmacology studies using in vivo animal models for the central nervous system, gastrointestinal tract, the cardio-respiratory system suggest that optimum functioning of vital organ systems does not get altered after single oral administration. Also, the acute toxicity study revealed its nontoxic nature up to 2000 mg/kg. This study paves the way for future exploration and development of OA-DHZ based on its potent activity and nontoxic nature.
