    Efficacy of p-coumaric acid in chronic constriction injury induced neuropathic pain in rats
    (Indian Drug Manufacturers' Association, 2021-12-14T00:00:00) Bharti, Akash; Kaur, Jaspreet; Kumar, Amit; Singh, Simranjit; Kumar, Deepak
    The present research work has been designed to evaluate the effect of p-coumaric acid in chronic constriction injury (CCI) of sciatic nerve induced neuropathic pain in rats. In addition, biochemical tests such as thiobarbituric acid reactive substances (TBARS), reduced glutathione (GSH) and total protein were performed in sciatic nerve tissue sample. The neuropathic pain has been effi ciently and successfully induced in rat by the performance of CCI. The battery of behavioural test showed the development of neuropathic pain as an index of rising the paw and tail thermal and mechanical pain sensitivity. The treatment of p-coumaric acid at dose 50 and 100 mg kg-1, p.o. for 15 consecutive days have been shown to produce signifi cant ameliorative effect on CCI of sciatic nerve induced neuropathic pain sensitivity. In addition, CCI of sciatic nerve also induces the oxidative stress in nervous system by rising TBARS, decrease GSH and proteins levels in sciatic nerve tissue and these effects are reversed via administration of p-coumaric acid and statistically equivalent to standard drug. Hence, it may be concluded that, p-coumaric acid can be useful in the management of neuropathic pain symptoms. � 2021 Indian Drug Manufacturers' Association. All rights reserved.

    Engagement of phytoestrogens in breast cancer suppression: Structural classification and mechanistic approach
    (Elsevier Masson s.r.l., 2020-11-24T00:00:00) Tanwar, Ankur Kumar; Dhiman, Neha; Kumar, Amit; Jaitak, Vikas
    Cancer is the world's devastating disease, and breast cancer is the most common reason for the death of women worldwide. Many synthetic drugs and medications are provided with their beneficial actions, but all of these have side effects and resistance problems. Natural remedies are coming forward to overcome the disadvantages of synthetic drugs. Among the natural categories, phytoestrogens having a structural similarity of mammalian oestradiol proves its benefit with various mechanisms not only in the treatment of breast cancer but even to prevent the occurrence of postmenopausal symptoms. Phytoestrogens are plant-derived compounds that were utilized in ancient medications and traditional knowledge for its sex hormone properties. Phytoestrogens exert pleiotropic effects on cellular signalling and show effects on estrogen-dependent diseases. However, because of activation/inhibition of steroid hormonal receptor ER-? or ER-?, these compounds induce or inhibit steroid hormonal (estrogen) action and, therefore, have the potential to disrupt hormone (estrogen) signalling pathway. In this review, we have discussed and summarize the effect of certain phytoestrogens and their possible mechanisms that can substantiate advantageous benefits for the treatment of post-menopausal symptoms as well as for breast cancer. � 2020 Elsevier Masson SAS

    A Review on Molecular Mechanism of Flavonoids as Antidiabetic Agents
    (Bentham Science, 2019) Jasmin; Jaitak, Vikas
    The development of drugs possessing anti-diabetic activities is a long pursued goal in drug discovery. It has been shown that deregulated insulin mediated signaling, oxidative stress, obesity, and β-cell dysfunction are the main factors responsible for the disease. With the advent of new and more powerful screening assays and prediction tools, the idea of a drug that can effectively treat diabetes by targeting different pathways has re-bloomed. Current anti-diabetic therapy is based on synthetic drugs that very often have side effects. For this reason, there is an instantaneous need to develop or search new alternatives. Recently, more attention is being paid to the study of natural products. Their huge advantage is that they can be ingested in everyday diet. Here, we discuss various causes, putative targets, and treatment strategies, mechanistic aspects as well as structural features with a particular focus on naturally occurring flavonoids as promising starting points for anti-diabetic led development.
