    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.
