TL;DR: The results infer that NMDA antagonist MK801 and memantine are effective against OKA-induced neurotoxicity, and clearly indicates the involvement of NMDA receptor in OKA (ICV)-induced Tau hyperphosphorylation.

TL;DR: Making analogues of the most potent molecule for developing synthetic series with rational drug design approach could pay rich dividends in menopausal osteoporosis therapy.
Abstract: Substantial body of data generated from cultured bone cells and rat models of osteoporosis supports a significant bone-conserving effect of phytochemicals. Flavonoids including isoflavones, stilbenes and lignans with variable efficacy have shown promising therapeutic application in osteoporosis. Majority of the phytochemicals assessed for their effects on bone cells revealed multiple beneficial actions such as promoting osteoblast functions, and inhibiting osteoclast and adipocyte functions. A variety of molecular targets mediate multiple effects of phytochemicals in bone cells. In vivo, quite a few phytochemicals have been found to afford bone-sparing effect and in some cases even bone restoring effect. However, important pharmacokinetic and bioavailaibility studies associated with these phytochemicals are mostly lacking. As a result, translating these findings to the clinic has been challenging, and so far only a few clinical studies have attempted to evaluate the effect of phytochemicals in menopausal osteoporosis. Clinical studies so far performed are with dietary supplements rather than pure phytochemicals. Clinical trials with pure molecules necessitate preclinical regulatory and safety studies that are not available with the phytochemicals except ipriflavone with bone-conserving properties. Ipriflavone is the only marketed anti-osteoporosis agent that was obtained following a lead from natural substance. As phytochemicals have multiple beneficial influences on bone cells, making analogues of the most potent molecule for developing synthetic series with rational drug design approach could pay rich dividends in menopausal osteoporosis therapy.

TL;DR: The role of ascorbate in the modulation of NO‐mediated ROS generation from PMNs is delineated and it is indicated that inhibitors of DHA uptake, reduced nicotinamide adenine dinucleotide phosphate oxidase, NO synthase, or ROS scavengers attenuated ROS generation.
Abstract: Recent studies from our laboratory have demonstrated that ascorbate potentiated enzymatic synthesis of nitric oxide (NO) from polymorphonuclear leukocytes (PMNs). NO is known to modulate various function of PMNs such as chemotaxis, adherence, aggregation, and generation of reactive oxygen species (ROS). The role of ascorbate in the PMN phagocytosis, ROS generation, and apoptosis was thus evaluated in the present study. Ascorbate and its oxidized and cell-permeable analog, dehydroascorbate (DHA), did not affect the phagocytosis but enhanced ROS generation and apoptosis following treatment with Escherichia coli or arachidonic acid. A detailed investigation on the DHA-mediated response indicated that inhibitors of DHA uptake, reduced nicotinamide adenine dinucleotide phosphate oxidase, NO synthase, or ROS scavengers attenuated ROS generation. In DHA-treated cells, enhanced generation of peroxynitrite was also observed; thus, ascorbate-mediated ROS and reactive nitrogen species generation might mediate cytotoxicity toward the ingested microbes and subsequently, augmented PMN apoptosis. Results of the present study have helped in delineating the role of ascorbate in the modulation of NO-mediated ROS generation from PMNs.
