Öğe Astragalin: A Bioactive Phytochemical with Potential Therapeutic Activities(Hindawi Limited, 2018) Riaz A.; Rasul A.; Hussain G.; Zahoor M.K.; Jabeen F.; Subhani Z.; Selamoglu Z.Natural products, an infinite treasure of bioactive chemical entities, persist as an inexhaustible resource for discovery of drugs. This review article intends to emphasize on one of the naturally occurring flavonoids, astragalin (kaempferol 3-glucoside), which is a bioactive constituent of various traditional medicinal plants such as Cuscuta chinensis. This multifaceted compound is well known for its diversified pharmacological applications such as anti-inflammatory, antioxidant, neuroprotective, cardioprotective, antiobesity, antiosteoporotic, anticancer, antiulcer, and antidiabetic properties. It carries out the aforementioned activities by the regulation and modulation of various molecular targets such as transcription factors (NF-B, TNF-?, and TGF-ß1), enzymes (iNOS, COX-2, PGE2, MMP-1, MMP-3, MIP-1?, COX-2, PGE-2, HK2, AChe, SOD, DRP-1, DDH, PLC?1, and GPX), kinases (JNK, MAPK, Akt, ERK, SAPK, IB?, PI3K, and PKCß2), cell adhesion proteins (E-cadherin, vimentin PAR-2, and NCam), apoptotic and antiapoptotic proteins (Beclin-1, Bcl-2, Bax, Bcl-xL, cytochrome c, LC3A/B, caspase-3, caspase-9, procaspase-3, procaspase-8, and IgE), and inflammatory cytokines (SOCS-3, SOCS-5, IL-1ß, IL-4, IL-6, IL-8, IL-13, MCP-1, CXCL-1, CXCL-2, and IFN-?). Although researchers have reported multiple pharmacological applications of astragalin in various diseased conditions, further experimental investigations are still mandatory to fully understand its mechanism of action. It is contemplated that astragalin could be subjected to structural optimization to ameliorate its chemical accessibility, to optimize its absorption profiles, and to synthesize its more effective analogues which will ultimately lead towards potent drug candidates. © 2018 Ammara Riaz et al.Öğe Determination of anti-oxidative, anti-microbial activity and heavy metal contents of Leucoagaricus leucothites(NLM (Medline), 2018) Sevindik M.; Rasul A.; Hussain G.; Anwar H.; Zahoor M.K.; Sarfraz I.; Selamoglu Z.Mushrooms, a treasure of diverse bioactive scaffolds, have been widely admired due to their nutritional and medicinal significance all over the world. The current study intended to evaluate the therapeutic potentiality of an edible mushroom, Leucoagaricus leucothites (Vittad.) Wasser. Thus, anti-oxidant potential of L. leucothites was determined using DPPH assay and for the determination of anti-microbial potential agar dilution procedure was followed. TOS (total oxidant status), TAS (total anti-oxidant status), and OSI (oxidative stress index) values were evaluated utilizing Rel Assay Kits. For the assessment of heavy metal contents, wet decomposition approach with atomic absorption spectrophotometry was adopted. Screening of phytochemicals present in ethanolic extract of L. leucothites were determined by HPLC. TAS, TOS and OSI values were found to be 8.291mmol/L, 10.797µmol/L and 0.130 respectively. Our results declared that heavy metal contents are generally in the safe range. Phytochemical analysis of L. leucothites has affirmed the presence of important phenolics such as gallic acid, catechin, and hesperidin. Investigations on anti-oxidant and anti-microbial potential of L. leucothites has uncovered the fact that this naturally occurring, biologically active, and therapeutically effective mushroom specie has natural borne anti-oxidant and anti-microbial potential and it would be worthwhile to use it for nutritional as well as medicinal purpose.Öğe Malic enzyme 2 as a potential therapeutic drug target for cancer(Blackwell Publishing Ltd, 2018) Sarfraz I.; Rasul A.; Hussain G.; Hussain S.M.; Ahmad M.; Nageen B.; Ali M.Reprogrammed metabolic profile is a biochemical fingerprint of cancerous cells, which represents one of the “hallmarks of cancer.” The aberrant expression pattern of enzymatic machineries orchestrates metabolic activities into a platform that ultimately promotes cellular growth, survival, and proliferation. The NADP(+)-dependent mitochondrial malic enzyme 2 (ME2) has been widely appreciated due to its function as a provider of pyruvate and reducing power to the cell for biosynthesis of fatty acids and nucleotides along with maintenance of redox balance. Multiple lines of evidences have indicated that ME2 is a bonafide therapeutic target and novel biomarker which plays critical role during tumorigenesis. The objective of this review is to provide an update on the cancer-specific role of ME2 in order to explore its potential for therapeutic opportunities. Furthermore, we have discussed the potential of genetic and pharmacological inhibitors of ME2 in the light of previous research work for therapeutic advancements in cancer treatment. It is contemplated that additional investigations should focus on the use of ME2 inhibitors in combinational therapies as rational combinations of metabolic inhibitors and chemotherapy may have the ability to cure cancer. © 2018 IUBMB Life, 70(11):1076–1083, 2018. © 2018 International Union of Biochemistry and Molecular BiologyÖğe Nature-Inspired Drugs: Expanding Horizons of Contemporary Therapeutics(Hindawi Limited, 2019) Rasul A.; Hussain G.; Selamoglu Z.; López-Alberca M.P.[No abstract available]
