In vitro Evaluation of Kigelia pinnata Leaves for Its Antioxidative and Anticancer Activity
Abstract: Previous studies suggest that the Kigelia pinnata leaves have useful effects against diseases mediated through oxidative stress and cancers. In this study, leaves of Kigelia pinnata were studied for presence of different phytochemical constituents, anti-oxidant and anti-cancer activities.Crude methane extracts of Kigelia pinnata leaves showed cytotoxic activity in vitro against non-small cell lung cancinoma (A-549) cells using the MTT assay. Phytochemical evaluation showed the existence of alkaloids, terpenoids, flavonoids, tannins …

PHD-2 Activation to Stabilize HIF-1α and FASN in Mammary Gland Cancer
Abstract: Activation of prolyl hydroxylase-2 (PHD2) has emerged as an attractive target to counteract tumor hypoxia and thereby uncontrolled cellular proliferation. We utilized an integrated strategy to identify new PHD2 activators using series of in silico tools and in vitro methods. The in silico screening helped to identify 4-ethyl-3-(4-methoxyphenyl)-2,2-dimethyl-2H-chromen-7-yl acetate (BBAP-3), [4-(7-acetyloxy-4-ethyl-2,2-dimethylchromen-3-yl)phenyl]acetate (BBAP-4), 3-(4-methoxyphenyl)-2,2,4-trimethyl-2H-chromen-7-yl acetate (BBAP-5) as an activator, who are structurally similar to KRH102140 (a known activator of PHD2). All …

Alteration in Metabolic Enzymes of Albino Rats under Cadmium Stress and their Modulation by Mentha Piperita
Abstract: Cadmium is a heavy metal posing severe risks to human health without any physiological function in the human body. Cadmium is found regularly in soil, rocks and ores, thus natural exposure is an important aspect, but increasing industrial application has put it in the category of bio-hazardous metals. Anticorrosive agents, stabilizer in PVC products, colour pigments, neutron-absorber in nuclear power plants, the fabrication of nickel-cadmium batteries and Phosphate fertilizers carry …

Sub-acute Toxicity of β-cyfluthrin in Hepatic Tissue and its Amelioration through Punica granatum in Swiss albino mice
Abstract: β-cyfluthrin, member of synthetic pyrethroid pesticide Type II is broadly used multipurpose insecticide. Widespread and indiscriminate use of β-cyfluthrin leads to environmental contamination and toxicity towards nontarget mammalian systems. The present study was undertaken to examine toxic manifestation of β-cyfluthrin in hepatic tissue of Swiss albino mice and also evaluate possible mitigative potential of pomegranate juice (PJ) in combating pesticide induced hepato-toxicity. Animals were divided into five groups namely, control, …
