BACKGROUND Cissus quadrangularis Linn. (CQ) commonly known as Hadjod (Family: Vitaceae) is usually distributed in India and Sri Lanka and contains several bioactive compounds responsible for various metabolic and physiologic effects. OBJECTIVE In this study, the biological effects of CQ ethanolic extract were evaluated by in vitro and supported by in(More)
Expression of various cytochrome P450s (CYPs) in mammalian brain cells is well documented. However, such studies are hampered in neural/glial cells of human origin due to nonavailability of human brain cells. To address this issue, we investigated the expression and inducibility of CYP2C8 and CYP3A4 and their responsiveness against cyclophosphamide (CPA)(More)
Cigarette smoke derivatives like NNK (4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanone) and NNAL (4-(methylnitrosamino)-1-(3-pyridyl)-1-butan-1-ol) are well-known carcinogens. We analyzed the interaction of enzymes involved in the NER (nucleotide excision repair) pathway with ligands (NNK and NNAL). Binding was characterized for the enzymes sharing equivalent(More)
Of late, a consirable interest has grown in literature on early development of arsenicosis and untimely death in humans after exposure to iAs in drinking water in utero or during the childhood. The mechanism of this kind of intrauterine arsenic poisoning is not known; however it is often suggested to involve stem cells. We looked into this possibility by(More)
Polycyclic aromatic hydrocarbons (PAH), like Benzo[alpha]Pyrene (BaP) are known to cause a number of toxic manifestations including lung cancer. As Titanium dioxide Nanoparticles (TiO2 NPs) have recently been shown to adsorb a number of PAHs from soil and water, we investigated whether TiO2 NPs could provide protection against the BaP induced toxicity in(More)
Hematological changes and concurrent enzymatic activities in various tissues were determined in rats injected parentally with Iomex, a petroleum derivate and proposed weedicide. Among the hematological parameters studied only the differential leucocytic count showed significant alterations. This was indicated by a significant decrease in the number of(More)
A new series of 2,3-cyclopentano-3,4-dihydro-4-spirocyclopentano-1,5-benzodi azepine which are substituted in 5-position with beta-N-heterocycloethyl or gamma-N-heterocyclo-n-propyl groups have been synthesized and evaluated for their CNS depressant activity including anticonvulsant, analgesic and pentobarbital induced hypnosis. These compounds were also(More)
Newly synthesized indolylimidazolones were tested for their in vitro monoamine oxidase (MAO) inhibitory activity. These compounds were found to possess analgesic activity and anticonvulsant activity against maximal electroshock-induced convulsions in mice. The low toxicity of these compounds was reflected by their high approximate LD50 values.
