Ginkgolide B, the major active component of Ginkgo biloba extracts, can bothstimulate and inhibit apoptotic signaling. Here, we demonstrate that ginkgolide B caninduce the production of reactive oxygen species in MCF-7 breast cancer cells, leading to...
Acetylcholinesterase (AChE) activities in different brain parts were determinedquantitatively in rats treated with huperzine A, soman, and huperzine A followed bysoman, using histochemical and biochemical methods. Following soman intoxication (1.2x L...
The paper presents a unitary approach of the use of a Molecular DescriptorsFamily in structure-property/activity relationships, particularly in modelling thechromatographic retention times of polychlorinated biphenyls. Starting from molecularstructur...
We report the measured total charge-transfer (electron-capture) cross sectionsfor the ground state O2+ (X2πg) ions with H2 and O2 molecular gases in the collisionenergy range between 0.50 and 2 keV. The time-of-flight technique has been used tomeasur...
A set of 13 fatty acids was transformed into their phenacyl esters by reaction withphenacyl bromide in acetonitrile using 18-crown-6 as phase-transfer catalyst. Conditions forthe RP-18 HPL chromatographic separation of most of the esters has been wor...
The objectives of this study were to isolate various isoflavone fractions andextracts from soybean cake by preparative column chromatography and compare themwith isoflavone standards with regards to inhibition of HepG2 cancer cell proliferation.Four...
ATP is involved in numerous biochemical reactions in living cells interacting withdifferent proteins. Molecular docking simulations provide considerable insight into theproblem of molecular recognition of this substrate. To improve the selection of c...
Geometric parameters and FT-IR spectrum of 6-bromo-8-thia-1,4-epoxybicyclo[4.3.0]non-2-ene were computed by the HF, B3LYP, B3PW91 andmPW1PW91 methods in conjunction with the 6-31G(d,p) basis set. The calculated IRspectra are in a good agreement with...
