The ring opening of isochromadiones by prop-2-ynylamine was accomplished in non-polar solvents to form N-prop-2-ynylbenzamide-2-acetic acid 3 N-prop-2-ynylhomophthalimide 4. Compound 3 was found out to be an intermediate product in the formation of 4...
It is quite well known that β-blockers influence the stability of cell membranes, but the effect of metoprolol on the composition of cell membrane lipids is not established. On the other hand, synchronous culture of Chlorella vulgaris cells, which co...
A spectrophotometric method for the selective determination of paracetamol based on its reaction with pyrochatechol violet under basic conditions to form an ion-pair complex is described. The absorption maximum of the coloured ion-pair formed is obse...
A simple and accurate method is described for the quantitative determination of flufenamic acid, mefenamic acid, tranexamic acid, furosemide, diclofenac sodium and thiaprofenic acid by precipitation reactions with nickel(II) followed by direct determ...
We have evaluated vigabatrin (γ-vinyi-γ-aminobutyric acid), an irreversible inhibitor of γ-aminobutyric acid (GABA)-transarninase responsible for GABA degradation, for its effects on nociceptive response, changes in spontaneous locomotor activity and...
In the first detailed study of the flavonoid pattern of Achillea roseo-alba rutin, apigenin-7-O-ß-glucopyranoside, luteolin-7-O-ß-glucopyranoside, isorhamnetin-3-O-rutinoside, schaftoside, luteolin-4’-O-ß-glucopyranoside and 6-OH-luteolin-7-O-ß-gluco...
Seven steroidal saponins were isolated for the first time from the green berries of Solanum unguiculatum. Their structures were determined by spectroscopic analysis as well as hydrolysis of the glycosides into the corresponding sapogenins, diosgenin,...
