We studied the effects of inhibitors of ornithine decarboxylase (ODC), arginine decarboxylase (ADC) and spermidine synthase (Spd synthase) on organogenesis and the titers of polyamines (PA) and alkaloids in tobacco calli. DL-alpha-diffluromethylarginine (DFMA) and D-arginine (D-Arg), both inhibitors of ADC

Dicyclohexylamine, which is an inhibitor of bacterial and mammalian spermidine synthase, greatly inhibited the synthesis of spermidine in Pseudomonas aeruginosa. The depletion of spermidine caused by dicyclohexylamine was accompanied by an inhibition of growth of bacteria. This inhibition was reversed

A simple, selective, sensitive, accurate and relatively inexpensive method for the determination of palladium in bulk pharmaceutical chemicals (BPC) and their synthetic intermediates by graphite furnace atomic absorption spectroscopy has been developed and validated. Sample preparation by direct dissolution of
Hyperforin has been identified as an active constituent of Hypericum perforatum but its importance in the antidepressant effect of this plant's extracts is not really known. To evaluate the antidepressant-like activity of two extracts in relation to the content of
Because of the extremely heterogeneous distribution of explosives in contaminated soils, on-site colorimetric methods are efficient tools to assess the nature and extent of contamination. To meet the need for rapid and low-cost chemical sensing of explosive traces or residues
