To study racemic bupivacaine, non-racemic bupivacaine and ropivacaine on myocardial contractility. Isolated Wistar papillary muscles were submitted to 50 and 100 mM racemic bupivacaine (B50 and B100), non-racemic bupivacaine ...

omeprazole is a substituted benzimidazole which suppresses gastric-acid secretion by means of H+, K+-ATPase inhibition. It is an optically active drug with the sulfur of the sulfoxide being the chiral center. This pro-drug ...

This study evaluates the influence of the raceme position in the plant, the fruit position in the raceme, and the storage period on the chemical composition of castor beans. The experiment was initially performed in field, ...

The alkyl chain of anatoxin-a(s) (cyclic guanidines), which can be used as an intermediate in the total synthesis of anatoxin-a(s), was synthesized in both racemic and enantiomerically pure forms. These enantiomerically ...

Synthesis, characterization and crystal structure for racemic ONNO Schiff base ligand 3-OMe-t-salcn (trans-N,N’-bis(3-methoxysalicylidene)-1,2-cyclohexanediamine) and its vanadyl and uranyl complexes are reported. Both ...

The present research had as objective to evaluate the influence of raceme and fruit position on physiological quality of castor bean seeds (Ricinus communis L.) during storage of cultivar AL Guarany 2002. The treatments ...
