Synthetic studies on leupeptins and their analogs.
Leupeptins, fermentation products of various strains of Actinomycetes^ showed strong antiplasmin activity2) and were identified as being a mixture of two major components, leupeptin Ac-LL (acetyl-L-leucyl-L-leucyl-DL-argininal, 1) and leupeptin Pr-LL (propionyl-L-leucyl-L-leucyl-DL-argininal, 2), and their analogs containing isoleucine or valine in place of one or two leucine residues of 1 or 2...
متن کاملStudies with mouse pituitary thyrotropic tumors. V. Effect of various thyroxine analogs on growth and secretion.
A number of thyroxine derivatives have been studied for effects on growth and secretory ac tivity of mouse pituitary thyrotropic tumors. Three tumors, dependent-responsive (4183), auton omous responsive (L24), and autonomous nonresponsive (L23), were employed. No unique abil ity to suppress tumor growth was demonstrated, and most of the analogs were found to be inactive. Augmentation in growth ...
متن کاملX-ray studies on phospholipid bilayers. XI. Interactions with chloramphenicol.
Chloramphenicol is a widely used antibiotic with low levels of toxicity. However, scanning electron microscopy revealed morphological changes in human erythrocytes when they interacted in vitro with therapeutical concentrations of chloramphenicol. To explain this shape change, a study concerned with the possible interactions of this antibiotic with bilayers built-up of phospholipids located in ...
متن کاملStudies on the binding of carboxin analogs to succinate dehydrogenase.
Carboxin (5,6-dihydro-2-methyl-l,4-oxathiin-3-carboxanilide) and a number of other carboxanilides are known to be potent inhibitors of succinate oxidation in membrane preparations from animal tissues, fungi, and bacteria, acting at the succinate dehydrogenase-coenzyme Q junction. The kinetics and the maximal extent of inhibition of succinate oxidation by carboxanilides and by thenoyltrifluoroac...
متن کاملSynthesis, Characterization and Antimicrobial Studies on Some Newer Imidazole Analogs
A novel series of 3,5-diiodo-4-(2-methyl-1H-imidazol-5-yl)benzoic acid analogs of amino acids, dipeptides and tripeptides was synthesized by using dicyclohexylcarbodiimide and diisopropylcarbodiimide (DCC/DIPC) as coupling agents and triethylamine (TEA) as base. Structures of all the newly synthesized compounds were confirmed by elemental analysis and IR, H NMR, C NMR and mass spectral data. Im...
