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 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 کاملChemical modification of group IV graphene analogs
Mono-elemental two-dimensional (2D) crystals (graphene, silicene, germanene, stanene, and so on), termed 2D-Xenes, have been brought to the forefront of scientific research. The stability and electronic properties of 2D-Xenes are main challenges in developing practical devices. Therefore, in this review, we focus on 2D free-standing group-IV graphene analogs (graphene quantum dots, silicane, an...
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...
