Two Antimycin A Analogues from Marine-Derived Actinomycete Streptomyces lusitanus
Two new antimycin A analogues, antimycin B1 and B2 (1-2), were isolated from a spent broth of a marine-derived bacterium, Streptomyces lusitanus. The structures of 1 and 2 were established on the basis of spectroscopic analyses and chemical methods. The isolated compounds were tested for their anti-bacterial potency. Compound 1 was found to be inactive against the bacteria Bacillus subtilis, St...
متن کاملIsostreptazolin and sannaphenol, two new metabolites from Streptomyces sannanensis.
Two new compounds, isostreptazolin (1) and sannaphenol (2), were isolated from the culture broth of Streptomyces sannanensis and their structures elucidated on the basis of 1D and 2D NMR as well as MS, IR and UV spectroscopic data analysis. The cytotoxic activity of 1 and 2 were evaluated. Both compounds were inactive against H460 and HeLa cell lines at 100 mM.
متن کاملProperties of two homologous alkaline proteases from Streptomyces rectus.
Some physicochemical properties of two thermostable proteases from Streptomyces rectus are described. The enzymes were judged to be identical with respect to molecular weight, inactivation with serine protease inhibitors, and in primary structure by peptide analysis. Amino acid analysis indicated the enzymes had identical compositions except for their amide content. The molecular weights of the...
متن کاملTue Chemical Basis of Biological Mutation
Since the realisation that the genetic material in living organisms is deoxyribonucleic acid (DNA) [or ribonucleic acid (RNA) in RNA-containing viruses], the way has, in principle, been open for an attack on the question of the chemical basis of biological mutation. In this paper I wish to draw some conclusions respecting one mutagen, but, more importantly, try to demonstrate the nature of the ...
متن کاملInfluence of Tue Electronic Suellstructure on Tue Elastic Scattering of Heavyions1;(
The interatomic potential of the system I-I at intermediate and small distances is calculated from atomic DFS electron densities within a statistical model. Structures in the potential, due to the electronic shells, are investigated. Calculations of the elastic differential scattering cross section for sma1l angles and several keV impact energies show a detailed peak pattern which can be correl...
