Synthesis and Biological Evaluation of Thiosemicarbazide Derivatives Endowed with High Activity toward Mycobacterium Bovis
Thiosemicarbazides are potent intermediates for the synthesis of pharmaceutical and bioactive materials and thus, they are used extensively in the field of medicinal chemistry. The imine bond (-N=CH-) in these compounds are useful in organic synthesis, in particular for the preparation of heterocycles and non-natural β-aminoacids.In this paper the synthesis of some new thiosemicarbazide derivat...

متن کاملDetermination of the recognition sequence of Mycobacterium smegmatis topoisomerase I on mycobacterial genomic sequences.
Mycobacterium smegmatis topoisomerase I has several distinctive features. The absence of the zinc finger motif found in other prokaryotic type I topoisomerases and the ability of the enzyme to recognise single-stranded and duplex DNA are unique characteristics of the enzyme. We have mapped the strong topoisomerase sites of the enzyme on genomic DNA sequences from Mycobacterium tuberculosis and ...
متن کاملSelenium nanoparticles inhibit Staphylococcus aureus growth
Staphylococcus aureus is a key bacterium commonly found in numerous infections. S. aureus infections are difficult to treat due to their biofilm formation and documented antibiotic resistance. While selenium has been used for a wide range of applications including anticancer applications, the effects of selenium nanoparticles on microorganisms remain largely unknown to date. The objective of th...
متن کاملDNA topoisomerase I from Mycobacterium smegmatis.
DNA topoisomerase I has been purified from Mycobacterium smegmatis to near homogeneity using different column chromatographic techniques. The enzyme activity relaxes form I DNA into form IV DNA, requiring Mg2+, but not ATP or any other cofactors for its activity. Several properties of the enzyme were found to be similar to that of the prototype enzyme, Escherichia coli topoisomerase I.
