In vitro antimicrobial activity of some cyclic hydroxamic acids and related lactams

Antimicrobial activity of some hydroxamic acids.

Several hydroxamic acids, viz., N-benzyl-N'-hydroxysuccinamide (BHS), poly[alpha,beta-(N-hydroxy)-DL-aspartamide] (PHA), poly[alpha,beta-(N-hydroxy-N-methyl-DL-aspartamide)] (PMHA) and poly[alpha,beta-(N-hydroxy)-DL- aspartamide]/poly[alpha,beta-(N-2-hydroxyethyl)-DL-aspartamide] (PHA-PHEA 1:1) were prepared and screened for their antimicrobial activity. Ten Gram-positive and 7 Gram-negative sp...

Title of Thesis SYNTHESIS AND ANTIMICROBIAL ACTIVITY OF SOME HYDROXAMIC ACIDS

Physiological role of the cyclic hydroxamic acids

Roots of young seedleings of barnyard grass, maize, rye and wheat secret hydroxamic acids. Their compexes with Fe/III/-ions are available sources of iron. It is possible that the cyclic hydroxamic acids play a role in the alternative mechanism of iron uptake. The hydroxamic acids secreted by barnayard grass roots have an allelopathic role by inhibiting the roots growth of rice. Acta Biol Szeged...

Mutagenicity and antibacterial activity of hydroxamic acids.

Hydroxamic acids demonstrated mutagenic and antibacterial activities. These activities appear to be dependent on the hydroxamic acid function and are probably due to the interaction with deoxyribonucleic acid.
