The Development Of Metallohydroxamates As Novel Anti-Bacterial And Anti-Leishmanial Agents, Donal Keogan Jul 2018

The Development Of Metallohydroxamates As Novel Anti-Bacterial And Anti-Leishmanial Agents, Donal Keogan

PhD theses

Since the initial development and clinical use of antibiotics, there has been a steady and alarming increase in the levels of antibiotic resistant bacterial infections arising worldwide. The reduced efficacy of antibiotics coupled to the lack of new classes of antibiotics being developed, may result in antibiotic resistance infections rising to epidemic levels.

The decrease in new antibiotic discovery has resulted in increased interest in repurposing and repositioning of previously developed drugs as effective anti-bacterial treatments. The use of metals in medicine is not a new phenomenon as they have been used in medicine for thousands of years. Nonetheless the ...

Reaction of salicylhydroxamic acid (Sha) and 2-aminophenyl hydroxamic acid (2-NH2-pha) with BiCl3 affords the corresponding novel polymeric bismuth chlorido hydroxamato complexes; [BiCl2(-Sha-1H)]∞ and [BiCl3(--Pha-1H)]∞ respectively. The X-ray crystal structure of the THF-solvated polymeric bismuth chlorido salicylhydroxamato complex, [BiCl2(-Sha-1H)(THF)]∞ was solved, confirming the polymeric structure of this class of compounds and the (O,μ-O’)-bidentate bridging coordination mode of the hydroxamato ligand. The antibacterial activity of the THF-free polymeric bismuth chlorido salicylhydroxamato complex, [BiCl2(-Sha-1H)]∞, was investigated against a broad panel of bacteria, further highlighting the antibacterial properties of Bi-based compounds against Gram-positive and Gram-negative pathogenic and ...
