A team of researchers from Spain and Latin America have synthesized two iron compounds(complex with qunoxaline derivative below structure) that inhibit the in vitro growth of Mycobacterium tuberculosis, the bacteria that causes tuberculosis. Due their low level of toxicity in mammel cells, the compounds could be used in the future as therapeutic agents and hospital disinfectants.
As per the claim by the researchers, the complexes are better than the second line drugs (we know already about drug resistant tubercular species and tuberculosis is being considered as re-emerging disease due to the increase in the number of people with HIV and other viruses that attack the immune system, as well as to the increasing consumption of immunosuppressive and recreational drugs). Another advantage of the iron compounds is that they show low toxicity in mammal cells, as demonstrated by the experiments performed with mice cells.
"That is why these compounds are useful as hospital disinfectants or therapeutic agents," the Uruguayan researchers highlight, albeit recalling that, at present, they in vitro trials "and the line of research remains open to learn more about how they act."
Researchers conclude that, the novel complexes showed in vitro growth inhibitory activity on Mycobacterium tuberculosis H37Rv (ATCC 27294), together with very low unspecific cytotoxicity on eukaryotic cells (cultured murine cell line J774). Both complexes showed higher inhibitory effects on M. tuberculosis than the “second-line” therapeutic drugs....
