Quinoxaline 1,4-di-N-oxide and the Potential for Treating Tuberculosis

New drugs active against drug-resistant tuberculosis are urgently needed to extend the range of TB treatment options to cover drug resistant infections. Quinoxaline derivatives show very interesting biological properties (antibacterial, antiviral, anticancer, antifungal, antihelmintic, insecticidal) and evaluation of their medicinal chemistry is still in progress. In this review we report the properties and the recent developments of quinoxaline 1,4-di-N-oxide derivatives as potential anti-tuberculosis agents. Specific agents are reviewed that have excellent antitubercular drug properties, are active on drug resistant strains and non-replicating mycobacteria. The properties of select analogs that have in vivo activity in the low dose aerosol infection model in mice will be reviewed

Antiplasmodial activity of 3-trifluoromethyl-2-carbonylquinoxaline di-N-oxide derivatives

The in vitro antiplasmodial activity of some 3-trifluoromethyl-2-carbonylquinoxaline di-N-oxide derivatives is reported. The evaluation was performed on cultures of FcB1 strain (chloroquine-resistant) of P. falciparum and the most interesting compounds were then evaluated on MCF7 tumor cells in order to evaluate an index of selectivity. The 7-methyl (2b, 4b, 5b, 6b) and nonsubstituted (3c, 4c, 5c) quinoxaline 1,4-dioxide derivatives presented the best level of activity

Mirada iberoamericana a las políticas de ciencia, tecnología e innovación : perspectivas comparadas

El presente libro aporta al campo de los estudios sociales de la ciencia, la tecnología y la innovación, mediante el análisis comparado de los Planes de Ciencia Tecnología e Innovación (PCTI), tratando de superar el enfoque dominante que privilegia los casos nacionales independientes que ha limitado el debate académico. Considera tanto estudios sobre las dinámicas de su institucionalización, el papel de los diversos actores, las contribuciones del campo a la concepción de las políticas y los desafíos que se presentan a las PCTI para responder a los imperativos de democratización, inclusión y sustentabilidad
