Resumen
Five previously synthesized 4-trifluoromethyl-2-(5-aryl-3-styryl-1H-pyrazol-1yl)-pyrimidines and six 5-aryl-3-styryl-1-carboxamidino-1H-pyrazole derivatives were screened for their antioxidant proprieties. The antioxidant activities were evaluated by using the DPPH and the HRP/luminol/H2O2 chemiluminescence assay systems and for their antimicrobial activity (MIC). The results were good for those series in some concentration in comparison with the standards. Cinco derivados de 4-trifluorometil-2-(5-aril-3-stiril-1H-pirazol-1il)-pirimidinas e seis 5-aril-3-estiril-1-carboxamidino-1H-pirazois previamente sintetizados foram avaliados de acordo com suas propriedades antioxidantes e antimicrobianas. Estas atividades foram avaliadas por ensaios de DPPH e HRP/luminol/H2O2 quimioluminescência e suas atividades antimicrobianas (CIM). Os resultados foram bons para alguns compostos da série em certas concentrações em comparação direta com padrões.
