Abstract

Cinco derivados de 4-trifluorometil-2-(5-aril-3-stiril-1 H-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/H 2 O 2 quimioluminescência e suas atividades antimicrobianas (CIM). Os resultados foram bons para alguns compostos da série em certas concentrações em comparação direta com padrões. Five previously synthesized 4-trifluoromethyl-2-(5-aryl-3-styryl-1 H-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/H 2 O 2 chemiluminescence assay systems and for their antimicrobial activity (MIC). The results were good for those series in some concentration in comparison with the standards.
