2-ACETYLPYRIDINE THIOSEMICARBAZONES .1. NEW CLASS OF POTENTIAL ANTI-MALARIAL AGENTS

Based on the antimalarial properties observed for 2-acetylpyridine 4-phenyl-3-thiosemicarbazone (1), an extensive series of related thiosemicarbazones was prepared and tested against Plasmodium berghei in mice. Screening results indicated that the presence of the 2-pyridylethylidene group was critical and that certain phenyl, benzyl, phenethyl, or cycloalkyl groups at N4 of the thiosemicarbazone moiety also contribute to antimalarial activity. © 1979, American Chemical Society.
