Reaction of the corresponding 4-acetyl-sydnones with excess hydrazine leads to the hydrazones (I), whereas a 2:1 ratio yields the azines (II). Both product types are screened for their antimicrobial activities. Compounds with halogen substitution on the phenyl ring [cf. (Ic)-(Ie)] exhibit antibacterial effects, whereas methyl group substitution [cf. (Ib)] increases the activity against fungi. (IId) and (IIe) show enhanced antibacterial activity compared to norfloxacin. -(SHINGE, P. S.; MALLUR, S. G.; BADAMI*, B. V.; J. Indian Chem. Soc. 82 (2005) 7, 659-664; Dep.
