✦ Synopsis


Four new 3-[4-(alkoxycarbonyl)phenyl]sydnones have been synthesised. The hydrazide 4 is condensed with various aromatic aldehydes to obtain the corresponding Schiff bases. Antimicrobial activities of the sydnones and some Schiff bases are reported. Mass spectral fragmentation of 3[4-(ethoxycarbonyl)phenyl]sydnone is discussed.

Synthese und biologische Aktivitit von 3-(p-AJkoxycarbonylpbenyl)-sydnonen und ihren Derivaten

Vier neue 3-(p-Alkoxycarbonylphenyl)-sydnone wurden hergestellt. Das Hydrazid 4 wurde mit verschiedenen aromatischen Aldehyden kondensiert, um die entsprechenden Schiffschen Basen zu erhalten. Uber die antimikrobielle Aktivitat aller Sydnone und einiger Schiffscher Basen wird berichtet. Die ms Fragmentierung von 3-(p-Ethoxycarbonylphenyl)-sydnon wird diskutiert.

Among the various mesoionic systems, sydnones are known to exhibit a wide range of biological properties','). Many sydnone derivatives synthesised from this laboratory have shown antibacterial3), antiinflammat~ry~) and CNS depression5) properties. The pharmacological utility of hydrazones in tubercul~sis~.~) prompted us to investigate sydnones possessing these groups.
