Synthesis and biological activity of 2-oxo-azetidine derivatives of phenothiazine

We have synthesized of N-[2-(10H-phenothiazinyl)ethyl]-4-(phenyl)-3-chloro-2-oxo-1-iminoazetidine 4(a-m). The structures of all the newly synthesized compounds were confirmed by IR, 1H NMR, 13C NMR and FAB-Mass and chemical methods. All synthesized compounds were evaluated for their antibacterial, antifungal and antitubercular activity which displayed acceptable results.
