title: Amidine derived 1,3-diazabuta-1,3-dienes as potential antibacterial and antifungal agents.
abstract: Several 1-aryl-2-phenyl-4-piperidino-4-thioalkyl-1,3-diazabuta-1,3-dienes were prepared by the treatment of N-arylimino isothiocyanate with piperidine followed by S-alkylation with alkyl iodides in the presence of dry acetone and potassium hydroxide. The constitution of the products was supported by IR, PMR and mass spectral study. The compounds synthesized were tested in in vitro against E. coli, S. aureus, P. aeruginosa, B. cereus and B. subtilis and fungal stains, Candida albicans and Aspergillus niger. Standard drugs were also tested under identical conditions for comparing the results.
