For the development of antifungal agents, modification of naftifine which exhibits significant antimycotic activity was performed by replacing the naphthalene ring of it to hete ro cyclic rings such as morpholine. benzothiazole, piperidine and pyridine derivatives. The synthesized compounds were tested in vitro antifungal activity against five different fungi with naftifine as a comparative antimycotic molecule. From the biological evaluation two compounds, (E)-N-(3-phenyl-2-propenyl)-N-(4-piperidinylmethyl)amine(3d) and (E)-N-(3-phenyl-2-propenyl)-N-(3-pyridylmethyl)amine(3f) showed relatively noticeable activity(MIC=50${mu}g$/ml). On the other hand, the other compounds had no activity.
