Abstract

A series of novel 2-(1H-indol-3-yl)-N-(3, 4-diphenylthiazol-2(3H)-ylidene) ethanamine derivatives (5a-o) were synthesized by cyclization of corresponding 1-(2-(1H-indol-3-yl) ethyl)-3-phenylthiourea 3 with 2-bromoacetophenone. All synthesized compounds were evaluated for in vitro antibacterial activity using Gram-positive bacteria and Gramnegative bacteria. In vitro antifungal activity also determined against the five fungal species. Structures of the synthesized compounds were established by elemental analysis and spectral data.

Keywords: Ethanamine derivatives, Tryptamine, Thiourea, 2-Bromoacetophenone, Antibacterial, Antifungal
