The present work describes the syntheses and antimicrobial activity studies of a series of novel Schiff bases (4a–4i) and their Mannich bases (5a–5h) starting from 4-amino-3-(N-phthalimido-methyl)-1,2,4-triazole-5-thione (3). All the synthesized compounds were characterized by IR,1H-NMR,13C-NMR, and MS. All the synthesized compounds were screened for four Gram-negative strains, one Gram-positive strain of bacteria, and one diploid fungal strain. In general the antimicrobial activity increased remarkably on the introduction of azomethine functionality in parent triazole (3). The antimicrobial a

Abstract:
Triazole nucleus has drawn much attention since the last decade because of its various potent biological activities. The pharmacological application of triazoles has been widely recognized and well documented. Schiff and Mannich bases are both considered as bioactive compounds, however, there are not much of documentation about the Mannich bases as their study has begun lately. The main aim of this study was to synthesize new Mannich bases from Schiff base bearing 1,2,4-triazole nucleus to access their antimicrobial activities.

Heterocyclic scaffolds reveal extensive biological profiles, and several drugs were employed therapeutically which possess heterocyclic framework. Likewise, 2-substituted benzimidazoles play a significant role in novel drug development. In addition, Mannich and schiff base derivatives of benzimidazole acknowledged them as favorable anti-inflammatory, antimicrobial, anticancer, anthelmintic, antiviral scaffolds.

Abstract:
Mannich bases are beta-amino ketone-carrying compounds that are the end products of the Mannich reaction. The Mannich reaction is essential in the synthesis of nitrogen-containing compounds. The Mannich reaction, a nucleophilic addition reaction that forms carbon-carbon bonds, is employed in the synthesis of numerous natural products, drugs and other compounds. There are several aminoalkyl chain bearing Mannich bases with high curative value, such as fluoxetine, atropine, ethacrynic acid, trihexyphenidyl, and many others. According to the literature, Mannich bases are highly reactive and have
