Novel Benzimidazol‐2‐Thione Derivatives: Synthesis, In Vitro Anticancer, Antimicrobial Activities, And In Silico Molecular Docking Study

Abstract

AbstractA series of derivative benzimidazol‐2‐thione compounds (2 a–2 l) had been synthesized, screened for their antimicrobial activities by dish diffusion and dilution assays, anti‐tumor against breast, rhabdomyosarcoma, and liver human cancer cell lines via MTT assay, followed by carrying out in silico docking model. Entries 2 i–2 j, 2 l, and 2 g are novel compounds, among them, compound 2i manifested the highest antibacterial activity against both Methicillin‐resistant Staphylococcus aureus and Streptococcus faecalis; meanwhile, entries 2 i–2 j and 2 l showed significant antifungal activity toward Trichophyton mentagrophytes, Trichophyton rubrum, and Microsporum gypseum. Through in vitro approach, entry 2 i is the best derivative against human rhabdomyosarcoma cell line. Additionally, via in silico approach, entry 2 i reasonably explained drug delivery ligand against bacterium Streptococcus faecalis, moreover, entries 2 i–2 j and 2 l showed excellent antifungal activity, explained via enzyme inhibition mechanism against 2VF5. In silico, 2 i was proved to inhibit against sarcoma cancer cell line.
