The manuscript reports the green-chemical synthesis of a new diindole-substituted benzimidazole compound, B1 through a straightforward route in coupling between indolyl-3-carboxaldehyde and o-phenylenediamine in water medium under the aerobic condition at 75 ºC. The single crystal X-ray structural analysis of B1 suggests that the disubstituted benzimidazole compound crystallizes in a monoclinic system and the indole groups exist in a perpendicular fashion with respect to benzimidazole moiety. The SARS-CoV-2 screening activity has been studied against 1 × 10e4 VeroE6 cells in a dose-dependent manner following Hoechst 33342 and nucleocapsid staining activity with respect to remdesivir. The compound exhibits 92.4% cell viability for 30 h and 35.1% inhibition against VeroE6 cells at non-cytotoxic concentration. Molecular docking studies predict high binding propensities of B1 with the main protease (M) and non-structural (nsp2 and nsp7-nsp8) proteins of SARS-CoV-2 through a number of non-covalent interactions. Molecular dynamics (MD) simulation analysis for 100 ns confirms the formation of stable conformations of B1-docked proteins with significant changes of binding energy, attributing the potential inhibition properties of the synthetic benzimidazole scaffold against SARS-CoV-2.

Despite ongoing advancements in drug design and developments, breast cancer remains a serious and devastating disease and is ranked as the second most common illness in women. Breast cancer rates have increased significantly during the last 40 years. This necessitates the development of novel treatment techniques.

Heterocyclic compounds are increasingly used in medicinal chemistry because they are the main components of many biological processes and materials. Benzimidazole remains the core center of the heterocyclic chemical group, with essential traits such as six-five-member connected rings and two nitrogen atoms at the 1,3 position in a six-membered benzene and five-membered imidazole- fused ring system. Molecules with benzimidazole derivatives serve important functions as therapeutic agents and have shown excellent results in clinical and biological research.

Four years after the COVID-19 pandemic, a very limited number of drugs has been marketed; thus, the search for new medications still represents a compelling need. In our previous work on antiviral, antiparasitic, and antiproliferative agents, we described several compounds (- and -) structurally related to clofazimine, chloroquine, and benzimidazole derivatives. Thus, we deemed it worthwhile to test them against the replication of SARS-CoV-2, together with a few other compounds (, and -), which showed some analogy to miscellaneous anti-coronavirus agents.

For over three decades, praziquantel (PZQ) has been the mainstay chemotherapy for prevention and treatment of schistosomiasis. The excessive use of PZQ, coupled with the lack of advanced drug candidates in the current anti-schistosomiasis drug development pipeline, emphasizes the genuine need for new drugs. In the current work, we investigated the antischistosomal potential of a new series of compounds derived from the privileged benzimidazole scaffold, which exhibited low micromolar IC potency in the range of 1.

New derivatives 6a-m with benzimidazole-indole-amide scaffold were developed, synthesized, and assessed for potential inhibitory effects on α-glucosidase and acetylcholinesterase (AChE). These compounds were synthesized by various amine derivatives. With the exception of two compounds, the α-glucosidase inhibitory activities of the title derivatives were more than that of the positive control acarbose.
