Abstract
In this study, a series of new benzimidazole-thiadiazole hybrids were synthesized, and the synthesized compounds were screened for their antimicrobial activities against eight species of pathogenic bacteria and three fungal species. Azithromycin, voriconazole, and fluconazole were used as reference drugs in the mtt assay. Among them, compounds 5f and 5h showed potent antifungal activity against C. albicans with a MIC of 3.90 μg/mL. Further, the results of the antimicrobial assay for compounds 5a, 5b, 5f, and 5h proved to be potent against E. faecalis (ATCC 2942) on the basis of an acceptable MIC value of 3.90 μg/mL. The cytotoxic effects of compounds that are effective as a result of their antimicrobial activity on healthy mouse fibroblast cells (L929) were evaluated. According to HOMO-LUMO analysis, compound 5h (with the lower ΔE = 3.417 eV) is chemically more reactive than the other molecules, which is compatible with the highest antibacterial and antifungal activity results. A molecular docking study was performed to understand their binding modes within the sterol 14-α demethylase active site and to interpret their promising fungal inhibitory activities. Molecular dynamics (MD) simulations of the most potent compounds 5f and 5h were found to be quite stable in the active site of the 14-α demethylase (5TZ1) protein.

Abstract
In the present study, we used benzimidazolone as a starting material to efficiently synthesize several hybrid compounds of pyrazole benzimidazolone derivatives by the 1,3-dipolar cycloaddition reaction. These compounds were obtained in average yields and were characterized by NMR (1H and 13C) and HRMS analysis. The antioxidant activity of the synthesized compounds 5(a-c) and 6(a-c) was evaluated using in vitro reduction assays, including ferric reducing antioxidant power (FRAP) and total antioxidant capacity (TAC). The results indicated that products 5c, 6b, and 6c exhibit higher antioxidant activity compared to the reference compounds and showed a remarkable ability to effectively remove the radical at IC50 (14.00 ± 0.14, 12.47± 0.02, and 12.82 ± 0.10 µM, respectively) under the TAC assessment. Conversely, compound 6c showed excellent activity at IC50 (68.97 ± 0.26 µM) in the FRAP assay. We carried out molecular docking and dynamics simulations to investigate the binding mode and stability of 5c, 6b, and 6c in the active site of human Peroxiredoxin 5. An ADMET study was conducted to determine the drug properties of the synthesized compounds.

Abstract
The polymorphic structures (I and II) of 3-phenyl-1H-1,3-benzo-diazol-2(3H)-one, C13H10N2O, acquired from pentane diffusion into the solution in THF, are reported. The structures show negligible differences in bond distances and angles, but the C-N-C-C torsion angles between the backbone and the phenyl substituent, 123.02 (15)° for I and 137.18 (11)° for II, are different. Compound I features a stronger C=O⋯H-N hydrogen bond than that in II, while the structure of II exhibits a stronger π-π inter-action than in I, as confirmed by the shorter inter-centroid distance [3.3257 (8) Å in II in comparison to 3.6862 (7) Å in I]. Overall, the supra-molecular inter-actions of I and II are distinct, presumably originating from the variation in the dihedral angle.

Abstract
Compounds containing benzimidazole moiety occupy privileged chemical space for discovering new bioactive substances. In continuation of our recent work, 69 benzimidazole derivatives were designed and synthesized with good to excellent yields of 46-99% using efficient synthesis protocol i.e. sodium metabisulfite catalyzed condensation of aromatic aldehydes with o-phenylenediamines to form 2-arylbenzimidazole derivatives followed by N-alkylation by conventional heating or microwave irradiation for diversification. Potent antibacterial compounds against MSSA and MRSA were discovered such as benzimidazole compounds 3k (2-(4-nitrophenyl), N-benzyl), 3l (2-(4-chlorophenyl), N-(4-chlorobenzyl)), 4c (2-(4-chlorophenyl), 6-methyl, N-benzyl), 4g (2-(4-nitrophenyl), 6-methyl, N-benzyl), and 4j (2-(4-nitrophenyl), 6-methyl, N-(4-chlorobenzyl)) with MIC of 4-16 μg mL-1. In addition, compound 4c showed good antimicrobial activities (MIC = 16 μg mL-1) against the bacteria strains Escherichia coli and Streptococcus faecalis. Moreover, compounds 3k, 3l, 4c, 4g, and 4j have been found to kill HepG2, MDA-MB-231, MCF7, RMS, and C26 cancer cells with low μM IC50 (2.39-10.95). These compounds showed comparable drug-like properties as ciprofloxacin, fluconazole, and paclitaxel in computational ADMET profiling. Finally, docking studies were used to assess potential protein targets responsible for their biological activities. Especially, we found that DHFR is a promising target both in silico and in vitro with compound 4c having IC50 of 2.35 μM.

Abstract
A new series of 6-substituted 1H-benzimidazole derivatives were synthesized by reacting various substituted aromatic aldehydes with 4-nitro-o-phenylenediamine and 4-chloro-o-phenylenediamine through condensation using sodium metabisulfite as the oxidative reagent. The N-substituted 6-(chloro/nitro)-1H-benzimidazole derivatives were prepared from the 6-substituted 1H-benzimidazole derivatives and substituted halides using potassium carbonate by conventional methods as well as by exposure to microwave irradiation. Seventy-six 1H-benzimidazole derivatives have been synthesized in moderate to excellent yields with the microwave-assisted method (40 to 99%). Compounds 1d, 2d, 3s, 4b, and 4k showed potent antibacterial activity against Escherichia coli, Streptococcus faecalis, MSSA (methicillin-susceptible strains of Staphylococcus aureus), and MRSA (methicillin-resistant strains of Staphylococcus aureus) with MIC (the minimum inhibitory concentration) ranging between 2 and 16 μg mL−1 as compared to ciprofloxacin (MIC = 8–16 μg mL−1), in particular compound 4k exhibits potent fungal activity against Candida albicans and Aspergillus niger with MIC ranging between 8 and 16 μg mL−1 compared with the standard drug fluconazole (MIC = 4–128 μg mL−1). In addition, compounds 1d, 2d, 3s, 4b, and 4k also showed the strongest anticancer activity among the synthesized compounds against five tested cell lines with IC50 (half-maximal inhibitory concentration) ranging between 1.84 and 10.28 μg mL−1, comparable to paclitaxel (IC50 = 1.38–6.13 μM). Furthermore, the five most active compounds showed a good ADMET (absorption, distribution, metabolism, excretion, and toxicity) profile in comparison to ciprofloxacin, fluconazole, and paclitaxel as reference drugs. Molecular docking predicted that dihydrofolate reductase protein from Staphylococcus aureus is the most suitable target for both antimicrobial and anticancer activities, and vascular endothelial growth factor receptor 2 and histone deacetylase 6 are the most suitable targets for anticancer activity of these potent compounds. The purpose of this study is to synthesize novel N-substituted 6-(chloro/nitro)-1H-benzimidazole derivatives with various substituted aryl groups at position 2 and alkylation at position 1, and evaluate their antimicrobial and anticancer activities.![]()

Abstract
Target prediction is a crucial step in modern drug discovery. However, existing experimental approaches to target prediction are time-consuming and costly. Here, we introduce LigTMap, an online server with a fully automated workflow that can identify protein targets of chemical compounds among 17 classes of therapeutic proteins extracted from the PDBbind database. It combines ligand similarity search with docking and binding similarity analysis to predict putative targets. In the validation experiment of 1251 compounds, targets were successfully predicted for more than 70% of the compounds within the top-10 list. The performance of LigTMap is comparable to the current best servers SwissTargetPrediction and SEA. When testing with our newly compiled compounds from recent literature, we get improved top 10 success rate (66% ours vs. 60% SwissTargetPrediction and 64% SEA) and similar top 1 success rate (45% ours vs. 51% SwissTargetPrediction and 41% SEA). LigTMap directly provides ligand docking structures in PDB format, so that the results are ready for further structural studies in computer-aided drug design and drug repurposing projects. The LigTMap web server is freely accessible at https://cbbio.online/LigTMap. The source code is released on GitHub (https://github.com/ShirleyWISiu/LigTMap) under the BSD 3-Clause License to encourage re-use and further developments.

Abstract
Global advancements in biological technologies have vastly increased the variety of and accessibility to bioassay platforms, while simultaneously improving our understanding of druggable chemical space. In the South African context, this has resulted in a rapid expansion in the number of medicinal chemistry programmes currently operating, particularly on university campuses. Furthermore, the modern medicinal chemist has the advantage of being able to incorporate data from numerous related disciplines into the medicinal chemistry process, allowing for informed molecular design to play a far greater role than previously possible. Accordingly, this review focusses on recent highlights in drug-discovery programmes, in which South African medicinal chemistry groups have played a substantive role in the design and optimisation of biologically active compounds which contribute to the search for promising agents for infectious disease.

Abstract
Twenty-seven derivatives (40-66) were generated by pharmacophore fusing of sulfonylacetanilide-diarylpyrimidine (1) with rilpivirine or biphenyl-diarylpyrimidines. They displayed up to single-digit nanomolar activity against wild-type (WT) virus and various drug-resistant mutant strains in HIV-1-infected MT-4 cells, thereby targeting the reverse transcriptase (RT) enzyme. Compound 51 displayed exceptionally potent activity against WT virus (EC50 = 6 nM) and several mutant strains (L100I, EC50 = 8 nM, K103N, EC50 = 6 nM, Y181C, EC50 = 26 nM, Y188L, EC50 = 122 nM, E138K, EC50 = 26 nM). The structure-activity relationships of the newly obtained pyrimidine sulfonylacetanilides were also elucidated. Molecular docking analysis explained the activity and provided a structural insight for follow-up research.
