Abstract
Improving lipophilicity for drugs to penetrate the lipid membrane and decreasing bacterial and fungal coinfections for patients with cancer pose challenges in the drug development process. Here, a series of new N-alkylated-2-(substituted phenyl)-1H-benzimidazole derivatives were synthesized and characterized by 1H and 13C NMR, FTIR, and HRMS spectrum analyses to address these difficulties. All the compounds were evaluated for their antiproliferative, antibacterial, and antifungal activities. Results indicated that compound 2g exhibited the best antiproliferative activity against the MDA-MB-231 cell line and also displayed significant inhibition at minimal inhibitory concentration (MIC) values of 8, 4, and 4 μg mL-1 against Streptococcus faecalis, Staphylococcus aureus, and methicillin-resistant Staphylococcus aureus compared with amikacin. The antifungal data of compounds 1b, 1c, 2e, and 2g revealed their moderate activities toward Candida albicans and Aspergillus niger, with MIC values of 64 μg mL-1 for both strains. Finally, the molecular docking study found that 2g interacted with crucial amino acids in the binding site of complex dihydrofolate reductase with nicotinamide adenine dinucleotide phosphate.

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
Background: Given the benzimidazole derivatives have anti-ovarian cancer effects, the authors aimed to determine whether benzimidazole-2-substituted pyridine and phenyl propenone derivatives exert anti-ovarian cancer activity. Materials & methods: 21 derivatives were synthesized and assayed for their antiproliferative activities. Western blotting in A2780 cells was used to detect the effects of compound A-6 on apoptosis-related proteins. Invasion, migration and apoptosis were assayed in SKOV3 cells treated with A-6. The in vivo activity was also examined. Results: A-6 could inhibit proliferation, invasion and migration and induce apoptosis in SKOV3 cells. Additionally, A-6 had potent inhibitory activity in a xenograft mouse model. Conclusion: A-6 shows potent efficacy in the treatment of ovarian cancer and may be a potential antitumor agent.

Abstract
Naphthamide is a common structural framework with diverse pharmacological activities. Ten novel 2-naphthamide derivatives have been designed, synthesized, and evaluated for their in vitro antibacterial, antifungal, and anticancer activities. The title compounds were synthesized from dimethoxybenzaldehyde derivatives through a four-step microwave-assisted synthesis process. The structures were confirmed by 1H NMR, 13C NMR, and MS spectra. Compound 8b showed good antibacterial activity against Escherichia coli, Streptococcus faecalis, Salmonella enterica, MSSA, and MRSA with MIC values of 16, 16, 16, 8, and 16 μg/mL, respectively, compared to ciprofloxacin (MIC = 8-16 μg/mL). Compounds 5b (IC50 = 3.59-8.38 μM) and 8b (IC50 = 2.97-7.12 μM) exhibited good cytotoxic activity against C26, HepG2, and MCF7 cancer cell lines as compared to paclitaxel (IC50 = 2.85-5.75 μM). Moreover, compounds 5b and 8b exhibited better anticancer activity than PTX against the C26 cell line. In particular, compound 8b showed potent in vitro VEGFR-2 inhibitory activity with the IC50 value of 0.384 μM compared with sorafenib (IC50 = 0.069 μM). Therefore, compound 8b is the most potent compound for anticancer activity as indicated by in vitro cell line inhibition, in silico ADMET, molecular docking, and in vitro VEGFR-2 inhibition studies.
