A series of 1,2,3-triazole derivatives based on the quinoline–benzimidazole hybrid scaffold was designed, synthesized, and screened against a panel of NCI-60 humanoid cancer cell lines for in vitro cytotoxicity evaluation, which revealed that compound Q6 was the most potent cytotoxic agent with excellent GI50, TGI, and LC50 values on multiple cancer cell lines. Q6 was tested further on the BT-474 breast cancer line to evaluate the mechanism of action. Preliminary screening studies based on the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay revealed that compound Q6 had an excellent antiproliferative effect against human breast cancer cells, BT-474, with IC50 values of 0.59 ± 0.01 μM. The detailed study based on the acridine orange/ethidium bromide staining (AO/EB) and the 4′,6-diamidino-2-phenylindole (DAPI) assay suggested that the antiproliferative activity shown was due to the induction of apoptosis on exposure to Q6. Further, DCFDA staining showed the generation of reactive oxygen species, altering the mitochondrial potential and leading to the initiation of apoptosis. This was further supported by JC-1 staining, indicating that this scaffold can contribute to the development of more potent derivatives.

Some novel benzimidazole-tethered 1,2,3-triazole derivatives (4a–r) were synthesized by a click reaction between 2-substituted 1-(prop-2-yn-1-yl)-1H-benzo[d]imidazole and in situ azide. The structures of the synthesized compounds were confirmed by spectroscopic studies (one- and two-dimensional nuclear magnetic resonance, Fourier transform infrared, and high-resolution mass spectra). The synthesized compounds were evaluated for their antidiabetic activity. Compounds 4a–r exhibited a good-to-moderate α-amylase and α-glucosidase inhibitory activity, with IC50 values ranging from 0.0410 to 0.0916 μmol/ml and 0.0146 to 0.0732 μmol/ml, respectively. Compounds 4e, 4g, and 4n were found to be most active. Furthermore, the binding conformation of the most active compounds was ascertained by docking studies.

A series of novel 2-hydroxyphenyl substituted aminoacetamides was designed by molecular hybridization of the aminoacetamide scaffold and 2-hydroxyphenyl motif. The target compounds were synthesized and their fungicidal activities were evaluated. Some of the target compounds showed excellent antifungal activities against S. sclerotiorum and P. capsici. Significantly, compounds 5e displayed the most potent activity against S. sclerotiorum with EC50 = 2.89 μg/mL, which was lower than that of commercial chlorothalonil. The systematic studies provided strong confidence that the hydroxyl group and the carbonyl group are crucial for the fungicidal activity. Molecular docking studies suggest that SDH enzyme could be one of the potential action targets of our compounds.

Herein we describe the development of a focused series of functionalized pyridazin-3(2H)-one-based formyl peptide receptor (FPR) agonists that demonstrate high potency and biased agonism. The compounds described demonstrated biased activation of prosurvival signaling, ERK1/2 phosphorylation, through diminution of the detrimental FPR1/2-mediated intracellular calcium (Cai2+) mobilization. Compound 50 showed an EC50 of 0.083 μM for phosphorylation of ERK1/2 and an approximate 20-fold bias away from Cai2+ mobilization at the hFPR1.

Abstract: A total of eighteen 2-((2-(4-(1H-1,2,4-triazol-1-yl)phenyl)quinazolin-4-yl)oxy)-N-phenylacetamide derivatives were designed and synthesized, via hybrid pharmacophore approach. Among these compounds, chemical structure of compound 4a was unambiguously confirmed by means of single-crystal X-ray diffraction analysis. All the compounds were evaluated in vitro for their inhibition activity against several important phytopathogenic bacteria and fungi in agriculture. The obtained results indicated that several compounds demonstrated potent antibacterial activity against Xanthomonas oryzae pv. oryzae (Xoo). For example, compounds 4c, 4g and 4q had EC50 values of 35.0, 36.5 and 32.4 μg/mL toward this bacterium, respectively, around 1.5 times more active than commercial bactericide bismerthiazol (EC50 = 89.8 μg/mL). Additionally, compounds 4j and 4p were found to display comparable antifungal activity against Gloeosporium fructigenum at 50 μg/mL, to commercial fungicide hymexazol. Finally, the relationships between antibacterial activities and molecular structures of this class of compounds were discussed in detail. Graphical abstract: [Figure not available: see fulltext.].

3-Amino-2-arylcarboxamide-thieno[2,3-b]pyridines are a known class of antiproliferative compounds with activity against the phospholipase C enzyme. To further investigate the structure activity relationships of these derivatives a series of analogues were prepared modifying key functional groups. It was determined that modification of the 3-amino and 2-aryl carboxamide functionalities resulted in complete elimination of activity, whilst modification at C-5 allowed compounds of greater activity to be prepared.

2-(Quinolin-4-yloxy)acetamides have been described as potent in vitro inhibitors of Mycobacterium tuberculosis growth. Herein, additional chemical modifications of lead compounds were carried out, yielding highly potent antitubercular agents with minimum inhibitory concentration (MIC) values as low as 0.05 μM. Further, the synthesized compounds were active against drug-resistant strains and were devoid of apparent toxicity to Vero and HaCat cells (IC50s ≥ 20 μM). In addition, the 2-(quinolin-4-yloxy)acetamides showed intracellular activity against the bacilli in infected macrophages with action similar to rifampin, low risk of drug-drug interactions, and no sign of cardiac toxicity in zebrafish (Danio rerio) at 1 and 5 μM. Therefore, these data indicate that this class of compounds may furnish candidates for future development to, hopefully, provide drug alternatives for tuberculosis treatment.
