In this study, 22 novel compounds were designed and synthesized by acetamide bridge chains, among which 5 a–5 k were monosubstituted compounds, and 6 a–6 k were disubstituted. A series of biological evaluations was then carried out to determine the carbonic anhydrase inhibitory activity, neuroprotective effects and cytotoxicity of 5 a–5 k and 6 a–6 k. The results showed that some compounds could protect PC12 cells from sodium nitroprusside (SNP)-induced damage. In terms of the neuroprotection and inhibitory activity against carbonic anhydrase II, monosubstituted compounds were better than disubstituted. Compound 5 c exhibited better protective effect in PC12 cells than that of edaravone, and 5 c also showed less cytotoxicity. In addition, compound 5 c was found to be the most effective selective carbonic anhydrase II inhibitor (IC50=16.7 nM, CAI/CAII=54.3), which was similar to the inhibitory effect of acetazolamide. Moreover, the selectivity of compound 5 c was better than that of acetazolamide (IC50=12.0 nM, CAI/CAII=20.8). Molecular docking presented that the binding effect of compound 5 c with carbonic anhydrase II was superior to that of 5 c with carbonic anhydrase I and IX, which was consistent with the inhibitory results. Based on above findings, compound 5 c may be a potential candidate for selective carbonic anhydrase II inhibitor, and it had obviously neuroprotective effect and great advantages in drug safety.

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.].

Twenty new 12N-substituted matrinol derivatives were synthesized and evaluated for their inhibitory effects on collagen α1 (I) (COL1A1) promotor in human hepatic stellate LX-2 cells. The structure-activity relationship (SAR) revealed that introducing a 12N-benzeneaminoacylmethyl substitution might significantly enhance the activity. Compound 8a exhibited the highest inhibitory potency against COL1A1, and its inhibition activity against COL1A1 was further confirmed on both the mRNA and protein levels. It also effectively inhibited the expression of α smooth muscle actin (α-SMA), fibronectin and transforming growth factor β1 (TGFβ1), indicating an extensive inhibitory effect on the expression of fibrogenic genes. The primary mechanism study indicated that it might take action via the Integrin/FAK/PI3K/Akt signaling pathway. The results provided powerful information for further structure optimization, and compound 8a was selected as a novel anti-fibrogenic lead for further investigation.

A novel series of acetamide-substituted derivatives and two prodrugs of doravirine were designed and synthesized as potent HIV-1 NNRTIs by employing the structure-based drug design strategy. In MT-4 cell-based assays using the MTT method, it was found that most of the new compounds exhibited moderate to excellent inhibitory potency against the wild-type (WT) HIV-1 strain with a minimum EC50 value of 54.8 nM. Among them, the two most potent compounds 8i (EC50 = 59.5 nM) and 8k (EC50 = 54.8 nM) displayed robust activity against WT HIV-1 with double-digit nanomolar EC50 values, being superior to lamivudine (3TC, EC50 = 12.8 μM) and comparable to doravirine (EC50 = 13 nM). Besides, 8i and 8k shown moderate activity against the double RT mutant (K103N + Y181C) HIV-1 RES056 strain. The HIV-1 RT inhibition assay further validated the binding target. Molecular simulation of the representative compounds was employed to provide insight on their structure-activity relationships (SARs) and direct future design efforts. Finally, the aqueous solubility and chemical stability of the prodrugs 9 and 10 were investigated in detail.

A series of novel 1,2,4-triazole derivatives (7a-7p) containing the quinazolinylpiperidinyl moiety and N-(substituted phenyl)acetamide group were designed, synthesized and evaluated for their antimicrobial activities in vitro. These compounds were fully characterized by 1H NMR, 13C NMR, HRMS and IR spectra. Notably, the structure of compound 7p was further confirmed through the single-crystal X-ray diffraction method. The obtained bioassay results indicated that most of these compounds exhibited good to excellent antibacterial activities against the rice bacterial pathogen Xanthomonas oryzae pv. oryzae (Xoo). For example, compounds 7e, 7g, 7n, 7l, 7i, 7k, 7a and 7h had EC50 (half-maximal effective concentration) values of 34.5, 38.3, 39.0, 46.0, 47.5, 54.6, 55.0 and 58.2 μg mL-1 against the bacterium, respectively, which were significantly lower than the control agent Bismerthiazol (85.6 μg mL-1). Additionally, antifungal experiments demonstrated that all the compounds did possess weak inhibition capabilities against three phytopathogenic fungi at 50 μg mL-1, except in the cases of compounds 7e and 7p against the fungus Gibberella zeae. The above experimental results proved that 1,2,4-triazole derivatives bearing both a quinazolinylpiperidinyl fragment and N-(substituted phenyl)acetamide unit are promising candidates for the development of new agricultural bactericides against the pathogenic bacterium Xoo, deserving further investigation in the future.

Small molecules that bind to RNA potently and specifically are relatively rare. The study of molecules that bind to the HIV-1 transactivation response (TAR) hairpin, a cis-acting HIV genomic element, has long been an important model system for the chemist

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.
