New potent antifungal triazole alcohols containing N-benzylpiperazine carbodithioate moiety: Synthesis, in vitro evaluation and in silico study

A number of 1H-1,2,4-triazole alcohols containing N-(halobenzyl)piperazine carbodithioate moiety have been designed and synthesized as potent antifungal agents. In vitro bioassays against different Candida species including C. albicans, C. glabrata, C. parapsilosis, C. krusei, and C. tropicalis revealed that the N-(4-chlorobenzyl) derivative (6b) with MIC values of 0.063–0.5 μg/mL had the best profile of activity, being 4–32 times more potent than fluconazole. Docking simulation studies confirmed the better fitting of compound 6b in the active site of lanosterol 14α-demethylase (CYP51) enzyme, the main target of azole antifungals. Particularly, the potential of compound 6b against fluconazole-resistant isolates along with its minimal toxicity against human erythrocytes and HepG2 cells make this prototype compound as a good lead for discovery of potent and safe antifungal agents.

Design, synthesis and evaluation against Mycobacterium tuberculosis of azole piperazine derivatives as dicyclotyrosine (cYY) mimics

Three series of azole piperazine derivatives that mimic dicyclotyrosine (cYY), the natural substrate of the essential Mycobacterium tuberculosis cytochrome P450 CYP121A1, were prepared and evaluated for binding affinity and inhibitory activity (MIC) against M. tuberculosis. Series A replaces one phenol group of cYY with a C3-imidazole moiety, series B includes a keto group on the hydrocarbon chain preceding the series A imidazole, whilst series C explores replacing the keto group of the piperidone ring of cYY with a CH2-imidazole or CH2-triazole moiety to enhance binding interaction with the heme of CYP121A1. The series displayed moderate to weak type II binding affinity for CYP121A1, with the exception of series B 10a, which displayed mixed type I binding. Of the three series, series C imidazole derivatives showed the best, although modest, inhibitory activity against M. tuberculosis (17d MIC = 12.5 μg/mL, 17a 50 μg/mL). Crystal structures were determined for CYP121A1 bound to series A compounds 6a and 6b that show the imidazole groups positioned directly above the haem iron with binding between the haem iron and imidazole nitrogen of both compounds at a distance of 2.2 ?. A model generated from a 1.5 ? crystal structure of CYP121A1 in complex with compound 10a showed different binding modes in agreement with the heterogeneous binding observed. Although the crystal structures of 6a and 6b would indicate binding with CYP121A1, the binding assays themselves did not allow confirmation of CYP121A1 as the target.

A series of novel 1,2,4-triazole thione and bis(1,2,4-triazole thione) derivatives containing phenylpyrazole and substituted piperazine moieties have been conveniently synthesized via Mannich reaction using various 1,2,4-triazole thiols, substituted piperazines, and formaldehyde at room temperature in short time. Their structures were confirmed by IR, 1H NMR, 13C NMR and elemental analysis. The preliminary bioassays for 27 new title compounds have shown that some of them possess certain herbicidal activities against Echinochloa crusgalli at 100 μg/mL concentration. Some of the compounds exhibited significant in vitro fungicidal activities, especially against Cercospora arachidicola and Rhizoctonia cerealis at the concentration of 50 μg/mL, and were comparable with that of control Triadimefon. Meanwhile, IXp held the control efficacy of 60% against Puccinia sorghi Schw. at 200 μg/mL concentration in the in vivo test. The SAR analysis has indicated that compounds with two CF3 groups both on triazole and pyrazole rings are more effective than compounds with one CF3 group or two CH3 groups according to their fungicidal activity data. On the whole, compounds VIIIg, IXi, IXo and IXp could be used as novel lead structures for the design and discovery of new fungicides.

Among 24 novel compounds, some showed superiority over the commercial fungicides Chlorothalonil, Dimethomorph, Thiophanate-methyl, Iprodione, and Zhongshengmycin at 500 mg/L concentration. Some compounds also exhibited high KARI inhibitory activity at 100 γ1/4g/mL concentration and could be used as new KARI lead inhibitors for further studies. Moreover, SAR of these new compounds were comprehensively investigated using different computational methods in which 3D-QSAR model obtained provided useful information for further structural optimization for the discovery of new fungicides. The results of this research will contribute to explore comprehensive biological activities of piperazine-containing compounds in different areas of chemistry.

Their structures were characterized by melting points, 1H NMR, 13C NMR, IR and elemental analysis. The preliminary bioassay showed that most compounds exhibited significant in vitro and in vivo fungicidal activity against several test plant fungi. Among 32 new compounds, the trifluoromethyl-containing compounds showed superior activity than the methyl-containing ones. Several compounds, such as F8, F9, F10, G5, H7, H8, I3 and I4, were comparable with some commercial fungicides against different fungi during the present study and could be further structurally optimized. Meanwhile, several compounds showed good herbicidal activity against Brassica campestris at 100 μg/mL and KARI inhibitory activity at 200 μg/mL. However, compounds exhibited poor insecticidal activity against oriental armyworm at 200 μg/mL in the preliminary studies. The research results will provide useful information for the design and discovery of new agrochemicals with novel heterocyclic structures.

Synthesis and bioactive evaluations of novel benzotriazole compounds as potential antimicrobial agents and the interaction with calf thymus DNA

A novel series of benzotriazole derivatives were synthesized and characterized by NMR, IR and MS spectra. The bioactive assay manifested that most of the new compounds exhibited moderate to good antibacterial and antifungal activities against the tested strains in comparison to reference drugs chloromycin, norfloxacin and fluconazole. Especially, 2,4-dichlorophenyl substituted benzotriazole derivative 6f displayed good antibacterial activity against MRSA with MIC value of 4 μg/mL, which was 2-fold more potent than Chloromycin, and it also displayed 3-fold stronger antifungal activity (MIC = 4 μg/mL) than fluconazole (MIC = 16 μg/mL) against Beer yeast. The preliminary interactive investigations of compound 6f with calf thymus DNA revealed that compound 6f could effectively intercalate into DNA to form compound 6f-DNA complex which might block DNA replication to exert antimicrobial activities. Molecular docking experiments suggested that compound 6f projected into base-pairs of DNA hexamer duplex forming two hydrogen bonds with guanine of DNA. The theoretical calculations were in accordance with the experimental results.

Exploration of (S)-3-aminopyrrolidine as a potentially interesting scaffold for discovery of novel Abl and PI3K dual inhibitors

Based on the literature-reported compensatory effect of PI3K on Abl inhibition and the improved preclinical effect of drug combination of Abl and PI3K inhibitors, a series of compounds bearing novel scaffold of (S)-3-aminopyrrolidine was identified as Abl and PI3K dual inhibitors through support vector machine screening tool, which were subsequently synthesized and tested. Most compounds demonstrated promising cytoxicity against a CML leukemia cell-line K562 and moderate inhibition against Abl and PI3K kinases. These compounds induced no apoptosis in K562 cell-line, suggesting that their cytotoxic activities are unlikely duo to other known anti-CML mechanisms. Molecular docking study further showed that the compound 5k could bind with both Abl and PI3K, but the weaker binding with Abl compared to Imatinib is consistent with its low kinase inhibitory rates. These plus literature-reported evidences suggest that the promising cytotoxic effect of our novel compounds might be due to the collective effect of Abl and PI3K inhibition.
