Synthesis and anticancer activity evaluation of naphthalene-substituted triazole spirodienones.

ABSTRACT: Building on our previous work that discovered 1,2,4-triazole-spirodienone as a promising pharmacophore for anticancer activity, we have further diversified 1,2,4-triazole- spirodienone derivatives and synthesized a series of novel naphthalene-substituted triazole spirodienones to explore their antineoplastic activity. Of these, compound 6a possesses remarkable in vitro cytotoxic activity by arresting cell cycle and inducing apoptosis in MDA-MB-231 cells. Subsequently, acute toxicity assay showed that 6a at 20 mg/kg has no apparent toxicity to the major organ in mice. In addition, compound 6ain vivo suppressed breast cancer 4T1 tumor growth. Taken together, these results indicate that compound 6a may be a potential anticancer agent for further development.

New triazole-substituted triterpene derivatives exhibiting anti-RSV activity: synthesis, biological evaluation, and molecular modeling.

Project description:Respiratory syncytial virus (RSV) is a major cause of acute lower respiratory tract infections in infants. Currently, ribavirin, a nucleoside analog containing a 1,2,4-triazole-3-carboxamide moiety, is a first-line drug for its treatment, however, its clinical use has been limited due to its side effects. Here, we designed two new nitroaryl-1,2,3-triazole triterpene derivatives as novel anti-RSV drugs. Their anti-RSV and cytotoxic activity were evaluated in vitro, RSV protein F gene effects by RT-PCR and molecular modeling with inosine monophosphate dehydrogenase (IMPDH) were performed. Compound 8 was the best performing compound, with an EC50 value of 0.053 μM, a TI of 11160.37 and it inhibited hRSV protein F gene expression by approximately 65%. Molecular docking showed a top-ranked solution located in the same region occupied by crystallographic ligands in their complex with IMPDH. The results obtained in this study suggest that compound 8 might be a new anti-RSV candidate.

Synthesis of Triazole-Substituted Quinazoline Hybrids for Anticancer Activity and a Lead Compound as the EGFR Blocker and ROS Inducer Agent.

Project description:A series of triazole-substituted quinazoline hybrid compounds were designed and synthesized for anticancer activity targeting epidermal growth factor receptor (EGFR) tyrosine kinase. Most of the compounds showed moderate to good antiproliferative activity against four cancer cell lines (HepG2, HCT116, MCF-7, and PC-3). Compound 5b showed good antiproliferative activity (IC50 = 20.71 μM) against MCF-7 cell lines. Molecular docking results showed that compound 5b formed hydrogen bond with Met 769 and Lys 721 and π-sulfur interaction with Met 742 of EGFR tyrosine kinase (PDB ID: 1M17). Compound 5b decreases the expression of EGFR and p-EGFR. It also induces apoptosis through reactive oxygen species generation, followed by the change in mitochondrial membrane potential.

Design, synthesis and evaluation of novel 1,2,4-triazole derivatives as promising anticancer agents.

Project description:Herein, we reported the synthesis of nineteen novel 1,2,4-triazole derivatives including 1,3-diphenyl-2-(1H-1,2,4-triazol-1-yl) propan-1-ones (7a-e), 1-(1,3-diphenylpropan-2-yl)-1H-1,2,4-triazole (8a-c) and 1,4-diphenyl-2-(1H-1,2,4-triazol-1-yl) butane-1,4-diones (10a-k). The structures of these derivatives were confirmed by spectroscopic techniques like IR, 1H-NMR, Mass spectroscopy and Elemental analysis. The cytotoxic activities of the synthesized compounds were evaluated against three human cancer cell lines including MCF-7, Hela and A549 using MTT assay. Compounds 7d, 7e, 10a and 10d showed a promising cytotoxic activity lower than 12 μM against Hela cell line. The safety of these compounds was also, evaluated on MRC-5 as a normal cell line and relieved that most of the synthesized compounds have proper selectivity against normal and cytotoxic cancerous cell lines. Finally, molecular docking studies were also, done to understand the mechanism and binding modes of these derivatives in the binding pocket of aromatase enzyme as a possible target.

Discovery of 4-substituted methoxybenzoyl-aryl-thiazole as novel anticancer agents: synthesis, biological evaluation, and structure-activity relationships.

Project description:A series of 4-substituted methoxybenzoyl-aryl-thiazoles (SMART) have been discovered and synthesized as a result of structural modifications of the lead compound 2-arylthiazolidine-4-carboxylic acid amides (ATCAA). The antiproliferative activity of the SMART agents against melanoma and prostate cancer cells was improved from muM to low nM range compared with the ATCAA series. The structure-activity relationship was discussed from modifications of "A", "B", and "C" rings and the linker. Preliminary mechanism of action studies indicated that these compounds exert their anticancer activity through inhibition of tubulin polymerization.

Design, synthesis and pharmacological evaluation of 1,4-naphthoquinone- 1,2,3-triazole hybrids as new anticancer agents with multi-kinase inhibitory activity.

Project description:Targeting important oncogenic kinases that contribute to hallmarks of cancer has revolutionized cancer therapy. Ten 1,4-naphthoquinone derivatives linked to 1,2,3-triazole (4a-4j) were designed and synthesized as kinase inhibitors especially aimed at blocking CDK2, a validated and important cancer target. Assessment of the antiproliferative activity of the synthesized compounds against lung (EBC-1), pancreatic ductal adenocarcinoma (PDAC, AsPC-1 and Mia-Paca-2), colorectal (HT-29), and breast cancer (MCF-7) cells revealed that most of the derivatives possess considerable antiproliferative potential, with IC50 values as low as 0.3 µM. In contrast, the compounds relatively spared NIH3T3 non-cancer cell line. The kinase inhibitory effect of the best compounds was examined against a panel of 30 important oncogenic kinases. Derivatives 4a (bearing a benzyl ring) and 4i (bearing a p-methyl benzyl ring) inhibited CDK2, FLT4 (VEGFR3) and PDGFRA kinases with IC50 values in the range of 0.55-1.67 and 0.22-11.32 µM, respectively. These compounds also caused S phase arrest and induced characteristic features of apoptosis in PDAC cells. Molecular modeling simulation validated the binding interactions between the synthesized derivatives and the active sites of the 3 target kinases. Finally, the compounds also possessed drug-like features as examined by in silico studies. The results of this study indicate that 1,4-naphthoquinone derivatives could have promising anticancer potential as multi-kinase inhibitors.

Project description:A novel series of substituted 2-thiohydantoin incorporated with benzoimidazole, pyrazole, triazole and/or benzoxazole moieties has been synthesized using (E)-3-[1-(4-bromophenyl)ethylideneamino]-2-thioxoimidazolidin-4-one 1 as the key starting material. The key material 1 also, reacted with an acetic anhydride, aromatic aldehydes, secondary amines, formaldehyde and triethyl orthoformate to give the corresponding acetyl, chalcone, Mannich bases and ethoxymethylene derivatives, respectively. The structures of the novel compounds were confirmed by spectral data and elemental analysis. The cytotoxic activity of all synthesized compounds was assessed in vitro against human hepatocellular cancer cell line (HePG-2) and breast carcinoma cell line (MCF-7). The bioassay results revealed that compound 14 has the best activity against HePG-2 cell line (IC50 = 2.33 μg/mL), while compound 5 has the best activity against MCF-7 cell line (IC50 = 3.98 μg/mL).

New CD1d agonists: synthesis and biological activity of 6″-triazole-substituted α-galactosyl ceramides.

Project description:Huisgen [3+2] dipolar cycloaddition of 6″-azido-6″-deoxy-α-galactosyl ceramide 11 with a range of alkynes (or a benzyne precursor) yielded a series of triazole-containing α-galactosyl ceramide (α-GalCer) analogues in high yield. These α-GalCer analogues and the precursor azide 11 were tested for their ability to activate iNKT cells and stimulate IL-2 cytokine secretion in vitro, and IFN-γ and IL-4 cytokine secretion in vivo. Some of these analogues, specifically 11, 12b, 12f and 13, were more potent IL-2 stimulators than the prototypical CD1d agonist, α-GalCer 1. In terms of any cytokine bias, most of the triazole-containing analogues exhibited a small Th2 cytokine-biasing response relative to that shown by α-GalCer 1. In contrast, the cycloaddition precursor, namely azide 11, provided a small Th1 cytokine-biasing response.

Synthesis, spectroscopic characterization, and anticancer activity of new 10-substituted 1,6-diazaphenothiazines.

Project description:New phenothiazine derivatives as 10-substituted dipyridothiazines of the 1,6-diazaphenothiazine structure were obtained in the cyclization reaction of 3-amino-3'-nitro-2,2'-dipyridinyl sulfide and 3,3'-dinitro-2,2'-dipyridinyl disulfide, and in the reaction of 2-chloro-3-ntropyridine with sodium 3-amino-2-pyridinethiolate followed by various alkylation and arylation reactions. The reaction of the thiazine ring formation ran via the Smiles rearrangement of the S-N type. As the alkylation reactions could proceed at the thiazine, azine or both nitrogen atoms, the product structure elucidation was based on the 2D NMR (Rotating-frame Overhauser Effect Spectroscopy, Correlated Spectroscopy, Heteronuclear Single Quantum Coherence, and Heteronuclear Multiple Bond Correlation) spectra of the N-methylated product. Some 10-substituted 1,6-diazaphenothizines (5, 10, 12, 13) were at least anticancer active against melanoma C-32 and breast cancer MCF-7 cell lines as a reference drug - cisplatin. The monoazaphenothiazine drug, prothipendyl, turned out to be less active than least 6 derivatives of the 1,6-diazaphenothiazine structure.
