Chemotherapy is the most common clinical treatment for non-small cell lung cancer (NSCLC), but low efficiency and high toxicity of current chemotherapy drugs limit their clinical application. Therefore, it is urgent to develop hypotoxic and efficient chemotherapy drugs. Theophylline, a natural compound, is safe and easy to get, and it can be used as a modified scaffold structure and hold huge potential for developing safe and efficient antitumor drugs. Herein, we linked theophylline with different azide compounds to synthesize a new type of 1,2,3-triazole ring-containing theophylline derivatives. We found that some theophylline1,2,3-triazole compounds showed a good tumor-suppressive efficacy. Especially, derivative d17 showed strong antiproliferative activity against a variety of cancer cells in vitro, including H460, A549, A2780, LOVO, MB-231, MCF-7, OVCAR3, SW480, and PC-9. It is worth noting that the two NSCLC cell lines H460 H and A549 are sensitive to compound d17 particularly, with IC50 of 5.929 ± 0.97?μM and 6.76 ± 0.25?μM, respectively. Compound d17 can significantly induce cell apoptosis by increasing the ratio of apoptotic protein Bax/Bcl-2 by downregulating the expression of phosphorylated Akt protein, and it has little toxicity to normal hepatocyte cells LO2 at therapeutic concentrations. These data indicate that these theophylline acetic acid-1,2,3-triazole derivatives may be potential drug candidates for anti-NSCLC and are worthy of further study.

The reaction of organic azides and electron-deficient alkenes was investigated in a deep eutectic solvents. A series of highly substituted 2-pyrazolines was successfully isolated and their formation rationalised by DFT calculations. The critical effect of substitution was also explored; even relatively small changes in the cycloaddition partners led to completely different reaction outcomes and triazolines, triazoles or enaminones can be formed as major products depending on the alkene employed.

A series of fluorinated analogs based on the frameworks of 4-(1-phenyl-1H-[1,2,3]triazol-4-yl)-phenyl sulfamates have been synthesized as steroid sulfatase (STS) inhibitors. The design of chemical structures of new potential STS inhibitors was supported by molecular docking techniques to identify potential interactions between inhibitors and amino acid residues located in the STS active site. The STS inhibitory potency was evaluated on STS isolated from human placenta. We found that compounds substituted with fluorine atom at the meta position demonstrated the highest inhibitory effects in enzymatic STS assay. The most active analog 12e–inhibited STS enzyme with the IC50 value of 36 nM.

Gankyrin is an oncoprotein overexpressed in numerous cancer types and appears to play a key role in regulating cell proliferation, cell growth, and cell migration. These roles are largely due to gankyrin's protein-protein interaction with the 26S proteaso

In the present study a library of thiophenol-formaldehyde-triazole (TFT) derivatives was synthesized and screened against CAOV3, CAOV4 and ES-2 ovary cancer cell lines. Initial screening revealed that five-compounds 5a, 5b, 5j, 5h and 5i inhibited the viability of tested cell lines. Analysis of apoptosis revealed that increase in compound 5a (most active) concentration from 0.25 to 2.0 μM enhanced apoptotic cell proportion. Transwell assay showed reduction in invasive potential of CAOV3 cells on treatment with compound 5a. In wound healing assay increasing the concentration of compound 5a from 0.5 to 2.0 μM caused a significant (P 0.05) decrease in the migration potential. Western blotting showed that compound 5a treatment markedly decreased the level of matrix metalloproteinase (MMP)-2 and ?9 in CAOV3 cells. Treatment of CAOV3 cells with compound 5a caused a marked decrease in Focal Adhesion Kinase (FAK) activation. Tumor growth was inhibited in the compound 5a treated mice markedly than those of untreated group. The tumor metastasis to liver, intestine, spleen and peritoneal cavity was markedly decreased in mice treated with 10 mg/kg dose of compound 5a. Examination of Von Willebrand factor (vWF) expression in liver, intestinal and pulmonary lesions showed a marked decrease in the compound 5a-treated mice. The infiltration of macrophages in the metastatic lesions showed a significant decrease in compound 5a-treated mice. In conclusion, the compound 5a inhibited ovary cancer cell viability and induced apoptosis through decrease in expression of vWF and metalloproteinase, suppression of FAK activation and decrease in infiltration of macrophages. The compound 5a therefore can be investigated further for the treatment of ovary cancer.

Reported herein is the design, synthesis, and pharmacologic evaluation of a class of TRPV1 antagonists constructed on 2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole as A-region and triazole as B-region. The SAR analysis indicated that 2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole analogues displayed excellent antagonism of hTRPV1 activation by capsaicin and showed better potency compared to the corresponding dihydroindole analogues. Optimization of this design led to the eventual identification of 2-((1-(2-(trifluoromethyl)phenyl)-1H-1,2,3-triazol-4-yl)methyl)-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole (6g), a potent TRPV1 antagonist. In vitro, using cells expressing recombinant human TRPV1 channels, 6g displayed potent antagonism activated by capsaicin (IC50 = 0.075 μM) and only partially blocked acid activation of TRPV1. In vivo, 6g exhibited good efficacy in capsaicin-induced and heat-induced pain models and had almost no hyperthermia side-effect. Furthermore, pharmacokinetic studies revealed that compound 6g had a superior oral exposure after oral administration in rats. To understand its binding interactions with the receptor, the docking study of 6g was performed in rTRPV1 model and showed an excellent fit to the binding site. On the basis of its superior profiles, 6g could be considered as the lead candidate for the further development of antinociceptive drugs.

Amyloid beta (Aβ) peptide aggregation is considered as one of the key hallmarks of Alzheimer's disease (AD). Moreover, Aβ peptide aggregation increases considerably in the presence of metal ions and triggers the generation of reactive oxygen species (ROS)

A convenient CuI/DBU catalyzed one-pot method has been developed for the synthesis of 1,4-disubstituted 1,2,3-triazoles through the coupling of aryl iodides with sodium azide, followed by the intermolecular cyclization between the generated aryl azides and phenylacetaldehyde derivatives or alkynes in DMSO. The established protocol was compatible with a wide scope of substrates in good to excellent yields.
