Efficient Electrosynthesis of Thiazolidin-2-imines via Oxysulfurization of Thiourea-Tethered Terminal Alkenes Using the Flow Microreactor

Sulfur-containing scaffolds play a significant role in many important biological processes. The thiazole-2-imine derivatives have gained significant biological attention due to their interesting pharmacological activities and act as potential therapeutic agents. Many of their syntheses suffer from the drawbacks such as the handling of toxic reagents, harsh reaction conditions, longer reaction times and tedious separation procedures. To their easy access, we applied first time flow electrochemical approach under free supporting electrolytes conditions and without the use of expensive catalysts and reagents. This is not only the first electrochemical cyclization to access thiazolidin-2-imines also represents the first intramolecular sulfurization of unfunctionalized terminal alkenes. This flow electrolysis of N-allylic thioureas generates radical intermediates of nitrogen and sulfur that cyclized via oxysulfurization of terminal alkenes and gives thiazolidin-2-imines with good to high yields under mild, green and environmentally friendly conditions.

Ovicidal in vitro activity of 2-aryl-3-(2-morpholinoethyl)thiazolidin-4-ones and 2-aryl-3-(3-morpholinopropyl)thiazolidin-4-ones against Fasciola hepatica (Linnaeus, 1758)

Although there is a variety of biological activity reports regarding compounds derived from thiazolidin-4-ones, no data related to ovicidal activity against trematodes, particularly Fasciola hepatica are available. Since there are reports about anthelmintic resistance in F. hepatica, new drugs are required. Thus, this study evaluated ovicidal action in vitro against F. hepatica eggs in two systematic series of thiazolidin-4-ones: 2-aryl-3-(2-morpholinoethyl)thiazolidin-4-ones (la-h) and 2-aryl-3-(3-morpholinopropyl)thiazolidin-4-ones (2a-h) at different concentrations (20, 2, 0.2, 0.02 and 0.002 mu g/ml). The egg hatch assay (EHA) was used to evaluate the ovicidal action property of such compounds. In addition, potential negative effects of the compounds on metabolic activity of bovine kidney (MDBK) cells were evaluated by determining mitochondrial dehydrogenase activity. The eggs used in the EHA were obtained from parasites removed from the liver of cattle, which were discarded by slaugh after sanitary inspection. The results of EHA showed that compounds 2a-h exhibited ovicidal activity, especially compounds 2b which showed 90% ovicidal activity and viability of 93% MDBK cells at the concentration of 2 mu g/ml; and 2e with 96-99% ovicidal activity at 0.2 mu g/ml, 0.02 mu g/ml and 0.002 mu g/ml. The results show the potential of compound 2b to continue the studies in the production of new compounds with anthelmintic action.

Synthesis and anticancer evaluation of novel isoxazole/pyrazole derivatives

The key intermediate 3-amino-5-methylisoxazole (1) was allowed to react with phthalic anhydride and/or maleic anhydride under different conditions to produce different isoxazole products. Schiff bases 9a-c obtained via the reaction of 1 with different aldehydes were condensed with thioglycolic acid to afford the corresponding thiazolidin-4-one derivatives 10a, b. Furthermore, condensation of the Schiff bases 9a, c with various secondary amines produced the corresponding 5-substituted pyrazole derivatives 11a-d, respectively. The anticancer activity of some of the newly synthesized compounds was evaluated against Panc-1 and Caco-2 cell lines using doxorubicin as a standard drug. Most of the tested derivatives exhibited high cytotoxic potency against Panc-1 carcinoma cell lines, but moderate to weak activity was obtained against Caco-2 cell lines.

1H-Tetrazol-5-amine and 1,3-thiazolidin-4-one derivatives containing 3-(trifluoromethyl) phenyl scaffold: Synthesis, cytotoxic and anti-HIV studies

On the basis of recently reported biologically active 3-(trifluoromethyl) phenylthioureas, a series of diaryl derivatives incorporating 1H-tetrazol-5-yl (1a-11a, 1a’-11a’) and 1,3-thiazolidin-4-one (1b-11b) scaffolds were synthesized. The synthesis pathway was confirmed by an X-ray crystallographic studies of 3a’, 6a, 8a, 6b and 8b. The cytotoxicity against MT-4 cells and anti-HIV properties of new derivatives were evaluated. As compared to initial thiourea connections, the cyclisation reduced the cytotoxicity of compounds by 2-15 times. The most promising N-(4-nitrophenyl)-1H-tetrazol-5-amine 7a was found to be more active than the origin thiourea. Its cytotoxicity was evaluated on A549, HTB-140 and HaCaT cell lines using MTT assay. The compound shows significant influence on cancer, but not on normal cells. Obtained results can provide some constructive data for further designing of novel family of potentially bioactive analogs. (c) 2017 Elsevier Masson SAS. All rights reserved.

A novel diacylglycerol kinase alpha-selective inhibitor, CU-3, induces cancer cell apoptosis and enhances immune response

Diacylglycerol kinase (DGK) consists of 10 isozymes. The alpha-isozyme enhances the proliferation of cancer cells. However, DGK alpha facilitates the nonresponsive state of immunity known as T-cell anergy; therefore, DGK alpha enhances malignant traits and suppresses immune surveillance. The aim of this study was to identify a novel small molecule that selectively and potently inhibits DGK alpha activity. We screened a library containing 9,600 chemical compounds using a newly established high-throughput DGK assay. As a result, we have obtained a promising compound, 5-[(2E)-3-(2-furyl)prop-2-enylidene]-3-[(phenylsulfonyl) amino]2-thioxo-1,3-thiazolidin-4-one) (CU-3), which selectively inhibited DGK alpha with an IC50 value of 0.6 mu M. CU-3 targeted the catalytic region, but not the regulatory region, of DGK alpha. CU-3 competitively reduced the affinity of DGK alpha for ATP, but not diacylglycerol or phosphatidylserine. Moreover, this compound induced apoptosis in HepG2 hepatocellular carcinoma and HeLa cervical cancer cells while simultaneously enhancing the interleukin-2 production of Jurkat T cells. Taken together, these results indicate that CU-3 is a selective and potent inhibitor for DGK alpha and can be an ideal anticancer drug candidate that attenuates cancer cell proliferation and simultaneously enhances immune responses including anticancer immunity.

Synthesis of novel inhibitors of alpha-amylase based on the thiazolidine-4-one skeleton containing a pyrazole moiety and their configurational studies

Postprandial hyperglycemia can be controlled by delaying the absorption of glucose resulting from carbohydrate digestion. alpha-Amylase is the initiator of the hydrolysis of polysaccharides, and therefore developing alpha-amylase inhibitors can lead to development of new treatments for metabolic disorders like diabetes mellitus. In the present work, we set out to rationally develop alpha-amylase inhibitors based on the thiazolidine-4-one scaffold. The structures of all these newly synthesized hybrids were confirmed by spectroscopic analysis (IR, H-1-NMR, MS). The appearance of two sets of signals for some protons in H-1 NMR revealed the existence of a mixture of 2E, 5Z (37.1-42.0%) and 2Z, 5Z isomers (58.4-62.8%), which was further supported by DFT studies. All the newly synthesized compounds have potential inhibitory properties as revealed through in vitro alpha-amylase inhibition activity. Compound 5a at 100 mu g mL(-1) concentration showed a remarkable inhibition of 90.04%. In vitro alpha-amylase inhibition was further supported by docking studies of compound 5a against the active site of human pancreatic alpha-amylase (PDB ID: 2QV4). The docking studies revealed that the bonding interactions found between 5a and human pancreatic alpha-amylase are similar to those responsible for alpha-amylase inhibition by acarbose.
