Synthesis and biological evaluation of innovative thiourea derivatives as PHGDH inhibitors

In order to discover novel compounds with inhibitory activity against 3-phosphoglycerate dehydrogenase (PHGDH), a series of thiourea derivatives were designed and synthesized based on the structural modification of compound 5d. Compound 5d emerged from the visual database of ChemDiv of 200,000 small molecules by docking score ranking. Inhibition experiments on PHGDH activity of newly synthesized compounds were performed in vitro. Compounds with more than 30percent inhibitory rate at 25?μM on PHGDH were screened for IC50 measurement. Anti-proliferative activity of 4a, 5a, 6e, 6n against A2780, MDA-MB-468, MDA-MB-231 and HEK293T in vitro was evaluated. The results showed that the compound 4a displayed the best inhibitory activity on PHGDH among the newly synthesized compounds, and the compounds 4a, 5a, 6n had a better proliferation inhibition effect on human A2780 cell line than NCT-503 reported previously. In addition, 2D interaction diagrams revealed potential action modes of active compounds with PHGDH.

Synthesis and anti-endoplasmic reticulum stress activity of N-substituted-2-arylcarbonylhydrazinecarbothioamides

Misfolded or unfolded proteins are accumulated in lumen of endoplasmic reticulum (ER) in ER stress condition. It has been implicated in many pathological conditions such as Alzheimer’s disease, diabetic retinopathy, atherosclerosis, β-cell apoptosis and lung inflammation. We found a series of N-substituted-2-arylcarbonylhydrazinecarbothioamides to potently decrease ER stress signal, showing up to almost 300-fold better activity than 1-hydroxynaphthoic acid and tauro-ursodesoxycholic acid, positive controls, respectively. Structure?activity relationship (SAR) study showed that 2-arylcarbonyl moiety is critical for the activity of the hydrazinecarbothioamide analogues and side chains tethering on thioamide moiety were relatively insensitive to the activity. Some analogues were found to consistently exert the potency under more physiologically relevant condition where ER stress was induced by palmitic acid. ER stress markers such as CHOP and phosphorylated eIF2α and PERK were accordingly decreased in western blotting upon treatment of compound 4h. Potential ER stress inhibitory activity and novel structures could provide a novel platform for new chemical chaperone and therapy for protein misfolding diseases.

Na2S2O8-mediated efficient synthesis of isothiocyanates from primary amines in water

We have developed two green, practical, and efficient procedures, including a one-pot one, to synthesize isothiocyanates from amines and carbon disulfide via desulfurization with sodium persulfate. Water is used as the solvent. Basic conditions are necessary for good chemoselectivity for isothiocyanates. Structurally diverse linear and branched alkyl amines and aryl amines are readily converted to isothiocyanates by the two procedures in satisfactory yields. Halogens, benzylic C-H bonds, methylthio, nitro, ester, alkenyl, electron-rich or -deficient (hetero)aryls, acetylenyl, and even phenolic and alcoholic hydroxyls are well tolerated. The one-pot procedure in water can also be used to realize the preparation of chiral isothiocyanates from chiral amines, and the modification of bioactive structures with free amino groups. In large-scale preparation, simple and practical purification procedures independent of column chromatography are developed.

Pyrazolopyrimidines: Potent Inhibitors Targeting the Capsid of Rhino- and Enteroviruses

There are currently no drugs available for the treatment of enterovirus (EV)-induced acute and chronic diseases such as the common cold, meningitis, encephalitis, pneumonia, and myocarditis with or without consecutive dilated cardiomyopathy. Here, we report the discovery and characterization of pyrazolopyrimidines, a well-tolerated and potent class of novel EV inhibitors. The compounds inhibit the replication of a broad spectrum of EV in vitro with IC50 values between 0.04 and 0.64 μM for viruses resistant to pleconaril, a known capsid-binding inhibitor, without affecting cytochrome P450 enzyme activity. Using virological and genetics methods, the viral capsid was identified as the target of the most promising, orally bioavailable compound 3-(4-trifluoromethylphenyl)amino-6-phenylpyrazolo[3,4-d]pyrimidine-4-amine (OBR-5-340). Its prophylactic as well as therapeutic application was proved for coxsackievirus B3-induced chronic myocarditis in mice. The favorable pharmacokinetic, toxicological, and pharmacodynamics profile in mice renders OBR-5-340 a highly promising drug candidate, and the regulatory nonclinical program is ongoing. Curing the common cold! A cluster of pyrazolopyrimidines with potent broad-spectrum activity against enteroviruses was discovered. Extensive structure-property relationship analyses led to the identification of 3-(4-trifluoromethyl-phenyl)amino-6-phenylpyrazolo[3,4-d]pyrimidine-4-amine, shown to be a blocker of the viral capsid protein, as a lead compound for drug development with favorable physicochemical, pharmacokinetic, and toxicological properties.

Synthesis and biological evaluation of arylthiourea derivatives with antitubercular activity

Tuberculosis (TB) is a contagious disease caused by Mycobacterium tuberculosis (M. tuberculosis), and remains one of the most life-threatening plagues for public health in the world. The emergence of drug resistant strains of TB and co-infection with HIV has further complicated TB treatment. Here, the synthesis and characterizaton of a series of compounds were described, and these were followed by evaluating for their antibacterial activity against M. tuberculosis. Several novel arylthiourea derivatives exhibited excellent activity (lowest MIC=0.09 μg/ml) against M. tuberculosis including drug resistant strains of M. tuberculosis. The results suggest that these compounds are promising candidates for new anti-TB agent development.

The efficient synthesis of 4-substituted 5-thioxo-1,2,4-triazolidin-3-one derivatives (4-substituted thiourazoles) via domino combination of thiophosgene, aliphatic or aromatic amines, and ethyl carbazate is presented.

Synthesis and pesticidal properties of thio and seleno analogs of some common urea herbicides

Thio and seleno analogs of fenuron, isoproturon, chlorotoluron, metoxuron, monuron, and diuron were synthesized from the corresponding aryl amines. Their reaction with thiophosgene leads to isothiocyanates. Aryl amines were also converted (via isocyanides) to isoselenocyanates. The reaction of both isothio- and isoselenocyanates with dimethylamine affords the corresponding thio and seleno analogs of the above-mentioned urea herbicides. Herbicidal activity of the synthesized compounds was slightly lower than the activity of the parent urea herbicides. The thio and seleno analogs as well as the parent ureas showed good fungicidal activity at a concentration of 200 ppm against selected fungi.
