Regioselective synthesis of alpha-fluoro-beta-arylalkenyl sulfides has been established with gem-difluoroalkenes and sodium sulfinates in a transition-metal-free manner. A series of control experiments were executed to demonstrate thiol radicals and anions as the proposed intermediates. Notably, regioselective Z -> E isomerization was achieved under green light irradiation in the absence of a photoinitiator.

Carboxylesterase (CES) plays an important role in the hydrolysis metabolism of ester-type drugs and prodrugs. In this study, we investigated the change in the hydrolysis rate of hCE1 by focusing on the steric hindrance of the ester structure and the electron density. For 26 kinds of synthesized indomethacin prodrugs, the hydrolytic rate was measured in the presence of human liver microsomes (HLM), human small intestine microsomes (HIM), hCE1 and hCE2. The synthesized prodrugs were classified into three types: an alkyl ester type that is specifically metabolized by hCE1, a phenyl ester type that is more easily metabolized by hCE1 than by hCE2, and a carbonate ester type that is easily metabolized by both hCE1 and hCE2. The hydrolytic rate of 1-methylpentyl (hexan-2-yl) ester was 10-times lower than that of 4-methylpentyl ester in hCE1 solution. hCE2 was susceptible to electron density of the substrate, and there was a difference in the hydrolysis rate of up to 3.5-times between p-bromophenyl ester and p-acetylphenyl ester. By changing the steric hindrance and electron density of the alkoxy group, the factors that change the hydrolysis rate by CES were elucidated.

The Pot, Atom, and Step Economy (PASE) approach is based on the Pot economy principle and unites it with the Atom and Step Economy strategies; it ensures high efficiency, simplicity and low waste formation. The PASE approach is widely used in multicomponent chemistry. This approach was adopted for the synthesis of previously unknown hydroxyquinolinone substituted chromeno[2,3-b]pyridines via reaction of salicylaldehydes, malononitrile dimer and hydroxyquinolinone. It was shown that an ethanol-pyridine combination is more beneficial than other inorganic or organic catalysts. Quantum chemical studies showed that chromeno[2,3-b]pyridines has potential for corrosion inhibition. Real time H-1 NMR monitoring was used for the investigation of reaction mechanism and 2-((2H-chromen-3-yl)methylene)malononitrile was defined as a key intermediate in the reaction.

Three copper(I) complexes, [CuCl(L)(PPh3)(2)] [L = FL (1), BL (2) or TL (3)] were prepared from [(PPh3)(2)Cu(mu-Cl)(2)Cu(PPh3)] and N-carbamothioylfuran-2-carboxamide (FL), N-carbamothioylbenzamide (BL) or N-carbamothioylthiophene-2-carboxamide (TL) ligands in benzene and four-coordinated tetrahedral copper complexes were well characterized by various spectroscopic techniques (UV/Vis, FT-IR, H-1 NMR, C-13 NMR and P-31 NMR). The molecular structure of the ligands (FL and BL) and complexes was established from single-crystal X-ray diffraction studies. Copper complexes have been shown to catalyse the one-pot synthesis of imines and quinoxalines. Heterogenized catalyst (4) was prepared by reacting more active complex 3 with polystyrene supported triphenylphosphane, and characterized by elemental analyses, and DRS-UV, FT-IR, ICP-OES, and solid-state NMR techniques. Catalytic activity of the complexes (3 and 4) was tested in the formation of imines from alcohols and amines, and quinoxalines from hydroxy ketones and diamines. Heterogeneity and reusability of catalyst 4 were evaluated, and the catalyst can be reused for four runs without any loss in activity.

Fatty acid synthase (FASN) is a lipogenic enzyme that is selectively upregulated in malignant cells. There is growing consensus on the oncogenicity of FASN-driven lipogenesis and the potential of FASN as a druggable target in cancer. Here, we report the synthesis and FASN inhibitory activities of two novel galloyl esters of trans-stilbene EC1 and EC5. Inhibition of FASN was accompanied by a loss in AKT activation and profound apoptosis in several non-small cell lung cancer (NSCLC) cells at the growth inhibitory concentrations of EC1 and EC5. Both FASN and phospho-AKT levels were concurrently downregulated. However, addition of a lipid concentrate to the treated cells reinstated cell viability and reversed the loss of FASN and AKT protein levels, thus recapitulating the causal relationship between FASN inhibition and the loss in cell viability.

Induced by visible light, a green approach for the highly substituted trifluoromethyl olefins has been developed by using alkyl boronic acid as a carbon radical precursor and the Boc-modified trifluoromethylated Baylis-Hillman adduct (BMTBHA) as an acceptor. This method starts from 1,1-disubstituted olefins without the external stoichiometric oxidant. (C) 2021 Elsevier Ltd. All rights reserved.

We report here the development of phenylamino-1,3,5-triazine derivatives as novel nonsteroidal progesterone receptor (PR) antagonists. PR plays key roles in various physiological systems, including the female reproductive system, and PR antagonists are promising candidates for clinical treatment of multiple diseases. By using the phenylamino-1,3,5-triazine scaffold as a template structure, we designed and synthesized a series of 4-cyanophenylamino-1,3,5-triazine derivatives. The synthesized compounds exhibited PR antagonistic activity, and among them, compound 12n was the most potent (IC50 = 0.30 mu M); it also showed significant binding affinity to the PR ligand-binding domain. Docking simulation supported the design rationale of the compounds. Our results suggest that the phenylamino-1,3,5-triazine scaffold is a versatile template for development of nonsteroidal PR antagonists and that the developed compounds are promising lead compounds for further structural development of nonsteroidal PR antagonists.

To evaluate the inhibition of by-products that exist in pretreated lignocellulose hydrolysate on bioethanol fermentation, quantitative structure-activity relationship (QSAR) models were established in the present study. These models have the potential to predict the fermentation inhibition to minimize the experimental effort. They also provided an innovative methodology for removing fermentation inhibitors purposefully and for optimizing pretreatment parameters and thus could enhance the bioethanol yield. The results indicated that the fermentation inhibition of phenolic aldehyde were stronger than that of phenolic acid followed by phenolic alcohol in which the fermentation inhibition was weakened by the existence of the methoxy group in the benzene ring. Meanwhile, the formation of the intramolecular hydrogen bonds of fermentation inhibitors also played an important role in weakening their fermentation inhibition. The individual fermentation inhibition of fermentation inhibitors was found strongly related to their molecular descriptors. Furthermore, ferulic acid was chosen as the representative inhibitor for the primary investigation on the combined fermentation inhibition of the various complex binary fermentation inhibitor mixtures, which co-existed in the lignocellulose hydrolysate. As indicated by the results, antagonism occurred mainly under the higher ferulic acid concentrations in the binary mixtures, while a simple additive effect was generated.
