In order to find efficient new antitumor drugs, a series of novel trifluoromethyl-substituted pyrimidine derivatives were designed and synthesized, and the bioactivity against four human tumor cells (PC-3, MGC-803, MCF-7 and H1975) was evaluated by MTT assay. Compound 17v displayed potent anti-proliferative activity on H1975 (IC50 = 2.27 μΜ), which was better than the positive control 5-FU (IC50 = 9.37 μΜ). Further biological evaluation studies showed that compound 17v induced apoptosis of H1975 cells and arrested the cell cycle at G2/M phase. Furthermore, compound 17v induced H1975 cells apoptosis through increasing the expression of pro-apoptotic proteins Bax and p53 and down-regulating the anti-apoptotic protein Bcl-2. In addition, compound 17v was able to be tightly embedded in the active pocket of EGFR. In summary, these results demonstrated that compound 17v has a potential as a lead compound for further investigation.

Abstract: In order to find efficient new antitumor drugs, a series of novel pyrimidine derivatives containing urea moiety were designed and synthesized, and the antitumor activity of four human tumor cells was evaluated by MTT analysis. The results showed that most of the target compounds exhibited moderate antitumor activity. In particular, the IC50 (concentration required to achieve 50% inhibition of the tumor cell proliferation) value of compound 2-((4-(4-ethylphenoxy)-6-(trifluoromethyl)pyrimidin-2-yl)thio)-N-((4-ethylphenyl)carba-moyl)acetamide for MGC-803 (human gastric carcinoma cell line) was 2.51 ± 0.17 μmol L–1, the anti-proliferative activity was significantly better than the positive control drug 5-fluorouracil. Molecular docking revealed that this compound can bind well to the active site of epidermal growth factor receptor (EGFR), and it may become a potential antitumor drug.

A series of novel phenyl methoxyacrylate derivatives containing a 2-alkenylthiopyrimidine substructure were designed, synthesized, and evaluated in terms of acaricidal activity. The structures of the title compounds were identified by 1H NMR, 13C NMR and high-resolution mass spectra (HRMS). Compound (E)-methyl 2-(2-((2-(3,3-dichloroallylthio)-6-(trifluoromethyl)pyrimidin-4-yloxy) methyl)phenyl)-3-methoxyacr-ylate (4j) exhibited significant acaricidal activity against Tetranychus cinnabarinus (T. cinnabarinus) in greenhouse tests possessing nearly twice the larvicidal and ovicidal activity compared to fluacrypyrim. Furthermore, the results of the field trials demonstrated that compound 4j could effectively control Panonychuscitri with long-lasting persistence and rapid action. The toxicology data in terms of LD50 value confirmed that compound 4j has a relatively low acute toxicity to mammals, birds, and honeybees.

, p. 17427 - 17441 (2017/03/31)
The laccase-catalyzed reaction between unsubstituted catechol and 2-thioxopyrimidin-4(1H)-ones using aerial O2 as the oxidant delivers novel pyrimidobenzothiazoles with high yields in an aqueous solvent system under mild reaction conditions. With 4-substituted catechols, catechol thioethers are formed exclusively. The synthetic protocols developed provide a sustainable approach for these compound classes. In addition, the cytotoxicity of the products against HepG2 cell line is reported. Most compounds exhibit antiproliferative activities with IC50 values at the micromolar level. A structure-activity relationship study will facilitate the further development of these compounds as cytotoxic agents.

Transmembrane protein 16A (TMEM16A), also called Ano1, is a Ca2+ activated Cl? channel expressed widely in mammalian epithelia, as well as in vascular smooth muscle and some tumors and electrically excitable cells. TMEM16A inhibitors have potential utility for treatment of disorders of epithelial fluid and mucus secretion, hypertension, some cancers and other diseases. 4-Aryl-2-amino thiazole T16Ainh-01 was previously identified by high-throughput screening. Here, a library of 47 compounds were prepared that explored the 5,6-disubstituted pyrimidine scaffold found in T16Ainh-01. TMEM16A inhibition activity was measured using fluorescence plate reader and short-circuit current assays. We found that very little structural variation of T16Ainh-01 was tolerated, with most compounds showing no activity at 10 μM. The most potent compound in the series, 9bo, which substitutes 4-methoxyphenyl in T16Ainh-01 with 2-thiophene, had IC50 ～1 μM for inhibition of TMEM16A chloride conductance.

A multi-component double Mannich cyclocondensation of 6-polyfluoroalkyl-2- thiouracils with formalin and heterocyclic amines (2-aminopyridine, 2-aminopyrimidine, 4-aminoantipyrine) proceeded regiospecifically at the C=S and NH centers giving rise to 3-hetaryl-8-polyfluoroalkylpyrimido[2,1-b][1,3,5] thiadiazines. The regioisomeric structure of the products was established by X-ray crystallography, IR and NMR spectroscopy, GLC-MS spectrometry. 6-Trifluoromethyl-2-thiouracil and 8-polyfluoroalkylpyrimido[2,1-b]thiadiazines exhibited weak tuberculostatic activity.
