Nukiangendines A and B,two novel 13,14-seco-abietanes from Abies nukiangensis

From Abies nukiangensis, two novel 13,14-seco-abietane diterpenes, nukiangendines A (1) and B (2) were isolated. Their relative structures were determined by extensive NMR and HRMS spectroscopic analysis. The absolute configuration of 1 was established by ECD calculations. Compound 1 showed significant anti-hepatitis C virus (HCV) effects.     

Synthesis,anticancer activity,toxicity evaluation and molecular docking studies of novel phenylaminopyrimidine—(thio)urea hybrids as potential kinase inhibitors

Thirty-two novel urea/thiourea compounds as potential kinase inhibitor were designed, synthesized and evaluated for their cytotoxic activity on breast (MCF7), colon (HCT116) and liver (Huh7) cancer cell lines. Compounds 10, 19 and 30 possessing anticancer activity with IC₅₀ values of 0.9, 0.8 and 1.6 μM respectively on Huh7 cells were selected for further studies. These hit compounds were tested against liver carcinoma panel. Real time cell electronic sensing assay was used to evaluate the effects of the compounds 10, 19 and 30 on the growth pattern of liver cancer cells. Apoptotic cell death and cell cycle analysis upon treatment of liver carcinoma cells with hit compounds were determined. A significant apoptotic cell death was detected upon treatment of Huh7 and Mahlavu cells with compound 30 after 48 h of treatment. Additionally, compound 10 caused cell cycle arrest at G0/G1 phase. Mutagenicity of hit compounds was evaluated. Assertively, these compounds were not found to be mutagenic on Salmonella typhimurium strains TA98 and TA100. To understand the binding modes of the synthesized compounds, molecular docking studies were performed using the crystal data of VEGFR and Src-kinase enzymes in correlation with anticancer activities.

电场中LiF分子吸附H_2的理论研究

采用密度泛函理论方法研究了电场中H_2在LiF分子上的吸附行为.结果表明,无电场时,H_2能在Li与F原子上形成弱的物理吸附.外加电场可显著提高其吸附强度, H_2在Li/F上的吸附能由无电场时的-0.112/-0.122eV提高到场强为0.005 a. u.时的-0.122/-0.171 eV, H_2吸附在F上时更稳定.利用分子中的原子量子理论(QTAIM)方法研究了电场增强吸附的机理,表明电场促进了H_2与LiF间的电荷转移,同时使LiF及H_2极化,增强了其间的静电作用,从而提高了吸附强度.电场中LiF最多能吸附10个H_2,相应的质量密度达43.5 wt%.表明电场诱导LiF材料吸附H_2是一种具有潜力的储氢方法.
