Nine 5-aryl-2-methyloxazole derivatives were synthesized via gold-catalyzed alkyne oxidation.All of the compounds have been screened for their antiproliferative activities against MCF-7 cell(human breast carcinoma),A549 cell(human lung carcinoma)and Hela cell(human cervical carcinoma)lines in vitro.The results revealed that compounds 1b,1c and 1d exhibited strong inhibitory activities against the MCF-7 cell lines(with IC50values of 4.6,9.7 and 2.2 mmol/L,respectively).
Among the current technologies for post-combustion CO2 capture,amine-based chemical absorption appears to be the most technologically mature and commercially viable method.This review highlights the opportunities and challenges in post-combustion CO2 capture using amine-based chemical absorption technologies.In addition,this review provides current types and emerging trends for chemical solvents.The issues and performance of amine solvents are reviewed and addressed in terms of thermodynamics,kinetics,mass transfer,regeneration and solvent management.This review also looks at emerging and future trends in post-combustion CO2 capture using chemical solvents in the near to mid-term.
