Myeloid cell leukemia-1 (Mcl-1) is a validated and attractive target for cancer therapy. Over-expression of Mcl-1 in many cancers allows cancer cells to evade apoptosis and contributes to their resistance to current chemotherapeutics. In this study, more than thirty coumarin derivatives with different substituents were designed and synthesized, and their Mcl-1 inhibitory activities evaluated using

In this paper, we report synthesis and spectral characteristics of 24 new F-alkyl-4 coumarins and their synthetic intermediates, the corresponding F-alkyl β-keto esters. The reaction yields depend on the nature of the starting materials and the cyclisation agents. 1H and 19F N.M.R. chemical shifts and coupling constants are assigned in every compound and a new kind of long distance H-F coupling constant
在本文中,我们报告了24种新的F-烷基-4香豆素及其合成中间体,即相应的F-烷基β-酮酯的合成和光谱特征。反应产率取决于原料和环化剂的性质。在每种化合物中都指定了1 H和19 F NMR化学位移和耦合常数,并且观察到了一种新型的长距离HF耦合常数5 J,并通过几何,空间和电子效应将其解释为通过空间耦合。
