Some 4-aryl-4H-chromenes 3a-h, 5a-g, 7a-g and 9a-g were obtained by reaction of 3-substituted phenol 1, 4, 6
and 8 with α-cyanocinnamonitrile derivatives 2. We explored the structure activity relationship (SAR) of 4-aryl-4Hchromenes
with modification at the 4- and 7-positions. The antitumor activity of the synthesized compounds was investigated
in comparison with the standard drugs Vinblastine and Doxorubicin using microculture tetrazolium (MTT) colorimetric assay.
Some compounds were found to have good in vitro antitumor activity. The structure-activity relationship (SAR) study
revealed that the antitumor activity of 4-aryl-4H-chromenes was significantly affected by the lipophilicity, the calculated Log
P value and the balance between 7-hydrophilic or hydrophobic substituent and hydrophobic substituent on the benzene ring at
4-position. The structures of the newly prepared compounds were confirmed by elemental analysis and spectral data.
通过3-取代酚1、4、6和8与α-氰基肉桂腈衍生物2的反应,获得了一些4-芳基-4H-色烯3a-h、5a-g、7a-g和9a-g。我们探讨了在4-和7-位进行修饰的4-芳基-4H-色烯的结构-活性关系(SAR)。使用微培养四唑盐(MTT)比色法,与标准药物长春碱和多柔比星相比,研究了合成的化合物的抗肿瘤活性。一些化合物显示出良好的体外抗肿瘤活性。结构-活性关系(SAR)研究发现,4-芳基-4H-色烯的抗肿瘤活性显著受到亲脂性、计算得到的Log P值以及7-亲水或疏水取代基与4-位苯环上的疏水取代基之间的平衡的影响。新制备的化合物的结构通过元素分析和光谱数据得到了确认。
