An efficient synthesis of new naphthospiro chromanone scaffolds using ionic liquids as a green solvent under microwave irradiation is presented. The reaction was also studied under conventional elevated temperature conditions. The structures of newly synthesized compounds have been elucidated by means of IR, H-1 NMR, C-13 NMR, and mass spectrometry data. All compounds were screened for their antimicrobial activity.

synthesis of 4-bromo- 2H-chromenes and 2H-thiochromenes and of 1-bromo-3,4-dihydronaphthalene from the corresponding ketones and PBr3 is described. In some instances, significant quantities of the phosphonic acids (3) are isolated. Conversion of the bromo compounds to the lithio derivatives provides access to a wide range of novel 4-substituted 2H-chromenes and 2H-thiochromenes.

A novel series of spirobenzo[h]chromene and spirochromane derivatives was designed, synthesized and evaluated as potential anticancer agents against MCF-7 (human breast carcinoma), HT-29 (human colorectal adenocarcinoma) and A549 (human lung carcinoma) cell lines using MTT assay. Eight compounds 7, 8e, 13a-e and 16 showed a better anticancer activity than that of sorafenib, the multi-kinase inhibitor
设计并合成了一系列新的螺环苯并[ h ]色烯和螺苯并二氢吡喃衍生物,并将其用作针对MCF-7(人乳腺癌),HT-29(人结肠直肠腺癌)和A549(人肺癌)细胞系的潜在抗癌药。 MTT测定。八种化合物7、8e,13a-e和16显示出比索拉非尼(IC 50值在1.78和5.47μM之间的多激酶抑制剂或厄洛替尼(IC 50值在20μM以上)的多激酶抑制剂)更好的抗癌活性。代表性化合物8e,13c和16选择通过EGFR,B-RAF和微管蛋白聚合测定进行进一步的机理研究。化合物16是最有效的EGFR抑制剂(IC 50 = 1.2μM),但是化合物8e,13c和16显示出中等的微管蛋白聚合抑制作用。这些化合物的分子对接研究揭示了它们可能结合到EGFR和B-RAF激酶活性位点中的方式。新开发的化合物代表了一种治疗不同类型癌症的有治疗前景的方法。
