proliferation of CA-OV3 cells was measured with a MTS assay. Results: Out of the thirty-four synthesized compounds, eight are newderivatives. The synthesized compounds were characterized by 1H NMR, 13C NMR, and HRMS. Biological evaluation of these β-phenylacrylophenone derivatives in CA-OV3 cells showed interesting antiproliferative activities providing initial structure – activity information. Conclusion:
背景:卵巢癌仍然是一种五年生存率很低的疾病。因此,需要新颖的疗法。天然查耳酮及其合成衍生物已在包括抑制癌细胞生长在内的许多领域显示出生物活性。 目的:建立查尔酮衍生物文库,包括新颖的结构,并确定其对卵巢癌细胞生长的抑制作用及其与结构-活性的关系。 方法:用取代的苯乙酮与芳族醛之间的Claisen-Schmidt缩合反应,以中等至极好的收率和良好的纯度生产了一系列新型查耳酮。用MTS测定法测量CA-OV3细胞的细胞增殖。 结果:在34种合成化合物中,有8种是新衍生物。合成的化合物通过1 H NMR,13 C NMR和HRMS进行表征。在CA-OV3细胞中对这些β-苯基丙烯酮衍生物进行的生物学评估显示出有趣的抗增殖活性,提供了初始结构-活性信息。 结论:在34种测试的化合物中,有14种显示出显着的活性,其中一些显示在100 µM时几乎完全抑制了生长。结构-活性关系表明,对A环的修饰是宽容的,对

In the present study, the four series of N‐acetyl/N‐carbothioamide/N‐carboxamide/N‐phenyl‐based new bispyrazolines have been synthesized. These symmetrical bisheterocyclic products were prepared efficiently from the ring‐closure reactions of new bischalcones 2a‐d with appropriate cyclizing agents (hydrazine hydrate, thiosemicarbazide, semicarbazide, and phenyl hydrazine) under the alkaline ethanolic
