A series of benzylideneacetophenone derivatives have been synthesized and found to show potent inhibition of the lipidperoxidation (LPO) in rat liver microsomes. All 19 compounds prepared in this series are LPO inhibitors. The highest activity was found in para hydroxy derivatives with two meta tert-butyl substituents.
Lithium aluminium hydride (LAH) reduction of 4′-hydroxychalcones, followed by dehydration, yielded 4-cinnamylidene-2,5-cyclohexadien-1-ones in 19–42% yields. The LAH reduction of 4′-acetoxychalcones also gave the same products in improved yields.

through acid or base-catalyzed aldol condensation. The anticancer activity of the newly synthesized compounds was assessed against a range of women-specific cancercell lines, including A2780 (ovarian cancer), HeLa and C33a (cervical cancer), and MDA-MB-453, MDA-MB-231 and MCF-7 (breast cancer). The majority of these compounds demonstrated remarkable cytotoxicity against the tested cancercells. Compound
通过酸或碱催化的醇醛缩合反应,合成了一系列由丁香醛衍生的新型查尔酮类似物。新合成化合物的抗癌活性针对一系列女性特异性癌细胞系进行了评估,包括 A2780(卵巢癌)、HeLa 和 C33a(宫颈癌)以及 MDA-MB-453、MDA-MB-231 和 MCF -7(乳腺癌)。这些化合物中的大多数对测试的癌细胞表现出显着的细胞毒性。化合物2a对选定的雌性癌细胞表现出最有希望的抗增殖活性,同时对人类正常细胞也表现出最弱的细胞毒性。因此,本研究基于药物疗效和安全性考虑,选择其作为活性化合物。研究结果表明,化合物2a通过引起显着的 DNA 损伤并引发强烈的 DNA 损伤反应,诱导细胞凋亡和 G2/M 期停滞。此外,结果表明化合物2a影响FAK的磷酸化和分布,从而抑制细胞粘附和迁移。此外,化合物2a在抑制小鼠体内 A2780 衍生的异种移植肿瘤生长方面表现出优异的潜力,且对其体重没有任何影响。组织分布
