cascade as part of their mode of action to reduce the growth of COX-1/2-expressing tumor cells. With the aim to increase the antiproliferative activity by strengthening the inhibitory potency against COX-2, F, Cl, or CH3 substituents were introduced into the acetylsalicylic acid (ASA) moiety. Each structural modification improved COX-2 inhibition. Especially compounds with F substituents at ASA-But-PtCl3
三氯化钾[η2-((prop-2-en/but-3-en)-1-yl)-2-乙酰氧基苯甲酸]铂(II)型蔡斯盐衍生物(ASA-Prop-PtCl3/ASA-But-合成了 PtCl3 衍生物,并对其结构、稳定性和生物活性进行了表征。据推测,先导 ASA-Prop-PtCl3 和 ASA-But-PtCl3 干扰花生四烯酸级联,作为其作用模式的一部分,以减少表达 COX-1/2 的肿瘤细胞的生长。为了通过增强对 COX-2 的抑制效力来提高抗增殖活性,在乙酰水杨酸 (ASA) 部分引入了 F、Cl 或 CH3 取代基。每个结构修饰都改善了 COX-2 抑制。特别是在 ASA-But-PtCl3 处具有 F 取代基的化合物在 1 µM 时已达到约 70% 的最大可实现抑制率。COX-1/2 阳性 HT-29 细胞中 PGE2 的形成被所有 F/Cl/CH3 衍生物抑制,表明细胞系统中的 COX
