The known chalcone (±)-sanjuanolide (1) can be isolatedfrom Dalea frutescens. This study presents a convergent strategy for the first total synthesis of ( R)-, ( S)-, and (±)-sanjuanolide (1). The key step for synthesizing ( R)- and ( S)-1 was a Corey-Bakshi-Shibata enantioselective carbonyl reduction to construct the C-2″ configuration. ( R)-1 efficiently inhibited the lipopolysaccharides (LPS)-induced

reduction. Further mechanistic studies showed that S07 treatment triggered intense DNAdamage and provoked strong DNAdamage response in a dose-dependent manner. These findings suggested that sanjuanolide derivatives, especially S07, selectively induced CRPC cell death by triggering intense DNAdamage and DNAdamage response.
仍然迫切需要更有效的疗法来治疗去势抵抗性前列腺癌 (CRPC),这是前列腺癌患者死亡的主要原因。在这项研究中,设计、合成和评估了一系列的 Sanjuanolide 衍生物作为潜在的抗 CRPC 药物。大多数化合物对 CRPC 细胞具有出色的选择性,IC 50值 < 20 µM。此外,观察到对人类正常肝 MIHA 细胞和正常前列腺基质肌成纤维细胞 WPMY-1 细胞的副作用最小,IC 50 > 100 µM。代表化合物S07减慢 CRPC 细胞的增殖速度,促进细胞凋亡并引起 G2/M 期积累,以及 G1/G0 期减少。进一步的机理研究表明,S 07处理引发了强烈的 DNA 损伤,并以剂量依赖性方式激发了强烈的 DNA 损伤反应。这些发现表明,sanjuanolide 衍生物,尤其是S07,通过触发强烈的 DNA 损伤和 DNA 损伤反应选择性地诱导 CRPC 细胞死亡。
