  • PSMA激活式抗肿瘤前药CPT-Y及其制备方法和应用
    申请人:薪火炙药(北京)科技有限公司
    公开号:CN112294972A
    公开(公告)日:2021-02-02
    本发明提供了一类具有结构通式1或结构通式2的化合物及其制备方法和在制备抗肿瘤药物中的应用。本发明中将前列膜抗原(PSMA)特异性靶向多肽喜树碱,通过化学键进行连接,构建两亲性的PSMA激活前药CPT‑Y(CPT‑Wn和CPT‑Hn)。两亲性化合物的构建可提高喜树碱溶性、稳定性和半衰期,从而提高生物利用度。同时本发明物CPT‑Y通过PSMA介导的主动靶向作用可以将喜树碱定向转运至肿瘤部位释放,从而降低其对健康细胞和正常组织的杀伤力,改善耐药性的同时,提升抗肿瘤效应。

Notably, the most active compound 8 displayed the highest protective effect (50% effective concentration (EC50) = 4.31 μM) against tert-butyl, hydroperoxide-induced, SH-SY5Y neurotoxicity cells, which was much better than the baicalein (EC50 = 24.77 μM) and edaravin
    黄芩素是中药黄芩(Scutellaria altissima L.)中著名的有效成分,已被证明具有有效的神经保护和抗血小板聚集作用,且副作用很少。同时,最近的研究表明,将氨基酸引入黄芩素可以提高其神经保护活性。在本研究中,设计、合成并筛选了一系列新的黄芩素氨基酸生物对叔丁基、氢过氧化物诱导的 SH-SY5Y 神经毒性细胞的神经保护作用以及标准甲基噻唑四唑对正常 H9C2 细胞系的毒性(MTT) 测定。此外,所有新合成的化合物均通过 1H-NMR、13C-NMR 和高分辨率质谱 (HR-MS) 进行表征。结果表明,大多数化合物提供比黄芩素更有效的神经保护作用,与阳性药物依达拉韦相当。它们对正常的 H9C2 细胞没有表现出明显的细胞毒性。值得注意的是,活性最强的化合物 8 对叔丁基、氢过氧化物诱导的 SH-SY5Y 神经毒性细胞显示出最高的保护作用(50% 有效浓度 (EC50) = 4.31

    The development of a new decarboxylative cross‐coupling method that affords terminal and substituted alkynes from various carboxylic acids is described using both nickel‐ and iron‐based catalysts. The use of N‐hydroxytetrachlorophthalimide (TCNHPI) esters is crucial to the success of the transformation, and the reaction is amenable to in situ carboxylic acid activation. Additionally, an inexpensive
