Two novel glucosylated zinc(ІІ) phthalocyanines 7a-7b, as well as the acetyl-protected counterparts 6a-6b, have been synthesized by the Cu(I)-catalyzed 1,3-dipolar cycloaddition between the propargylated phthalocyanine and azide-substituted glucoses. All of these phthalocyanines were characterized with various spectroscopic methods and studied for their photo-physical, photo-chemical, and photo-biological
通过在炔丙基化的酞菁和叠氮化物取代的葡萄糖之间进行Cu(I)催化的1,3-偶极环加成反应,合成了两种新型的葡萄糖基化的酞菁锌锌(a)7a-7b,以及乙酰基保护的对映体6a-6b。 。所有这些酞菁都通过各种光谱方法进行了表征,并对其光物理,光化学和光生物学特性进行了研究。以葡萄糖为靶向单元,酞菁7a-7b对MCF-7乳腺癌细胞的特异性亲和力超过人类胚胎肺成纤维细胞(HELF),显示出更高的细胞摄取率。光照后,两种光敏剂均对MCF-7细胞显示出高的细胞毒性,IC50低至0.032 µM,这归因于它们在生物介质中的高细胞摄取和低聚集趋势,促进细胞内活性氧(ROS)的产生。共聚焦激光荧光显微镜研究还表明,它们与MCF-7细胞的溶酶体(而非线粒体)具有较高的选择性亲和力。结果表明,这两种葡糖基化锌(II)酞菁类药物是靶向光动力疗法的潜在抗癌药。
