further studied for its antitumor activity in mice. The in vivo result indicated that D1 could significantly inhibit the growth of breast tumors from tumor-bearing mice, and had no effect on the normal functions of the vital organs in vivo. In addition, D1 could stain MCF-7 cells and emitted bright red fluorescence, being a potential functional agent with both imaging and antitumor activity.
通过使用异佛尔酮将苯并噻唑或萘并噻唑与吲哚单元集成在一起,成功合成了六种新的六甲胺异硫氰酸菁。这些花青显示出强的吸收和具有大的斯托克斯位移的近红外荧光,并显示出优异的稳定性。并且它们已作为体外抗人乳腺癌细胞(MCF-7)的新型抗癌药进行了测试,并且靛蓝花菁D1可以有效降低MCF-7的活力,并且对正常的人类永生化表皮细胞(Hacat)无毒性。花青D1在小鼠中的抗肿瘤活性得到了进一步研究。该体内结果表明,D1可以显着抑制荷瘤小鼠乳腺肿瘤的生长,并且对体内重要器官的正常功能没有影响。此外,D1可以染色MCF-7细胞并发出鲜红色的荧光,是具有成像和抗肿瘤活性的潜在功能剂。
