  Planar triazinium cationic species, from VO2+-assisted cyclization of 1-(2-thiazolylazo)-2-naphthol, shows efficient DNA intercalative binding, visible light-induced anaerobic plasmid DNA photocleavage activity and photocytotoxicity in HeLa and MCF-7 cancer cells by an apoptotic pathway with selective localization of the compound in the nucleus as evidenced from the nuclear staining and confocal imaging.

  Planar triazinium cationic species from vanadyl-assisted cyclization of 1-(2-thiazolylazo)-2-naphthol (H-TAN, 1), 1-(2-pyridylazo)-2-naphthol (H-PAN, 2), 2-(2′-thiazolylazo)-p-cresol (H-TAC, 3) and 6-(2′-thiazolylazo)-resorcinol (H-TAR, 5) were prepared and characterized. A dioxovanadium(V) species [VO2(TAR)] (4) was also isolated. Compounds 1, 2 and 4 were structurally characterized. Both 1 and 2 have planar structures. Complex 4 has VVO3N2 coordination geometry. The cyclised triazinium compound forms a radical species within −0.06 to −0.29 V vs. SCE in DMF–0.1 M tetrabutylammonium perchlorate with a second response due to formation of an anionic species. A confocal microscopic study showed higher nuclear uptake for 1 having a fused thiazole moiety than 2 with a fused pyridine ring. The compounds showed a partial intercalative mode of binding to calf thymus DNA. Compound 1 showed plasmid DNA photo-cleavage activity under argon and photocytotoxicity in HeLa and MCF-7 cells with IC50 values of 15.1 and 3.4 μM respectively in visible light of 400–700 nm, while being essentially non-toxic in the dark with IC50 values of 90.4 and 21.9 μM. A TDDFT study was done to rationalize the experimental data.

  通过1-(2-噻唑偶氮)-2-萘酚（H-TAN，1）、1-(2-吡啶偶氮)-2-萘酚（H-PAN，2）、2-(2'-噻唑偶氮)-对甲酚（H-TAC，3）和6-(2'-噻唑偶氮)-间苯二酚（H-TAR，5）的钒辅助环化反应，制备并表征了平面三嗪阳离子物种。还分离得到了一种二氧钒(V)物种[VO2(TAR)]（4）。化合物1、2和4进行了结构表征。1和2均具有平面结构，复合物4具有VVO3N2配位几何结构。环化的三嗪化合物在DMF-0.1 M四丁基高氯酸铵中形成自由基物种，电位范围为-0.06至-0.29 V vs. SCE，并由于阴离子物种的形成而产生第二个响应。共聚焦显微镜研究表明，与具有 fused 吡啶环的2相比，具有 fused 噻唑基团的1具有更高的细胞核摄取。这些化合物显示出与小牛胸腺DNA的部分嵌插结合模式。在氩气气氛下，化合物1在波长400-700 nm的可见光下表现出质粒DNA光裂解活性，对HeLa和MCF-7细胞分别具有15.1和3.4 μM的IC50值，而在暗处基本无毒，IC50值分别为90.4和21.9 μM。通过TDDFT研究合理化了实验数据。
