Dichloro(bipyridine)platinum 是一种强效的铂类抗肿瘤配合物,是顺铂(Cisplatin)的结构类似物。它通过联吡啶配体增强分子的脂溶性和平面堆积能力。该化合物通过与 DNA 发生共价结合或嵌入式结合,形成顺式-Pt-DNA 加合物,从而干扰 DNA 复制和转录过程。研究表明,该类配合物能有效激活促凋亡信号通路,对多种耐药性肿瘤细胞系具有显著的生长抑制作用,是开发新型金属抗癌药物的重要基础分子。
MitoNeoD is a novel mitochondria-targeted O2(⋅−) probe that can be used in vivo. It prevents DNA intercalation. MitoNeoD incorporates a carbon-deuterium bond, and enhances O2(⋅−) selectivity.
Pinafide is a rodenticide and anti-protozoal agent. Pinafide shows strong cytostatic activity against both HeLa and KB cells and is moderately toxic to both mice and rats. It has been proved active against experimental tumors and shown to be inhibitor of two DNA viruses. Pinafide blocks cell growth by inhibiting DNA and RNA synthesis. It has been shown to bind to double-helical DNA by intercalation. Pinafide inhibited the activity of M. tuberculosis NAD⁺-dependent DNA ligase A at concentrations of 50 uM. At the chemical screening was found that pinafide inhibited B-Myb transcriptional activity in luciferase assays. The cross placental-barrier studies showed that 3H-pinafide was present in the 14-day fetuses.
Amikhellin HCl, an antimitotic drug, is a synthetic water-soluble derivative of khellin, an alkaloid extracted from seeds of Ammi Visnaga. Amikhellin has been used so far mostly as a vasodiator. Amikhellin binds to double-stranded DNA by an intercalation process. It inhibits the DNA-polymerase from murine sarcoma leukemia virus.
