Niacin hydrochloride is a water-soluble vitamin of the B complex occurring in various animal and plant tissues. It is needed by the body for the formation of coenzymes NAD and NADP. It possesses PELLAGRA-curative, vasodilating, and antilipemic properties.
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.
Pterosin B (Standard) 是 Pterosin B 的标准品。适用于定量分析、质量控制及生化实验等相关研究。Pterosin B 是一种广泛存在于绿色植物的叶子和芽中,是盐诱导性激酶 3 (Sik3) 信号转导抑制剂。Pterosin B 可促进 G6pc 的表达,对Ang II诱导的心肌细胞肥大具有保护作用,通过调节NAD(P)H氧化酶2/4的表达水平发挥作用。
