Ibutilide (U70226E free base) is a potent antiarrhythmic compound that extends the action potential duration. It effectively blocks the rapidly activating delayed rectifier potassium current (I Kr ) in AT-1 cells [1].

Ibutilide Fumarate (U70226E) 是一种 III 类抗心律失常药物，可作用于急性心梗阻塞。

Dibrospidium Free Base is a dispirotripiperazine derivative and alkylating agent with potential antineoplastic and anti-inflammatory activities. The duration of DNA synthesis inhibition in tumor cells was found to correlate with spirobromine antitumor activity. Spirobromin is superior to prospidin by the power of the anti-inflammatory effect. Spyrobromin can diminish the latent period of the development of tumours in the experimental rats at intraperitoneal administration. At intragastric administration of the drug no decrease was noted in the latent period and no increase of tumours was observed in the experimental groups of the animals as compared with control. Dibrospidium has been examined for the treatment of bone cancer. The oral route of administration is the most safe with respect to the oncogenic risk. It was noted that spirobromin exerted the most pronounced toxic action on erythrocytes. Dibrospidium is used for the treatment of acute leukemias (mainly in combinatio......

Iso-Fludelone is the third-generation epothilone B analogue with potential anti-mitotic and antineoplastic activites. Iso-fludelone binds to tubulin and induces microtubule polymerization and stabilizes microtubules against depolymerization, which may result in the inhibition of cell division, the induction of G2 M arrest, and apoptosis. Compared to other generations of epothilones, iso-fludelone exhibits increased stability, water solubility, potency, duration of action, tumor penetration as well as reduced toxicity. In addition, this agent is a not a substrate of the P-glycoprotein (P-gp), a multidrug resistance pump often overexpressed in cancer cells. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus).

Carsatrin succinate is the salt form of Carsatin, a purinylpiperazine derivative used as a cardiotonic and antiarrhythmic. Carsatrin acts as positive inotropic agent that increases twitch tension and prolongs the action potential (AP) duration of ventricular muscle without affecting the Na+, K+-ATPase, adenylyl cyclase, phosphodiesterase isozymes, or cardiac myofilaments. Carsatrin’s positive inotropic effect can be prevented by tetrodotoxin but not by the adrenergic antagonists timolol, yohimbine, or prazosin.
