Bisantrene HCl (CL216942 and NSC337766), the hydrochloride salt of Bisantrene, is potent inhibitor of topoisomerase II and DNA intercalators with anticancer activity. P-glycoprotein-mediated multiple drug resistance (MDR1) may be studied using it as a model compound. One potential Rac1 inhibitor is bisantrene. DNA-protein crosslinking, DNA single-strand breaks, and inhibition of DNA replication are all caused by bisantrene intercalating with and altering the structure of DNA. While this agent's activity is similar to that of doxorubicin, it does not show cardiotoxicity.

Biological Activity


Targets Topoisomerase
ln Vitro On oligopurine-oligopyrimidine sequences, bisantrene diHClide enhances DNase I cleavage, whereas on alternating purine-pyrimidine sequences, it somewhat diminishes cleavage activity [1]. The incorporation of [3H]uridine into RNA and [3H]thymidine into DNA is inhibited by bisantrene diHClide [2].
ln Vivo A number of experimental cancers, such as P388 leukemia, L1210 leukemia, Liebermann's plasmacytoma, B16 melanoma, colon neoplasia 26, and Ridgway osteosarcoma, respond well to the antineoplastic drug bisantrene diHClide [3]. The effectiveness of bisantrene hydrochloride varies between 1.56 and 150 mg/kg, contingent upon the tumor model employed, treatment frequency, modality, and schedule [3]. Macrophages were pretreated with bisantrene hydrochloride (25, 50, and 100 mg/kg; intraperitoneally; once), and animals injected with P815 tumor cells shown anticancer effects [3]. Neo mice are given dose-dependent doses of bisantrene diHClide (10-150 mg/kg; i.v.; once) to cause leukopenia. Bisantrene hydrochloride toxicity targeting B cells and macrophages [4].
Enzyme Assay In ETN buffer (1 mM EDTA, 10 mM Tris, pH 7.0, with NaCl to obtain the desired ionic strength), measurements are performed at 25°C. Spectrophotometric or fluorometric methods are used to observe binding in the ligand absorption or emission region, respectively, following the addition of scalar quantities of DNA to a newly made drug solution. The range of bound drug fractions is 0.15-0.85 in order to prevent significant systematic errors that could arise from experimental errors in extinction coefficients or fluorescence quantum yield. Data are assessed. A Perkin-Elmer Lambda 5 apparatus and an MPF66 fluorometer, both of which have a Haake F3-C thermostat, are used for spectroscopic measurements[1].

Additional Infomation Bisantrene Hydrochloride is the hydrochloride salt of an anthracenyl bishydrazone with antineoplastic activity. Bisantrene intercalates with and disrupts the helical structure of DNA, resulting in DNA single-strand breaks, DNA-protein crosslinking, and inhibition of DNA replication. This agent is similar to doxorubicin in activity, but unlike doxorubicin, does not exhibit cardiotoxicity.
