General description
2-Imino-1-imidazolidineacetic acid (cyclocreatine) is an analog of creatine. It is reported to exhibit antitumour effect in some transplanted human and rodent tumours in vivo. It is reported as an efficient substrate for creatine kinase. It is an anticancer and neuroprotective agent. The crystal structure of cyclocreatine has been studied by X-ray diffraction methods. It is reported to crystallize as a zwitterion in the monoclinic system.
Application
2-Imino-1-imidazolidineacetic acid (cyclocreatine) is suitable for use in a study to investigate the growth inhibitory effects of cyclocreatine on LS174T human colon adenocarcinoma implanted subdermally in nude mice. It may be used to evaluate the brain-type creatine kinase (CKB), to study the role of CKB in cigarette smoke-induced bronchial epithelial cell senescence.
