N-(2,2-Dimethyl-2-(2-nitrophenyl)acetyl)-4-aminocyclophosphamide as a potential bioreductively activated prodrug of phosphoramide mustard
چکیده انگلیسی

N-(2,2-Dimethyl-2-(2-nitrophenyl)acetyl)-4-aminocyclophosphamide isomers (DMNA-NH-CPA, 4) were synthesized stereospecifically from Boc-l-Hse(OBn)-OH and the degradation of the corresponding reduced amine 5a was investigated by UV/vis spectroscopy and LC/MS. The rate of cyclization of 5a was found to increase with decreasing pH, with half-lives ranging from 3.2 to 54 min at pH 4–7.4, suggesting that the cyclization is catalyzed by the hydronium ions. LC/MS analysis of the degradation products of 5a indicates that 4-aminocyclophosphamide is rapidly released from 4 upon reductive activation under acidic conditions and further decomposes into the cytotoxic phosphoramide mustard. These results validated 4-aminocyclophosphamide as a prodrug form of phosphoramide mustard and suggest that compound 4 can potentially be used as a prodrug of phosphoramide mustard for bioreductive activation.

N-(2,2-Dimethyl-2-(2-nitrophenyl)acetyl)-4-aminocyclophosphamide isomers were synthesized as potential bioreductively activated prodrugs of phosphoramide mustard and their mechanism of reductive activation was investigated.Figure optionsDownload as PowerPoint slide
