Synonyms: | 2KT4YN1DP7, [(2R,3S,5R)-5-(2-amino-6-oxo-1H-purin-9-yl)-3-hydroxyoxolan-2-yl]methyl [(2R,3S,5R)-5-(4-amino-2-oxo-1,3,5-triazin-1-yl)-2-(hydroxymethyl)oxolan-3-yl] hydrogen phosphate, SGI-110 |
Definition: | Guadecitabine is a dinucleotide antimetabolite composed of a decitabine linked via phosphodiester bond to a deoxyguanosine, with potential antineoplastic activity. Following metabolic activation via cleavage of the phosphodiester bond and incorporation of the decitabine moiety into DNA, guadecitabine inhibits DNA methyltransferase, thereby causing non-specific, genome-wide hypomethylation, and induction of cell cycle arrest at S-phase. This agent is resistant to cytidine deaminase, which may result in gradual release of decitabine both extra- and intra-cellularly, leading to prolonged exposure to decitabine. |
