| | Human RNR Inhibition Effect |
| Description: | The inhibitory activity against the ribonucleotide reduction reaction (hereinafter referred to as RNR reaction) of the test compound was determined by measuring the formation of deoxycytidine diphosphate (hereinafter referred to as dCDP) from cytidine diphosphate (hereinafter referred to as CDP) by the following method.Human M1 subunit and human M2 subunit (mutant lacking amino terminal 59 amino acids), which are fused a histidine tag at the amino terminus, are overexpressed in Escherichia coli and are solubilized after collection, and histidine tagged human M1 and M2 proteins were purified on a nickel chelate column.For measuring the inhibitory activity of the test compound against the RNR reaction, the method described in the document [CANCER RESEARCH 64, 1-6, 2004] was referred to. |
