2′-Deoxy-1-methylpseudocytidine, a stable analog of 2′-deoxy-5-methylisocytidine

Add time:08/02/2019    Source:sciencedirect.com

2′-Deoxy-5-methylisocytidine is widely used in assays to personalize the care of patients infected with HIV, hepatitis C, and other infectious agents. However, oligonucleotides that incorporate 2′-deoxy-5-methylisocytidine are expensive, because of its intrinsic chemical instability. We report here a C-glycoside analog that is more stable and, in oligonucleotides, pairs with 2′-deoxyisoguanosine, contributing to duplex stability about as much as a standard 2′-deoxycytidine and 2′-deoxyguanosine pair.
