A series of C5 substituted analogs of 2'-deoxyuridine triphosphate and 2'-deoxycytidine triphosphate were synthesized and investigated their substrate properties for thermostable DNA polymerases during polymerase chain reaction (PCR). The PCR assays indicated that the relative yield of the full-length product is dependent on whether the substitution is on dU or dC, and on the nature of the polymerase.
