the toxicity of ara-c was effectively reversed by an excess of deoxycytidine , but not by cytidine or other conventional nucleosides , which is highly suggestive that the molecular mechanism of ara-c toxicity is based on its anti-metabolic role in the salvage pathway of biosynthesis of dna deoxycytidine .
