ZD 9331

(R)-Plevitrexed ((R)-ZD 9331; (R)-BGC9331) is a less active enantiomer of Plevitrexed[1]. Plevitrexed is an orally active and potent thymidylate synthase (TS) inhibitor[2]. (R)-Plevitrexed is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
