Novel mono- and dihydroxy phenylethylamine derivatives useful in treating melanoma are provided having the formulae (Ia, Ib or Ic). In the above formulae, Ra is hydrogen or -COORb, Rb is hydrogen or C¿1-6? alkyl; R?e and Re¿ independently represent hydrogen and hydroxy, Rf is hydrogen, C¿1-4? alkyl or halogen, X is -CHOH-, -CH2-oxygen or sulphur, m is zero or 1, W is oxygen or sulphur, and -ODrug, -NHDrug and -N(Drug)2 each represent a residue of a therapeutically active agent. The above compounds are prodrugs which are inactive until metabolised by enzymes expressed by host melanoma cells. The invention allows a greater amount of active agent to be used while reducing systemic side effects.
本发明提供了一种在治疗黑色素瘤方面有用的新型单和双羟基苯乙胺衍生物,其化学式为(Ia,Ib或Ic)。在上述化学式中,Ra为氢或-COORb,Rb为氢或C1-6烷基;Re和Re'独立地表示氢和羟基,Rf为氢,C1-4烷基或卤素,X为-CHOH-,-CH2-氧或硫,m为零或1,W为氧或硫,-ODrug,-NHDrug和-N(Drug)2分别表示治疗活性剂的残基。上述化合物是前药,在被宿主黑色素瘤细胞表达的酶代谢之前是不活性的。本发明允许使用更多的活性剂而减少全身副作用。
