biological evaluations of the first two enzymatically activatedprodrugs of docetaxel (Taxotere) reported to date. These prodrugs were designed as potential candidates for selective chemotherapy in ADEPT or PMT. They are constituted of a glucuronic acid moiety, a double spacer and the cytotoxic drug, differing only by the spacer substitution. The prodrugs were stable in a buffer, and the in vitro studies
Synthesis of substituted 4-(3-alkyl-1,2,4-oxadiazol-5-ylmethyl)-3,4-dihydro-2H-1,4-benzoxazines and 4-(1H-benzimidazol-2-ylmethyl)-3,4-dihydro-2H-1,4-benzoxazines

Substituted 2H-1,4-benzoxazines were synthesized from substituted 2-amino phenols and 1,2-dibromoethane using K2CO3 in good to excellent yields. The cyclized products were further reacted with alkyl bromides to obtain the desired N-substituted 3,4-dihydro-2H-1,4-benzoxazines.
使用K 2 CO 3由取代的2-氨基苯酚和1,2-二溴乙烷合成了2 H -1,4-苯并恶嗪,收率良好。使环化产物进一步与烷基溴反应,得到所需的N-取代的3,4-二氢-2 H -1,4-苯并恶嗪。
