A new and convenient synthetic pathway was developed to produce monosubstituted cyclodextrins with high yields. Each of the β-cyclodextrinderivatives described in this work has an aromatic substituent connected with cyclodextrin core by a pH-sensitive hydrazone linker and a carbon chain. Carbon chains differ in lengths having one or three carbon atoms. The correlation between water solubility and

A series of oxadiazole derivatives possessing morpholine 6a–l were synthesized by nucleophilic substitution reaction of key intermediates [1,3,4]-oxadiazole-2-thiol derivatives 5a–l with 4-(2-chloroethyl) morpholine. Compounds 6a–l were evaluated for their in vitro and in vivo antitumor potential in Dalton’s Lymphoma Ascites (DLA) tumor cells. Among 6a–l series, compound 6a with concentration ∼8.5 μM
