Popis: The synthesis of new phospha sugar analogues or phosphorus heterocycles and their biological activities as novel anticancer agents are reported in this article. A 1,2-dibromo-1,2-dideoxy phospha sugar derivative, 2,3-dibromo-3-methyl-1-phenylphospholane 1-oxide (2), was prepared from 1-phenyl-3-methyl-2-phospholene 1-oxide (1), and the yield and ratio of diastereomers 2a to 2d were changed by a catalyst such as manganese(IV) oxide and manganese(II) bromide. The antitumor activities of the mixture of dibromides 2 and the separated diastereomeric components 2a to 2d of the dibromides were evaluated by MTT in vitro method against the human leukemia cell lines of K562 and U937. The results showed that all of the diastereomers 2a to 2d as well as the diastereomer mixture exert excellent anticancer activity, and moreover, among them, diastereomer 2d showed the highest antitumor activity.
