ABSTRACT:
Compounds are described having a structure according to Formula I or Formula II:wherein: X is selected from the group consisting of O, NH, and S; Y is selected from the group consisting of O and S; m is from 1 to 3; n is from 1 to 5; R1and R3are each independently selected from the group consisting of H, hydroxy, lower alky, lower alkoxy, halo, amino, aminoalkyl, nitro, heteroaryl, —OC(═O)R6, —O(C═O)OR6; and —O(C═O)N(R6)2; and R2is side chain such as an acetic acid side chain, where p is O to 4, R5is hydroxy, alkoxy or amino, and R6is H or lower alkyl, or a pharmaceutically acceptable salt thereof. The compounds are useful for the treatment of cancer.
