ABSTRACT:
This invention relates to a method for treating an angiogenesis-related disease. The method includes administering to a subject in need thereof an effective amount of a piperazinedione compound having the formula:In the above formula, each ofand, independently, is a single bond or a double bond; A is H or CH(RaRb) whenis a single bond, or C(RaRb) whenis a double bond; Z is CH(RcRd) whenis a single bond, or C(RcRd) whenis a double bond; each of R1and R2, independently, is H, C(O)Re, C(O)ORe, C(O)NReRf, or SO2Re; and each of Ra, Rb, Rc, Rd, Re, and Rf, independently, is H, C1-C6alkyl, aryl, heteroaryl, C3-C8cycloalkyl, or C3-C8heterocycloalkyl; or Raand Rbtaken together are C3-C8cycloalkyl, C3-C8heterocycloalkyl, aryl, or heteroaryl; or R1and Raor R1and Rbtaken together are C3-C8cycloalkyl, C3-C8heterocycloalkyl, aryl, or heteroaryl; provided that one of Rcand Rdis aryl or heteroaryl.
