  • Publication number: 20080280837
    Abstract: A method for inhibiting angiogenesis in a subject comprising administering to the subject at least one compound of General Formula (I), wherein the ring or any chiral center(s) may be of any configuration; Z is sulphur, oxygen, CH2, C(O), C(O)HN, NH, NRA or hydrogen, in the case where Z is hydrogen then R1 is not present, RA is selected from the set defined for R1 to R5, X and X? are independently oxygen or nitrogen providing that at least one X of General Formula (I) is nitrogen, X or X? may also combine independently with one of R1 to R5 to form an azide, R1 to R5 are independently selected from the following definition which includes but is not limited to H or an alkyl, acyl, alkenyl, alkynyl, heteroalkyl, aryl, heteroaryl, arylalkyl or heteroarylalkyl substituent of 1 to 20 atoms, which is optionally substituted, and can be branched or linear, and R6 and R7 are hydrogen, or may combine to form a carbonyl function.
