Claim:
A method for treating or inhibiting angiogenesis which comprises administering to a patient in need of such treatment a therapeutically effective amount of a compound of formula (I): wherein the dotted line between positions 11 and 12 represent an optional C11-C12 bond; R is independently selected from the group consisting of hydroxy, C 1 -C 10 alkoxy, NH—C 1 -C 10 alkyl, and NH-hydroxy(C 1 -C 10 )alkyl; R′ is independently selected from the group consisting of hydroxy and C 1 -C 10 alkoxy; R″ is independently selected from the group consisting of hydrogen, hydroxy, C 1 -C 10 alkoxy, NH—C 1 -C 10 alkyl, and NH-hydroxy(C 1 -C 10 )alkyl; and R 1 , R 2 , R 3 , R 4 , R 5 and R 6 are independently selected from the group consisting of hydrogen, hydroxy, chloro, bromo, C 1 -C 10 alkyl, C 1 -C 10 alkoxy, and C 1 -C 10 alkoxycarbonyl, provided that R″ is not hydrogen when there is a C11-C12 bond.
