A method of inhibiting angiogenesis in a patient includes administering to the patient an effective amount of squalamine or a pharmaceutically acceptable salt of squalamine. Alternatively, a compound according to the following Formula (III) (or a pharmaceutically acceptable salt thereof) can be administered: ##STR1## wherein Z.sub.5 is .alpha.-H or .beta.-H; each of the substituents Z.sub.7 is selected from the group of --H, --OH, --SH, --NH.sub.2, --F, --(C.sub.1 -C.sub.3)-alkyl, and --(C.sub.1 -C.sub.3)-alkoxy; and one of the substituents Z.sub.12 is --H and the other is --H or --OH. X' is a polyamine side chain of the formula --X.sub.1 --(CH.sub.2).sub.p --X.sub.2 --(CH.sub.2).sub.q --N(R.sup.II)(R.sup.III), wherein one of X.sub.1 and X.sub.2 is --N(R.sup.IV) and the other is selected from the group of --N(R.sup.V), --O, --S, and --CH.sub.2. R.sup.IV and R.sup.V are each --H or --(C.sub.1 -C.sub.3)-alkyl, p and q are each an integer of from 0 to 5 (but both are not 0). R.sup.II and R.sup.III in the formula for X' are each --H, --(C.sub.1 -C.sub.3)-alkyl, or --(CH.sub.2).sub.r --N(R.sub.10)(R.sub.11) wherein r is an integer from 2 to 5 and R.sub.10 and R.sub.11 are each --H or --(C.sub.1 -C.sub.3)-alkyl. R' in Formula (III) is --H or --(C.sub.1 -C.sub.3)-alkyl, and Y' is --(C.sub.1 -C.sub.10)-alkyl, unsubstituted or substituted with --CO.sub.2 H, --OH, --NH--SO.sub.2 CF.sub.3, --SO.sub.3 H, --PO.sub.3 H.sub.2, --OSO.sub.3 H, --CF.sub.3, --F, ##STR2##
在患者中抑制血管生成的方法包括向患者施用一定量的鲨烷或鲨烷的药用盐。或者,可以施用以下式(III)所示的化合物(或其药用盐):##STR1## 其中Z.sub.5为α-H或β-H;Z.sub.7的取代基选自--H、--OH、--SH、--NH.sub.2、--F、--(C.sub.1 -C.sub.3)-烷基和--(C.sub.1 -C.sub.3)-氧烷基的群;其中一个取代基Z.sub.12为--H,另一个为--H或--OH。X'为具有以下式--X.sub.1 --(CH.sub.2).sub.p --X.sub.2 --(CH.sub.2).sub.q --N(R.sup.II)(R.sup.III)的多胺侧链,其中X.sub.1和X.sub.2中的一个为--N(R.sup.IV),另一个选自--N(R.sup.V)、--O、--S和--CH.sub.2的群。R.sup.IV和R.sup.V分别为--H或--(C.sub.1 -C.sub.3)-烷基,p和q分别为0到5的整数(但两者都不为0)。X'中的公式中的R.sup.II和R.sup.III分别为--H、--(C.sub.1 -C.sub.3)-烷基或--(CH.sub.2).sub.r --N(R.sub.10)(R.sub.11),其中r为2到5的整数,R.sub.10和R.sub.11分别为--H或--(C.sub.1 -C.sub.3)-烷基。式(III)中的R'为--H或--(C.sub.1 -C.sub.3)-烷基,Y'为--(C.sub.1 -C.sub.10)-烷基,未取代或取代为--CO.sub.2 H、--OH、--NH--SO.sub.2 CF.sub.3、--SO.sub.3 H、--PO.sub.3 H.sub.2、--OSO.sub.3 H、--CF.sub.3、--F、##STR2##
