The present invention relates to compositions which inhibit the binding of nerve growth factor to the p75NTR common neurotrophin receptor and methods of use thereof. In one embodiment, the compound which inhibits binding of nerve growth factor to p75NTR comprises, particularly when bound to nerve growth factor, at least two of the following: (1) a first electronegative atom or functional group positioned to interact with Lys34 of nerve growth factor; (2) a second electronegative atom or functional group positioned to interact with Lys95 of nerve growth factor; (3) a third electronegative atom or functional group positioned to interact with Lys88 of nerve growth factor; (4) a fourth electronegative atom or functional group positioned to interact with Lys32 of nerve growth factor; and (5) a hydrophobic moiety which interacts with the hydrophobic region formed by Ile31, Phe101 and Phe86 of nerve growth factor.

A new approach for a shortsynthesis of novel medicinally-important mono-, bis- and tris-1,8-naphthalimide peptidyl derivatives is described. The method generates efficiently 1,8-naphthalimides with variable spacer lengths and charged, polar or hydrophobic residues at desired positions, which can increase binding affinity, conformational stability, intracellular transport and/or biological activity
(20) esters of camptothecin analogs are provided. The compounds are (20) esters of an aminoalkanoic acid or an imidoalkanoic acid and homocamptothecin, which is optionally substituted at the 7, 9, 10, 11, and 12 positions of the homocamptothecin ring. The compounds are useful for treating cancer.
