Abstract: Chemotherapeutic conjugates of a peptide substrate to a phosphoramide chemotherapeutic agent in which a peptide substrate is covalently linked to the chemotherapeutic agent by a linker with an aminoarylmethyl or aminoheteroaryl moiety, wherein the linking of the peptide to the chemotherapeutic agent inhibits the cytotoxic activity of the chemotherapeutic agent, the peptide is a substrate for proteolytic cleavage by a tumor-specific enzyme; and the linker is capable of undergoing 1,6-elimination in vivo upon cleavage of the peptide substrate. Methods for synthesizing and methods of using the conjugates are also disclosed.

Abstract: A class of phosphono-hydroisoquinoline compounds is described for treatment to reduce neurotoxic injury associated with anoxia or ischemia which typically follows stroke, cardiac arrest or perinatal asphyxia. The treatment includes administration of a phosphono-hydroisoquinoline compound alone or in a composition in an amount effective as an antagonist to inhibit excitotoxic actions at major neuronal excitatory amino acid receptor sites. Compounds of most interest are those of Formula I: ##STR1## wherein each of R.sup.1 through R.sup.4 is hydrido, wherein each of Z.sup.1 and Z.sup.2 is hydroxyl, wherein W is a single bond connecting the phosphorus atom with the aromatic ring and wherein the A ring is aromatic. Also disclosed are two classes of intermediate compounds having a fully unsaturated A ring, which intermediate compounds are useful in methods to make product compounds of Formula I.
