ABSTRACT:
Conjugates having a clinically useful delivery vehicle linked to a biologically active species which acts to increase vascular permeability and expand blood volume at or in proximity to the tumor site are disclosed. The vehicle-linked species may be, for example, a vasoactive agent, a substance that recruits or amplifies a vasoactive species, a drug, or a pharmaceutical compound. Suitable biological species comprises peptides, lipids, carbohydrates, or their derivatives. Chemical or recombinant DNA methods suitable for linking the species to the vehicles are indicated. A therapy is disclosed which comprises administering the vasoactive conjugate and delivering a diagnostic agent or a therapeutic agent at an optimal time thereafter, when tumor vasculature is maximally affected.
