This disclosure relates to methods of inhibiting vascular hyperplasia using polyamines, polyamine analogs, and conformationally restricted polyamine analogs, or a conjugate of a polyamine, polyamine analog, or conformationally restricted polyamine analog. Polyamines, polyamine analogs, conformationally restricted polyamine analogs, and conjugates thereof are useful in reducing stenosis and restenosis of blood vessels and grafts.
COMPOSITIONS AND METHODS FOR TRANSPORT OF MOLECULES WITH ENHANCED RELEASE PROPERTIES ACROSS BIOLOGICAL BARRIERS

Conjugates of a cargo molecule with a transporter molecule are disclosed, where the cargo molecule and the transporter molecule are linked covalently by a releasable linker. The cargo of the conjugate can be a biologically active agent or a reporter molecule. The transporter modulates the transport of the cargo across a biological barrier (e.g., a cell membrane) compared to the transport of the unconjugated cargo. Releasable linkers suitable for rapid and facile conjugation to various types of cargo and transporters are also disclosed, along with methods for using the linkers in the synthesis of conjugates.

This disclosure relates to methods of inhibiting cell motility or cell migration, and of treating diseases involving cell migration or cell motility, using polyamine analogs, such as conformationally restricted polyamine analogs. The diseases to be treated include immune disorders, inflammatory conditions, infection, abnormal immune responses, undesired angiogenesis, tumor cell metastasis or invasion, atherosclerosis, vascular graft occlusion, transplant rejection, other complications of transplants, glomerulonephritis, arthritis, inflammatory responses subsequent to stroke or ischemia, and asthma.
