ABSTRACT:
Chemically modified .alpha.-macroglobulin is conformationally locked by cross-linking .alpha..sub.2 M with a bi-functional peptide crosslinker, and then modified with methylamine, to provide conformational intermediates with limited conformational change. These modified compounds have a high binding affinity for inflammatory cytokines including TNF-.alpha. and IL-1.beta.. When administered in vivo, the modified .alpha..sub.2 M (MAC) protects against development of septic shock, and is an effective treatment aid in treating mammals with established septic shock.
