Abstract: The invention provides biologically active compounds that may be reacted with macromolecules, such as albumin, to form covalent linked complexes wherein the resulting complexes exhibit a desired biological activity in vivo. More specifically, the complexes are isolated complexes comprising a biologically active moiety covalently bound to a linking group and a protein. The complexes are prepared by conjugating a biologically active moiety, for example, a renin inhibitor or a viral fusion inhibitor peptide, with purified and isolated protein. The complexes have extended lifetimes in the bloodstream as compared to the unconjugated molecule, and exhibit biological activity for extended periods of time as compared to the unconjugated molecule. The invention also provides anti-viral compounds that are inhibitors of viral infection and/or exhibit anti-fusiogenic properties.

Abstract: The invention provides compositions and methods that are useful for preventing and treating a coronavirus infection in a subject. More specifically, the invention provides peptides and conjugates and pharmaceutical compositions containing those peptides and conjugates that block fusion of a coronavirus, such as the SARS virus, to a target cell. This blocking mechanism prevents or treats a coronavirus infection, such as a SARS infaction, in a subject, such as a human subject.
