Covalent modification of biological macromolecules
First Claim
1. A method of covalently modifying a fibrinogen protein, comprising:
- (I) subjecting a fibrinogen protein to denaturing and reducing conditions to produce a reduced, denatured fibrinogen protein comprising one or more thiol groups;
(II) reacting the reduced, denatured fibrinogen protein with one or more norbornene moieties underconditions sufficient to produce a photoinitiated radical thiol-ene coupling reaction between at least one of the one or more norbornene moieties and at least one of the one or more thiol groups on the reduced, denatured fibrinogen protein, thereby providing a covalently modified fibrinogen protein,wherein the one or more norbornene moieties comprise a polymer selected from the group consisting of;
poly(lactic acid) (PLA), polyglycolide (PGA), copolymer of PLA and PGA (PLGA), poly(vinyl alcohol) (PVA), poly(ethylene glycol) (PEG), poly(ethylene oxide), poly(ethylene oxide)-co-poly(propylene oxide) block copolymer, poloxamine, polyanhydride, polyorthoester, poly(hydroxy acid), polydioxanone, polycarbonate, polyaminocarbonate, poly(vinyl pyrrolidone), poly(ethyl oxazoline), carboxymethyl cellulose, and hydroxyalkylated cellulose.

Abstract
The present disclosure provides a method of covalently modifying a biological macromolecule, the method comprising subjecting a reaction mixture comprising: (a) a biological macromolecule comprising one or more thiol groups; and (b) a molecule comprising one or more olefin or alkyne moieties to a radical reaction under conditions sufficient to produce the covalently modified biological macromolecule. The present disclosure also provides a method of covalently modifying a biological macromolecule, the method comprising subjecting a reaction mixture comprising: (a) a molecule comprising one or more thiol groups; and (b) a biological macromolecule comprising one or more olefin or alkyne moieties to a radical reaction under conditions sufficient to produce the covalently modified biological macromolecule. The present disclosure further provides a covalently modified biological macromolecule prepared by any of the disclosed methods. The covalently modified biological macromolecules may be further crosslinked to form a scaffold.
