Enzymatic degradation of the hydrogels based on synthetic poly(.alpha.-amino acid)s
Original language description
Biodegradable hydrogels are studied as potential scaffolds for soft tissue regeneration. In this work biodegradable hydrogels were prepared from synthetic poly (a-amino acid)s, poly(AA)s. The covalently crosslinked gels were formed by radical copolymerization of methacryloylated poly(AA)s, e.g. poly[N5-(2-hydroxy-ethyl)-L-Glu- ran-L-Ala-ran-N6-methacryloyl-L-Lys], as a multifunctional macromer with a low-molecular-weight methacrylic monofunctional monomer, e.g. HEMA. Due to their polypeptide backbone, synthetic poly(AA)s are cleavable in biological environment by enzyme-catalyzed hydrolysis. The feasibility of enzymatic degradation of poly(AA)s alone and the hydrogels made from them was studied using elastase, a matrix proteinase involved in tissue healing processes, as a model enzyme. Specificity of elastase for cleavage of polypeptide chains behind the L-Ala residues was reflected in faster degradation of L-Ala-containing copolymers as well as of hydrogels composed of them.
