Synthetic Macromolecular Inhibitors of Human Leukocyte Elastase. 1. Synthesis of Peptidyl Carbamates Bound to Water-Soluble Polymers: Poly-.alpha.,.beta.-[N-(2-hydroxyethyl)-D,L-aspartamide] and Poly-.alpha.-[N5-(2-hydroxyethyl)-L-glutamine]
摘要:
The design and synthesis of macromolecular peptidyl carbamate inhibitors of human leukocyte elastase (HLE), based on coupling of a low-molecular-weight peptidyl carbamate, succinylalanylalanylprolylmethyl isopropyl carbamate, with a linear hydrophilic polymer, poly-alpha,beta-[N-(2-hydroxyethyl)-D,L-aspartamide] or poly-alpha-[N-5-(2-hydroxyethyl)-L-glutamine], is described. The covalent linkage between a flexible linear polymer and a peptidyl carbamate inhibitor of HLE did not compromise in vitro inhibitory capacity. The macromolecular peptidyl carbamates reported here represent a novel class of elastase inhibitors with a K-i ranging from 35.5 to 2.0 nM.

A modular approach to the synthesis of trivalent C-glycosidic carbohydrates is described. The approach is illustrated employing carboxylate-terminated C-glycosidic D-mannose, D-glucose, and D-galactose derivatives with different length C1-linked spacer units and also core units with different length linker units attached. The central core scaffold is additionally functionalized via a succinamide-based, conjugatable linker unit, exemplified in an extended multivalent derivative [31] and a pyrene-bearing fluorsecent-labeled tris-C-mannosyl conjugate [33].
