We describe a process for engineering a synthetic polymer nanoparticle (NP) that functions as an effective, broad-spectrum metalloproteinase inhibitor. Inhibition is achieved by incorporating three functional elements in the NP: a group that interacts with the catalytic zinc ion, functionality that enhances affinity to the substrate-binding pocket, and fine-tuning of the chemical composition of the polymer to strengthen NP affinity for the enzyme surface. The approach is validated by synthesis of a NP that sequesters and inhibits the proteolytic activity of snake venom metalloproteinases from five clinically relevant species of snakes. The mechanism of action of the NP mimics that of endogenous tissue inhibitors of metalloproteinases. The strategy provides a general design principle for synthesizing abiotic polymer inhibitors of enzymes.

Various zwitterionic polymers, sulfobetaine and phosphoryl choline derivatives were synthesized in order to investigate zwitterionic polymer structures toward surface modification of PDMS, where the adsorption of zwitterionic polymers on polydimethylsiloxane surface treated with air-plasma was induced by the electrostatic interaction,. The electrostatic interaction was evaluated with hydrophilicity. The results suggested that a sulfobetaine polymer with higher molecular weight, lower molecular weight distribution, and shorter alkyl chain afforded high electrostatic interaction. A sulfobetaine polymer bearing phenylazide group showed similar electrostatic interaction with the PDMS surface, and it is a promising material for surface modification ofpolydimethylsiloxane.
