Title: Innovations by Thomas W. Wakefield

Introduction

Thomas W. Wakefield is a notable inventor based in Ann Arbor, MI (US). He has made significant contributions to the field of biomedical research, particularly in the development of synthetic peptides for anticoagulation therapies. With a total of 4 patents, his work focuses on creating less toxic agents for the reversal of heparin and low molecular weight heparin anticoagulation.

Latest Patents

One of his latest patents involves peptides designed for heparin and low molecular weight heparin anticoagulation. These synthetic protamine-like polycationic peptides possess a total cationic charge that is less than that of n-protamine. In preferred embodiments, arginine residues of n-protamine are replaced with lysine residues to facilitate manufacturing. Selectively, positively charged arginine residues are substituted with uncharged amino acid residues or their analogs, such as glycine or glutamine, to reduce the total cationic charge on the polycationic peptide to a range of about +14 to +18, preferably +16 to +18. Specific embodiments include sequences of 29 and 32 amino acid residues, where clusters of positively charged amino acids are separated by neutral amino acids. Modifications at the C-terminus and N-terminus help mitigate in vivo degradation by carboxypeptidases and aminopeptidases. Additionally, the incorporation of α-helix forming amino acids, such as glutamic acid, promotes anticoagulation reversal.
