Title: Innovations of Philip C Andrews

Introduction

Philip C Andrews is a notable inventor based in Ann Arbor, MI (US). He has made significant contributions to the field of biochemistry, particularly in the development of synthetic peptides for anticoagulation therapies. With a total of 6 patents, his work has the potential to impact medical treatments significantly.

Latest Patents

One of his latest patents focuses on peptides for heparin and low molecular weight heparin anticoagulation. This invention presents less toxic agents for the reversal of heparin or low molecular weight heparin anticoagulation. The synthetic protamine-like polycationic peptides developed by Andrews have 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 4 to 5 clusters of 2 to 4 positively charged amino acids are separated by 2 to 6 neutral amino acids. Modifications at the C-terminus and N-terminus can mitigate in vivo degradation by carboxypeptidases and aminopeptidases. Additionally, the incorporation of α-helix forming amino acids, such as glutamic acid, promotes anticoagulation reversal.
