Title: Innovations and Contributions of Katsura Hata

Introduction

Katsura Hata is a prominent inventor based in Tsukuba, Japan. He has made significant contributions to the field of pharmaceutical formulations and antimalarial drug screening. With a total of 13 patents to his name, Hata's work has had a substantial impact on medical research and development.

Latest Patents

One of Hata's latest patents is a formulation comprising liposomes. This formulation includes liposomes that contain 0.7 to 3.0 mol % of eritoran or a pharmaceutically acceptable salt thereof, along with 0.5 to 3.0 mol % of a PEGylated phospholipid. Another notable patent involves methods of screening for compounds that inhibit the biosynthesis of GPI in malaria parasites. In this invention, Hata and his team successfully isolated GWT1 (PfGWT1), an enzyme involved in GPI biosynthesis in malaria parasites. They discovered that degenerate mutant DNAs with a lower AT content than the DNA encoding the PfGWT1 protein can complement the phenotype of GWT1-deficient yeast. This invention provides the GWT1 protein of malaria parasites and methods for screening antimalarial drugs using degenerate mutant DNAs.
