With a total of four patents to his name, his work focuses on developing effective methods for delivering therapeutic agents to the central nervous system.

Latest Patents

One of his latest patents is centered around a BBB-crossing lipid ligand of hetero nucleic acid. The objective of this invention is to provide a nucleic acid agent that can be efficiently delivered to the nervous system, especially the central nervous system, which is often inaccessible due to the blood-brain barrier. This invention aims to produce an antisense effect on a target transcriptional product at the delivery site. The patent describes a double-stranded nucleic acid complex formed by annealing a first nucleic acid strand, which can hybridize to part of a target transcriptional product, to a second nucleic acid strand that is complementary to the first. This second strand is bound to various lipid components, enhancing its delivery capabilities.

Another notable patent involves a nucleic acid complex that is designed to be efficiently delivered to the central nervous system. This invention also provides an antisense effect on a target transcription product at the delivery site. The double-stranded nucleic acid complex consists of a first nucleic acid strand that hybridizes with part of a target transcription product and a second strand that is conjugated to phosphatidylethanolamine or an analog thereof.
