Achievement:

1. Medicine chemistry

Invented a new method to synthesize the skeleton of the Celphalatoxine,which is an anti-cancer reagent. Developed a new type of non-toxic compounds, which are highly effective for curing theschistosomiasis.

2. RNA and DNA cleavage reagents

Discovered that the N-phospho-histidine could cleave RNA and DNA by hydrolysis on the phospho-diester bond, Also found that N-phospho-serine in histidine could cleave DNA and RNA by a bio-mimic mechanism Cooperated with OhioUniversity for site specific cleavage of RNA and DNA.

3. Auto-catalysis of the N-phospho-amino acids:

It was found that N-phospho-amino acids could not only self-assemble into oligo-peptides in organic and aqueous condition from pH 2 to 9, at the temperature 0-80oC, but also phosphorylate the nucleosides into nucleotides and oligo-nucleotides. Therefore, N-phospho-amino acids could produce the peptide library,nucleotide library and the peptide-nucleotide conjugated library in one pot reaction.

4. Origin of Life

N-phospho-amino acids also could form the LB-membrane and lipsome structure, together with auto-catalysis for peptide and nucleotides formation, it was proposed as the minimum evolved system.
