PUBLICATIONS: Over 380 publications in Refereed Journals DRUGS DISCOVERED There are three (3) drugs currently used in clinic. They were initially discovered in this laboratory. This includes: o Gancyclovir - For Cytomegalo Viral infection o Lamivudine - For Heapatitis B Virus infection o Clevudine -- For Hepatitis B Virus infection Three additional chemicals and one Chinese medicine formula were discovered and are currently at different stages of Clinical Trial for the treatment of cancer as well as HIV and HBV infection. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
