APIs
Yamasa manufactures small molecular active pharmaceutical ingredients (APIs) of nucleic acid related compounds. Yamasa provides APIs for new drugs at all stage from R&D to commercial, and for generic drugs.
In addition to the listed products which are examples of APIs for generic drugs, we are manufacturing other APIs.
Mizoribine
Mizoribine is an immunosuppressive drug which is applied for prevention of renal transplant rejection, lupus nephritis, and rheumatoid arthritis.
Vidarabine
Vidarabine is an anti-virus drug which is applied for herpes simplex and herpes zoster.

Sugar nucleotides
Sugar nucleotides are the substances made of nucleotide and sugar. Sugar nucleotides are the activated forms of monosaccharides acting as glycosyl donors.Sugar nucleotides play a role as substrates in the enzymatic synthesis of oligosaccharides. For example, sugar nucleotides are used for glycosylation modification to biopharmaceutical.
Yamasa supplies 8 types of sugar nucleotides with high quality which can be used for glycoengineering by enzymatic synthesis technology.
