Paediatric Drug Development in Japan: Current Status and Future Challenges.

Introduction: Until around 2000, the number of medicinal products labelled for paediatric use was limited worldwide. Regulatory measures to promote paediatric drug development in the US and Europe and the establishment of an international guideline (ICH-E11) have led to an increase in the number of paediatric labels. In Japan, efforts have been made to promote the development of paediatric drugs.

cDNA cloning and expression of isoflavonoid-specific glucosyltransferase from Glycyrrhiza echinata cell-suspension cultures.

A cDNA encoding UDP-glucose: formononetin 7- O-glucosyltransferase, designated UGT73F1, was cloned from yeast extract-treated Glycyrrhiza echinata L. cell-suspension cultures using probes from Scutellaria baicalensis UDP-glucose: flavonoid 7- O-glucosyltransferase. The open reading frame of the UGT73F1 cDNA encodes a 441-amino-acid protein with a predicted molecular mass of 48.
