Biotransformation of (+)- and (-)-camphorquinones by plant cultured cells

Biotransformation of (+)- and (-)-camphorquinones with suspension plant cultured cells of Nicotiana tabacum and Catharanthus roseus was investigated. It was found that the plant cultured cells of N. tabacum and C. roseus reduce stereoselectively the carbonyl group of (+)- and (-)-camphorquinones to the corresponding alpha-keto alcohols.

Biotransformation of thujopsene by Caragana chamlagu

Biotransformation of thujopsene (1) using a cell suspension culture of Caragana chamlagu for 14 days gave mayurone (2, 52%) and two new compounds, 3beta-hydroxy-4-thujopsene (4, 16%) and 3beta-epoxythujopsa-5beta-ol (3, 22%).
