Biotransformation of (RS)-tropic acid in suspension cultures of Coffea arabica, Datura innoxia, Eucalyptus perriniana and Nicotiana tabacum
Suspension cultures of Datura innoxia and Nicotiana tabacum are able to convert (RS)-tropic acid into its glucose esters (2RS)-3-hydroxy-2-phenylpropionyl ß-D-glucopyranoside and (2RS)-2-0-(3-hydroxy-2-phenylpropionyl)-D-glucose whereas a cultures of Eucalyptus perriniana converts it into its glucoside (2RS)-3-0-ß-D-glucopyranosyl-2-phenylpropionic acid in addition to glucose esters. Suspension cultures of Coffea arabica converts: (RS)-2-(4-hydroxyphenyl) propionic acid into its glucose and sucrose esters and a small amount of its glucoside; and (RS)-ethyl 2-(4-hydroxyphenyl) propionate into its gentiobioside. The formation of sucrose esters and linkage of the aglycone to the C-6 position of glucose are characteristic of the biotransformation of carboxylic acids by suspension cultures of C. arabica. The suspension culture of C. arabica selectively converted (R)-tropic acid into its isotrehalose ester on administration of (RS)-tropic acid.
