EVIDENCE FOR THE INVOLVEMENT OF CYTOCHROME P-450-DEPENDENT MONOOXYGENASES IN THE ALLYLIC HYDROXYLATION OF TERPINEOLS BY NICOTIANA TABACUM CELL CULTURES

, p. 731 - 736 (1994)
A microsomal preparation isolated from suspension cells of Nicotiana tabacum was able to catalyse the hydroxylation of terpineols and their acetates at the allylic positions.The hydroxylase activities depend strictly on the presence of NADPH as the reducing cofactor and on molecular oxygen as the donor.The hydroxylases were inhibited by cytochrome P-450 enzyme inhibitors, such as carbon monoxide, metyrapone and miconazole.Thus it was established that the hydroxylases are cytochrome P-450-dependent monooxygenases. - Key words: Nicotiana tabacum; Solanaceae; cell cultures; monooxygenase; hydroxylase; allylic hydroxylation; cytochrome P-450; terpineols.

The behavior of several epoxides when treated with NbCl5 was studied. In general, the studied epoxides reacted rapidly with NbCl5, giving, in most cases, more than one product (chlorohydrins, products containing solvent residues, as well as rearrangement products). A detailed study was performed to verify the effects of the temperature (rt, 0°C, or -78°C) and of the NbCl5 molar concentration on the composition of the products, yield, and time required for the reactions.
