1 Curcumin (1,7-bis(4-hydroxy-3-methoxyphenyl)-1,6-heptadiene-3,5-dione) inhibited noncompetitively rat liver microsomal delta 5 desaturase (Ki = 36 microM) and delta 6 desaturase (Ki = 28 microM). Curcumin fatty acid desaturase 2 Rattus norvegicus
2 The following structural features of curcumin are necessary for the desaturase inhibition: (i) the aromatic ring conjugated with the double bond between the 1 and 2 (or 6 and 7) positions; (ii) both 4-hydroxy and 3-methoxy groups (for both desaturase inhibitions); and (iii) only a 4-hydroxy group (for delta 6 desaturase inhibition).
