Buisson, Didier,Quintin, Jerome,Lewin, Guy
, p. 1035 - 1038 (2007)
Regioselective O-demethylation of the flavones tangeretin (1) and 3-hydroxytangeretin (6) into their 4′-O-demethylated metabolites was performed by using an Aspergillus niger strain. This method serves as a straightforward alternative to multistep synthes

Paragraph 0129-0131; 0133, (2019/12/09)
The invention discloses a nobiletin derivative or a pharmaceutically acceptable salt thereof as well as a preparation method and application thereof. The nobiletin derivative has a structural formula(I) shown in the description, in the formula, R1, R2, R3 and R4 are respectively selected from hydrogen, halogen, hydroxyl, amino, C1-6 substituted or non-substituted alkoxy, a C1-6 substituted or non-substituted ester group, C1-6 substituted or non-substituted alkamino and a C1-6 substituted or non-substituted amide group; R5 is selected from a C3-9 substituted or non-substituted aromatic ring and a C3-9 substituted or non-substituted aromatic heterocyclic ring; and X is selected from O or NR6. The nobiletin derivative or the pharmaceutically acceptable salt thereof, which is disclosed by theinvention, is novel in structure, and in addition, the compound has an excellent inhibition function on P-gp, can be prepared into a P-gp inhibitor, is capable of treating and/or preventing related diseases caused by P-gp, particularly diseases related to tumor drug resistance, or can be mixed and used with other medicines and used as a drug resistance reversal agent, has a high reversion multiple, and is capable of remarkably improving medicine effects of medicines.

We present a practical synthesis of the polymethoxylated citrus flavone nobiletin that is suitable for use on a hundred gram scale. Ready availability of this compound and its derivatives will aid detailed chemical-biological investigations of their biological activities, including activation of signaling via the cAMP-dependent protein kinase A/extracellular signal-related protein kinase/cAMP response element-binding protein pathway.
