Paragraph 0176; 0178; 0180-0182, (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.

, p. 2965 - 2968 (2007/10/02)
Besides agecorynin C, eupalestin and lucidin dimethyl ether, two new highly oxygenated flavones were isolated from Ageratum houstonianum.Their structures were established by spectroscopic and degradative evidence as 5,6,7,8,2',3',4',5'-octamethoxyflavone and 5,6,7,2',3',4',5'-heptamethoxyflavone. - Key Word Index: Ageratum houstonianum; Asteraceae; Eupatorieae; new octasubstituted and heptasubstituted flavones.
