Calculate Digit Verification of CAS Registry Number 1403840-46:
(9*1)+(8*4)+(7*0)+(6*3)+(5*8)+(4*4)+(3*0)+(2*4)+(1*6)=129
129 % 10 = 9

Beta-ionone substituted curcumin analogue as well as preparation method and application of beta-ionone substituted curcumin analogue

-

Paragraph 0025; 0026; 0027; 0028; 0030; 0031; 0032-0035, (2017/07/12)

The invention discloses a beta-ionone substituted curcumin analogue as well as a preparation method and application of the beta-ionone substituted curcumin analogue. The structure of the curcumin analogue is shown as a formula (I), wherein R is substituted or unsubstituted phenyl and substituted or unsubstituted heteroaryl; a substituent group on the phenyl or the heteroaryl is selected from one or more of alkyl, alkoxyl, halogen, nitryl and dialkyl amine. A pharmacological effect test proves that a beta-ionone segment is introduced into a parent structure of curcumin, so that the anti-inflammatory activity of the compound can be remarkably improved, levels of TNF-alpha (Tumor Necrosis Factor-alpha) and IL-6 (Interleukin-6) are reduced and the probability of occurrence of infectious shock is reduced. (The formula (I) is shown in the description.).
