The present invention relates to a group of 1-[(E)-3-(3,4,5-trimethoxyphenyl)prop-2-enoyl]-2,3- dihydropyridin-6-one (piperlongumine) derivatives, analogs and pharmaceutically acceptable salts thereof. The present invention also relates to processes for preparing the same; a pharmaceutical composition and formulation containing a derivative of piperlogumine; and use of the derivatives and analogs for treating cancer.
A compound shown by the general formula [1]
1
(wherein R
1
, R
2
and R
3
are each independently an aromatic hydrocarbon residual group, Y
n−
is an anion derived from a carboxylic acid having 3 or more carbon atoms with substituted fluorine atoms, and n is 1 or 2, provided that R
1
, R
2
and R
3
each is not a phenyl group having substituents at an ortho and/or a meta position), and a composition consisting of the compound and a diazodisulfone compound are disclosed. Use of the compound or the compound as an acid generator for resists produces the effects of improving the profiles of ultra-fine patterns or diminishing sidewall irregularities in ultra-fine patterns. The compound is also useful as a cationic photopolymerization initiator.
