The primary molecular mechanism of action is the initial biological effect caused directly by the bioactive compound of interest. In other words, the primary molecular mechanism of action is the most “upstream” activity induced by the compound of interest that results in the observed effects. The...
or 7 carbon atoms with a methyl substituent on either or both of the number 2 and number 4 carbon atoms; and X repre- 15 sents either hydrogen (if the compound is an acid), or (if the compound is a salt) either an alkali metal, such as sodium, or ammonium, or a mono- or di...
when R1 is an alkylene group, R3 and R4 are polyatomic groups, and when G1 is a substituent defined for Nu, an adjacent R3 or R4 can be the group: ##EQU6## X1 is a ballasting group of sufficient size to render said compound immobile in an alkali-permeable layer of the photographic...
The mixture was stirred for another 2 h, evaporated to about 1 mL and added hexane to get the solid, which was filtered and dried to give the final compound XIE62-1004 (720 mg, 65%). 1H NMR (400 MHz, DMSO-d6): δ 8.83 (bs, 2H), 7.52–7.46 (m, 5H), 7.31–7.32 ...
To provide a vinylpyrrolidone/vinyl acetate copolymer which is extremely reduced in thermal yellowing and is usable even at high temperatures and which can dissolve in water to give a transparent solution. The vinylpyrrolidone/vinyl acetate copolymer of the present invention has a residual vinylpyrrolidon...
