Cholinesterase inhibitor plays an important role in the treatment of patients with Alzheimer’s disease (AD). Herein, we report the medicinal chemistry efforts leading to a new series of 1,3-dimethylbenzimidazolinone derivatives. Among the synthesised compounds, 15b and 15j showed submicromolar IC50 values (15b, eeAChE IC50 = 0.39 ± 0.11 μM; 15j, eqBChE IC50 = 0.16 ± 0.04 μM) towards acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). Kinetic and molecular modelling studies revealed that 15b and 15j act in a competitive manner. 15b and 15j showed neuroprotective effect against H2O2-induced oxidative damage on PC12 cells. This effect was further supported by their antioxidant activity determined in a DPPH assay in vitro. Morris water maze test confirmed the memory amelioration effect of the two compounds in a scopolamine-induced mouse model. Moreover, the hepatotoxicity of 15b and 15j was lower than tacrine. In summary, these data suggest 15b and 15j are promising multifunctional agents against AD.

Pyrimidine derivatives useful as a gastrointestinal prokinetic agent, represented by formula STR1 wherein X is O or NR5, Y is O, S or NR5 wherein R5 is a hydrogen atom, a C1 -C6 alkyl group or the like; R1 and R2 may be the same or different and each is a hydrogen atom, a C1 -C6 alkyl group or the like; R3 is CN, or COOR6 wherein R6 is a C1 -C6 alkyl group, a C3 -C6 cycloalkyl group, an aryl group or the like; R4 is --SR7 or --NR8 R9 wherein R7 is a C1 -C6 alkyl group; R8 is a C1 -C6 alkyl group or the like; R9 is a hydrogen atom, a C1 -C6 alkyl group or the like, or R8 and R9 may represent, together with the nitrogen atom to which they are attached, an N-substituted piperazine ring of formula (X) STR2 wherein R10 represents a C1 -C6 alkyl group or the like or a pharmacologically acceptable salt thereof. The above-mentioned compounds are useful as a gastrointestinal prokinetic agent used for the therapy of digestive tract diseases.
