multitarget-directed ligands (MTDLs) to confront the key pathological aberrations. A novel series of triazinoindole derivatives were designed and synthesized. In vitrostudies revealed that all the compounds showed moderate to good anticholinesterase activity; the most active compound 23e showed an IC50 value of 0.56 ± 0.02 μM for AChE and an IC50 value of 1.17 ± 0.09 μM for BuChE. These derivatives are also

The present invention provides a pigment dispersant: that is capable of remarkably ameliorating fluidity of a liquid product, such as an ink or a paint, which contains particles of a pigment, such as a black azo pigment, in a dispersed state; that can suppress aggregation of piment particles; that prevents occurrence of foreign substances; and that is capable of producing a colored article excellent in optical density. Provided is a pigment dispersant being a compound represented by the following formula (1).

The invention relates to a process for continuously preparing N-alkyl(meth)acrylamides by reacting alkyl (meth)acrylates with high-boiling amines. A catalyst activation and specific workup technique achieve product qualities which have not been achieved to date. In addition, very high space-time yields and overall yields can be achieved.
