In Vitro Structure−Activity Relationship and In Vivo Characterization of 1-(Aryl)-3-(4-(amino)benzyl)urea Transient Receptor Potential Vanilloid 1 Antagonists
摘要:
The synthesis and structure-activity relationship of 1-(aryl)-3-(4-(amino)benzyl)urea transient receptor potential vanilloid 1 (TRPV1) antagonists are described. A variety of cyclic amine substituents are well tolerated at the 4-position of the benzyl group on compounds containing either an isoquinoline or indazole heterocyclic core. These compounds are potent antagonists of capsaicin activation of the TRPV1 receptor in vitro. Analogues, such as compound 45, have been identified that have good in vivo activity in animal models of pain. Further optimization of 45 resulted in compound 58 with substantially improved microsome stability and oral bioavailability, as well as in vivo activity.

Disclosed is a pigment dispersion containing at least a pigment, a liquid medium and a high-molecular dispersant. The high-molecular dispersant is a block polymer represented by A-B or A-B-C, in which A, B and C each represent a polymer block and the A and C blocks may be the same or different. The block polymer and its production process are also disclosed. The high-molecular dispersant is free of problems of a smell, coloration, a heavy metal and cost, and its use can provide a pigment dispersion excellent in the dispersion stability of a pigment.

Monoamine oxidase (MAO) exists in two forms distinguishable by substrate specificity. Inhibition of MAO A is believed to be responsible for the antidepressant activity of MAO inhibitors. A group of N-arylacetamides are highly specific inhibitors of MAO A, some with IC50 values in the 10-100 nM range. The requirements for high activity and specificity include a nearly linear tricyclic aromatic portion but a larger and a smaller central ring component. The amide group, which is best acetamido, is optimally placed para to the smaller central group. The size and shape of the aromatic moiety appear to be the major influence on activity and specificity for MAO A.
