  Regulatory molecules for the 5-HT3 receptor ion channel gating system

  摘要：

  Substituted benzoxazole derivatives which possess a nitrogen containing heterocycle at C2 are selective partial agonists of the 5-HT3 receptor. Alteration of substituents on the benzoxazole nucleus affords both agonist-like and antagonist-like compounds, and uniquely modifies the function of the 5-HT3 receptor ion channel gating system. SAR and corroborative computational docking study for these partial agonists successfully explained structure and function of the 5-HT3 receptor. (c) 2007 Elsevier Ltd. All rights reserved.

  This invention provides a serotonin 5-HT 3 receptor partial activator which has a serotonin 5-HT 3 receptor activating action, in addition to its serotonin 5-HT 3 receptor antagonism, and does not cause constipation as a side effect. Particularly, based on the finding that newly synthesized benzoxazole derivatives typified by the compounds of the following formula (2) have strong serotonin 5-HT 3 receptor antagonism and serotonin 5-HT 3 receptor activating action, this invention provides these benzoxazole derivatives as serotonin 5-HT 3 receptor partial activators. 1 In the above formula, R 1 to R 4 may be the same or different from one another and each represents a hydrogen atom, a halogen atom, a substituted or unsubstituted lower alkyl group, a substituted or unsubstituted lower alkenyl group or a substituted or unsubstituted amino group, or two groups of R 1 and R 2 may be linked together to form a ring structure, namely benzene ring; R 5 represents a hydrogen atom, a substituted or unsubstituted lower alkyl group or a substituted or unsubstituted lower alkenyl group; and m is an integer of 1 to 4.
