Remedies / preventives (therapeutic or preventive agents) against frequent urination (pollakiuria) / urinary incontinence which contain as an active ingredient compound having a tropone structure or pharmacologically acceptable salt thereof and a novel compound having the tropone structure. The compounds having a tropone structure and having the above pharmacological effects are those represented by, for example, general (1):
wherein R1 and R2 represent each a hydrogen atom, lower alkyl group, etc., R3 represents -OR or -NR2 ; R4, R5 and R12 represents each a hydrogen atom or a lower alkyl group, X represents a nitrogen atom or CH, Z represents -CHAr2, an unsubstituted or substituted phenyl, etc. m is 1 or 2. These compounds are novel ones excluding those wherein Z is -CH Ar2.

Previously, we identified 1-(2-(4-bromophenoxy) ethoxy)-3-(4-(2-methoxyphenyl) piperazin-1-yl) propan- 2-ol (1) as a novel Hsp90 inhibitor with moderate activity through virtual screening. In this study, we report the optimization process of 1. A series of analogues containing the 1-phenylpiperazine core scaffold were synthesized and evaluated. The structure-activity relationships (SAR) for these compounds was also discussed for further molecular design. This effort afforded the most active inhibitor 13f with improved activity in not only target-based level, but also cell-based level compared with the original hit 1. (C) 2014 Elsevier Ltd.

evaluated as a novel class of selective ligands for the dopamineD3receptor. Binding affinities of target compounds were determined (using the method of radioligand binding assay). Compared to comparator agent BP897, compounds 2a and 2c were found to demonstrate a considerable binding affinity and selectivity for D3receptor, and especially compound 2h was similarly potent and more selective D3R ligand than
