The present invention refers to compounds of formula (I) or a pharmaceutically acceptable salt thereof: Formula (I). These compounds have FFA4/GPR120 receptor (FFA4) agonistic properties. The invention refers also to pharmaceutical compositions comprising these compounds, chemical processes for preparing them and their use in the treatment or prophylaxis of diseases associated with FFA4 receptor activity in animals, in particular humans.
The structure-activity relationship of phenylpyrazole derivative 1 was investigated for the development of novel anti-HIV agents. Initial efforts revealed that the diazenyl group can be replaced by an aminomethylene group. In addition, we synthesized various derivatives by the reductive amination of benzaldehydes with 5-aminopyrazoles and carried out parallel structural optimization on the benzyl group and the pyrazole ring. This optimization led to a six-fold more potent derivative 32j than the lead compound 1, and this derivative has a 3',4'-dichloro-(1,1'-biphenyl)-3-yl group. (C) 2013 Elsevier Ltd.
