The present invention generally relates to substituted heterocyclic derivatives (the compounds of Formula (I)), processes for their preparation, pharmaceutical compositions containing said compounds, their use as G-protein coupled receptor (GPR) agonists, particularly as GPR40 agonists and methods of using these compounds in the treatment of GPR40 mediated diseases or conditions such as Type 2 diabetes, obesity, dyslipidemia, hyperlipidemia, hypercholesterolemia, and hypertriglyceridemia.
Acylguanidines as Bioisosteres of Guanidines: <i>N</i><sup>G</sup>-Acylated Imidazolylpropylguanidines, a New Class of Histamine H<sub>2</sub> Receptor Agonists
demonstrated by HPLC-MS, the acylguanidines (bioisosteres of the alkylguanidines) were absorbed from the gut of mice and detected in brain. In GTPase assays using recombinant receptors, acylguanidines were more potent at the guineapig than at the human H2R. At the hH1R and hH3R, the compounds were weak to moderate antagonists or partial agonists. Moreover, potent partial hH4R agonists were identified. Receptor

2-(2, 2-Disubstituted ethenyl-and ethyl)-2-imidazoline derivatives (11, 14) were prepared by direct cyclization of active intermediates, 3, 3-disubstituted acrylimidic ethyl esters (9, 10), with ethylenediamine. The stereoisomers, (Z)-and (E)-3-phenyl-3-pyridylacrylic acid esters (6c-e), nitriles (7c-e) and amides (8c-e), as well as (Z)-and (E)-3-phenyl-3-pyridylacrylimidic acid esters (10c-e), and (Z)-and (E)-2-(2-pyridylethenyl)-2-imidazolines (11c-e), were isolated. Their structures are discussed. Compounds 11 and 14 showed potent hypoglycemic activity.
