Synthesis and evaluation of homodimeric GnRHR antagonists having a rigid bis-propargylated benzene core
摘要:
The fact that GPCRs might function in a dimeric fashion is currently well accepted. For GnRHR, a GPCR that regulates gonadotropin release, there is evidence that the receptor also functions as a dimer. We here describe the design and synthesis of a set of dimeric GnRHR antagonists in order to understand the interaction of dimeric ligands to the receptor and to address the question whether GnRHR dimerisation is a prerequisite for signalling. Biological evaluation of the compounds shows no discrimination between monomeric and dimeric ligands in respect to binding affinities, however, the dimeric ligands appear to have different functional properties.
