In 2019,Bioorganic Chemistry included an article by Karamitri, Angeliki; Sadek, Mirna S.; Journe, Anne-Sophie; Gbahou, Florence; Gerbier, Romain; Osman, Mai B.; Habib, Samy A. M.; Jockers, Ralf; Zlotos, Darius P.. Recommanded Product: 14660-52-7. The article was titled 《O-linked melatonin dimers as bivalent ligands targeting dimeric melatonin receptors》. The information in the text is summarized as follows:
A series of dimeric melatonin analogs 3a-e obtained by connecting two melatonin mols. through the methoxy oxygen atoms with spacers spanning 16-24 atoms and the agomelatine dimer 7 were synthesized and characterized in 2-[125-I]-iodomelatonin binding assays, bioluminescence resonance energy transfer (BRET) experiments, and in functional cAMP and β-arrestin recruitment assays at MT1 and MT2 receptors. The binding affinity of 3a-e generally increased with increasing linker length. Bivalent ligands 3a-e increased BRET signals of MT1 dimers up to 3-fold compared to the monomeric control ligand indicating the simultaneous binding of the two pharmacophores to dimeric receptors. Bivalent ligands 3c and 7 exhibited important changes in functional properties on the Gi/cAMP pathway but not on the β-arrestin pathway compared to their monomeric counterparts. Interestingly, 3c (20 atoms spacer) shows inverse agonistic properties at MT2 on the Gi/cAMP pathway. In conclusion, these findings indicate that O-linked melatonin dimers are promising tools to develop signaling pathway-based bivalent melatonin receptor ligands.

Ethyl 5-bromovalerate(cas: 14660-52-7) belongs to bromides. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact.Recommanded Product: 14660-52-7
