TL;DR: The finding that mitochondria synthesize and release melatonin and have their selective G protein-coupled receptor (GPCR) in the outer membrane is described and a new term, “automitocrine,” is proposed to describe this unexpected intracellular organelle ligand–receptor pathway that opens a new research avenue investigating mitochondrial GPCR biology.
Journal ArticleDOI
New selective ligands of human cloned melatonin MT1 and MT2 receptors.

TL;DR: The most potent melatonin receptor agonist, S 25150, is discovered, so far reported in the literature, and new types of selective antagonists, such as S 25567 and S 26131 for MT1 and S 24601 for MT2 are reported.
Journal ArticleDOI
An efficient and reusable heterogeneous catalyst Animal Bone Meal for facile synthesis of benzimidazoles, benzoxazoles, and benzothiazoles
Yassin Riadi,Yassin Riadi,Rachid Mamouni,Rachid Azzalou,Mohammadine El Haddad,Sylvain Routier,Gérald Guillaumet,Said Lazar +7 more
TL;DR: A library of benzimidazoles, benzoxazoles and benzothiazoles was efficiently synthesized by condensation of o-phenylenediamine, o-aminophenol, and oaminothiophenol respectively with aromatic aldehydes in the presence of catalytic amounts of Animal Bone Meal (ABM) and Lewis acids doped ABMs as mentioned in this paper.
Journal ArticleDOI
Functionalization of Imidazo[1,2‐a]pyridines by Means of Metal‐Catalyzed Cross‐Coupling Reactions
TL;DR: This review surveys recent developments (reported in the last fifteen years) in organometallic-chemistry-based methods for the functionalization of imidazo[1,2-a]pyridines by means of reactions such as Sonogashira, Heck, Negishi, Suzuki–Miyaura, and Stille cross-coupling.
Journal ArticleDOI
Pyridine-based lanthanide complexes: towards bimodal agents operating as near infrared luminescent and MRI reporters.

TL;DR: Two prototype Ln(3+) complexes are reported that address requirements for both MRI and luminescence imaging and it is demonstrated that the presence of two H(2)O molecules bound to the LN(3+), beneficial for MRI applications of the Gd( 3+) analogue, is not a major limitation for the development of NIR luminescent agents.
