New psychoactive substances (NPS) are a heterogeneous and rapidly evolving class of molecules available on the global illicit drug market (e.g smart shops, internet, "dark net") as a substitute for controlled substances. The use of NPS, mainly consumed along with other drugs of abuse and/or alcohol, has resulted in a significantly growing number of mortality and emergency admissions for overdos...
The physiopathology of non-insulin-dependent diabetes mellitus is associated with a dysfunction in the regulation of insulin secretion. The alpha 2-adrenoceptors have been reported to be involved in this alteration, although alpha 2-antagonists containing an imidazoline ring may stimulate insulin secretion independently of alpha 2-adrenoceptor blockage. Recently, a new "imidazoline-binding site...
Many organic sulfones have been shown to possess antibacterial, antimalarial, anthelmintic, antilepral, antineoplastic, anti-inflammatory and antidiabetic acitivities. These sulfones are commonly prepared from sodium benzenesulfinate 1-0 which plays an important role in organic synthesis. However the application of 1-0 in solid-phase synthesis has received relatively less attention. This projec...
Neuropeptide S (NPS) was identified as the endogenous ligand of an orphan receptor now referred to as the NPS receptor (NPSR). In the frame of a structure-activity study performed on NPS Gly5, the NPSR ligand [D-Cys(tBu)]NPS was identified. [D-Cys(tBu)]NPS up to 100 M did not stimulate calcium mobilization in human embryonic kidney (HEK) 293 cells stably expressing the mouse NPSR; however, in a...
