Either a solution-based or a superior solvent-free mechanochem. protocol can be followed. X-Ray diffraction analyses of 26 products provided insight into the bond parameters and conformational rigidity of the mol. scaffold. In solid-state structures, sulfoximines with halo substituents on the S-bound arene are intermolecularly linked by C-X¡¤¡¤¡¤O=S (X = Cl, Br) halogen bonds. Hirshfeld surface anal. is used to assess the type of non-covalent contacts present in mols. For mixtures of three different S-pyridyl-substituted NTFP-sulfoximines and N-iodosuccinimide (NIS) in CDCl3, association constants were determined by 1H NMR spectroscopy. The data revealed a dependence of the halogen bond strength on the position of the pyridyl nitrogen indicating the presence of N-I¡¤¡¤¡¤N(S-pyridyl) interactions.

Tolerance development caused by dopamine replacement with L-DOPA and therapeutic drawbacks upon activation of dopaminergic receptors with orthosteric agonists reveal a significant unmet need for safe and effective treatment of Parkinson’s disease. In search for selective modulators of the D1 receptor, the screening of a chem. library and subsequent medicinal chem. program around an identified hit resulted in new synthetic compound 26 [UCM-1306, 2-(fluoromethoxy)-4′-(S-methanesulfonimidoyl)-1,1′-biphenyl] (I) that increases the dopamine maximal effect in a dose-dependent manner in human and mouse D1 receptors, is inactive in the absence of dopamine, modulates dopamine affinity for the receptor, exhibits subtype selectivity, and displays low binding competition with orthosteric ligands. The new allosteric modulator potentiates cocaine-induced locomotion and enhances L-DOPA recovery of decreased locomotor activity in reserpinized mice after oral administration. The behavior of compound 26 supports the interest of a pos. allosteric modulator of the D1 receptor as a promising therapeutic approach for Parkinson’s disease.
