  N′-(Arylsulfonyl)pyrazoline-1-carboxamidines as Novel, Neutral 5-Hydroxytryptamine 6 Receptor (5-HT₆R) Antagonists with Unique Structural Features

  摘要：

  The 5-HT6 receptor (5-HT6R) has been in the spotlight for several years regarding CNS-related diseases. We set out to discover novel, neutral 5-HT6R antagonists to improve off-target selectivity compared to basic amine-containing scaffolds dominating the field. High-throughput screening identified the N'-(sulfonyl)pyrazoline-1-carboxamidine scaffold as a promising neutral core for starting hit-to-lead. Medicinal chemistry, molecular modeling, small molecule NMR and X-ray crystallography were subsequently applied to optimize the leads into antagonists (compounds 1-49) displaying high 5-HT6R affinity with optimal off-target selectivity. Unique structural features include a pseudoaromatic system and an internal hydrogen bond freezing the bioactive conformation. While physicochemical properties and CNS availability were generally favorable, significant efforts had to be made to improve metabolic stability. The optimized structure 42 is an extremely selective, hERG-free, high-affinity 5-HT6R antagonist showing good human in vitro metabolic stability. Rat pharrnacokinetic data were sufficiently good to enable further in vivo profiling.

  2-dimethyl substituents in the backbone (ArCH==NCH(2)CMe(2)CH(2)N==CHAr), whereas tBuMe(2)Si substituents at the 3-positions of the salicylidene moieties lead to the highest selectivity (P(meso)=0.9(8); T(m)=210 degrees C). The ratio of the rate constants in the ROPs of racemic lactide and L-lactide is found to correlate with the stereoselectivity in the present system. The complex can be utilized in bulk

  A transamination process is described to prepare polyamine product mixtures from reactants comprising mixed nitrogen-containing compounds with binary carbon spacing between nitrogen-containing groups (a binary component). A second nitrogen-containing component with a second carbon atom spacing between nitrogen-containing groups may also be employed. The molar ratio between the binary and second components can be adjusted to customize the product composition for desired end uses.
