  Discovery of Imidazo[1,5-a]pyrido[3,2-e]pyrazines as a New Class of Phosphodiesterase 10A Inhibitiors

  摘要：

  Novel imidazo[1,5-a]pyrido[3,2-e]pyrazines have been synthesized and characterized as both potent and selective phosphodiesterase 10A (PDE10A) inhibitors. For in vitro characterization, inhibition of PDE10A mediated cAMP hydrolysis was used and a QSAR model was established to analyze substitution effects. The outcome of this analysis was complemented by the crystal structure of PDE10A in complex with compound 49. Qualitatively new interactions between inhibitor and binding site were found, contrasting with previously published crystal structures of papaverine-like inhibitors. In accordance with the known antipsychotic potential of PDE10A inhibitors, MK-801 induced stereotypy and hyperactivity in rats were reversed by selected compounds. Thus, a promising compound class has been identified for the treatment of schizophrenia that could circumvent side effects connected with current therapies.

  The present invention is directed to provide an efficient production method which is capable of not only obtaining a cyclic sulfonic acid ester (sultone) at low cost and in high yield, but also the sulfonic acid ester (sultone) stably even in a commercial scale. The present invention relates to a method for producing hydroxysultone comprising a first step where a diol having a specified structure and a thionyl halide are reacted to obtain a cyclic sulfite having a specified structure, and a second step where the cyclic sulfite is reacted with water or/and alcohol; a method for producing an unsaturated sultone having a specified structure comprising a third step where a hydroxylsultone having a specified structure is reacted with an acid halide or an acid anhydride to obtain an intermediate, subsequently the intermediate is treated with a base; as well as a cyclic sulfite having a specified structure.

  本发明旨在提供一种高效的生产方法，该方法不仅能够以低成本和高产率获得环状磺酸酯（磺酮），而且能够在商业规模下稳定地生产磺酸酯（磺酮）。本发明涉及一种生产羟基磺酮的方法，包括第一步，其中将具有特定结构的二元醇和硫酰卤反应，以获得具有特定结构的环状亚磺酸酯，以及第二步，其中将环状亚磺酸酯与水或/和醇反应；一种生产具有特定结构的不饱和磺酮的方法，包括第三步，其中将具有特定结构的羟基磺酮与酸卤或酸酐反应，以获得中间体，随后用碱处理中间体；以及具有特定结构的环状亚磺酸酯。

  Based on the co-crystal structures of LXR beta and its agonists (spiro [pyrrolidine-3,3'-oxindole] derivatives) discovered by us previously, we designed and synthesized a compound library to explore the agonistic activities. The library was screened with luciferase reporter assays, interestingly, it resulted in the discovery of 10 LXR inverse agonists besides 5 LXR agonists. To clarify the mechanism of the actions, we conducted molecular dynamics (MD) simulations on the LXR and inverse agonists complexes, and revealed that H3, H11 and H12 configurations are the key to turn on agonism or inverse agonism status for LXR. Binding tightly with H3, pushing H11 out and destabilizing H12 could form a bigger hydrophobic groove to accommodate NCOR1 to turn on LXR inverse agonism. The inverse agonist lOrr was further studied, and found as a lipogenesis inhibitor through down-regulating LXR target genes SREBP-1c, ACC, FAS and SCD-1, and demonstrated lipid-lowering effects in 3T3-L1 cells, HepG2 cells and mice with Triton WR-1339-induced hyperlipidemia. Therefore, we have proved that LXR inverse agonists can be promising agents for hyperlipidemia treatment. (C) 2020 Elsevier Masson SAS. All rights reserved.

  5-HT1 receptor antagonists have been discovered with good selectivity over the 5-HT transporter. This is the first report of highly potent, selective ligands for the 5-HT1A/B/D receptors with low intrinsic activity, which represent a useful set of molecules for further understanding the roles of the 5-HT1 receptor subtypes and providing new approaches,for the treatment of depression.
