Method for protecting sulfonyl of deamination amine
-
Paragraph 0042-0044, (2021/11/03)
The invention discloses a method for removing sulfenyl protection of amine. The method comprises the following steps: dissolving N - sulfonyl-protected amine and a base in a reaction solvent, then adding diphenylphosphine to uniformly mix and maintain 90 °C. When TCL detection reaction is complete, a recrystallization method or an extraction separation method is adopted to obtain the target product. The method disclosed by the invention adopts diphenylphosphine as an extraction reagent, is good in reaction activity, high in selectivity and wide in application range, and can replace the use of a hazardous reagent under the basic heating condition. Prodrug research and development and industrial production are of great significance.

Sigma 1 receptors are associated with neurodegenerative and psychiatric disorders. These receptors, via their chaperoning functions that counteract endoplasmic reticulum stress and block neurodegeneration, may serve as a target for a new generation of antidepressants or neuroprotective agents. The involvement of these receptors has also been observed in neuropathic pain and cancer. Only a few ligands, such as Igmesine and Anavex 2-73, have been involved in clinical trials. Thus the development of sigma 1 ligands is of interest to a new generation of drugs. Previous work in our lab underlined the potency of benzannulated bicyclic compounds as interesting ligands. Herein the work was extended to a series of novel tricyclic compounds. Carboline- and phenothiazine-derivated compounds were designed and synthesized. In vitro competition binding assays for sigma 1 and 2 receptors showed that most of them have high affinity for sigma 1 receptor (Ki = 2.5-18 nM), and selectivity toward sigma 2 receptor, without cytotoxic effects on SY5Y cells.

Nine novel β2- and 3-carboline derivatives bearing either methyl-, propargyl- or phenethyl-residues at the indole nitrogen were synthesized and tested as potential anti-Alzheimer drugs. Antagonism of recombinantly expressed NMDA receptors, inhibition of cholinesterases, and radical scavenging properties were determined for all compounds. Some were additionally tested in vivo for their ability to reverse scopolamine-induced cognitive impairment in an 8-arm radial maze experiment with rats. For the most promising candidates, the interaction with muscarinic M1receptors was also investigated. With this set of compounds assays the influence of the scaffold itself and the substituents can be investigated separately. 5-Methyl-β3-carboline (6) was the most potent (0.25 1/4mol/100 g b.w.) compound in the in vivo test and might be a good starting point for the development of novel anti-Alzheimer drugs.

Directed screening of nitrile compounds revealed 3 as a highly potent cathepsin K inhibitor but with cathepsin S activity and very poor stability to microsomes. Synthesis of compounds with reduced molecular complexity, such as 7, revealed key SAR and demonstrated that baseline physical properties and in vitro stability were in fact excellent for this series. The tricycle carboline P3 unit was discovered by hypothesis-based design using existing structural information. Optimization using small substituents, knowledge from matched molecular pairs, and control of lipophilicity yielded compounds very close to the desired profile, of which 34 (AZD4996) was selected on the basis of pharmacokinetic profile.

Second-generation Tubastatin A analogues were synthesized and evaluated for their ability to inhibit selectively histone deacetylase 6 (HDAC6). Substitutions to the carboline cap group were well-tolerated with substitution at the 2-position of both β- and γ-carbolines being optimal for HDAC6 activity and selectivity. Some compounds in this series were determined to have subnanomolar activity at HDAC6 with more than 7000 fold selectivity for HDAC6 versus HDAC1. Selected compounds were then evaluated for their ability to augment the immunosuppressive effect of Foxp3+ regulatory T cells. All compounds tested were found to enhance the ability of regulatory T cells to inhibit the mitotic division of effector T cells both in vitro and in vivo, suggesting that further investigation into the use of these compounds for the treatment of autoimmune disorders is warranted.
