Discovery of a tetracyclic quinoxaline derivative as a potent and orally active multifunctional drug candidate for the treatment of neuropsychiatric and neurological disorders

We report the synthesis and structure-activity relationships of a class of tetracyclic butyrophenones that exhibit potent binding affinities to serotonin 5-HT2A and dopamine D2 receptors. This work has led to the discovery of 4-((6bR,10aS)-3-methyl-2,3,6b,9,10,10a-hexahydro-1H,7H- pyrido[3?,4?:4,5]pyrrolo[1,2,3-de]quinoxalin-8-yl) -1-(4-fluorophenyl)-butan-1-one 4-methylbenzenesulfonate (ITI-007), which is a potent 5-HT2A antagonist, postsynaptic D2 antagonist, and inhibitor of serotonin transporter. This multifunctional drug candidate is orally bioavailable and exhibits good antipsychotic efficacy in vivo. Currently, this investigational new drug is under clinical development for the treatment of neuropsychiatric and neurological disorders.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 3080-99-7, help many people in the next few years.3080-99-7

A balanced equation for a chemical reaction indicates what is reacting and what is produced, but it reveals nothing about how the reaction actually takes place. The reaction mechanism is the process, or pathway, by which a reaction occurs.3080-99-7, name is :3,4-Dihydro-2H-benzo[b][1,4]thiazine. An updated downstream synthesis route of 3080-99-7 as follows.3080-99-7

(3d) Potassium carbonate (5.2 g, 37.7 mmol) and methyl 4-(bromomethyl)benzoate (2.8 g, 12.6 mmol) were added to a solution of (3c) (1.9 g, 12.6 mmol) in 20 mL of anhydrous DMF. The reaction mixture was heated to 80 C. overnight. After cooling to rt, the solid was filtered off and rinsed with DMF. The filtrate was concentrated in vacuo and the residue was purified on silica gel column to provide methyl 4-(2,3-dihydro-4H-1,4-benzothiazin-4-ylmethyl)benzoate (3.02 g, 80%).

This compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,3080-99-7,3,4-Dihydro-2H-benzo[b][1,4]thiazine,its application will become more common.

A heterogeneous catalyst is a catalyst that is present in a different phase than the reactants. Such catalysts generally function by furnishing an active surface upon which a reaction can occur. 3080-99-7, name is :3,4-Dihydro-2H-benzo[b][1,4]thiazine, introduce a new downstream synthesis route as follows. 3080-99-7
