A document type is Article, introducing its new discovery.

Palmitoylethanolamide (PEA) and oleoylethanolamide (OEA) are endogenous lipid mediators that suppress inflammation. Their actions are terminated by the intracellular cysteine amidase, N-acylethanolamine acid amidase (NAAA). Even though NAAA may offer a new target for anti-inflammatory therapy, the lipid-like structures and reactive warheads of current NAAA inhibitors limit the use of these agents as oral drugs. A series of novel benzothiazole?piperazine derivatives that inhibit NAAA in a potent and selective manner by a non-covalent mechanism are described. A prototype member of this class (8) displays high oral bioavailability, access to the central nervous system (CNS), and strong activity in a mouse model of multiple sclerosis (MS). This compound exemplifies a second generation of non-covalent NAAA inhibitors that may be useful in the treatment of MS and other chronic CNS disorders.

A document type is Article, introducing its new discovery., Recommanded Product: 2,7-Dichlorobenzo[d]thiazole

A convenient synthesis of 2-mercapto and 2-chlorobenzothiazoles is described. The key feature of the synthesis is an exclusive ortho-selective nucleophilic aromatic substitution reaction of ortho-haloanilines with potassium/sodium O-ethyl dithiocarbonate under mild conditions. Subsequent intra-molecular cyclization affords 2-mercaptobenzothiazoles in high yields. The 2-mercaptobenzothiazoles are readily converted to corresponding 2-chlorobenzothiazoles upon treatment with sulfuryl chloride.

Water-Promoted Chlorination of 2-Mercaptobenzothiazoles

Substituted benzothiazoles play an important role in medicinal chemistry due to their pharmacological properties. Their 2-substituted derivatives are often prepared from 2-chlorobenzothiazoles, which in turn can be synthesized from the 2-mercapto precursor using sulfuryl chloride. In practice, this seemingly straightforward and widely used reaction can be impeded by poor reproducibility and low reaction yields. In this communication, we report that the simple addition of water to the reaction leads to remarkable improvements in reaction efficiency. We attribute this effect to the formation of acid through partial hydrolysis of sulfuryl chloride. This hypothesis is supported by the observation that improved yields were also obtained in the presence of some anhydrous acidic additives. The simple combination of sulfuryl chloride and water reproducibly provides excellent yields for a range of chlorinated products.

The synthetic route of 2942-23-6 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.2942-23-6,2,7-Dichlorobenzo[d]thiazole,as a common compound, the synthetic route is as follows.

In a nitrogen atmosphere 2,7-dichlorobenzo[d]thiazole (10.0 g, 49.3mmol) and (9-phenyl-9H-carbazol-3-yl)boronic acid(28.3 g, 98.6 mmol) was added to 300 ml of dioxane, stirred and refluxed. Then potassium carbonate (27.2 g, 197.1 mmol)Was dissolved in 50 ml of water and stirred sufficiently, followed by bis(tri-tertiary-butylphosphine)palladium (1.0 g, 4 mol%) Was added. After the reaction for 12 hours, the temperature was reduced to room temperature, the organic layer and the water layer were separated, and then the organic layer was distilled under reduced pressure.After distillate was extracted with chloroform and water, the organic layer was dried using magnesium sulfate. After drying the organic layer, compound 1 (13.4 g, 44%) was prepared through recrystallization of ethyl acetate., 2942-23-6
