The role of oxazolidine derivatives in the treatment of infectious and chronic diseases

Background: Despite being known for their antibacterial activity, the oxazolidines are molecules with wide pharmacological action and may act as anticonvulsants, anti-inflammatory and antineoplasic agents. However, such activities have been poorly explored and only two oxazolidinic derivatives hit the market until now. Therefore, this review covers the main biological activities of oxazolidines, indicating which of the classes and substituents have the best biological results as well as the synthesis methodology used to obtain them. Methods: The search for bibliographic data was made using a question focused on the oxazolidine structure and their respective activities, besides using inclusion/exclusion criteria clearly defined. The selected papers were subjected to qualitative content analysis methodology to be used in this review. Results: The oxazolidines remain excellent candidates for antibacterial, presenting three compounds in clinical testing phase (Radezolide, Cadezolide and Sutezolide), besides being a good candidate as antitubercular agents. Other less explored activities have niches with a great therapeutic potential such as the oxazolidines acting on 5-HT receptors (anticonvulsant) and Zolmitriptan (anti-migraine), and also mefloquine-oxazolidine derivatives which may act as antineoplasic and antitubercular agents. Conclusion: This review summarizes the versatility and great therapeutic potential that oxazolidines can offer, reinforcing the need for further studies and investments for this class of molecules.

Electrolytic partial fluorination of organic compounds. Part 78: Regioselective anodic fluorination of 2-oxazolidinones

Various 2-oxazolidinones were galvanostatically electrooxidized in the presence of various fluoride salts. It was found that a fluorine atom was introduced to the alpha-position of the nitrogen atom of N-acyl- and N-alkoxycarbonyl-2-oxazolidinones to provide the corresponding alpha-fluorinated products in moderate to good yields. In the case of N-phenoxycarbonyl derivative, fluorination took place on the phenyl group selectively.

SAR, pharmacokinetics, safety, and efficacy of glucokinase activating 2-(4-sulfonylphenyl)-N-thiazol-2-ylacetamides: Discovery of PSN-GK1

Allosteric activators of the glucose-sensing enzyme glucokinase (GK) are currently attracting much interest as potential antidiabetic therapies because they can achieve powerful blood glucose lowering through actions in multiple organs. Here, the optimization of a weakly active high-throughput screening hit to (2R)-2-(4-cyclopropanesulfonylphenyl)-N-(5-fluorothiazol-2-yl)-3- (tetrahydropyran-4-yl)propionamide (PSN-GK1), a potent GK activator with an improved pharmacokinetic and safety profile, is described. Following oral administration, this compound elicited robust glucose lowering in rats.

Copper-catalyzed amination of aryl and alkenyl electrophiles

The copper-catalyzed arylation and vinylation of nitrogen nucleophiles is a highly versatile method for the construction of sp2C?N bonds. Copper-catalyzed C?N bond formation has an extensive history and the field has been reinvigorated with the development of ligand-promoted catalyst systems that provide general and effective reactions under relatively mild conditions. Copper promotes arylation and vinylation of a wide range of nitrogen nucleophiles, including amines, nitrogen heterocycles, and amide derivatives. The reactivity profile is complementary to that of palladium and often offers orthogonal chemoselectivity. This chapter presents a thorough overview of the copper-catalyzed coupling of aryl and vinyl halides with nitrogen nucleophiles. Current understanding of the mechanism of this process is presented along with a detailed overview of the scope and limitations of this reaction along with optimal reaction conditions for the coupling of various nitrogen nucleophile classes.
