Description

OFLOXACIN RELATED COMPOUND A (25 MG) ((RS)-9-FLUORO-2,3-DIHYDRO-3-METHYL-7-OXO-10-(PIPERA-ZIN-1 -YL)-7H-PYRIDO[1,2,3-DE]-1,4-BENZOXAZINE-6-CARBOXYLIC ACID) is a metabolite of Ofloxacin, a fluorinated quinolone antibacterial agent. It is characterized by its unique chemical structure, which includes a fluorine atom, a dihydro-dihydroxy-methyl group, a 7-oxo group, and a piperazinyl group attached to a pyrido[1,2,3-de]-1,4-benzoxazine-6-carboxylic acid moiety.

Uses

Used in Pharmaceutical Industry:
OFLOXACIN RELATED COMPOUND A (25 MG) ((RS)-9-FLUORO-2,3-DIHYDRO-3-METHYL-7-OXO-10-(PIPERA-ZIN-1 -YL)-7H-PYRIDO[1,2,3-DE]-1,4-BENZOXAZINE-6-CARBOXYLIC ACID) is used as an impurity in the synthesis and manufacturing process of Ofloxacin, a widely used fluoroquinolone antibiotic. It plays a crucial role in ensuring the quality, safety, and efficacy of the final drug product by serving as a reference compound for quality control and regulatory compliance.
Additionally, as a metabolite of Ofloxacin, it may also be used in research and development for understanding the pharmacokinetics, metabolism, and potential side effects of the parent drug, Ofloxacin. This knowledge can contribute to the optimization of drug formulations, dosing regimens, and the development of new antimicrobial agents with improved safety and efficacy profiles.

Nano-Fe3 O4@ZrO2-SO3 H as highly efficient recyclable catalyst for the green synthesis of fluoroquinolones

Nano-Fe3 O4 @ZrO2-SO3 H (n-FZSA), was utilized as a magnetic catalyst for the synthesis of various fluoroquinolone compounds. These compounds were prepared by the direct amination of 7-halo-6-fluoroquinolone-3-carboxylic acids with piperazine derivatives and (4aR,7aR)-octahydro-1H-pyrrolo[3,4-b] pyridine in water. The results showed that n-FZSA exhibited high catalytic activity towards the synthesis of fluoroquinolone derivatives, giving the desired products in high yields. Furthermore, the catalyst was recyclable and could be used at least seven times without any discernible loss in its catalytic activity. Overall, this new catalytic method for the synthesis of fluoroquinolone derivatives provides rapid access to the desired compounds in refluxing water following a simple work-up procedure, and avoids the use of organic solvents.

Conventional and microwave-assisted synthesis of quinolone carboxylic acid derivatives

Various antibacterial fluoroquinolone compounds are synthesized by the direct amination of 7-halo-6-fluoroquinolone-3-carboxylic acids with a variety of piperazine derivatives and (4aR,7aR)-octahydro-1H-pyrrolo[3,4-b]pyridine using microwave under different reaction conditions. Solvent free high yield microwave synthesis of antibacterial fluoroquinolone compounds is convenient, rapid and environmentally friendly method.
