Cas no 22161-81-5 (S-(+)-Ketoprofen)

S-(+)-Ketoprofen is the pharmacologically active enantiomer of ketoprofen, a nonsteroidal anti-inflammatory drug (NSAID) belonging to the arylpropionic acid class. As the dextrorotatory form, it exhibits superior potency compared to the racemic mixture, with enhanced selectivity for cyclooxygenase (COX) inhibition. This results in improved anti-inflammatory, analgesic, and antipyretic effects at lower doses, reducing the risk of adverse gastrointestinal and renal effects. S-(+)-Ketoprofen is widely utilized in pharmaceutical research and development due to its high enantiomeric purity and well-characterized pharmacokinetic profile. Its chiral specificity makes it valuable for studying stereoselective drug metabolism and optimizing therapeutic efficacy in clinical applications.

Additional information on S-(+)-Ketoprofen

Introduction to S-(+)-Ketoprofen and CAS No 22161-81-5

S-(+)-Ketoprofen, identified by the chemical compound CAS No 22161-81-5, is a highly enantiomerically pure form of the well-known nonsteroidal anti-inflammatory drug (NSAID) ketoprofen. This compound has garnered significant attention in the pharmaceutical and biochemical research communities due to its enhanced pharmacological properties compared to the racemic mixture. The focus on S-(+)-Ketoprofen stems from its superior efficacy, reduced side effects, and improved patient tolerance, making it a promising candidate for therapeutic applications.

The stereochemical purity of S-(+)-Ketoprofen is a critical factor in its pharmacological profile. Unlike the racemic mixture of ketoprofen, which contains both the S-(+)-enantiomer and its inactive R-(-)-enantiomer, the enantiomerically pure form exhibits more predictable and potent biological activity. This distinction has been extensively studied in recent years, with researchers uncovering novel mechanisms of action that contribute to its therapeutic benefits.

Recent advancements in chiral synthesis have enabled the efficient production of S-(+)-Ketoprofen, making it more accessible for clinical and research purposes. These innovations have not only improved the scalability of production but also reduced costs, paving the way for broader adoption in pharmaceutical formulations. The compound's stability under various storage conditions further enhances its practicality for medical use.

In clinical settings, S-(+)-Ketoprofen has been investigated for its potential in managing a range of inflammatory and pain-related conditions. Studies have demonstrated its efficacy in reducing pain and inflammation with a lower incidence of gastrointestinal side effects compared to traditional NSAIDs. This makes it an attractive option for patients who may be sensitive to conventional treatments.

The pharmacokinetic profile of S-(+)-Ketoprofen is another area of active research. Unlike racemic ketoprofen, which exhibits a relatively short half-life, S-(+)-Ketoprofen demonstrates prolonged bioavailability and sustained therapeutic effects. This extended duration of action can lead to fewer dosing requirements, improving patient compliance and convenience.

One of the most compelling aspects of S-(+)-Ketoprofen is its potential in personalized medicine. By leveraging advances in genetic testing and biomarker analysis, researchers are exploring how individual patient responses to this compound can be optimized. This approach holds promise for tailoring therapeutic regimens to maximize efficacy while minimizing adverse effects.

The biochemical interactions of S-(+)-Ketoprofen have also been a subject of intense study. Researchers have identified specific enzymes and receptors targeted by this enantiomer, providing insights into its mechanism of action. These findings not only enhance our understanding of the compound's pharmacology but also open avenues for developing novel drug candidates that mimic or enhance its effects.

Moreover, the environmental impact of producing and disposing of pharmaceutical compounds has led to investigations into sustainable practices for synthesizing S-(+)-Ketoprofen. Green chemistry principles are being applied to develop more eco-friendly synthetic routes, reducing waste and energy consumption without compromising yield or purity.

The regulatory landscape for S-(+)-Ketoprofen is evolving as its benefits become more widely recognized. Regulatory agencies are increasingly considering enantiomerically pure drugs as distinct entities from their racemic counterparts, necessitating updated guidelines for approval and labeling. This shift reflects a growing understanding of the importance of stereochemistry in drug development.

In conclusion, S-(+)-Ketoprofen (CAS No 22161-81-5) represents a significant advancement in NSAID therapy due to its superior pharmacological properties and reduced side effects. Ongoing research continues to uncover new applications and refine production methods, ensuring that this compound remains at the forefront of pharmaceutical innovation. As our understanding of stereochemistry deepens, compounds like S-(+)-Ketoprofen will likely play an increasingly vital role in addressing complex medical challenges.
