Trajectory of the spectral/structural rearrangements for photo-oxidative reaction of neat ketoprofen and its cyclodextrin complex
Ketoprofen is a nonsteroidal anti-inflammatory drug used as mohrus tape which causes unwanted photosensitivity due to UV irradiation. In addition, photodegradation of ketoprofen induces its decarboxylation. Here, we aim to determine the effect of cyclodextrin on the photolysis of ketoprofen. Separation technique using HPLC confirmed that UV irradiation of ketoprofen produced multiple products. A unique reaction proceeded in the presence of β-cyclodextrin. Furthermore, characterization by UV spectroscopy was performed, and the obtained spectra were analyzed using singular value decomposition. By analyzing the trajectory of the singular vector space, we were able to reflect the difference in the reaction pathway of ketoprofen with and without cyclodextrin. This study uses a singular value decomposition analysis, which is useful as a novel approach for solutions of radical reactions and a promising technique for analysis of radical reactions in the future.
期刊介绍：
The Journal of Inclusion Phenomena and Macrocyclic Chemistry is the premier interdisciplinary publication reporting on original research into all aspects of host-guest systems. Examples of specific areas of interest are: the preparation and characterization of new hosts and new host-guest systems, especially those involving macrocyclic ligands; crystallographic, spectroscopic, thermodynamic and theoretical studies; applications in chromatography and inclusion polymerization; enzyme modelling; molecular recognition and catalysis by inclusion compounds; intercalates in biological and non-biological systems, cyclodextrin complexes and their applications in the agriculture, flavoring, food and pharmaceutical industries; synthesis, characterization and applications of zeolites.
The journal publishes primarily reports of original research and preliminary communications, provided the latter represent a significant advance in the understanding of inclusion science. Critical reviews dealing with recent advances in the field are a periodic feature of the journal.
