Opis:
The purpose of the present work was to assess the ability of five new oxicam analogues to interact with the lipid bilayers. To characterize the interaction of newly synthesized NSAIDs (non-steroidal anti-inflammatory drugs) analogues with DPPC lipid bilayers the two following techniques were applied - differential scanning calorimetry (DSC) and fluorescence spectroscopy. The results obtained by these experimental approaches show that new oxicams analogues interact with the lipid model membranes under consideration. As demonstrated both in calorimetric and spectroscopic studies, the greatest influence on the thermotropic properties of the lipid membrane and on the quenching of fluorescence of Laurdan and Prodan was exerted by a derivative named PR47 containing in its structure a two-carbon aliphatic linker with a carbonyl group, as well as bromine and trifluoromethyl substituents.

Opis:
Oxicams (e.g. piroxicam, meloxicam) are widely used nonsteroidal anti-inflammatory drugs (NSAIDs). A large body of evidence from epidemiological and preclinical studies has shown that NSAIDs have a chemopreventive effect on different types of cancer, especially in colorectal cancer. Moreover, mounting evidence from preclinical and clinical studies suggests that persistent inflammation functions as a driving force in the journey to cancer. What is more, inflammation induces reactive oxygen and nitrogen species, which cause damage to important cellular components (e.g., DNA, proteins and lipids), which can directly or indirectly contribute to malignant cell transformation. In this study, we discuss the synthesis and the resultant newly synthesized oxicam derivatives which are potentially chemopreventive, and at the same time antioxidant. Compound 9c, with the highest therapeutic index in the LoVo cancer cell line, was found to be the most efficient in ROS scavenging activity under conditions of oxidative stress.
