Protective role of benzoselenophene derivatives of resveratrol on the induced oxidative stress in intestinal myofibroblasts and osteocytes

Resveratrol (RE), a polyphenolic compound present in some food and plants, is characterized by anti-inflammatory and antioxidant properties. However, it is quickly metabolized with consequent loss of its efficacy. In this study, the antioxidant effect of 2-phenyl-benzoselenophene derivatives (VD0, VD1 and VD2) was detected in intestinal myofibroblast and osteocyte cell lines in which the oxidative stress was induced by GSH depletion or starvation, respectively. In fact, the oxidative stress is involved in pathogenesis of inflammatory bowel diseases (IBD) and in increased osteoclastogenesis in osteoporosis. Our results show that these derivatives have major antioxidant power in reducing and/or restoring radical oxygen species to control values than RE itself in both cell types. Moreover, derivatives have different antioxidant capacity in myofibroblasts and in osteocytes and this can be due to different degree of oxidative stress and structural characteristics of these compounds. Some of the synthesized RE analogs have shown anti-bacterial role in IBD and anti-resorptive activity in bone pathologies related to inflammatory and osteoporotic processes. Thus, we suggest benzoselenophene derivatives as good candidates for alternative therapy and/or therapeutic support in these pathologies.
