This study examined the antiangiogenic capacity of diosmin in vitro and their interactions with certain important receptors related to cancer and infectious diseases via molecular docking. Diosmin, a naturally occurring flavone glycoside, largely found in citrus fruits, exhibits potentially antiangiogenic properties especially interacting with both VEGF and VEGFR. Treatment with certain doses of diosmin caused a reduction with a ratio of 22–68% on VEGF levels as compared to non-treated control groups. Western blotting and real-time PCR results demonstrated that protein expression of VEGF was downregulated in a dose- and time-dependent manner. On the other hand, we aimed to check the possible interaction of diosmin with VEGF, VEGFR, HER, PR, ER, and Omp-a, receptor proteins. According to our molecular docking results, diosmin effectively binds these receptors and probably this could be one of the possible reasons for its anti-angiogenic and anti-microbial properties.
