The product of fusion gene gives rise to EWSR1/FLI1 which activates the activity of Eyes absent homolog 3 (EYA3) which causes tumor growth and angiogenesis. EYA3 is now considered as a therapeutic drug target for EWS . The study was designed to gather potential inhibitors for the EYA3 target using medicinal compounds. Methods: In this study, we have obtained a list of medicinal compounds from the NuBBE database and downloaded their structural information. Then insilico screening analysis of >2,000 medicinal compounds was performed with PyRX virtual drug screening software to discover potential inhibitors for the treatment of EWS. Results: Our investigation revealed that Sorbifolin and 1,7-Dihydroxy-3-methylanthracene-9.10-dione show interactive affinity for EYA3 active residues. Moreover, these compounds have adequate toxicity, can induce cytotoxicity in EWS cells, and are capable of regulating the expression of genes activated by EWSR1/FLI1. Conclusion: Our study concluded that Sorbifolin and 1,7-Dihydroxy-3-methylanthracene-9.10-dione are promising drug candidates for the treatment of EWS and should be further subjected to invitro testing. }, keywords = {Eyes Absent Homolog-3,Ewing sarcoma,Virtual screening,Medicinal Compounds,In silico Gene expression}, url = {https://journal.waocp.org/article_90102.html}, eprint = {https://journal.waocp.org/article_90102_c419bf7db5afeb2c7c9db3117977fb30.pdf} }
