Breast Cancer is foremost common type in worldwide and major risk of death in women. SR9009 a pyrrole derivatives and synthetic role of the REV-ERB alpha, core of circadian clock components. Hence it is interest to document the molecular docking analysis of SR9009 with different breast cancer target protein targets such as HER2, Erα, PR, PI3K, AKT, Reverbα, BRMS1, Aromatase and mTOR, CDK4, CDK6, TK and Top II. Among 13 proteins, HER2, Erα, Aromatase, Reverbα, BRMS1 and Top II have good binding score affinity. Molecular Dynamic results show that significant higher binding energy for Reverb alpha + SR9009 complex found to be -220.618 +/- 19.145 kJ/mol compared to Reverb alpha + Doxorubicin complex found to be -154.812 +/- 18.235 kJ/mol. Molecular docking and dynamics analysis show that SR9009 is a potential drug candidate targeting Reverb alpha for anti-breast cancer activity.
