Herein, the influence of polar protic solvents (water and ethanol) and aprotic solvents (acetone and DMSO) on the properties of 3-(dimethylaminomethyl)-5-nitroindole (DAMNI) was investigated using density functional theory (DFT) computations. Thermodynamic parameters retrieved from the vibrational analysis indicated that the DAMNI\u2019s entropy, heat capacity, and enthalpy increased with rising temperature. Natural bond orbital computations elucidated the non-bonded interactions of DAMNI. DAMNI demonstrated promising nonlinear optical properties and chemical reactivity in water, with DMSO being the second most effective solvent. Frontier molecular orbitals and global descriptors confirmed the impact of solvents on intermolecular charge transfer. The docking estimations were conducted to predict the docking pose of DAMNI against ER<jats:italic>\u03b1<\/jats:italic> and EGFR, both of which are acknowledged for their significance in breast cancer treatment. Upon the docking outcomes, DAMNI revealed superior binding affinity against ER<jats:italic>\u03b1<\/jats:italic> (calc. \u20135.8 kcal\/mol), in comparison with DAMNI against EGFR (calc. \u20134.7 kcal\/mol). Eventually, molecular dynamics simulations (MDS) were carried out, followed by a binding energy computation utilizing the MM\/GBSA approach. Upon the MM\/GBSA\/\/150 ns MDS, the DAMNI-ER<jats:italic>\u03b1<\/jats:italic> complex revealed lower binding energy than DAMNI-EGFR, with \u0394<jats:italic><jats:italic>G<\/jats:italic><\/jats:italic><jats:sub>binding<\/jats:sub> values of \u221221.1 and \u221215.4 kcal\/mol, respectively.
