Background Crizotinib and Temozolomide are the two major chemotherapy drugs used for the treatment of cancers. Crizotinib is used as a target chemotherapy drug in many cancers. It mainly binds on the ATP binding regions of receptor tyrosine kinases (RTKs) targets and inhibits protein phosphorylation, which has already been reported. Temozolomide drug is known as the alkylating agent. Its mechanism of action is the methylation of DNA and thereby inhibiting DNA replication. However, the Temozolomide drug with protein level interaction of Glioblastoma Multiforme (GBM) and Non-small-cell lung carcinoma (NSCLC) of RTKs targets has not been reported so far. In the proposed work, we investigated the molecular level interaction of the Temozolomide drug in C-MET, C-ROS1, and ALK RTKs targets of GBM and NSCLC using an in silico study. We performed comparative analysis studies in both drugs' docked complexes based on their drug properties and complex energy (CE) to identify the better efficacy of the drug. Results From the docking studies, we could identify that the Temozolomide drug bounded protein complexes showed the least complex energy. The most stable complexes were identified from these docking studies by Molecular Dynamic simulation. In the proposed study, we found that the docked complex attained a stable conformation and least energy via solid hydrogen bond interactions between the amino acid residues and the drug at the binding sites of the proteins. The least energy and the hydrogen bond interaction of Temozolomide drug with the amino acid residues of the protein complexes of C-MET, C-ROS1 and ALK protein with their id name are: 2WGJ is − 11305.0830 (PRO1158, MET1160), 3ZBF is − 11,659.6814 (MET2029, GLU2027), and 2XP2 is − 11,734.7565 (ARG1275, ASP 1160, GLU1167). Conclusion Our studies revealed that the Temozolomide drug bounded protein complex showed the least energy when compared to Crizotinib. So it will give better interaction on the binding sites of proteins and thereby provide better inhibition in the treatment of target therapy of GBM and NSCLC.
