Physicochemical, ADMET Properties, and Molecular Docking Studies of N-Benzoyl-N’-Naphtylthiourea Derivatives for Anti-Breast Cancer Activity

Abstract

Background: N-benzoyl-N'-naphthylthiourea (BNTU) is a thiourea-derived compound that is predicted to have anti-breast cancer activity. However, their physicochemical properties, ADMET, and receptor-specific targets for their anti-breast cancer activity have not been reported. Objective: This study aimed to predict the physicochemical properties, ADMET, and anti-breast cancer activity of BNTU and its derivatives by in silico approach. Methods: The physicochemical and ADMET properties were predicted using the pkCSM online program and ProTox-II online tool. While the anti-breast cancer activity was predicted using the molecular docking method through the Molegro Virtual Docker (MVD) program on the HER-2 receptor. The parameter observed in the molecular docking method was the bond energy value or rerank score (RS). Compounds with small RS values were predicted to have a great activity. Results: Most BNTU derivatives had lower RS values than BNTU, especially 4TBBNTU, and 4CFBNTU, although their RS values were still higher than lapatinib and TAK-285. As for the reference ligand hydroxyurea, the RS value of BNTU and its derivatives was much lower. The physicochemical and pharmacokinetic properties (ADMET) of lapatinib and TAK-285 were not better than that of BNTU and its derivatives. Conclusion: Five compounds that deserve to be synthesized and tested for anti-breast cancer activity in vitro and in vivo are 4TBBNTU, 3CFBNTU, 4CFBNTU, 4OCBNTU, and the lead compound
