Urea derivatives are extensively used in the pharmaceutical industry. However, the unsatisfactory level of their membrane penetration requires further modification of the structures with stronger lipophillic properties. Phenylurea has a phenyl group that enables easier membrane penetration as a result of stronger pharmacological activity. Activity prediction was conducted by docking experiments and molecular dynamics, performed with Molegro Virtual Docker 5.5 using checkpoint kinase 1 (CHK1) enzyme with ID PDB: 2YWP. ADMET prediction was applied to collect data using the pkCSM tool. N -(phenyl carbamyol)benzamide compounds, modified by the Schotten Baumann method, were synthesized from benzoil chloride reacting with N -phenylurea. For evaluating anticancer activity, the MTT assay method on HeLa cells was used. Derived from the docking experiments, the compound rerank score of the N -(phenylcarbamoyl)benzamide was 72.0603 kcal/mol, lower than that of hydroxyurea, -32.1514 kcal/mol, causing better inhibitory activities against HeLA cell lines due to higher cytotoxic effects. ADMET Predictor was employed, indicating satisfactory compound distribution with a low, favorable metabolism, possessing good excretion and non-toxicity. The synthesized compound was 82% N- (phenyl carbamoyl)benzamide with 0.8 mM IC 80 , higher than that of hydroxyurea, 4.3 mM. In conclusion, successfully synthesized N- (phenylcarbamoyl)benzamide was proved to have higher cytotoxic effects. The satisfactory values of these compounds indicate that they are promising anticancer drug candidates.
