Molecular Docking and Admet Prediction of 5-Benzyloxytryptophan as a Potential Radiopharmaceutical Kit for Molecular Imaging of Cancer

Abstract

Objective: This in silico study aims to determine the inhibition effect of 5-BOTP with various bifunctional chelating agents (BFCA); NOTA, DOTA, TETA, CTPA, H2CB-DO2A, H2CBTE2A against the antiporter site of the LAT1.
 Methods: The research method consisted of the binding mode of 5-BOTP and its derivatives with LAT1, the docking score, the analysis of preADMET, and the overview of Ro5 compatibility.
 Results: The results showed that 5-BOTP-NOTA and 5-BOTP-DOTA had interactions with the gating residue (Phe252, Trp257, Asn258, and Tyr259) on the antiporter site of LAT1. 5-BOTP-NOTA and 5-BOTP-DOTA affinity are around-11.50 and-9.14 kcal/mol, respectively.
 Conclusion: Based on this study, 5-BOTP-NOTA and 5-BOTP-DOTA are the new compounds that have the potential as a theranostic agent of cancer by inhibiting LAT1.
