Abstract

Background

Cervical cancer originates in the cervix, the lower part of the uterus, and results from the uncontrolled growth of abnormal cervical cells, forming malignant tumours. It poses a major global health challenge, calling for innovative drug design strategies to enhance treatment outcomes.

Methods

In this study, we have screened the FDA-approved drug library against four proteins, MCM10, MCM6, DNA polymerase epsilon subunit-2, and TBK1, which are essential for DNA replication, DNA repair, and cellular signalling pathways, which are dysregulated in cervical cancer cells, leading to uncontrolled growth. We have used the multisampling algorithms for screening using HTVS, SP, and XP docking; identified 6-oxidopamine HBr (CHBrNO), which is used to create a model of Parkinson’s disease in animals, and obtained the docking score ranging from -5.057 to -8.871 Kcal/mol. The poses were filtered with MM\GBSA score ranging from -21.67 to -27.63 Kcal/mol. We performed QM-based DFT and pharmacokinetics studies and compared them with the standard values, suggesting that the compound can be used in cervical cancer proteins.

Results

The P-L complex’s interaction fingerprints have resulted in the most interacting residues, 4THR, 4SER, and 4LYS, showing the compound’s interaction pattern.

Conclusion

Further, the stability of 6-oxidopamine HBr in complex with each protein was evaluated with 100 ns MD simulation in the SPC water model in a neutralised state to analyse the deviation, fluctuations, and intermolecular interactions that have proven the compound to have a better inhibitory effect against each protein and that it can be used for cervical cancer; however, experimental validation is suggested before human use.
