Pharmacofor Modeling Study of Compounds that have the potential to be inhibitors parp

Introduction

Ovarian cancer is a malignant disease that attacks many women after menopause in Indonesia. The use of parp inhibitors is one of the therapeutic choices that are often used, but face the resistance constraints that often arise. This study aims to identify compounds that have the potential to be inhibitors of parp through pharmacofor modeling studies and test the results of identification based on lipinski rules, physicochemical properties parameters, and molecular docking.

Understanding Parp Inhibitors

Parp inhibitors are a class of drugs that have been shown to be effective in treating certain types of cancer, including ovarian cancer. These inhibitors work by blocking the activity of the parp enzyme, which is involved in the repair of DNA damage. By blocking this enzyme, parp inhibitors can help to prevent the growth and spread of cancer cells. However, the use of parp inhibitors is not without its challenges. One of the major limitations of these drugs is the development of resistance, which can limit their effectiveness.

Pharmacofor Modeling Study

Pharmacofor modeling is a computational approach that is used to identify potential lead compounds for drug development. This approach involves the use of computational models to predict the binding affinity of a compound to a specific protein target. In this study, pharmacofor modeling was carried out using ligandsout software, virtual filtering was carried out through a pharmit website, lipinski rules testing was carried out through the Swissadme website, molecular docking was carried out using autodock vina, and visualization of amino acid residues was carried out using Biovia Discovery Studio.

Results

The results of this study showed that based on the assessment of each ligand obtained from pharmacofor modeling and virtual filtering studies of Parp receptors (GDP code: 6NRJ), the compounds found were Zinc000012895188, Zinc000408664724, Zinc000197728633, Zinc000057895413, Zinc000408670550, Zinc 000299759100, Zinc000040156126, and Zinc000009046885.

Visualization of Amino Acid Residue Interactions

In visualization of amino acid residue interactions, zinc000012895188 compounds, zinc000057895413, zinc000040156126, and zinc000299817270 were found to have the potential to act as inhibitors parp. This is proven through the calculation of in silico through lower Gibbs (∆G) free energy in the tested ligands and the interaction of amino acid residues from the ligands that are tested similar to the comparison ligand, talazoparib.

Conclusion

This study opens opportunities for the development of new drugs based on parp inhibitors with higher effectiveness and lower resistance. Further development needs to be done through in vitro and in vivo tests to validate the results of this pharmacopho-modeling study and ensure the safety and effectiveness of these compounds as prospective parp inhibitors.

Future Directions

The results of this study suggest that pharmacofor modeling can be a useful tool in the identification of potential lead compounds for drug development. However, further studies are needed to validate the results of this study and to ensure the safety and effectiveness of these compounds as prospective parp inhibitors. In vitro and in vivo tests will be necessary to confirm the results of this study and to determine the potential of these compounds as therapeutic agents.

Limitations

One of the limitations of this study is the use of computational models to predict the binding affinity of compounds to a specific protein target. While these models can be useful in identifying potential lead compounds, they are not without their limitations. The accuracy of these models can be affected by a number of factors, including the quality of the data used to train the model and the complexity of the protein target.

Conclusion

In conclusion, this study demonstrates the potential of pharmacofor modeling in the identification of potential lead compounds for drug development. The results of this study suggest that zinc000012895188 compounds, zinc000057895413, zinc000040156126, and zinc000299817270 have the potential to act as inhibitors parp. Further studies are needed to validate the results of this study and to ensure the safety and effectiveness of these compounds as prospective parp inhibitors.

Recommendations

Based on the results of this study, the following recommendations are made:

Further studies should be conducted to validate the results of this study and to ensure the safety and effectiveness of these compounds as prospective parp inhibitors.
In vitro and in vivo tests should be conducted to confirm the results of this study and to determine the potential of these compounds as therapeutic agents.
The use of pharmacofor modeling should be further explored as a tool in the identification of potential lead compounds for drug development.
