| Summary: | Introduction: Cholera is a highly contagious disease that causes severe
diarrhea and dehydration. This study investigated podophyllotoxin,
deoxypodophyllotoxin, and ursolic acid as inhibitors of tcpA, ompW, and ctxB
genes in Vibrio cholerae. Methods: We obtained the crystallized structure of
podophyllotoxin, deoxypodophyllotoxin, and ursolic acid from the PubChem
database for use as a ligand. The mm2 method in Chem3D v20.1.1.125 was
used to optimize the structure of the ligands. We used AutodackVina v.1.2.0
to evaluate the ligands as inhibitors against the active site of the tcpA, ompW,
and ctxB proteins. The output results were analyzed and assessed by BIOVIA
Discovery Studio 2016 V16.1.0 X64. Results: The reported affinities ranged
from -6.8 and -8.7 kcal/mol. The highest diversity of links was found in tcpA
and ctxB. Hydrogen bonds were established with Threonine (91, 111), Glycine
(113, 114, 94), and Alanine (92) of tcpA, indicating the effectiveness of
ligands against tcpA. The ligands podophyllotoxin, deoxypodophyllotoxin,
and ursolic acid showed a variety of hydrogen bonds against ompW and ctxB,
respectively, with Arginine, Isoleucine, Histidine, Glycine, and Glutamine.
These results demonstrate the excellent inhibitory effects of the ligands against
Vibrio cholerae. Conclusion: Vibrio cholerae plays a crucial role in causing
pandemic cholera in humans. The predicted conformations of the ligands in
this study showed that podophyllotoxin and deoxypodophyllotoxin have
higher inhibitory potential than ursolic acid. Therefore, podophyllotoxin and
deoxypodophyllotoxin can be potential agents for further research in
developing Anti-Vibrio cholerae drugs. |
