New Study Reveals Insights into Carboxylic Ester Hydrolases with Potential Inhibitors

Strategic Insights -

Research conducted at South Ural State University in Chelyabinsk, Russia, has provided new insights into carboxylic ester hydrolases, enzymes that play a crucial role in various biological processes. The study, published in ChemistrySelect, investigated the conformation of a new imidazole derivative (BMPI) and its potential as an inhibitor of microbial hormone-sensitive lipase-E53. Financial support for the research came from King Saud University.

Key Takeaways:

  • The study revealed that the asymmetric crystal of BMPI consisted of two separate structures with slightly different conformational arrangements of atoms, as investigated using single-crystal X-ray and DFT computations.
  • Electronic skeleton calculations were carried out to explore the electronic, optical, and surface topology of BMPI, which disclosed the presence of hydrogen bonding and van der Waals (vdW) interactions.
  • Orbital analysis and natural population analysis (NPA) were employed to obtain orbital energies and charge transfer phenomena within the structure of BMPI.
  • Ab initio molecular dynamics (AIMD) simulations were used to observe conformational and thermodynamic stability at 298 and 400 K during 1000 femtoseconds.
  • The study concluded that microbial hormone-sensitive lipase-E53 was the best target based on the structure-activity evaluation with molecular dynamics calculations used to recognize the interactions better.
  • Dispersion energy has a significant contribution to total interaction energy for energy framework analysis.
  • Hirshfeld surface analysis unveils the crucial role of H-H and C-H interactions in stabilizing the supramolecular assembly of BMPI.
  • The study has been peer-reviewed and has the potential to contribute to the development of new inhibitors for microbial hormone-sensitive lipase-E53.

Statistics:

  • The study was published in the October 2025 issue (Volume 10, Issue 36) of ChemistrySelect.
  • 1000 femtoseconds of AIMD simulations were conducted to observe conformational and thermodynamic stability of BMPI at 298 and 400 K.
  • The study utilized single-crystal X-ray and DFT computations to investigate the conformation of BMPI.
  • The research team employed orbital analysis and natural population analysis (NPA) to obtain orbital energies and charge transfer phenomena within the structure of BMPI.
  • The study concluded that 16.2% of the total interaction energy was contributed by dispersion energy.
