Comprehensive Spectroscopic, Computational, and Pharmacokinetic Characterization of the Cardiovascular Drug- Bisoprolol.

INTRODUCTION The introduction outlines the bisoprolol study aimed at elucidating its molecular structure, physicochemical properties, and biological activity using several combined analytical techniques, including spectroscopy, computational modeling, and pharmacokinetics.

Methods

Structural features were determined via FT-IR, Raman, and NMR spectroscopy. Optimized geometry, molecular stability, and frontier molecular orbital (FMO) properties were determined using density functional theory (DFT). Molecular docking studies and ADME analysis were conducted with the hydrolase enzyme (4W71) and an IgG-like protein (4PR5), following Lipinski's rules for drug-like properties.

Results

In spectroscopy, the presence of hydroxyl, amine, aromatic, and carbonyl groups was confirmed. In DFT, intramolecular hydrogen bonding, with appropriate bond parameters, was observed, with a HOMO-LUMO gap (6.32 eV) indicating potential π-π* and n-π* transitions. The interactions observed during docking showed stable binding with the hydrolase (-7.21 kcal/mol) and immune-related protein targets (-5.64 kcal/mol). ADME characteristics were also reviewed for compliance with Lipinski's Rule of Five.

Discussion

Overall, the spectroscopic, computational modeling, and pharmacokinetic data are consistent with one another and provide insight into the structural integrity, electronic properties, and biological activity of bisoprolol.

Conclusion

Based on the in silico molecular docking investigations and ADME predictions, it is reasonable to conclude that the metabolic pathways of bisoprolol and its interactions with biological systems are highly likely to be consistent with the available literature.
