Article Synopsis
  • The study investigates how leflunomide (LEF), an anticancer drug, binds to human serum albumin (HSA), a major protein in blood circulation, using various biophysical and computational techniques.
  • Findings showed that LEF interacts with HSA through static quenching mechanisms, with moderate binding strength influenced by hydrophobic interactions and hydrogen bonds, suggesting that LEF stabilizes HSA's structure against temperature changes.
  • Molecular docking and dynamics simulations indicated that LEF preferentially binds to Sudlow's site I on HSA, maintaining a stable complex throughout the simulations.

Interactive association of an antifungal drug, climbazole (CBZ) with the carrier protein in bovine circulation, bovine serum albumin (BSA) was explored by fluorescence and absorption spectroscopy along with in silico techniques. The fluorescence and absorption spectral alterations of the protein upon addition of CBZ affirmed the complex foration between CBZ and BSA. The inverse temperature dependence behaviour of the K values as well as the hyperchromic result of the protein's absorption signals characterized CBZ-triggered quenching of BSA fluorescence as the static quenching.

Interaction of two broadly used herbicides, aclonifen (ACF) and bifenox (BIF) with the major transporter in human circulation, human serum albumin (HSA) were examined using fluorescence and absorption spectral measurements combined with in silico analyses. Assessment of the fluorescence and absorption spectral results affirmed the complexation between ACF/BIF and HSA. Increase in the K value with temperature characterized the ACF/BIF-induced quenching of the protein fluorescence as dynamic quenching.
