The binding of low mol. weight compounds with the transport proteins of blood is an essential step of their delivery into living cells and thus the accurate investigation of the interactions occurring in solution at physiol. conditions is crucial for the development of efficient biol. active mols. In this work, we report on the complex species, stability constants and thermodn. parameters for the binding reactions of hydrazones derived from pyridoxal-5鈥?phosphate (PLP) with bovine and human serum albumin (BSA and HSA) in neutral aqueous solution The study has been carried out using isothermal titration calorimetry which allowed to directly obtain both binding constant and enthalpy change values for the systems investigated. The thermodn. characterization in solution revealed that the PLP-hydrazone derivatives are able to effectively interact with both bovine and human serum albumin and enabled the determination of the driving forces for the mol. recognition process. The formation of the 1:1 complex was found to be always enthalpy favored and driven due to the insertion of the hydrazone moieties into the hydrophobic pockets of BSA or HSA. This study involved multiple reactions and reactants, such as (4-Formyl-5-hydroxy-6-methylpyridin-3-yl)methyl dihydrogen phosphate (cas: 54-47-7Recommanded Product: (4-Formyl-5-hydroxy-6-methylpyridin-3-yl)methyl dihydrogen phosphate).
(4-Formyl-5-hydroxy-6-methylpyridin-3-yl)methyl dihydrogen phosphate (cas: 54-47-7) belongs to pyridine derivatives. Pyridine is diamagnetic and has a diamagnetic susceptibility of 鈭?8.7 脳 10鈭? cm3路mol鈭?.The molecular electric dipole moment is 2.2 debyes. The standard enthalpy of formation is 100.2 kJ路mol鈭? in the liquid phase and 140.4 kJ路mol鈭? in the gas phase. Reduced pyridines, namely tetrahydropyridines, dihydropyridines and piperidines, are found in numerous natural and synthetic compounds. The synthesis and reactivity of these compounds have often been driven by the fact many of these compounds have interesting and unique pharmacological properties.
