“…The resolution of the protein-warfarin complexes is not high enough to identify the presence or absence of protons. It is assumed, though, that warfarin is also in the ionic deprotonated form in such complexes based on a pK a value around 5 [15]. S-Warfarin is seen in complex with P450, but both R-and S-warfarin are found to be consistent with the electron densities for warfarin in complex with HSA [5,6].…”

“…The open side chain form involves the tautomers shown in Scheme 1 that differ in the protonation of the oxygens at the 2 and 4 positions. In aqueous solvent at physiological pH, it is assumed that the deprotonated anionic species is dominant with a pK a value of 5.1 [15] while the 2-hydroxyl or 4-hydroxyl forms would become relevant under low-pH conditions or in environments that lead to positive pK a shifts.…”

“…З метою вивчення природи та кінетики хімічної взаємодії ЛЗ (С = 3,3•10 -5 м) із САЛ (С = 0,33 мг/мл) було проведено мікрокалориметричні дослідження у 0,9%-му розчині натрію хлориду в режимі змішування при 26 °С на мікрокалориметрі LKB-2107 (Швеція). Розрахунки теплового ефекту реакції проводили на 1 л розчину за 10-хвилинний період часу з моменту змішування [24].…”
