“…According to equations and using K 2 = 2/3, n = 1.36 and Φ = 0.15 for BSA , the following data are obtained: J = 1.74 × 10 ‐16 cm 3 /L/mol, R 0 = 1.28 nm, r = 1.54 nm and E = 25.47% for the DHA–BSA system; and J = 2.62 × 10 ‐16 cm 3 /L/mol, R 0 = 1.37 nm, r = 1.65 nm and E = 25.07% for the ART–BSA system. The observed donor–acceptor distances ( r ) of the two systems are < 8 nm, again indicating that static quenching interactions occurred between BSA and DHA/ART . The average distance of BSA–DHA is smaller than that of BSA–ART, indicating that the interaction between DHA and BSA is stronger than between ART and BSA.…”

The interactions of dihydroartemisinin (DHA) and artemisinin (ART) with bovine serum albumin (BSA) have been investigated using fluorescence, UV/vis absorption and Fourier transform infrared (FTIR) spectra under simulated physiological conditions. The binding characteristics of DHA/ART and BSA were determined by fluorescence emission and resonance light scattering (RLS) spectra. The quenching mechanism between BSA and DHA/ART is static. The binding constants and binding sites of DHA/ART-BSA systems were calculated at different temperatures (293, 298, 304 and 310 K). According to Förster non-radiative energy transfer theory, the binding distance of BSA to DHA/ART was calculated to be 1.54/1.65 nm. The effect of DHA/ART on the secondary structure of BSA was analyzed using UV/vis absorption, FTIR, synchronous fluorescence and 3D fluorescence spectra. In addition, the effects of common ions on the binding constants of BSA-DHA and BSA-ART systems were also discussed.

“…The dilution enthalpy of 4 H 2 O(l) as one of the products in the reaction (1) in the solution C is within the range of experimental error and cannot be detected by the existing isoperibol solution calorimetry. According to the literature [14], the amount of H 2 O(l) was very small in accordance with the stoichiometric number of H 2 O(l) in the reaction, which can be omitted, i.e., D s H m H (5) = 0 kJ mol -1 .…”

A new ternary bismuth complex [Bi(C 7 H 5 O 3 ) 3-C 12 H 8 N 2 ] (C 7 H 6 O 3 , o-hydroxybenzoic acid; C 12 H 8 N 2 , 1,10-phenanthroline monohydrate) and its crystal were prepared and characterized. The results showed that the crystal is triclinic, space group P ī with a = 10.184 (2) ) = 776. The crystal contains a mononuclear molecule. Bi 3? is eight-coordinated by three bidentate chelating carboxylic groups and one o-phenanthroline molecule; C 7 H 6 O 3 coordinated with Bi 3? in the form of carboxylate; the two nitrogen atoms of C 12 H 8 N 2 are bidentate-coordinated with Bi 3? forming a chelate ring. At 298.15 K, the standard molar enthalpy of formation of the title complex was estimated to be D f H m H [Bi(C 7 H 5 O 3 ) 3 C 12 H 8 N 2 (s), 298.15 K] = -(303.99 ± 4.95) kJ mol -1 .
