ITC does not require any labeling or modification of the interacting partners analyzed and can be performed in solution with small amounts of reagents.

Isothermal titration calorimetry (ITC) is the only technique that allows quantitative determination of all thermodynamic parameters, including the equilibrium binding constant (K B), the standard Gibbs free energy change (ΔG), the enthalpy change (ΔH), the entropy change (ΔS), heat capacity change (ΔC p), and stoichiometry (n) of the reaction. Characterization of the nature of anesthetic-protein interactions therefore is important and requires the complete analysis of the binding energetics.

This work suggests that kinetic-based structure-activity of opioids in drug design and incorporation into the pharmacokinetics-pharmacodynamics predictions may have more value than thermodynamic equilibrium constants alone.Īctivation G-protein coupled receptor Kinetic selectivity Opioid Surface plasmon resonance Thermodynamics Transition state analysis.Ĭopyright © 2019 Elsevier B.V. 2 Department of Drug Delivery Research, Graduate School. Temperature-dependent SPR assays provided access to rate and equilibrium thermodynamic data, which demonstrated binding of morphine and naloxone to μOR was exothermic and essentially enthalpy driven.

Contrary, on and off rates exhibited much larger dispersion and well correlated with EC 50 values, indicating that opioids might exhibit kinetic-selectivity towards their target. However, they did not correlate with their in vitro EC 50 values, indicating that they might not have thermodynamic selectivity. Khazar Babazada (FM) Born: 2005: Results: Win: 53.6 (339) Loss: 23.7 (150) Draw: 22.7 (144) Total:633: White Results: Win: 54.6 (173) Loss: 24.9 (79) Draw: 20.5 (65) Total:317: Black Results: Win: 52.5 (166) Loss: 22. Thermodynamic equilibrium affinities of opioids were in narrow nanomolar range and in near quantitative agreement with their K i values.

The uniform immobilization of h-μOR on Ni-NTA chips was achieved using hybrid capture-coupling approach followed by reconstitution in lipid bilayer. corrplot (df) returns a color-encoded heatmap, ideal for correlations-klib.

Receptor was purified, detergent-solubilized and characterized by circular dichroism. DataFrame (data) scribe - functions for visualizing datasets-klib. The N-terminal end truncated and C-terminal 6His-tagged h-μOR was constructed and expressed in E. Here, combined kinetics and thermodynamics of opioid agonist binding to human μ-opioid receptor (h-μOR) was investigated using real-time label-free surface plasmon resonance (SPR)-based method. Development of opioid analgesics with minimal side effects requires substantial knowledge on structure-kinetic and -thermodynamic relationship of opioid-receptor interactions.
