Rational use of plasma protein and tissue binding data in drug design.
Journal of Medicinal Chemistry, 2014It is a commonly accepted assumption that only unbound drug molecules are available to interact with their targets. Therefore, one of the objectives in drug design is to optimize the compound structure to increase in vivo unbound drug concentration.

Plasma protein binding: from discovery to development.
Journal of Pharmacy and Science, 2013The importance of plasma protein binding (PPB) in modulating the effective drug concentration at pharmacological target sites has been the topic of significant discussion and debate amongst drug development groups over the past few decades.

Species differences in drug plasma protein binding
, 2014Comparison of the human plasma protein binding data for a variety of drug discovery compounds indicates that compounds tend to be slightly more bound to human plasma proteins, than compared to plasma proteins from rats, dogs or mice.

The plasma protein binding of HIDA
European Journal of Nuclear Medicine, 1980By using Sephadex gel column chromatography to separate substances into their various components according to molecular weight, we have investigated the effect of incubating several "brands" of HIDA in plasma, in vitro. The results show that such incubation has no effect on either dimethyl HIDA, or diethyl HIDA, but that in the case of para-butyl HIDA,

Oestriol binding to plasma proteins
Journal of Steroid Biochemistry, 1988Simple diffusion experiments indicated that oestriol was retained by human pregnancy plasma more effectively than by albumin solutions of a corresponding concentration. Oestriol bound (Ka = 6 X 10(6) l/mol at 4 degrees C) to a glycoprotein which had been isolated from plasma by adsorption to Concanavalin A.

The binding of cortisol by plasma protein
Archives of Biochemistry and Biophysics, 1958Abstract When plasma cortisol concentrations are less than 30 μg./100 ml., the steroid is tightly bound by protein and cannot be ultrafiltered. When the concentration is raised higher than 40 μg./100 ml., either by addition of exogenous cortisol in vitro or as a result of the effects of adrenocorticotropic hormone (ACTH) or of sickness on the ...

Quantitative structure--plasma protein binding relationships of acidic drugs.
Journal of Pharmacy and Science, 2012One of the most important factors, affecting significantly the overall pharmacokinetic and pharmacodynamic profile of a drug, is its binding to plasma protein (PPB).

Binding Affinities of Thyroxine-Binding Proteins in Turtle Plasma
General and Comparative Endocrinology, 1993Binding affinities (Ka) for thyroxine (T4) by blood plasma and purified plasma proteins from two turtles, the slider (Trachemys scripta) and snapper (Chelydra serpentina), were compared with those of a human using equilibrium dialysis. The purified T4 binding protein (TBP) from T.

Mn++ BINDING BY PLASMA PROTEINS
International Journal of Peptide and Protein Research, 197354Mn2+ added to human or rabbit plasma in vitro combines selectively with the albumin fraction. At pH 7.0, the Scatchard plot yields a curve that may be resolved for two classes of sites: one, where n1 = 1 and K1 = 2.4 × 104, the other where n2 = 0.5 and K2 = 0.5 × 103.Zn2+, Ni2+ and Co2+ can compete effectively for these sites.

Renin binding proteins in plasma
Biochimica et Biophysica Acta (BBA) - Protein Structure, 1979Renin is found in mouse plasma as high molecular weight forms, in addition to the fully active 40 000 dalton form. By using freshly 125 I-labelled 40 000 dalton pure submaxillary mouse renin, no binding to plasma proteins was demonstrable. However, unfolding and refolding of the labelled renin by guanidine facilitated binding to specific mouse and ...
