Reporter substrate was nitrocefin (200 M, K m 200 µM). For a variety of reasons, pharmacologists often construct ‘inhibition curves’ to evaluate antagonists rather than employing the more comprehensive ‘Schild analysis’. There is a widespread perception that it is only possible to derive antagonist Kb, values from such experiments via application of the Cheng-Prusoff equation, requiring knowledge of the agonist affinity at the receptor.

IC 50 is not a direct indicator of affinity, although the two can be related at least for competitive agonists and antagonists by the Cheng-Prusoff equation. For enzymatic reactions, this equation is: = + [] where K i is the binding affinity of the inhibitor, IC 50 is the functional In the 1970s, Prusoff coformulated the Cheng-Prusoff equation to calculate the absolute inhibition constant K i. In the 1980s, while the AIDS epidemic was spreading and found to be caused by HIV, William Prusoff and the late dr. Tai-Shun Lin discovered that a compound synthesized by dr. Jerome Horwitz had potent anti-HIV properties. 1993-08-01 Cheng-Prusoff Equation Used to determine the Ki value from an IC50 value measured in a competition radioligand binding assay: Where [L] is the concentration of free radioligand, and Kd is the dissociation constant of the radioligand for the receptor. the Cheng–Prusoff transformation (K i = IC 50/(1 + [L]/K dL).

Using a radioligand with a lower Kd (higher affinity) will increase the IC50. Calculate the Ki from the IC50, using the equation of Cheng and Prusoff (Cheng Y., Ki was calculated using the Cheng-Prusoff equation [30].

1993-08-01 Cheng-Prusoff Equation Used to determine the Ki value from an IC50 value measured in a competition radioligand binding assay: Where [L] is the concentration of free radioligand, and Kd is the dissociation constant of the radioligand for the receptor. the Cheng–Prusoff transformation (K i = IC 50/(1 + [L]/K dL). In this paper, we usually use the designation A for an unla-belled ligand; in this case, it is the dissociation constant for A, K dA that corresponds to K i.

For enzymatic reactions, this equation is: = + [] Introduction: The Cheng-Prusoff equation (1973) is often applied to the determination of equilibrium dissociation constant (KB) of a competitive antagonist when the IC50 value is available. The purpose of this study is to illustrate that the slope function (K) of an agonist concentration-response curve is critical to the determination of KB values. The Cheng-Prusoff equation defines the theoretical relation-ship between the measured IC 50 for a competitive inhibitor of given K i, the concentration of labeled ligand, and the K D of the ligand-receptor interaction. K i = IC 50 /(1 + ([L]/K D)), where [L] = the concentration of labeled ligand, K i = the inhibition constant, defined as the equilibrium concen- As a demonstration of the amazing effect of this substitution let's use it to rewrite famous Cheng-Prusoff equations: I 50 =K d (1+ T 0 /K d * ) [1] where I 50 is the concn. of inhibitor giving 50% inhibition; K d - dissociation constant of inhibitor-binder reaction; K d * - dissociation const.
