Affinity

Efficacy
Potency
The terms explained here are in the field of pharmacology
Affinity of a drug refers to how much attraction it faces to the receptor sites in the body. (Drugs function by getting attached to specific receptor sites in the body, thereby activating them)
The term solubility refers to the maximum amount of a substance which can dissolve in given amount of solvent at a given temperature.
The term potency refers to the amount of a drug which can produce half of its maximum effect.
The term efficacy refers to the maximum effect which can be attained with the drug and once this effect is attained with a given amount of drug, any more amount of drug administered doesn't produce any further effect. So the maximum effect a drug can attain is its efficacy.

Drug potency and efficacy is compared with the use of a dose-response curve. Draw a dose response curve. Label and define the parameter that is used to assess potency and efficacy. Make sure to label both the y and the x-axis.
1. (Efficacy/potency) refers to the degree to which a drug is able to produce maximal effects. Which is correct?
Often, the effect of a drug gradually diminishes when it is given continuously or repeatedly. Desensitization and tachyphylaxis are synonymous terms used to describe this phenomenon. Desensitization is a general issue with extended treatment with GPCR agonists as phosphorylation of the receptor interferes with its ability to activate second messenger cascades, although it can still bind the agonist molecule. Which of the following would likely be true for an agonist drug binding to a receptor that has become desensitized over...
Two drugs (Drug A and Drug B) are being investigated for their effectiveness as anticonvulsants in the management of complex partial seizures and simple or complex absence seizures. In early preclinical development, they need to determine the affinity, efficacy, and potency for each drug. The results from the drug-receptor binding curves and the dose-response curves show that: 1) for Drug A it has a low Kd value, a high Emax, and a high EC50, and in comparison 2) Drug B...
The (magnitude/specificity) of a drug effect is related to the effective concentration of the drug present at the receptor. which is correct?
Assignment 2 ü You are encouraged to work in groups (maximum 3) on homework. ü For each part below, please provide the MATLAB code you implemented. ü Do not submit the homework solutions from previous years (The data are different). Dose-Response Modeling (100 points)Suppose that you work for a pharmaceutical company and you are supposed to assess the efficacy and potency of two drugs (Agent A and Agent B) before allowing the agents to proceed to clinical trials. You performed a...
find the maximum speed the stone can attain without breaking the
string
A stone with a mass of 0.700 kg is attached to one end of a string 0.700 m long. The string will break if its tension exceeds 55.0 N. The stone is whirled in a horizontal circle on a frictionless tabletop; the other end of the string remains fixed. A Review A stone with a mass of 0.700 kg is attached to one end of a string 0.700...
