Index inducer or just inducer predictably induce metabolism via a given pathway and are commonly used in prospective clinical drug-drug interaction studies. [2]Strong, moderate, and weak inducers are drugs that decreases the AUC of sensitive index substrates of a given metabolic pathway by ≥80%, ≥50% to <80%, and ≥20% to <50%, respectively.
Following is a table of selected substrates, inducers and inhibitors of CYP1A2. Inhibitors of CYP1A2 can be classified by their potency, such as: Strong inhibitor being one that causes at least a 5-fold increase in the plasma AUC values of sensitive substrates metabolized through CYP1A2, or more than 80% decrease in clearance thereof.

Index inducer or just inducer predictably induce metabolism via a given pathway and are commonly used in prospective clinical drug-drug interaction studies. [ 4 ] Strong, moderate, and weak inducers are drugs that decreases the AUC of sensitive index substrates of a given metabolic pathway by ≥80%, ≥50% to <80%, and ≥20% to <50% ...
An enzyme inducer is a type of drug that increases the metabolic activity of an enzyme either by binding to the enzyme and activating it, or by increasing the expression of the gene coding for the enzyme. [1] [page needed] It is the opposite of an enzyme repressor.
Two such inhibitors, indazole and 4-methylpyrazole, coordinate with the active site's iron atom and were crystallized with recombinant human CYP2E1 in 2008 to give the first true crystal structures of the enzyme. [14] Other inhibitors include diethyldithiocarbamate [21] (in cancer), and disulfiram [22] (in alcoholism).
Substrate analogs can act as competitive inhibitors of an enzymatic reaction. An example is phosphoramidate to the Tetrahymena group I ribozyme. [ 1 ] Other examples of substrate analogs include 5’-adenylyl-imidodiphosphate, a substrate analog of ATP , and 3-acetylpyridine adenine dinucleotide, a substrate analog of NADH .
CYP17A1 inhibitors may inhibit one or both of the enzyme’s functions: 17α-hydroxylase and 17,20-lyase. Some inhibitors are selective and target only the 17,20-lyase function, while others inhibit both functions. [2] By inhibiting these enzymatic functions, CYP17A1 inhibitors prevent the conversion of pregnane steroids into androgens like ...
