CYP17-IN-1 is an effective oral inhibitor of CYP17 that can inhibit CYP17 in rats and humans with IC50 of 15.8 and 20.1 nM.

Clarithromycin (A-56268) is a Macrolide Antimicrobial. The mechanism of action of clarithromycin is as a Cytochrome P450 3A4 Inhibitor, and Cytochrome P450 3A Inhibitor, and P-Glycoprotein Inhibitor. The chemical classification of clarithromycin is Macrolides.

1. Corydaline (Corydalin), an isoquinoline alkaloid, is one of the major active constituents in a new prokinetic botanical agent. 2. Corydaline promotes gastric emptying and small intestinal transit and facilitates gastric accommodation. 3. Corydaline exhibits the anti-acetylcholinesterase, antiallergic, and antinociceptive activities. 4. Corydaline has potent inhibition of CYP2C19 and CYP2C9.

Fipronil (Fluocyanobenpyrazole) is a broad-use insecticide that belongs to the phenylpyrazole chemical family. Fipronil is a broad-spectrum insecticide that disrupts the insect central nervous system by blocking GABA-gated chloride channels and glutamate-gated chloride (GluCl) channels, resulting in central nervous system toxicity. This causes hyperexcitation of contaminated insects' nerves and muscles. Specificity of fipronil on insects may come from a better efficacy on GABA receptor, but also because GluCl channels do not exist in mammals.

PF-4981517 (CYP3cide) is a efficient, specific and time-dependent inhibitor of cytochrome P4503A4 (CYP3A4). The IC 50 values for CYP3A activity are 0.03 μM,17 μM, and 71 μM for CYP3A4, CYP3A5, and CYP3A7, respectively. PF-4981517 is able to be used to distinguish the contributions of CYP3A4 versus CYP3A5 on drug Metabolism.
