Itraconazole is a potent inhibitor of CYP3A4 which can be used as a triazole antifungal agent [1].
Cytochrome P450 3A4, abbreviated CYP3A4, is an important enzymethat oxidizessmall foreign organic molecules (xenobiotics).
In vitro: Itraconazole was metabolized into hydroxy-itraconazole (OH-ITZ), a known in vivo metabolite of ITZ, and two new metabolites: keto-itraconazole (keto-ITZ) and N-desalkyl-itraconazole (ND-ITZ). Itraconazole was a substrate for CYP3A and to characterize the metabolites generated. Itraconazole exhibited an unbound Km of 3.9 nM for CYP3A. Itraconazole metabolites are as potent as or more potent CYP3A4 inhibitors than ITZ itself [1]. Itraconazole was pharmacologically distinct from other azole antifungal agents. Itraconazole has been shown to inhibit both the hedgehog signaling pathway and angiogenesis [2] Itraconazole was active against 60 clinical isolates of Aspergillus spp. with geometric mean (GM) MICs of 0.25 mg/mL [3]. Itraconazoleshowed an affinity for mammalian cytochrome P-450 enzymes as well as for fungal P-450-dependent enzyme, and thus has the potential for clinically important interactions [4].
In vivo: Oral Administration of itraconazole (200 mg) once daily for 4 days increased the area under the midazolam concentration-time curve from 10 to 15 times (p < 0.001) and mean peak concentrations three to four times (p < 0.001) compared with the placebo phase [5].

Cell lines |
C. glabrata, C. kefyr |
|
Preparation method |
The solubility of this compound in DMSO is > 8.8mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months. |
|
Reacting condition |
0.016 μg/ml |
|
Applications |
Itraconazole showed antifungal activity against 206 isolates of C. glabrata. For 144 isolates, two or more replicate test results were recovered from the database. In five replicate tests with two bioassay strains of C. kefyr (SA and ATCC 46764), the IC50 of itraconazole was 0.016 mg/L. |
| Animal experiment [2]: | |
|
Animal models |
CD1 mice model of disseminated candidiasis |
|
Dosage form |
5 mg/kg, twice daily for 5 days |
|
Application |
Treatment with ITZ led to lower numbers of CFU per gram of kidney. The survival rates for mice inoculated with strain Sr and isolate B were 7 of 10 in mice treated with ITZ. |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
