Mechanism of Action

Targets/IC₅₀/Ki	CYP3A4 (human liver microsomes) 6.1 nM
In vitro	Itraconazole is 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). This compound is a substrate for CYP3A in vitro and to characterize the metabolites generated. It exhibits an unbound Km of 3.9 nM for CYP3A. Its metabolites are as potent as or more potent CYP3A4 inhibitors than ITZ itself. This compound appears to act on the essential Hh pathway component Smoothened (SMO) by a mechanism distinct from that of cyclopamine and other known SMO antagonists, and prevents the ciliary accumulation of SMO normally caused by Hh stimulation. It is active against 60 clinical isolates of Aspergillus spp. with geometric mean (GM) MICs of 0.25 mg/mL. It acts primarily by impairing the synthesis of ergosterol, resulting in a defective fungal cell membrane with altered permeability and function. This chemical is effective for a wide variety of mycotic infections and some fungal meningeal infections. It has 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 (e.g., astemizole, terfenadine, rifampin, oral contraceptives, H2 receptor antagonists, warfarin, cyclosporine).
In vivo	Itraconazole, like other Hh pathway antagonists, can suppress Hh pathway activity and the growth of medulloblastoma in a mouse allograft model.

Frequently Asked Questions

Question 1:
We are finding the best vehicle to administer it to mice. We want a mild vehicle (unlike DMSO) which resembles water, PBS, saline (for i.p/ injection) or methyl cellulose (for oral).

Answer:
We are not able to dissolve S2476 clearly without DMSO. For oral gavage, this compound can be dissolved in 1% CMC Na at 20mg/ml as a homogeneous suspension.
