Biological Activity

Description Posaconazole (SCH56592) is an inhibitor primarily of CYP3A4, but it does not inhibit the activity of other CYP enzymes; Also an inhibitor of sterol C14ɑ demethylase inhibitor with IC50 of 0.25 μM. Posaconazole has a median terminal elimination half-life of 15-35 hours.
Features Currently the most advanced candidate for the treatment of Chagas disease.
lanosterol 14α-demethylase [1]
CYP3A4 [6]
In vitro

Posaconazole has potent trypanocidal activity. Amiodarone acts synergistically with Posaconazole. Posaconazole also affects and disrupts Ca2+ homeostasis in T. cruzi. Posaconazole blocks the biosynthesis of ergosterol, which is essential for parasite survival. Posaconazole has a clear, dose-dependent effect on proliferation of the epimastigote (extracellular) stages, with a minimal inhibitory concentration of 20 nM and an IC50 of 14 nM. Against the clinically relevant intracellular amastigote form of the parasite, Posaconazole is even more potent. Posaconazole has the minimal inhibitory concentration and IC50 values of 3 nM and 0.25 nM. [1] Posaconazole is active against isolates of Candida and Aspergillus spp. that exhibit resistance to Fluconazole, Voriconazole, and Amphotericin B and is much more active than the other triazoles against zygomycetes.

PubMed: 28383032     

Protein lysates from tivozanib-treated cells were subjected to Western blotting and probed with the indicated antibodies. β-actin was used as the loading control. The concentrations of tivozanib were 5, 10 and 20 μM. The blots are representative of three independent experiments with similar outcomes. 

In vivo Treatment of infected animals with amiodarone alone reduces parasitemia, increases survival 60 days pi (0% for untreated controls vs 40% for amiodarone-treated animals) and, when given in combination with Posaconazole, delays the development of parasitemia. [1] Coadministration of Posaconazole and Boost Plus increases drug exposure compared to the administration of Posaconazole alone in the fasted state. Food, particularly meals high in fat content, significantly increases Posaconazole bioavailability. Systemic exposure to Posaconazole increases 4- and 2.6-fold when it is consumed with a high-fat and nonfat meal, respectively. [3] Posaconazole and Amiodarone may constitute an effective anti-T. cruzi therapy with low side effect. [4] At twice-daily doses of ≥15 mg/kg of body weight, Posaconazole prolongs the survival of the mice and reduces tissue burden. [5]


Cell Research:


- Collapse
  • Cell lines: Epimastigote form of T. cruzi amastigotes
  • Concentrations: 0 nM -4 nM
  • Incubation Time: 96 hours
  • Method:

    The epimastigote form of the parasite is cultivated in liver infusion tryptose medium, supplemented with 10% new born calf serum at 28 °C with strong (120 rpm) agitation. Cultures are initiated at a cell density of 2 × 106 epimastigotes/mL, and Posaconazole is added at a cell density of 0.5−1.0 × 107 epimastigotes/mL. Cell densities are measured by using an electronic particle counter as well as by direct counting with a hemocytometer. Cell viability is followed by Trypan blue exclusion, using light microscopy. Amastigotes are cultured in Vero cells maintained in minimal essential medium supplemented with 1% fetal calf serum in a humidified atmosphere (95% air−5% CO2) at 37 °C. Cells are infected with 10 tissue culture-derived trypomastigotes per cell for 2 hours and then washed three times with phosphate-buffered saline (PBS) to remove nonadherent parasites. Fresh medium with and without Posaconazole is added, and the cells are incubated for 96 hours with a medium change at 48 hours. The percent of infected cells and the numbers of parasites per cell are determined directly using light microscopy, and a statistical analysis of the results is carried out. IC50 values are calculated by nonlinear regression, using the program GraFit. Fractional inhibitory concentrations (FIC) are calculated. Cytoplasmic free Ca2+ concentrations in control and drug-treated extracellular epimastigotes are determined by fluorimetric methods using Fura-2. Subcellular Ca2+ levels and mitochondrial membrane potentials are monitored on individual Vero cells infected with T. cruzi amastigotes by using time-scan confocal microscopy. Briefly, Vero cells heavily infected (72 hours) with T. cruzi amastigotes are plated onto 22 × 40 mm glass coverslips (0.15 mm thickness) and incubated simultaneously with 10 μM cell-permeant Rhod-2 and 10 μg/mL Rhodamine-123 for 50 minutes at 37 °C in culture medium and then washed and incubated with Ringer's solution, with or without amiodarone. Under the conditions used fluorescence of Rhod-2 comes mainly from intracellular Ca2+-rich compartments, like mitochondria, since its low affinity for Ca2+ limits its fluorescence in the Ca2+-poor cytoplasm of the Vero cells or amastigotes. Rhodamine-123 is a mitochondrion-specific cationic dye, which distributes across the inner mitochondrial membranes strictly according to their membrane potential.
