Description

Acoziborole (SCYX-7158) is an effective, safe and orally active antiprotozoal agent for the research of human african trypanosomiasis (HAT). In the T. b. brucei S427 strain, the MIC value for SCYX-7158 is 0.6 µg/mL[1].

In Vitro

Acoziborole is active in vitro against relevant strains of Trypanosoma brucei, including T. b. rhodesiense and T. b. gambiense.In whole cell assays, Acoziborole exhibits potent activity against representative T. b. brucei, T. b. rhodesiense and T. b. gambiense strains. IC50 values for Acoziborole are approximately 0.07 µg/mL to 0.37 µg/mL following incubation of the parasite strains with Acoziborole for 72 h. In the T. b. brucei S427 strain, the MIC value for Acoziborole is 0.6 µg/mL, approximately two times the IC50 measured for this strain. In contrast to the potent activity of Acoziborole against trypanosomes, no significant inhibition of cell proliferation is observed in an in vitro mammalian cell (L929 mouse cell line) assay at drug concentrations up to 50 µg/mL. The potential for Acoziborole to inhibit cytochrome P450 (CYP) enzymes is evaluated using P450-Glo assays for the human isoforms CYP3A4, CYP1A2, CYP2C19, CYP2C9 and CYP2D6. The IC50 values for Acoziborole in these assays are all above 10 µM[1].

In Vivo

In uninfected mice, 4.3 mg/kg intravenous dose of Acoziborole show an apparent elimination half-life (t1/2) of 26.6 h; systemic clearance (CL) of 0.089 L/h/kg; a volume of distribution (Vdss) of 1.69 L/kg and area under the concentration-time curve (AUC0-24 h) of 48 h•μg/mL. Following an oral dose of 13.4 mg/kg, which corresponds to the lowest efficacious dose in the murine stage 2 HAT model, Acoziborole is rapidly absorbed, as a Cmax of 6.96 µg/mL is achieved in plasma at 6 h after dose, with an oral clearance (Cl/F) value of 0.163 L/h/kg, an AUC0-24 h of 82 h•μg/mL and absolute oral bioavailability of 55%. After a 26 mg/kg oral dose, which corresponds to the dose giving a 100% cure rate in the murine stage 2 HAT model, Cmax increases to 9.8 µg/mL and the AUC0-24 h is 113 h•μg/mL. In uninfected rats, following oral administration of Acoziborole at a nominal dose of 25 mg/kg (dose affording a 100% cure rate in mice), Cmax increases approximately 2 fold more than that in mice (Cmax=18.2 µg/mL) and AUC0-24 h, and hence oral clearance, improves approximately 4 fold (AUC0-24 h 291 h•μg/mL and CL/F=0.092 L/kg/h). The time to maximum concentration is similar to that in mice (tmax=8 h). Uninfected male and female cynomolgus monkeys are treated with Acoziborole at 2 mg/kg (IV) on study day 1 and 10 mg/kg (NG) on study day 8. Acoziborole exhibits excellent plasma pharmacokinetics, with CL of 0.022 L/h/kg; Vdss of 0.656 L/kg and area under the concentration-time curve 78.8 h•μg/mL, and 94.4 for AUC0-24 h and AUC0-inf, respectively, following intravenous administration[1].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Cell Assay
[1]

Compounds (e.g., Acoziborole) to be tested are serially diluted in DMSO and added to 96-well plates to give final concentrations ranging from 5 to 0.01 µg/mL. T. b. brucei parasites in the log phase of growth are diluted in HMI-9 media and added to each well for a final concentration of 1×104 parasites per well. For the sensitivity assays using T. b. rhodesiense and T. b. gambiense, pararasites are cultured in MEM supplemented with Baltz components, diluted in the aforementioned culture media, and added to each well at a density of 1×103 cells/well. The final concentration of DMSO is 0.5% and the total volume is 100 µL/well. After 72 h incubation, Resazurin is added to each well (20 µL of 25 mg/100 mL stock in PBS) and incubated for an additional 4-6 h. To assess cell viability, fluorescence is quantified using an EnVision Multilabel Plate Reader at an excitation wavelength of 530 nm and emission of 590 nm. Triplicate data points are averaged to generate sigmoidal dose-response curves and determine IC50 values using XLfit curve fitting software. The IC50 is defined as the amount of compound required to decrease parasite or cell viability by 50% compared to those grown in the absence of the test compound. The MIC, defined as the lowest concentration of compound that completely inhibits visible parasite growth, is determined by visual inspection of 96-well plates after 48-72 h of incubation with the test compounds. To evaluate the effects of serum on trypanocidal activity, assays are performed in the presence of increasing concentration (2.5% to 50%) of fetal calf serum. The results are expressed as a fold-change in IC50 values relative to standard conditions (10% FCS) [1].

Animal Administration
[1]

Mice, Rats and Monkeys[1]
Male CD-1 mice (~25 g), male Sprague-Dawley rats (~225 g), or male cynomolgus monkeys (~3-5 kg) are administered test article by either bolus intravenous injection (IV) or oral gavage. Male CD-1 mice, Sprague-Dawley rats, cynomolgus monkeys or male beagle dogs are administered a single oral dose of Acoziborole at a dose of 25 mg/kg (mouse, rat) or 10 mg/kg (monkey, dog). Blood samples are collected and analyzed.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
