In Vitro

Carfilzomib displays preferential in vitro inhibitory potency against the ChT-L activity in the β5 subunit, with over 80% inhibition at doses of 10 nM and above and little or no effect on the PGPH and T-L activities at doses up to 100 nM. Carfilzomib decreases the viability of ANBL-6, RPMI 8226 cells, U266 and KAS-6/1 cells with an IC50 less than 5 nM. Carfilzomib overcome Dex resistance, in that MM1.R cells reveals an IC50 of 15.2 nM, less than the value of 29.3 nM for parental MM1.S cells[1]. Co-treatment with carfilzomib and HDACIs leads to synergistic induction of cell death in various mantle cell lymphoma lines and primary mantle cell lymphoma cells. Combined treatment with carfilzomib or ONX0912 with vorinostat in HF-4B and Granta cells sharply increases caspase activation, PARP cleavage, JNK activation, MnSOD2 induction, and DNA damage[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Carfilzomib (2.0 mg/kg, i.v.) in conbination with 70 mg/kg vorinostat virtually abrogates tumor growth in Granta-luciferace cell xenograft flank model. Combined treatment results in a pronounced reduction in bioluminescence compared to animals treated with single agents or controls with minimal toxicity[2].

Carfilzomib exhibits high plasma clearance (195-319 mL/min•kg), short terminal half-life (5-20 min), and rapid and extensive tissue distribution in rats. Carfilzomib exposure (Cmax and area under the curve) increases with dose. The high clearance is primarily mediated by extrahepatic metabolism via peptidase cleavage and epoxide hydrolysis, with approximately 26% and 31% of the total dose in urine and bile, respectively. Despite the high systemic clearance, strong proteasome inhibition was observed in blood and multiple tissues[2].
Carfilzomib can be used in animal models to construct models of cardiotoxicity and hypertension.
1. Cardiotoxicity Model[3]
Pathogenic mechanism
Carfilzomib inhibits AMPKα-mediated autophagy and the PI3K/Akt/eNOS axis, subsequently leading to cardiomyocyte damage and apoptosis, resulting in cardiotoxicity.
Specific modeling method
Mice: C57BL/6 • male • 12-week-old
Administration: 8 mg/kg • i.p. • once every two days for 6 days
Modeling success index
Molecular changes: Reduced phosphorylation of AMPKα, Raptor, LC3-II, PI3K, Akt, and eNOS.
Hemodynamics: Left ventricular FS% decreased, which means the contractile function weakened.
Antagonist products Metformin (HY-B0627)
2. Hypertension Model[4]
Pathogenic mechanism
Carfilzomib induces AMPKα dephosphorylation, leading to dysregulation of renal collecting duct ion channel homeostasis, thereby dysregulating water ion reabsorption and increasing cardiac preload to induce hypertension.
Specific modeling method
Mice: C57BL/6 • male • 12-14 weeks old
Administration: 8 mg/kg • i.p. • once every 2 days for 7 days
Modeling success index
Molecular changes: Inducible nitric oxide synthase (iNOS) and microtubule-associated protein 1A/1B light chain 3B (LC3-B) expression increased, and AMPKα phosphorylation decreased. Collecting duct ion channel epithelial Na+ channel (ENaC), Na+/K+/ATPase, and urea transporter 1 (UTA-1) mRNA levels increased.
Behavioral observations: Inflammation occurred in the perirenal adipose tissue of mice.

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.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: 2.5 mg/mL (3.47 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.5 mg/mL (3.47 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Cell Assay
[1]

WST-1 is used to determine the effects of proteasome inhibitors on cell proliferation according to the manufacturer's protocol. The inhibition of proliferation is calculated in relation to parallel control cells that receive vehicle alone and tabulated in KaleidaGraph 3.0.1 or Excel 2000. A linear spline function is used to interpolate the median inhibitory concentration (IC50) using XLfit 4 software. The degree of resistance (DOR) is calculated using the formula: DOR=IC50(resistant cells)/IC50(sensitive cells).

Animal Administration
[2]

Animal studies are performed utilizing Beige-nude-XID mice. 10×106 Granta514 cells are pelleted, washed twice with 1X PBS, injected subcutaneously into the right flank. Once the tumors are visible, 5 to 6 mice are treated with carfilzomib±vorinostat and progress of tumor growth or regression is monitored. Stock vorinostat and carfilzomib is dissolved in DMSO and 10% sulfobutylether betacyclodextrin in 10 mM citrate buffer pH respectively. They are stored in −80°C in small aliquots and diluted before injection.

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.
