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].

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

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.
