Cell lines |
HT-29 colorectal adenocarcinoma cells |
|
Preparation method |
The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20°C for several months. |
|
Reaction Conditions |
1 h; IC50=9 nM |
|
Applications |
Incubation of HT-29 colorectal adenocarcinoma cells with PR-171 for 1 h resulted in a dose-dependent inhibition of all three proteasome catalytic activities with the chymotrypsin-like activity exhibiting the greatest sensitivity (IC50=9 nM). The caspase-like and trypsin-like activities were inhibited to a greater extent in the cellular assay (IC50=150–200 nM) than in the isolated enzyme assay (IC50>1 μM). |
| Animal experiment [1]: | |
|
Animal models |
BNX mice |
|
Dosage form |
5 mg/kg delivered weekly; QDx2; intravenous injection |
|
Applications |
The antitumor activity of PR-171 was evaluated in BNX mice bearing established human tumor xenografts derived from three tumor cell lines: HT-29 (colorectal adenocarcinoma), RL (B cell lymphoma ), and HS-Sultan (Burkitt’s lymphoma). All PR-171 dosing schedules (up to 5 mg/kg delivered weekly QDx2) were tolerated in the tumor-bearing animals, resulting in weight loss of |

Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |

Carfilzomib is an irreversible proteasome inhibitor with an IC50 of 5 nM in ANBL-6 and RPMI 8226 cells.
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].
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].

Abstract
Carfilzomib has been review as a new agent to treat relapsed and refractory MM.
Abstract
Instead of inhibiting the formation of OC sealing zone alone, the combination of cartfilzomib and CC-292 exhibited synergistic anti-MM activities, including inhibition of both sealing zone formation and differentiation of OC, suppression of tumor burden in a mouse model and increasing bone volume.
Abstract
Carfilzomib, a proteasome inhibitor, is an anti-MCL agent that concentration-dependently inhibited cell growth, induced apoptosis and suppressed survival signaling pathways NF-KB and STAT3 without causing toxicity to normal peripheral blood mononuclear cells. Immunoproteasome, particularly LMP2, plays an indispensible role in anti-MCL activity of carfilzomib.
Abstract
Even though it is an FDA-approved anti-MM drug with less than 1% TLS frequency, carfilzomib has been associated with TLS development in a 55-year-old male patient with relapsed MM.
Abstract
Carfilzomib, an FDA-approved anti-MM drug, has been evaluated in the treatment of patients who have relapsed and refractory MM and received prior bortezomib and thalidomide or lenalidomide.
