生物活性

Bortezomib (PS-341) is a reversible and selective proteasome inhibitor, and potently inhibits 20S proteasome (Ki=0.6 nM) by targeting a threonine residue. Bortezomib disrupts the cell cycle, induces apoptosis, and inhibits NF-κB. Bortezomib is the first proteasome inhibitor anticancer agent. Anti-cancer activity[1][2].

IC50 & Target

Ki: 0.6 nM (20S proteasome)[1]

体外研究
(In Vitro)

Bortezomib (PS-341) (100 nM; 8 hours) results in the accumulation of cells in G2-M, with a corresponding decrease in the number of cells in G1[1].
Bortezomib (PS-341) (5-100 nM; 20 hours) induces apoptosis in mantle-cell lymphoma (MCL) cell lines[3].
Bortezomib (PS-341) (20 nM; 1-14 hours) induces Noxa up-regulation in both MCL cell lines[3].
The IC50 of Bortezomib (PS-341) is found to be 2.46 nM for 26S proteasome in the B16F10 cells[4].
Bortezomib (PS-341) suppresses several anti-apoptotic proteins (e.g., Bcl-XL, Bcl-2, and STAT-3)[5].

Cell Cycle Analysis[1]

Cell Line: PC-3 cells
Concentration: 100 nM
Incubation Time: 8 hours

Apoptosis Analysis[3]

Cell Line: JVM-2, Granta-519, Jeko, REC-1 cells (MCL cell lines)
Concentration: 5-100 nM
Incubation Time: 20 hours
Result: The median LD50 for these MCL cell lines was 31 nM (range, 18.2-60.1 nM).

Western Blot Analysis[3]

Cell Line: wtp53 (Granta-519), mutp53 (Jeko) cells
Concentration: 20 nM
Incubation Time: 1, 2, 4, 6, 14 hours

体内研究
(In Vivo)

Bortezomib (PS-341) (0.3-1 mg/kg; i.v.; once weekly for 4 weeks) inhibits PC-3 Tumor Growth in Nude Mice[1].

上海金畔生物科技有限公司 has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male nude mice (xenograft tumor model bearing PC-3 cells)[1]
Dosage: 0.3, 1 mg/kg
