BJ-2302
BJ-2302 is a Src kinase inhibitor with an IC50 of 3.23 μM, and inhibits cathepsin S (CTSS) activity.BJ-2302 binds to Src, suppresses PI3K/AKT and Ras/Raf/ERK pathways, and reduces CTSS and MMP-9 expression.BJ-2302 inhibits cancer cell invasion, metastasis, proliferation, and tumor growth.BJ-2302 does not induce cytotoxicity in normal breast epithelial cells.BJ-2302 can be used for the research of breast cancer and triple-negative breast cancer.

Biological Activity
BJ-2302 inhibits Src-regulated PI3K/AKT and Ras/Raf/ERK signaling pathways in MDA-MB-231 cells, and suppresses the invasion of MDA-MB-231 cells[1].
BJ-2302 (0.01-10 µM; 18 h) inhibits serum-induced invasion of MDA-MB-231 triple-negative breast cancer (TNBC) cells, with an IC50 of 0.08 µM and an IC90 of 0.71 µM[3].
BJ-2302 (0.01-10 µM) downregulates the mRNA and protein expression of basal CTSS and MMP-9 in MDA-MB-231 triple-negative breast cancer (TNBC) cells in a concentration-dependent manner[3].
BJ-2302 (0.01-1 µM) inhibits the nuclear translocation of NF-κB, and suppresses the phosphorylation of PI3K/Akt as well as the phosphorylation of molecules in the Ras/Raf/ERK pathway in a concentration-dependent manner in vitro in MDA-MB-231 triple-negative breast cancer (TNBC) cells[3].
BJ-2302 (0.01-10 µM; 73 h) inhibits serum-induced proliferation of MDA-MB-231 triple-negative breast cancer (TNBC) cells in a concentration-dependent manner, and achieves complete inhibition of proliferation at a concentration of 1 µM[3].
BJ-2302 (0.01-1 µM; 19-73 h) inhibits 5-hydroxytryptamine (5-HT)-induced proliferation, invasion, CTSS/MMP-9 expression, and Src phosphorylation in MDA-MB-231 triple-negative breast cancer (TNBC) cells in a concentration-dependent manner in vitro[3].

Cell Line:MDA-MB-231 human triple-negative breast cancer (TNBC) cells
-
Concentration:0.01, 0.1, 1 and 10 µM
-
Incubation Time:18 h
-
Result:Inhibited serum-induced MDA-MB-231 cell invasion in a concentration-dependent manner, with an IC50 of 0.08 µM and an IC90 of 0.71 µM.
Demonstrated stronger maximum inhibitory effect than Z-FL-COCHO or batimastat, which had IC90 values greater than 10 µM.
-

Achieved complete suppression of serum-induced cell proliferation at 1 µM.
BJ-2302 (3-30 pmol/CAM; administered at cell seeding; treatment duration of 5 days) exerts concentration-dependent inhibition on tumor growth, angiogenesis and metastasis of triple-negative breast cancer in the chick embryo chorioallantoic membrane (CAM) xenograft model[3].

-
Animal Model:BALB/C nude (7-8 weeks old, female, triple-negative breast cancer subcutaneous model)[3]
-
Dosage:1 mg/kg
-
Administration:i.p.; daily; 25 days
-
Result:Significantly suppressed tumor volume and tumor weight, with greater efficacy than Z-FL-COCHO (HY-15533) (1 mg/kg) or Batimastat (HY-13564) (30 mg/kg).
Reduced in vivo bioluminescent imaging signals from tumors much lower compared to controls and other treatment groups.
Did not cause progressive body weight loss.
-
Animal Model:Fertile chicken embryos (developing, triple-negative breast cancer CAM xenograft model)[3]
-
Dosage:3 pmol/CAM; 30 pmol/CAM
-
Administration:at cell inoculation; maintained for 5 days
-
Result:Suppressed tumor growth and tumor-induced angiogenesis in a concentration-dependent manner, with greater efficacy than Z-FL-COCHO (30 pmol/CAM) or Batimastat (300 pmol/CAM).
Significantly suppressed metastasis of MDA-MB-231-luc2-tdTomato cells to the lungs, liver, and bottom CAM, as evidenced by reduced red-fluorescence-labeled cancer cells and decreased human HPRT mRNA expression in these tissues, with stronger activity than Z-FL-COCHO or batimastat.
