Molarity Calculator

Serpin B9-IN-1 (BTCA) is an inhibitor that specifically targets Serpin B9 (SB9); SB9 is a natural inhibitor of granzyme B (GrB) , but may promote the metastasis of lung cancer cells into the bone marrow. SB9-overexpressing cancer cells promote proliferation and metastasis in an immune cell-dependent manner by binding to GrB. Inhibition of SB9 by Serpin B9-IN-1 significantly inhibits immunotherapy of lung cancer bone metastases in the caudal artery (CA) mouse model (LCBM).

Description

Serpin B9-IN-1 (BTCA) is an inhibitor that specifically targets Serpin B9 (SB9); SB9 is a natural inhibitor of granzyme B (GrB) , but may promote the metastasis of lung cancer cells into the bone marrow. SB9-overexpressing cancer cells promote proliferation and metastasis in an immune cell-dependent manner by binding to GrB. Inhibition of SB9 by Serpin B9-IN-1 significantly inhibits immunotherapy of lung cancer bone metastases in the caudal artery (CA) mouse model (LCBM)[1].

IC50 & Target

IC50: Serpin B9
In Vivo

Serpin B9-IN-1 (BTCA) inhibits bone metastasis (BM) in multiple tumor metastasis models. Serpin B9-IN-1 (50 mg/kg/d; ip; 14 d) effectively reduced the survival rate and metastasis proportion of metastatic cancer cells in the mouse bone metastasis model with LLC1-BM3 injected into the tail artery (CA)[1].
Serpin B9-IN-1 (300 μg/d; ip; 14 d) effectively delayed the average time to bone metastasis (BM) in the LLC1-BM3 cell group[1].

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

Animal Model: LLC1-BM3 Bone Metastatic Mouse Model by CA injections[1]
Dosage: 50 mg/kg
Administration: ip; followed after cancer cell injection, injection daily for 14 days
Result: Reduced the survival rate and metastasis proportion of metastatic cancer cells
Animal Model: LLC1-BM3-sr-ctrl Model in Mouse[1]
Dosage: 300 μg
Administration: ip; once daily for 14 days
Result: Delayed the mean time to occurrence of bone metastasis (BM), and lowered the burden of BM in LLC1-BM3-shSB9 cells group.

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.
