RS47

Avis client

Based on 1 Customer Validation

RS47 is a selective RelB inhibitor with a Kd value of 1.1 μM. RS47 also acts as an inhibitor of HCV replication. RS47 can block the non-canonical NF-κB signaling pathway without affecting the canonical pathway. RS47 exerts anti-tumor effects of inhibiting proliferation and promoting apoptosis on colorectal cancer, B-cell lymphoma and other related tumors both in vitro and in vivo by disrupting the binding of RelB to target DNA. RS47 can be used for the research of tumors and infectious diseases.

In Vitro

RS47 (0-10 μM) inhibits HCT116, BJAB and U2932 cells viability with IC₅₀ values of 1.28 , 0.255 and 0.159 μM^[1].
RS47 (0-3 μM; 0-7 days) can inhibit the proliferation, colony formation, and invasion of HCT116 cells^[1].
RS47 (0-2 μM; 72 h) induces apoptosis and cell cycle arrest in HCT116/SW620 colorectal cancer cells^[1].
RS47 (0-2 μM; 72 h) promotes apoptosis in BJAB and U2932 cells^[1].
RS47 (1 μM; 24 h) inhibits the expression of BAFF-inducible target genes (e.g., Pim2) in the non-canonical NF-κB pathway in BJAB cells and primary B cells^[1].
RS47 inhibits HCV replication in Huh5-2 cells (EC₅₀ < 2.2 μM)^[2].

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

Cell Proliferation Assay^[1]

Cell Line:

HCT116, SW620
Concentration:

0.5 μM, 1 μM, 2 μM
Incubation Time:

72 h
Result:

Caused a significant decrease in S phase population and an increase in G0/G1 and G2/M phase populations in a dose-dependent manner.

Apoptosis Analysis^[1]

Cell Line:

BJAB, U2932
Concentration:

0 μM, 0.5 μM, 1 μM, 2 μM
Incubation Time:

72 h
Result:

Significantly promoted apoptosis in a dose-dependent manner.

Real Time qPCR^[1]

Cell Line:

BJAB, primary B cells
Concentration:

1 μM
Incubation Time:

24 h
Result:

Inhibited BAFF-induced Pim2 mRNA expression in BJAB cells and primary B cells.

In Vivo

RS47 (50 mg/kg; i.p.; 21 days) inhibits tumor growth of human B lymphoma PDX xenografts in BALB/c athymic nude mice^[1].
RS47 (50 mg/kg; i.p.; 21 days) significantly inhibits tumor growth and downregulates c-Myc expression in BALB/c nude mice with colorectal cancer xenografts^[1]。

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

Animal Model:

BALB/c athymic nude mice (male, 6-week-old, induced by subcutaneous injection of human B lymphoma tissue from PDX models)^[1]
Dosage:

50 mg/kg
Administration:

i.p.; daily
Result:

Remarkably reduced the tumor volume and weight of B lymphoma PDX xenografts. Immunohistochemical staining showed a decreased percentage of Ki-67-positive proliferating cells, and TUNEL assay revealed an increased number of apoptotic cells in the tumor tissues.
Downregulated the mRNA and protein expression of Bcl-2 and MYC, which are associated with cell survival and proliferation.
Had no/little toxicity to mice.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
