SB-590885
Based on 9 publication(s) in Google Scholar
SB-590885 is a BRAF/c-Raf kinase inhibitor that selectively targets B-Raf, and it amplifies the ERK/MAPK signaling pathway in RAS-activated cells. SB-590885 effectively inhibits the malignant proliferation, transformation and tumorigenicity of oncogenic B-Raf cells; it also induces the proliferation of erythroid progenitor cells, delays their differentiation and promotes hemoglobin synthesis, thereby improving ineffective erythropoiesis and reducing apoptosis. SB-590885 exerts a synergistic effect with TGF-β inhibitors and glucocorticoids, significantly promoting the formation of erythroid colonies in cells from patients with Diamond-Blackfan anemia (DBA). SB-590885 is mainly used in relevant studies on DBA, cisplatin-induced myelosuppression-related anemia, and pan-cancers such as melanoma and colorectal cancer.

SB-590885(1 μM; 12 d) increases the cell number by more than 10-fold compared with the control group in erythroid differentiation culture of UCB-CD34+ hematopoietic stem/progenitor cells, while transiently delaying the erythroid differentiation process[1].
SB-590885(1 μM; 14 d) significantly increases the area of BFU-E erythroid colonies and the total number of erythroid cells, without affecting the proportion of colonies of other lineages. It also alleviates ineffective erythropoiesis caused by cytokine deprivation, reduces apoptosis, and promotes cell proliferation[1].

BRAF inhibitors promoted the self-renewal of primary erythroid progenitors in vitro. The drug dose-response assay for UCB-CD34+-derived erythroid culture was conducted, with total cell numbers counted on Day 12. The graph illustrates the fold difference in proliferation between the GDC-treated and control (DMSO) groups on Day 12. The dashed line indicates the fold change for the control group. All experiments used control (DMSO), SB-590885 (HY-10966) at 1 μM, GDC-0879 (HY-50864) at 2 μM, and Encorafenib (HY-15605) at 0.5 μM.

Protocol
For proliferation assays, cells are treated with compounds in 0.1% DMSO and incubated for 72 hours at 37°C, 5% CO2. Viable cells are quantified using CellTiter-Glo reagent and luminescence detection on a Victor 2V plate reader. Cells are prepared for cell cycle analysis on a Becton Dickinson FACScan, according to the manufacturer's instructions. Data is acquired and analyzed using CellQuest v3.3 software. Anchorage-independent growth assays are done as described elsewhere, with inhibitors or DMSO vehicle included in the agar layer. Cultures are re-fed with media and inhibitor or DMSO every 5 to 7 days for a total of 28 days. Colonies are visualized and photographed by conventional light microscopy and quantified by counting on a grid in triplicate.
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
The pharmacokinetic properties and safety of SB-590885, following i.p. injection, are determined and 50 mg/kg daily injections are found to give therapeutic levels with minimal body weight changes. Tumors are initiated in 8- to 12-week-old female nude mice by s.c. injection of 5×106 A375P cells in Matrigel suspension, and 3 weeks after tumor induction when the tumors had reached a volume of 150 to 250 mm3, mice are randomized into groups of eight prior to treatment. Animals are treated with vehicle [2% N,N-dimethylacetamide, 2% Cremophor EL, and 96% acidified water (pH 4-5)], or vehicle containing 50 mg/kg of SB-590885 daily for 21 days. A cohort of mice treated with SB-590885 are then observed an additional 14 days following cessation of treatment. Tumor volume is measured for 55 days by calipers twice weekly.
