T297384687-43-4
Astragaloside IV (AS-IV), an active component isolated from Astragalus membranaceus, suppresses the activation of ERK1/2 and JNK, and downregulates matrix metalloproteases (MMP)-2, (MMP)-9 in MDA-MB-231 breast cancer cells. Astragaloside IV is a bioactive saponin first isolated from the dried plant roots of the genus Astragalus, which is used in traditional Chinese medicine.1 It dose-dependently inhibits human adenovirus type 3 (HAdV-3) in A549 cells (IC50 = 23 μM; LC50 = 865 μM).It inhibits replication of HAdV-3 and decreases HAdV-3-induced apoptosis. It has diverse protective effects for the cardiovascular, immune, digestive, and nervous systems. In particular, it reduces myocardial infarct size in dogs when administered prior to coronary ligation and reduces reperfusion arrhythmias in isolated rat hearts.

Bimiralisib (PI3K-IN-2) is an orally bioavailable pan inhibitor of PI3K and inhibitor of the mTOR, with potential antineoplastic activity. PI3K-IN-2 inhibits the PI3K kinase isoforms alpha, beta, gamma and delta and, to a lesser extent, mTOR kinase, which may result in tumor cell apoptosis and growth inhibition in cells overexpressing PI3K/mTOR. Activation of the PI3K/mTOR pathway promotes cell growth, survival, and resistance to both chemotherapy and radiotherapy.

Chemical Properties
| Description | GSK1838705A is an effective IGF-1R inhibitor (IC50: 2.0 nM), modestly potent to IR (IC50: 1.6 nM) and ALK (IC50: 0.5 nM), respectively, and little inhibition to other protein kinases. |
| Targets&IC50 | Insulin receptor:1.6 nM, IGF-1R:2 nM, ALK:0.5 nM |
| In vitro | In mice carrying COLO 205 tumors, GSK1838705A (30 mg/kg) inhibits 80% of tumor growth. Additionally, GSK1838705A demonstrates antitumor activity in mice with HT29 or BxPC3 xenografts. In mice with NIH-3T3/LISN tumors, GSK1838705A (60 mg/kg, p.o.) suppresses 77% of tumor growth without significant weight loss. It also momentarily doubles blood glucose levels by inhibiting IR signaling at a dose of 60 mg/kg. Furthermore, GSK1838705A (60 mg/kg) inhibits growth in established Karpas-299 xenografts by 93%, with no adverse effects on rat weight. |
| In vivo | GSK1838705A effectively inhibits the phosphorylation of IGF-1R (IC50: 85 nM) and IR (IC50: 79 nM) induced by ligands in cells. It demonstrates significant antiproliferative effects on various cell lines derived from solid and hematological tumors, such as L-82, SUP-M2, SK-ES, and MCF-7 (EC50: 24/28/141/203 nM). GSK1838705A induces the accumulation of MCF-7 and NCI-H929 cells in the G1 (2N) phase of the cell cycle. Additionally, it inhibits ALK (Ki: 0.35 nM) and the proliferation of cells expressing the NPM-ALK fusion protein (EC50: 24-88 nM). GSK1838705A significantly suppresses the phosphorylation of NPM-ALK in Karpas-299 and SR-786 cells, though it exhibits moderate effects on the phosphorylation of STAT3. |
| Kinase Assay | Kinase Assays: Baculovirus-expressed glutathione S-transferase-tagged proteins encoding the intracellular domain of IGF-1R (amino acids 957-1367) and IR (amino acids 979-1382) are used for determinations of IC50s by a homogeneous time-resolved fluorescence assay. A filter binding assay is used for appKi determinations using activated IGF-1R and IR kinases. Expanded kinase-selectivity profiling of GSK1838705A is carried out by screening the compound in the KinaseProfiler panel. |
| Cell Research | Cells are seeded in 96-well dishes, incubated overnight at 37 °C, and treated with DMSO or GSK1838705A for 72 hours. For the NIH-3T3/LISN proliferation assays, cells are seeded on collagen-coated 96-well tissue culture plates and allowed to adhere for 24 hours. The medium is replaced with serum-free medium and the cells are treated with GSK1838705A for 2 hour. Cells are incubated for 72 hours after addition of IGF-I (30 ng/mL). Cell proliferation is quantified using the CellTiter-Glo Luminescent Cell Viability Assay. IC50s are determined from cytotoxicity curves using a four-parameter curve fit software package (XLfit4(Only for Reference) |
