Apexbio Technology LLC CH5138303 959763-06-5 10mM (in 1mL DMSO)
CH5138303 (CAS 959763-06-5) is a potent inhibitor targeting Heat Shock Protein 90 (HSP90) exhibiting strong binding affinity with a Kd of 0 48 nM HSP90 a molecular chaperone regulates protein folding stability and degradation and maintains oncogenic proteins crucial to tumor cell proliferation CH5138303 effectively reduces protein levels and phosphorylation of HSP90 client proteins including Raf1 AKT EGFR and HER2 in NCI-N87 cancer cells In animal studies using human gastric cancer NCI-N87 xenografts oral administration of CH5138303 demonstrates significant antitumor activity achieving a tumor growth inhibition (TGI) rate of 136% at an ED of 3 9 mg/kg
Apexbio Technology LLC GW4064 278779-30-9 10mM (in 1mL DMSO)
GW4064 (CAS 278779-30-9) is a non-steroidal agonist targeting the farnesoid X receptor (FXR) a nuclear receptor involved in lipid and cholesterol regulation Reported EC50 values of GW4064 for FXR activation are approximately 15 nM in isolated receptor assays and 90 nM in human FXR-transfected cell studies In animal models including KK-Ay and ob/ob mice GW4064 administration was associated with reduced serum triglyceride (TG) concentrations and diminished very-low-density lipoprotein (VLDL) production However due to limitations such as poor solubility chemical instability under UV exposure and a potentially toxic stilbene pharmacophore GW4064 primarily serves as a research tool for investigating FXR signaling pathways
