ASR-490 reduces the viability of HCT116 and SW620 cells by downregulating Notch1 signaling. ASR-490 overcomes Notch1 overexpression and inhibits the growth of HCT/Notch1 transfectants. ASR-490 inhibits the tumor growth in control (pCMV/HCT116) and Notch1/HCT116 in xenotransplanted mice In Vitro ASR-490 (0-1.6 µM; 24 h, 48 h) reduces the viability of HCT116 and SW620 cells in 24h (IC 50 =750 nM in HCT116 cells, IC 50 =1.2 µM in SW620 cells) and 48h (IC 50 =600 nM in HCT116 cells, IC 50 =850 nM in SW620 cells).\nASR-490 (750 nM in HCT116 cells and 1.2 µM in SW620 cells, 24 h) shows apoptotic cell death and upregulation of the proapoptotic markers Bax and cleaved PARP Expression; inhibits the capability of colorectal cancer cells.\nASR-490 (HCT116 cells; 750 nM in 24 h, 600 nM in 48 h) overcomes Notch1 overexpression and inhibits the growth of HCT/Notch1 transfectants. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Cell Viability AssayCell Line: HCT116, SW620 cells Concentration: 0-1.6 µM Incubation Time: 24 h, 48 h Result: Reduced the viability of HCT116 and SW620 cells in 24h (IC 50 =750 nM in HCT116 cells, IC 50 =1.2 µM in SW620 cells) and 48h (IC 50 =600 nM in HCT116 cells, IC 50 =850 nM in SW620 cells). Apoptosis AnalysisCell Line: HCT116, SW620 cells Concentration: 750 nM in HCT116 cells and 1.2 µM in SW620 cells Incubation Time: 24 h Result: Showed apoptotic cell death and upregulation the proapoptotic markers Bax and cleaved PARP\nExpression, inhibited the capability of colorectal cancer cells. Cell Proliferation AssayCell Line: HCT116 cells Concentration: 750 nM in 24 h, 600 nM in 48 h Incubation Time: 24 h, 48 h Result: Overcome Notch1 overexpression and inhibited the growth of HCT/Notch1 transfectants. In Vivo ASR-490 (5 mg/kg; i.p.; thrice a week for 4 weeks) inhibits the tumor growth in control (pCMV/HCT116) and Notch1/HCT116 in xenotransplanted mice . MCE has not independently confirmed the accuracy of these methods. They are for reference only.
