PTC-209 是一种特定的BMI-1抑制剂,在 HEK293T 细胞系中的IC50为 0.5 μM。PTC-209 不可逆转地损害结直肠癌起始细胞 (CICs)。PTC-209 显示有效的抗骨髓瘤活性并损害肿瘤微环境。
生物活性 | PTC-209 is a specificBMI-1inhibitor with anIC50of 0.5 μM in HEK293T cell line. PTC-209 irreversibly impairs colorectal cancer-initiating cells (CICs). PTC-209 shows potent anti-myeloma activity and impairs the tumor microenvironment[1][2]. |
IC50& Target | IC50: 0.5 μM (BMI-1, in HT1080 tumor cells)[1] |
体外研究 (In Vitro) | PTC-209 (0.01-10 μM; 24-72 hours) induces a concentration- and time-dependent decrease in the cellular viability of all cell lines tested[2]. PTC-209 (1-2.5 μM) inhibits STAT3 phosphorylation in A549 lung cancer cells and MDA-MB-231 breast cancer cells[2].
Cell Viability Assay[2] Cell Line: | Lung (LNM35, A549 cells), breast (MDA-MB-231 and T47D cells), and colon (HT-29, HCT-116, and HCT8/S11 cells) | Concentration: | 0.01-10 μM | Incubation Time: | 24, 48, and 72 hour | Result: | Induced a concentration- and time-dependent decrease in the cellular viability of all cell lines tested. |
|
体内研究 (In Vivo) | PTC-209 (60 mg/kg body weight; subcutaneously; once a day for 11 days) significantly reduces tumor volume[1].
Animal Model: | Nude mice (male, aged 8-10 weeks, HCT1116 cell-derived tumor)[1] | Dosage: | 60 mg/kg body weight | Administration: | Subcutaneously; once a day for 11 days | Result: | Significantly reduced tumor volume |
