AMXT-1501 tetrahydrochloride 是一种具有口服活性的多胺转运系统 (polyamine transport) 抑制剂。AMXT-1501 可阻断免疫活性小鼠中的肿瘤生长,但不能阻断缺乏 T 细胞无胸腺裸鼠中的肿瘤生长。DFMO 和 AMXT-1501 联合诱导 caspase-3 介导的 NB 细胞凋亡。
生物活性 | AMXT-1501 tetrahydrochloride is an orally activepolyamine transportinhibitor. AMXT1501 blocks tumor growth in immunocompetent mice but not in athymic nude mice lacking T cells[1]. Combination of DFMO and AMXT‐1501 induces caspase‐3 mediatedapoptosisin NB cell lines[2]. |

体外研究 (In Vitro) | AMXT-1501 tetrahydrochloride (0.39-50 μM; 48 hours) treatment exhibits cytotoxicity against this panel of NB cell lines (BE(2)-C, SMS-KCNR and SH-SY5Y cells), with IC50values of 17.72 μM for SMS-KCNR, 17.69 μM for BE(2)-C, and 14.13 μM for SH-SY5Y[2]. BE(2)‐C, SMS‐KCNR and SH‐SY5Y cells are exposed to AMXT-1501 tetrahydrochloride (2.5 μM) and DFMO (2.5 mM) alone or in combination (AMXT-1501 tetrahydrochloride 2.5 μM + DFMO 2.5 mM). After 96 hours exposure to AMXT-1501 tetrahydrochloride or DFMO does not significantly alter the level of noncleaved PARP, cleaved PARP and cleaved caspase 3, whereas cells treated with the combination of AMXT-1501 tetrahydrochloride with DFMO decrease the amount of noncleaved PARP and increase the amount of cleaved PARP and cleaved caspase 3[2].
Cell Viability Assay[2] Cell Line: | BE(2)‐C, SMS‐KCNR and SH‐SY5Y cells | Concentration: | 0.39 μM, 1 μM, 3.1 μM, 10 μM, 31 μM, 50 μM | Incubation Time: | 48 hours | Result: | AMXT-1501 tetrahydrochloride exhibited cytotoxicity against this panel of NB cell lines. |
Western Blot Analysis[2] Cell Line: | BE(2)‐C, SMS‐KCNR and SH‐SY5Y cells | Concentration: | 2.5 μM | Incubation Time: | 72 hours | Result: | Combination treatment with DFMO decreased the amount of noncleaved PARP and increased the amount of cleaved PARP and cleaved caspase 3 in all three cell lines. |

体内研究 (In Vivo) | AMXT-1501 tetrahydrochloride (3 mg/kg; subcutaneous injection; every day; 28 days) alone is sufficient to delay EAE onset moderately,but fails to protect animals from reaching the endpoint. However, the combination of DFMO and AMXT-1501 tetrahydrochloride are sufficient to deplete T cell polyamine pool, and consequently suppress T cell proliferation and effector function in vivo[3].
Animal Model: | C57BL/6 (WT) andODCknockout strain (ODCcKO) mice bearing experimental autoimmune encephalomyelitis (EAE) model[3] | Dosage: | 3 mg/kg | Administration: | Subcutaneous injection; every day; 28 days | Result: | Displayed a delayed disease onset initially, but eventually proceeded with pathologic development and reached the endpoint. |
