Neamine 是一种 Neomycin 的无毒衍生物，也是一种广谱氨基糖苷类抗生素。Neamine 是靶向血管生成素 (angiogenin) 的抗血管生成剂。Neamine 具有有效的抗菌，抗肿瘤和神经保护活性。
Neamine (0.625-25 μM; 48 hours; AsPC-1 cells) treatment inhibits ANG-mediated AsPC-1 cell proliferation in a dose-dependent manner in the range of 0.625-25 μM.
Neamine (100 μM) also blocks the nuclear translocation of ANG effectively.
Cell Proliferation Assay
| Cell Line: | AsPC-1 cells |
| Concentration: | 0.625 µM, 1.25 µM, 2.5 µM, 5 µM, 10 µM, 25 µM |
| Incubation Time: | 48 hours |
| Result: | Inhibited angiogenin (ANG)-induced AsPC-1 cells proliferation. |
Neamine (30-60 mg/kg; subcutaneous injection; daily; for 14 days; male Balb/c nude mice) has anti-tumor effects on AsPC-1 xenograft models. Neamine reduces the expression levels of ANG, Ki-67 and CD31 in tumor xenografts.
| Animal Model: | Male Balb/c nude mice (4 weeks old) injected with AsPC-1 cells |
| Dosage: | 30 mg/kg, 60 mg/kg |
| Administration: | Subcutaneous injection; daily; for 14 days |
| Result: | Had anti-tumor effects on AsPC-1 xenograft models. |
