常见问题列表
生物活性
Rottlerin (Mallotoxin, NSC 56346, NSC 94525)是一种从 Mallotus Philippinensis 纯化出来的天然化合物，一种特效的 Protein kinase 的抑制剂，对PKCδ(来自杆状病毒感染的Sf9昆虫细胞)、PKCδ(来自猪脾)和CaM kinase III的IC50值分别为3 μM、6 μM和5.3 μM。Rottlerin 还可以抑制PKCα、PKCγ、PKCβ、PKCη、CKII和PKA，其IC50值分别为30 μM、40 μM、42 μM、82 μM、30 μM和78 μM。靶点

体外研究
Rottlerin (20 μM, 2/6/24 hours) dramatically decreases the cyclin D-1 mRNA levels in a time-dependent manner in primary HMVEC.
Rottlerin (20 μM) exhibits cell proliferation in HMVEC.
Western Blot Analysis
| Cell Line: | Primary HMVEC (Human Microvascular Endothelial Cell). |
| Concentration: | 20 μM. |
| Incubation Time: | 2, 6, 24 hours. |
| Result: | Dramatically decreased the cyclin D-1 mRNA levels in a time-dependent manner. After 2 h of treatment, the mRNA level was reduced to 50% of the control, to circa 40% after 6 h, and to 20% after 24 h. Consistently, a similar trend was observed in the protein levels, where the decrease was circa 50% after 2 h, 80% after 6 h, and to almost undetectable levels after 24 h. |
Cell Proliferation Assay
| Cell Line: | Primary HMVEC (Human Microvascular Endothelial Cell). |
| Concentration: | 20 μM. |
| Incubation Time: | 24/48 hours. |
| Result: | Exhibited a strong growth inhibition, with a reduction in thymidine incorporation respect to the control cells (DMSO 0.1%) of circa 75% and 80%, respectively. |
体内研究
Rottlerin (20 mg/kg, gavage 5 days per week, once daily, for 6 weeks) inhibits AsPC-1 pancreatic tumor growth in Balb C nude mice with no toxicity.
Rottlerin inhibits tumor cell proliferation, and induces apoptosis through activation of caspase-3 and cleavage of poly(ADP-ribose) polymerase (PARP).
| Animal Model: | Balb C nude mice (4-6 weeks old) with AsPC-1 cells (2×10 6 cells mixed with Matrigel, 50:50 ratio) injection. |
| Dosage: | 0 or 20 mg/kg. |
| Administration: | Gavage 5 days per week, once daily, for 6 weeks. |
| Result: | Inhibited AsPC-1 pancreatic tumor growth in Balb C nude mice and had no effect on the body weight of AsPC-1 tumor-bearing mice. |
