名稱 | Nuciferine |
描述 | Nuciferine ((-)-Nuciferine) is an alkaloid found within the plants Nymphaea caerulea and Nelumbo nucifera. It has a profile of action associated with dopamine receptor blockade. |
細胞實驗 | Nuciferine is dissolved in DMSO and stored, and then diluted with appropriate medium before use[1]. Cells are plated into 48-well plates one day before uptake is performed. Cells are washed with 0.5 mL uptake buffer (4 mM Tris, 6.25 mM HEPES, 120 mM NaCl, 5 mM KCl, 1.2 mM CaCl2, 1.2 mM MgSO4, 5.6 mM D-glucose, 1.7 mM ascorbic acid, and 1 μM pargyline, pH 7.4). Cells are incubated with 225 μL uptake buffer with or without the indicated concentration of Nuciferine for 15 minutes. After incubation, 25 μL uptake buffer containing 3H-DA and DA is added for a final concentration of 20 nM 3H-DA and 1 μM DA. Cells are incubated at 37°C for 20 minutes or for the time indicated. Nonspecific uptake is determined in the presence of 10 μM nomifensine. Uptake is terminated by aspirating uptake buffer and washing each well twice with 0.5 mL ice-cold uptake buffer. Cells are lysed in 0.1 N NaOH and transferred to vials containing 3 mL scintillation cocktail. Radioactivity is quantitated using a Beckman LS6500 counter. Data are analyzed in Graph Pad Prism 5.0[1]. |
激酶實驗 | For affinity determination, Nuciferine is subjected to primary radioligand binding assays tested at a single 10 μM concentration to displace 50% of the radioligand at a given receptor target. If a more than 50% of the radioligand is displaced, Nuciferine is selected for a secondary binding assay tested at 11 concentrations in triplicate in competition with the radioligand to generate an IC50 and Ki. Binding assays are performed in 96-well plates with 125 μL per well in appropriate binding buffer using radioligand at or near the Kd. Plates are incubated at room temperature in the dark for 90 min. Reactions are stopped by vacuum filtrations onto 0.3% polyethyleneimine soaked 96-well filter mats using a 96-well Filtermate harvester, followed by at least three washes of cold wash buffer. Scintillation cocktail is melted onto dried filters and radioactivity is counted using a Wallac Trilux Microbeta[1]. |
體外活性 | Nuciferine在DD2受體上作為部分激動劑,其活性(Emax=67%的多巴胺)與阿立哌唑(Emax=50%的多巴胺)類似。根據(jù)其部分激動劑活性,Nuciferine能夠抑制由多巴胺誘導(dǎo)的Gi激活,其效力與氯氮平相近(Nuciferine KB=62 nM; 氯氮平KB=20 nM),此通過Schild回歸分析確定[1]。作為一種天然產(chǎn)品,Nuciferine能有效抑制成年蠕蟲的活動性。Nuciferine可有效抑制成年血吸蟲的基礎(chǔ)及5-HT誘導(dǎo)的運動性。對于Sm.5HTRL和血吸蟲幼蟲,Nuciferine的抑制濃度分別為0.24±0.04 μM和0.62±0.22 μM[2]。 |
體內(nèi)活性 | 在與抗精神病化合物作用相關(guān)的嚙齒動物模型中,Nuciferine阻斷了頭頸擺動反應(yīng)和5-HT2A激動劑的辨別刺激效果,取代了氯氮平的辨別刺激,增強了安非他明引起的運動活性,抑制了苯環(huán)利定(PCP)引起的運動活性,并在不引起僵直的情況下挽救了PCP引起的前脈沖抑制中斷。在1或3 mg/kg Nuciferine存在下,累積的PCP劑量產(chǎn)生的效果與單獨使用PCP相似。在訓(xùn)練有識別氯氮平的動物中,10 mg/kg Nuciferine表現(xiàn)出對1.25 mg/kg氯氮平的劑量依賴性替代(80.63%的藥物杠桿反應(yīng)),其ED50值為5.42 mg/kg(95% CI 3.09-9.48 mg/kg),而測試的較低劑量(0.1 mg/kg-3 mg/kg)未能產(chǎn)生對氯氮平辨別線索的替代。除了在適當(dāng)?shù)穆鹊礁軛U上有較高百分比的反應(yīng)外,與對照組相比,10 mg/kg Nuciferine還顯著抑制了反應(yīng)速率(p<0.001)[1]。 |
存儲條件 | Powder: -20°C for 3 years | In solvent: -80°C for 1 year | Shipping with blue ice. |
溶解度 | DMSO : 2.95 mg/mL (10 mM), Sonication is recommended. |
