Product Introduction
Bioactivity
| 名称 | Pacritinib |
| 描述 | Pacritinib (SB1518) (SB1518) is an effective and specific inhibitor of JAK2 and FLT3 (IC50: 23/22 nM, in cell-free assays). |
| 细胞实验 | Cells are seeded at 30-50% confluency in 96-well plates and are treated with different concentrations of compounds (in triplicate) for 48 h. Cell viability is monitored using the CellTiter-Glo assay.(Only for Reference) |
| 激酶实验 | kinase activity assays: All assays are carried out in 384-well white microtiter plates. Compounds are 4-fold serially diluted in 8 steps, starting from 10 μM. The reaction mixture consisted of 25 μL assay buffer (50 mM HEPES pH 7.5, 10 mM MgCl2, 5 mM MnCl2, 1 mM DTT, 0.1 mM Na3VO4, 5 mM β-glycerol phosphate). For FLT3 assays, the reaction contains 2.0 μg/mL FLT3 enzyme, 5 μM of poly(Glu,Tyr) substrate and 4 μM of ATP. For JAK1 assays, the reaction contains 2.5 μg/mL of JAK1 enzyme, 10 μM of poly(Glu,Ala,Tyr) substrate and 1.0 μM of ATP. For JAK2 assays, the reaction contained 0.35 μg/mL of JAK2 enzyme, 10 μM of poly (Glu,Ala,Tyr) substrate and 0.15 μM of ATP. For JAK3 assays, the reaction contained 3.5 μg/mL of JAK3 enzyme, 10 μM of poly (Glu,Ala,Tyr) substrate and 6.0 μM of ATP. For TYK2 assays, the reaction contained 2.5 μg/mL of TYK2 enzyme, 10 μM of poly (Glu,Ala,Tyr) substrate and 0.15 μM of ATP. The reaction is incubated at room temperature for 2 h prior to addition of 13 μL PKLight? detection reagent. After 10 min incubation luminescent signals are read on a multi-label plate reader. |
| 体外活性 | Pacritinib is an effective inhibitor of both wild-type JAK2 and JAK2V617F mutant (IC50: 19 nM). The IC50s of Pacritinib are 50 nM for TYK2, 520 nM for JAK3 and 1280 nM for JAK1. Pacritinib effectively permeates cells to modulate signaling pathways downstream of JAK2, whether agonist activated or mutationally activated. Pacritinib induces apoptosis, cell cycle arrest and antiproliferative effects in JAK2WT- and JAK2V617F-dependent cells. Pacritinib inhibits cell proliferation of Karpas 1106P (IC50: 348 nM ) and Ba/F3-JAK2V617F (IC50: 160 nM ), respectively. Pacritinib inhibits endogenous colony growth derived from erythroid (IC50: 63 nM) and myeloid progenitors(IC50: 53 nM), respectively.[1] SB1518 also inhibits FLT3 and its mutant FLT3-D835Y (IC50: 6 nM ). Pacritinib inhibits FLT3 phosphorylation and downstream STAT, MAPK and PI3K signaling in FLT3-internal-tandem duplication (ITD), FLT3-wt cells and primary AML blast cells. Pacritinib treatment leads to a dose-dependent decrease of pFLT3, pSTAT5, pERK1/2 and pAkt in FLT3-ITD harboring MV4-11 cells with IC50 of 80, 40, 33 and 29 nM , respectively. Treatment of the primary AML blast cells with Pacritinib for 3 h leads to a dose-dependent decrease of pFLT3, pSTAT3 and pSTAT5 with an IC50 below 0.5 μM. Pacritinib induces apoptosis, cell cycle arrest and anti-proliferative effects in FLT3-mutant and FLT3-wt cells. Pacritinib inhibits cell proliferation of FLT3-ITD-harboring cells MV4-11 (IC50: 47 nM ) and primary AML blast (IC50: 0.19-1.3 nM ) cells. |
| 体内活性 | In JAK2V617F-dependent xenograft model, Pacritinib (150 mg/kg, p.o., q.d.) markedly ameliorates splenomegaly and hepatomegaly symptoms, with 60% normalization of spleen weight and 92% normalization of liver weight and is well tolerated without significant weight loss or any hematological toxicities, including thrombocytopenia and anemia. In JAK2V617F-dependent SET-2 xenograft model, Pacritinib dose-dependent inhibits tumor growth (40% for 75 mg/kg and 61% for 150 mg/kg).[1] Pacritinib treated once daily for 21 consecutive days, induces dose-dependent inhibition of tumor growth (38% for 25 mg/kg, 92% for 50 mg/kg and 121% for 100 mg/kg). Complete regression is observed in 3/10 and 8/8 mice for the 50 and 100 mg/kg/day groups, respectively. |

网络 第十九章 杂环化合物和生物碱 杂环化合物在自然界分布很广，其数量几乎占已知有机化合物的三分之一，用途也很多。许多重要的物质如叶绿素、血红素、核酸以及临床应用的一些有显著疗效的天然药物和合成药物等，都含有杂环化合物的结构。生物碱多是中草药的有效成分，绝大多数是含氮的杂环化合物。本章内容与医学关系密切，具有重要意义。
分子中具有高能键的化合物。在生物体内主要有上式（Ⅰ）和（Ⅱ）两种结构的高能化合物。其作用为贮藏能量（例如 ATP、肌酸磷酸）和作为产生 ATP源的中间代谢产物（例如磷酸烯醇丙酮酸）以及合成反应的中间物质（例如酰基辅酶 A），在蛋白质的结构（ conformation）变化周期的第一阶段上（例如钠钾 ATP酶的羧基磷酸中间体）也具有重要作用。多数高等化合物具有磷酸基，但也有例外。
由不同种元素组成的纯净物叫做化合物。化合物一般有固定的组成。化合物的组成一般可用化学式表示。化合物具有确定的物理性质和化学性质，不同于其组成元素的性质。化合物中的元素不能用简单的机械方法或物理方法分开，而必须用化学方法才能分离。
