用Y-33075盐酸盐(Y-39983,10μM)处理的视网膜神经节细胞(RGC)的神经突比未用Y-39983处理的RGC的神经突更长[2]。在不含钙离子的溶液中,由于组胺而收缩的兔纤毛动脉节段被 Y-33075 盐酸盐(Y-39983,1 μM)抑制。 Ca2+ 不受 Y-33075 盐酸盐 (10 μM) 的影响,并且在添加高钾 (高 k) 溶液时会上升 [3]。

与赋形剂组相比,局部给予0.05%Y-39983溶液显著增加了ONH兔的血流量。与给药前相比,0.05%Y-39983组在给药后90分钟的最大血流量增加为122.84±5.98%(平均值±标准误差)。与未经Y-39983处理的RGCs相比,经10μM Y-39983治疗的RGCs大鼠的神经延长。Y-39983在体内剂量依赖性地增加了具有再生轴突的RGCs的数量。10和100μM Y-39983处理的大鼠中具有再生轴突的RGCs数量分别为99.3±10.5和169.5±43.3个细胞/mm(2)(平均值±标准差),与盐水处理的大白鼠(43.3±6.0个细胞/mm2)相比显著增加。[1]
Y-27632和Y-39983都诱导了用高钾(高K)溶液预收缩的兔睫状动脉的浓度依赖性舒张。Y-27632和Y-39983诱导的舒张幅度不受100μM N(G)-硝基-L-精氨酸甲酯(L:-NAME)或10μM吲哚美辛的影响。在无钙溶液中,Y-27632和Y-39983显著抑制了10μM组胺诱导的睫状动脉瞬时收缩。然而,Y-27632和Y-39983均未影响高K溶液和组胺诱导的[Ca(2+)](i)升高。[2] |
| 动物实验 |
Blood flow in ONH was measured by the laser speckle method after topical administration of 0.05% Y-39983 solution or its vehicle in rabbit eyes. To investigate the effects of Y-39983 on axonal regeneration of RGCs, RGCs purified from rat eyes were cultured with or without 10 μM Y-39983 and morphologically observed by phase-contrast microscopy. Moreover, the effects of intravitreal administration of Y-39983 were evaluated using an in vivo model of axotomized RGCs in peripheral nerve-grafted rats.[1]
We measured in vitro ciliary artery smooth muscle contractions by isometric tension recordings and changes of intracellular free calcium concentration ([Ca(2+)](i)) by fluorescence photometry.[2] |

Purpose: To investigate the effects of Y-39983, a selective Rho-associated coiled coil-forming protein kinase inhibitor, on blood flow in the optic nerve head (ONH) in rabbits and axonal regeneration of retinal ganglion cells (RGCs) in rats.
Conclusion: Y-39983 may be a candidate drug not only for lowering of IOP but also for increasing of blood flow in ONH in the treatment of glaucoma. Moreover, Y-39983 may have therapeutic potential for axonal regeneration of RGCs in the treatment of diseases with degenerating axons of RGCs including glaucoma, although improvements of formulation or route of administration are needed in order to reach an effective concentration in retina.[1]
Purpose: In normotensive eyes, reduced ocular blood flow can lead to glaucoma pathogenesis. Drugs that reduce intraocular pressure (IOP) often cause vasodilation of the ciliary arteries and improve blood flow to the eye. A novel class of drugs called Rho-associated coiled coil-forming protein kinase (ROCK) inhibitors can lower IOP. Therefore, we tested the ability of two ROCK inhibitors, Y-27632 and Y39983, to relax rabbit ciliary arteries. Conclusions: We concluded that Y-27632 and Y-39983 relaxed isolated rabbit ciliary artery segments in vitro. The mechanism of relaxation was not dependent on endothelial-derived factors such as nitric oxide (NO) or prostacyclin, nor was it dependent on changes in intracellular Ca(2+) concentration.[2] |

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
计算结果:
工作液浓度: mg/mL;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL)。如该浓度超过该批次药物DMSO溶解度,请首先与我们联系。
