制备方法与用途

用途

NA-P-甲苯磺酰-L-精氨酸甲酯盐酸盐是丝氨酸蛋白酶的合成底物,因此被用于测定不同有机来源的丝氨酸蛋白酶。

制备

以L-精氨酸和对甲基苯磺酰氯为起始原料,在醇作为反应溶剂的情况下,可一步制备NA-P-甲苯磺酰-L-精氨酸甲酯盐酸盐。合成反应式如下图:

图1 NA-P-甲苯磺酰-L-精氨酸甲酯盐酸盐合成反应式

将L-精氨酸26.25g(0.25mol)和4mol/L氢氧化钠溶液62.5mL(0.25mol),加入装有机械搅拌、温度计、酸度计及滴加瓶的500mL四口烧瓶中,在冷阱中开启搅拌,使精氨酸和氢氧化钠反应完全。向四口烧瓶中加入2.7g四丁基硫酸氢铵和50mL水及甲醇以溶解相转移催化剂,然后在0℃以下缓慢滴加对甲基苯磺酰氯42.5mL(0.3mol)。后期不断滴加pH=9的硼酸缓冲溶液调节pH值保持在约9左右。待对甲基苯磺酰氯滴完后将温度升至15℃,继续搅拌反应3小时,并使用TLC检测反应是否完全。用乙醚洗涤(2×20mL),弃去醚层。在不断搅拌下缓慢滴加6mol/L盐酸调节水相pH值至2,继续搅拌20分钟后析出白色固体。乙酸乙酯萃取(3×30mL),分出乙酸乙酯有机层。用质量分数为5%氯化钠溶液和水洗涤直至中性,再用无水硫酸钠干燥,并旋蒸除去乙酸乙酯,得到油状液体。将此油状液体置于冰箱冷冻过夜后,析出大量白色固体,加入大量石油醚搅拌得白色粉末状固体。抽滤,以石油醚洗涤、干燥,最终获得NA-P-甲苯磺酰-L-精氨酸甲酯盐酸盐。

生物活性

TAME氢氯化物是后期促进复合体(APC/C或APC)的抑制剂,它与APC/C结合并阻止其通过Cdc20和Cdb激活,产生有丝分裂阻滞。

靶点
  • 有丝分裂阻滞调控:无APC底物时,TAME氢氯化物通过促进Cdc20在其N端区域的自泛素化来促使Cdc20从APC中释放。Cyclin B1拮抗TAME氢氯化物的效果,通过促进自由Cdc20与APC结合并抑制Cdc20的自泛素化。
体外研究
  • 细胞周期调控:TAME氢氯化物在Xenopus 细胞提取物中稳定Cyclin B1。首先,它减少了APC Cdc20/Cyclin B1复合物的kcat,而不影响Km,从而减慢未修饰Cyclin B1的初始泛素化速率。其次,在TAME氢氯化物存在下随着Cyclin B1被泛素化,其促进Cdc20与APC结合的能力减弱。结果是Cyclin B1泛素化在达到使其降解所需的阈值之前终止。
用途
  • 生化研究:用于丝氨酸蛋白酶的测定。
  • 其他用途:作为胰蛋白酶(trypsin)、凝血酶(thrombin)、血纤维蛋白溶酶(plasmin)和其他蛋白酶的底物。

    Purification and Characterization of Trypsin from the Spleen of Tongol Tuna (Thunnus tonggol)
    摘要:
    Trypsin from tongol tuna (Thunnus tonggol) spleen was purified to 402-fold by ammonium sulfate precipitation, followed by a series of chromatographic separations. The molecular mass of trypsin was estimated to be 24 kDa by size-exclusion chromatography and sodium dodecyl sulfate-polyacrylamide gel electrophoresis ( SDS- PAGE). Trypsin appearing as a single band on native PAGE showed the maximal activity at pH 8.5 and 65 degrees C. It was stable in a wide pH range of 6-11 but unstable at the temperatures greater than 50 degrees C. The enzyme required calcium ion for thermal stability. The activity was strongly inhibited by 1.0 g/L soybean trypsin inhibitor and 5 mM TLCK and partially inhibited by 2 mM ethylenediaminetetraacetic acid. Activity was lowered with an increasing NaCl concentration (0-30%). The enzyme had a K-m for N-alpha-p-tosyl-L-arginine methyl ester hydrochloride of 0.25 mM and a K cat of 200 s(-1). The N-terminal amino acid sequence of trypsin was determined as IVGGYECQAHSQPHQVSLNA and was very homologous to other trypsins.
