MK-0591, an analog of MK-886 is a potent and orally active leukotriene biosynthesis inhibitor with an IC50 value of 600 ng/ml. MK-0591(250 mg) nearly completely inhibited systemic leukotriene synthesis (>90%) in whole blood or in patients with active disease, and induced LTB4 synthesis in the target tissue of inflammation. [1]MK-0591 plays as a potential agent for the treatment of asthma and inflammatory bowel disease. MK-0591 specific interacted with 5-lipoxygenase, a membrane protein activating protein FLAP, which is essential for LT synthesis in inflammatory cells. [3]MK-0591 inhibited 96% production of LTB4 in whole blood and 91% that from BAL cells. By contrast, MK-0591 had no effect on airway hyper-responsiveness, ozone-induced bronchoconstriction, or influx of neutrophils into BAL. [4]References:1.Hillingsø J, Kjeldsen J, Laursen LS et al.

1、纳豆激酶是在纳豆发酵过程中由纳豆枯草杆菌(Bacillus subtilisl natto)产生的一种丝氨酸蛋白酶(单链多肽酶),分子量为27728道尔顿。
2、纳豆激酶在温度超过80℃时迅速变性失活,但反复冻融对其影响不大。
3、纳豆激酶在PH值从7升至12时,10min内稳定;PH值低于5时,迅速变性失活。胃酸环境中的PH值只有1.2到2之间,纳豆激酶根本无法通过。
4、纳豆激酶与粘性物质混合后,在PH值2-3的酸性环境中,还能保持不超过7.5%的活性。
5、纳豆激酶是大分子的单链多肽酶,可被肠道消化液(糜蛋白酶、胰蛋白酶、小肠液等)分解成氨基酸片段或分子量更小的肽链。
纳豆一词源于日本,是日本发酵食品,源自中国的咸豆豉,但并非中国豆豉,而是由黄豆通过纳豆菌(枯草杆菌)发酵制成豆制品,具有黏性,气味较臭,味道较甜,不仅保有黄豆的营养价值、富含维生素K2、提高蛋白质的消化吸收率,更重要的是发酵过程产生了多种生理活性物质,具有溶解体内纤维蛋白及其他调节生理机能的保健作用。
磷酸肌酸激酶(CPK),主要存在于骨骼肌和心肌,在脑组织中也存在,是参与体内的能量代谢的一种酶。在临床上主要用于诊断心肌梗塞。心肌梗塞患者发病后2-4小时,血液中此酶活动即开始升高。比血清中谷草转酸酶和乳酸脱氢酶的活力变化都出现得早。
临床意义:
(1)心肌梗塞后,CPK较谷草转氨酶和乳酸脱氢酶特异性高,但持续时间短,2-4天恢复正常。
(2)病毒性心肌炎,CPK也可升高,对诊断及预后有参考价值。
(3)进行性肌营养不良、多发性肌炎以及肌肉损伤时CPK也可升高。
(4)严重的心绞痛、心包炎、房颤、脑血管意外、脑膜炎以及心脏手术等,CPK可见升高。
根据PTK是否存在于细胞膜受体可将其分成受体型和非受体型。向左转|向右转
