Kinasechem的产品涉及绝大多数的信号通路研究以及癌症研究,包括: PI3K-Akt signaling pathway; MAPK signaling pathway; apoptosis(凋亡); DNA damage( DNA 损伤) RTK(受体酪氨酸激酶) 等
抑制剂在生命科学研究领域的应用非常广泛。在信号通路以及癌症研究方面,很多地方需要用到抑制剂来阻抑信号通路。
目前,在HIV的研究,抗感染,心血管疾病,老年痴呆症(阿兹海默症),甚至糖尿病的研究中,都会使用到抑制剂。
1、 抑制剂的一般使用方法:
(1)细胞实验
将抑制剂溶解于DMSO, 乙醇或者水中,稀释到需要的浓度。一般孵育48小时,也有孵育2周的实验。
(2)动物实验
小鼠模型:以注射为主。
大鼠模型:以口服为主。
(3)抗药性筛选实验
长期孵育,递增性增加浓度。
2、抑制剂的几个重要参数:
IC50(半抑制浓度)
指抑制剂降低对应激酶的活性到原来活性的一半的浓度。
IC50是抑制剂一个重要的指标,一般而言,IC50越小,抑制能力越强。
EC50
指加入抑制剂后,细胞死亡一半所需的浓度。
抑制剂选择性
抑制剂有多重抑制剂,指同时抑制多个靶点的抑制剂。有高选择性抑制剂,仅仅抑制某些激酶的某个亚型或者结构域。比如,有的抑制剂仅仅抑制PI3K这个激酶的gamma亚型。

In vitro | Febuxostat displays potent mixed-type inhibition of the activity of purified bovine milk XO, with Ki and Ki' values of 0.6 and 3.1 nM respectively. Febuxostat(TMX-67), a newly synthesized xanthine oxidase/xanthine dehydrogenase (XOD/XDH) inhibitor, has almost no effect on DNFB-sensitized mice.[1] At concentrations up to 100 muM, febuxostat has no significant effects on the activities of the following enzymes of purine and pyrimidine metabolism: guanine deaminase, hypoxanthine-guanine phosphoribosyltransferase, purine nucleoside phosphorylase, orotate phosphoribosyltransferase and orotidine-5'-monophosphate decarboxylase.[2] | |||||
In vivo | Febuxostat, at a daily dose of 80 mg or 120 mg, was more effective than allopurinol at the commonly used fixed daily dose of 300 mg in lowering serum urate.[3] Daily febuxostat doses in the range 10 mg to 120 mg resulted in proportional mean serum urate reductions ranging from 25% to 70% and in proportional increases in maximum febuxostat plasma concentrations and area under plasma concentration versus time curves.[4] | |||||
