應用

使用N-p-甲苯磺酰基-L-苯丙氨酰甲基氯酮:
  • 研究转录因子NFκB是否参与肾胺酶抗体的表达
  • 检测NF-κB激活的作用
  • 研究其对胰凝乳蛋白酶的抑制作用

某些丝氨酸蛋白酶的不可逆抑制剂;用于抑制胰蛋白酶制剂中的胰凝乳蛋白酶。

生化/生理作用

N-p-甲苯磺酰基-L-苯丙氨酰甲基氯酮(TPCK)可阻断脂多糖(LPS)或核因子κB (NFκB)的细胞因子诱导的激活,进而阻断诱生型一氧化氮合酶(iNOS)和环氧化酶-2(COX-2)转录的诱导。阻断所有有丝分裂原对pp70s6k的激活。通过抑制半胱天冬酶在某些细胞系和某些刺激剂中的作用,阻断凋亡细胞系。还会阻断紫杉醇中引起的细胞凋亡(MCF-7人乳腺癌细胞中)。 ′TPCK识别胰凝乳蛋白酶中的苯丙氨酸残基并阻止其功能。
阻断LPS或细胞因子诱导的核因子κB (NFκB)激活,其反过来阻断iNOS和COX-2转录的诱导。阻断所有有丝分裂原激活 pp70s6k。通过抑制某些细胞的半胱天冬酶加工和某些刺激,进而阻断凋亡细胞。还能够阻断由紫杉醇(在MCF-7人乳腺癌细胞中)引发的细胞凋亡。
