一般描述

苯甲基磺酰氟(PMSF)是一种广泛使用的丝氨酸蛋白酶抑制剂，可有效抑制胰凝乳蛋白酶、凝血酶和胰蛋白酶等酶。 PMSF通过磺化丝氨酸蛋白酶反应位点的丝氨酸残基中的羟基残基，发挥抑制作用。

应用

PMSF常用在裂解缓冲液中，通过抑制蛋白酶、避免其在细胞或组织裂解后降解，从而在蛋白分离和样品制备过程中保留目标蛋白。 PMSF在水溶性培养基中不稳定。 因此，在水溶性培养基中使用前，通常采用无水有机溶剂（例如100％乙醇或无水异丙醇）制备PMSF储备溶液。

PMSF的常见特性和优点包括：
  • 抑制丝氨酸蛋白酶，如胰蛋白酶和胰凝乳蛋白酶
  • 同时还可抑制半胱氨酸蛋白酶（通过还原硫醇可逆）和哺乳动物的乙酰胆碱酯酶
  • 有效性和毒性均不及DFP
  • 有效浓度0.1-1 mM。
  • pH 7.5时半衰期 = 1小时。
苯基甲磺酰氟已用于以下应用：
  • 细胞分级分离。
  • 在核蛋白提取中作为补充剂。
  • 胆固醇酯酶（CE）和假胆碱酯酶（PCE）抑制剂。
  • 在离心之前用于血液的收集以量化血浆ANP的水平。

生化/生理作用

PMSF的摄入将产生与其抗胆碱酯酶作用无关的镇痛作用，并延长中枢给药的β-内啡肽的镇痛作用。

In BRAF(V600)-mutant tumours, most mechanisms of resistance to drugs that target the BRAF and/or MEK kinases rely on reactivation of the RAS-RAF-MEK-ERK mitogen-activated protein kinase (MAPK) signal transduction pathway, on activation of the alternative, PI(3)K-AKT-mTOR, pathway (which is ERK independent)

Hypoxia-inducible factors (HIFs) are oxygen-sensitive transcription factors. HIF-1α plays a prominent role in hypoxic gene induction. HIF-2α target genes are more restricted but include erythropoietin (Epo), one of the most highly hypoxia-inducible genes in mammals. We previously reported that HIF-2α
