PLX-4720(B-Raf(V600E) Inhibitor)是一种具有口服活性,高效的B-Raf(V600E) 特异性抑制剂,IC50为13 nM,且能抑制C-Raf-1 (Y340D/Y341D突变型),IC50为6.7 nM。 PLX-4720作用于B-Raf(V600E)比作用于野生型B-Raf(IC50, 160 nM)选择性高10倍;比作用于广谱的其他激酶如Frk, Src, Fak, FGFR和Aurora A(IC50s, 1.3-3.4 μM)选择性高100倍[1]。 PLX-4720能够诱导B-Raf(V600E)阳性的黑色素瘤细胞的细胞周期停滞和凋亡。另外,在B-Raf(V600E)阳性的移植瘤动物模型中,口服给药,PLX-4720显著延迟肿瘤生长,包括肿瘤衰退且且不会引起毒性[1]。 PLX-4720还能有效作用于人甲状腺肿瘤细胞系(8505c(B-Raf(V600E))和原代的正常甲状腺细胞(同时携带野生型B-Raf/突变型B-Raf(V600E)的杂合子),抑制细胞增殖,迁移以及侵袭能力。另外作用于原位移植人未分化甲状腺癌(ATC)(B-Raf(V600E))突变的小鼠模型,PLX-4720能明显移植肿瘤生长及转移[2]。

文献和实验Similar to the trypsin inhibitor, the chymotrypsin inhibitor also decreases protein degradability in the intestine, resulting in lower availability of amino acids and peptides for production purposes. This adversely affects growth
city directed primarily toward trypsin (Kunitz inhibitor), and (2) those that have a molecular weight of only 6000 to 10,000 Da with a high proportion of cystine residues and are capable of inhibiting chymotrypsin as well as trypsin at independent
-amylases of diverse origin. Three major groups of α-amylase have been characterized, based on molecular weight: 60,000, 24,000, and 12,500 Da. The inhibitor forms a complex with amylase. The complex formation can inactivate the amylase and in turn cause
