of the 4-(phenylamino)quinazoline and -pyridopyrimidine classes of epidermal growth factor receptor (EGFR) inhibitors were prepared from the corresponding amino compounds by reaction with either acryloyl chloride/base or acrylic acid/1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride. All of the 6-acrylamides, but only the parent quinazoline 7-acrylamide, were irreversible inhibitors of the
通过与丙烯酰氯/碱或丙烯酸/丙烯酰胺反应,由相应的氨基化合物制备了一系列4-(苯基氨基)喹唑啉和-吡啶并嘧啶类表皮生长因子受体(EGFR)抑制剂的6-和7-丙烯酰胺衍生物。 1-(3-二甲基氨基丙基)-3-乙基碳二亚胺盐酸盐。所有6-丙烯酰胺,但仅母体喹唑啉7-丙烯酰胺,都是分离的酶的不可逆抑制剂,证实与酶结合时,前者的位置更好,可以与关键的半胱氨酸-773反应。喹唑啉,吡啶并[3,4-d]嘧啶和吡啶并[3,2-d]嘧啶6-丙烯酰胺都是不可逆的抑制剂,在酶分析中显示出相似的高效力(可能是由于可用酶的滴定)。但是吡啶[3,在针对A431细胞中EGFR的细胞自磷酸化分析中,2-d]嘧啶类似物的效力比其他类似物低2-6倍。喹唑啉总体上对抑制调蛋白刺激的erbB2自身磷酸化作用(在MDA-MB-453细胞中)总体上作用较小,而吡啶嘧啶则等价。在A431表皮样和H125非小细胞肺癌人肿瘤异种移植物中
