clathrin mediated endocytosis (CME), moderately inhibits dynamin I (dynI) GTPase activity (IC50 45 μM) and transferrin (Tfn) endocytosis in U2OS cells (IC50 205 μM). Synthesis gave a new class of GTP-competitive dynamin inhibitors, the Sulfonadyns™. The introduction of a terminal cinnamyl moiety greatly enhanced dynI inhibition. Rigid diamine or amide links between the dansyl and cinnamyl moieties were
我们发现,dansylcadaverine ( 1 ) 是一种已知的网格蛋白介导的内吞作用 (CME) 细胞内抑制剂,可适度抑制 U2OS 细胞中的动力蛋白 I (dynI) GTP 酶活性 (IC 50 45 μM) 和转铁蛋白 (Tfn) 内吞作用 (IC 50 205 μM) )。合成了一类新型 GTP 竞争性动力抑制剂,Sulfonadyns™。末端肉桂基部分的引入极大地增强了 dynI 抑制。丹酰基和肉桂基部分之间的刚性二胺或酰胺连接不利于 dynI 抑制。体外抑制 dynI 活性的化合物 <10 id=15> 例如类似物33 (( E ) -N- (6-[(3-(4-溴苯基)-2-丙烯-1-基]氨基}己基) -5-异喹啉磺酰胺)) 和47 个(( E ) -N -(3-[3-(4-溴苯基)-2-丙烯-1-基]氨基}丙基)-1-萘磺酰胺)异构体,显示出 dyn IC 50 <4
