of 16 synthetic scramblase candidates were prepared from a tris(aminoethyl)amine (TREN) scaffold and evaluated for ability to facilitate translocation of fluorescent phospholipid probes across vesicle membranes and endogenous phosphatidylserine across the plasma membrane of nucleated cells. More than half of the compounds were found to greatly accelerate phospholipid translocation in vesicles. However
从三(氨基乙基)胺 (TREN) 支架中制备了一系列 16 种合成加扰酶候选物,并评估了促进荧光磷脂探针跨囊泡膜和内源性磷脂酰丝氨酸跨有核细胞质膜易位的能力。发现超过一半的化合物极大地加速了囊泡中的磷脂易位。然而,它们通常无法诱导有核哺乳动物细胞表面磷脂酰丝氨酸的量大幅增加,这与之前使用红细胞的结果形成对比。荧光显微镜显示合成的乱序快速从细胞质膜转运到内部细胞器的膜中。
