Thirteen derivatives of hydroxypyruvaldehyde phenylosazone were tested for effects on bovine erythrocyte membrane. Six drugs, including hydroxypyruvaldehyde phenylosazone itself and the o-CH3, m-CH3, p-CH3, o-Cl and p-Cl derivatives, increased the stability of bovine erythrocyte membrane to hypotonic shock ; the other derivatives with highter molecular weights were essentially without effect. Observations by scanning electron microscopy indicated that non-substituted, m-CH3 and o-Cl hydroxypyruvaldehyde phenylosazones caused extrusion of the erythrocyte surface, whereas o-CH3, p-CH3 and p-Cl derivatives caused invagination of the erythrocyte membrane. The p-Cl derivative can be adsorbed onto, or incorporated into the bovine erythrocyte membrane.
测试了羟基丙酮醛苯并噁唑酮的 13 种衍生物对牛红血球膜的影响。其中六种药物,包括羟基丙酮醛苯并噁唑酮本身以及邻氯丙烷、间氯丙烷、对氯丙烷、邻氯丙烷和对氯丙烷衍生物,都增加了牛红细胞膜对低渗休克的稳定性;其他分子量较高的衍生物基本上没有影响。扫描电子显微镜的观察结果表明,非取代的 m-CH3 和 o-Cl 羟基丙酮醛苯并噁唑酮会导致红细胞膜表面挤压,而 o-CH3、p-CH3 和 p-Cl 衍生物则会导致红细胞膜内陷。p-Cl 衍生物可吸附在牛红细胞膜上或与之结合。
