摘    要:目的:研究两组异构体(R,R)-XY-1到(R,R)-XY-12以及(S,S)-XY-1到(S,S)-XY-12对兔眼血流的影响。 方法:用彩色微球技术测量兔眼在高眼压下(40mmHg)各组织的血流情况。 结果:12个(R,R)-XY化合物以10g/L,50μL的剂量滴入兔眼,其中4个化合物可提高脉络膜血流。所有(S,S)-XY系列的化合物对兔眼血流没有影响。 结论:(R,R)-XY系列中一些化合物可以增加兔眼血流,这些可能对眼部血流降低相关疾病的防治有作用。在24个化合物中,(R,R)-XY-1和(R,R)-XY-9最有药效。

Abstract:AIM: To evaluate the effects of two series of enantiomers (R, R)-XY-1 through (R, R)-XY-12 and (S, S)-XY-1 through (S, S)-XY-12] on ocular blood flow in rabbits.
METHODS: Colored microsphere technique was used for in vivo experiments to determine the ocular blood flow in various tissues of ocular hypertensive (40mmHg) rabbit eyes.
RESULTS: Of the twelve compounds of (R, R)-XY series examined, four increased choroidal blood flow at 10g/L, 50μL instilled into eyes. All compounds of (S, S)- XY series were not effective on ocular blood flow.
CONCLUSION: Some compounds of (R, R)-XY series increased the ocular blood flow, which might be useful for the prevention and treatment of ocular blood flow related eye diseases. Among all twenty-four compounds, (R, R)-XY-1 and (R, R)-XY-9 seem to be the most potent ones.
Keywords:ocular blood flow  ischemia  enantiomer
