生物活性

GLYX-13 simultaneously enhanced the magnitude of long-term potentiation (LTP) of synaptic transmission, while reducing long-term depression (LTD). GLYX-13 reduced NMDA receptor-mediated synaptic currents in CA1 pyramidal neurons evoked by low frequency Schaffer collateral stimulation, but enhanced NMDAR currents during high frequency bursts of activity, and these actions were occluded by a saturating concentration of the glycine site agonist d-serine. GLYX-13 selectively enhanced burst-induced NMDAR-dependent spine Ca2+ influx and activation of burst-driven extrasynaptic NMDARs, with an action that was blocked by the NR2B-selective NMDAR antagonist ifenprodil. GLYX-13 may have unique therapeutic potential as a learning and memory enhancer because of its ability to simultaneously enhance LTP and suppress LTD. GLYX-13 is a new drug candidate with potential for the treatment of cognitive disorders. GLYX-13 may be a promising treatment for deficits in cognitive function associated with aging. GLYX-13 appears to exert its antidepressant effects in the frontal cortex via NMDAR-triggered synaptic plasticity. Understanding the mechanistic underpinning of GLYX-13's antidepressant action should provide both novel insights into the role of the glutamatergic system in depression and identify new targets for therapeutic development.

不同实验动物依据体表面积的等效剂量转换表(参考来源于公开文献

重量 (kg) 0.02 0.15 1.8 0.4 0.08 10
体表面积 (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km 系数 3 6 12 8 5 20
动物 A (mg/kg) = 动物 B (mg/kg) ×  动物 B的Km系数
动物 A的Km系数

例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
