L-(+)-Ergothioneine

麦角硫因,Ergothioneine,L-(+)-Ergothioneine

Ergothioneine is an imidazole-2-thione derivative with orally active histidine betaine. Ergothioneine is a specific inhibitor of p38-MAPK and Akt, which plays a protective role in cell apoptosis induced by stress. Ergothioneine has antioxidant activity

  • 生物活性

    Data suggest that ET reacts at least 4-fold faster with 1O2 than ascorbic acid. ET must now be viewed as tightly linked with the GSH/GSSG redox couple. The necessary thiol foundation is present in all mammalian and vertebrate cells, and also in all species that generate ET, such as cyanobacteria, mycobacteria, and fungi. Regeneration provides a decisive advantage for ET over other reactive, but non-recoverable, compounds. Importance of ET for the eradication of noxious 1O2.

  • 不同实验动物依据体表面积的等效剂量转换表(数据来源于FDA指南)

    动物 A (mg/kg) = 动物 B (mg/kg)×动物 B的Km系数/动物 AKm系数


    例如,已知某工具药用于小鼠的剂量为88 mg/kg , 则用于大鼠的剂量换算方法:将88 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到该药物用于大鼠的等效剂量44 mg/kg。
