生物活性
Sordarin is an antifungal metabolite possessing a tetracyclic diterpene glycoside structure. It is a highly potent inhibitor of eukaryotic protein synthesis with selectivity for the fungal translation machinery. The elongation factor EF-2 is the molecular target for sordarin. It blocks ribosomal translocation by stabilizing the EF2-ribosome complex in a manner similar to that of fusidic acid in the bacterial system. Additional cellular components (including rpP0, which is an essential protein of the ribosomal large subunit stalk) are involved in its mechanism of action. Sordarin inhibitsin vitrotranslation in the pathogenic fungiC. albicans,C. glabrata, andC. neoformans. In addition to its therapeutic potential, sordarin is a useful tool for the analysis of protein translation events.

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）
| 小鼠 | 大鼠 | 兔 | 豚鼠 | 仓鼠 | 狗 |
| 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。
