Paeoniflorin (Peoniflorin) 是从芍药根中提取的一种蒎烷单萜糖苷，具有抗癌作用、抗氧化应激、抗血小板聚集、血管扩张、降低血液粘度和抗炎活性等多种生物活性。它是一种热休克蛋白诱导剂，通过自噬途径保护 PC12 细胞免受 MPP+和酸性损伤。

H-89 是一种具有选择性和高效性的蛋白激酶 A 抑制剂（IC50：48 nM），是一种候选的心脏保护剂，可诱导大鼠的空间学习障碍，可用于研究心肌梗死。

Unifiram 是一种认知增强剂。 Unifiram 诱导大鼠海马 CA1 区场兴奋性突触后电位 (fEPSP) 幅度的持久增加 (EC50= 27 nM) 并增加大鼠大脑皮层中乙酰胆碱 (ACh) 的释放。

Tebuconazole-d9 is intended for use as an internal standard for the quantification of tebuconazole by GC- or LC-MS. Tebuconazole is a triazole fungicide that is active against both seed and foliar fungi. It inhibits 14α-demethylase isolated from U. maydis and S. bicolor with IC50 values of 0.05 and 0.16 nM, respectively. It inhibits the androgenic effect of the androgen receptor agonist DHT (IC20 = 2.89 µM) and is cytotoxic (EC20 = 38.9 µM) in an MDA-kb2 assay. Tebuconazole (50 and 100 mg kg per day) administered during gestation reduces testosterone levels and increases testicular levels of progesterone and 17α-hydroxyprogesterone in male rat fetuses. It has a feminizing effect on male pups and a virializing effect on female pups. When administered to rats gestationally through postnatal day 42, tebuconazole (20 and 60 mg kg per day) leads to cell death of pyramidal cells in the CA3-4 region of the hippocampus and layer V of the cortex concomitant with impairment in learning......
