Polyacrylamide, Anion, Mw 18 million (PAM, Anion, Mw 18 million)，可用于合成水溶性聚合物，并作为生命科学研究相关的生物材料或有机化合物。

Berberine chloride (Natural Yellow 18) 是一种来自小檗科 Hydrastis canadensis L. 的生物碱，也存在于许多其他植物中，常用作抗生素。它对肠胃外的毒性相对较大，但已用于口服用于各种真菌和寄生虫感染以及止泻。

Berberine (Umbellatine) 属于生物碱类天然产物，可以激活 AMPK、抑制 DNA 拓扑异构酶、诱导 ROS 生成。Berberine 具有抗肿瘤、抗菌、降血糖、降血脂等生物学活性。

BW-180C (DADLE) 是水溶性的多肽类δ-阿片受体激动剂，也对 μ-阿片受体显示活性，在体内表现出镇痛活性。

DW18134 是一种白细胞介素受体相关激酶 4 (IRAK4) 的抑制剂，其IC50为11.2 nM。它能够抑制IRAK4和IKK的磷酸化过程，并降低TNF-α和IL-6的分泌。在小鼠模型中，DW18134 可减轻由Lipopolysaccharides诱导的腹膜炎和DSS诱导的结肠炎，并且有助于保护肠道屏障功能。

Alaproclate is a selective serotonin reuptake inhibitor (SSRI).1,2 It inhibits depletion of serotonin (5-HT) induced by 4-methyl-α-ethyl-m-tyramine in rat cerebral cortex, hippocampus, hypothalamus, and striatum (EC50s = 18, 4, 8, and 12 mg kg, respectively).1 Alaproclate inhibits NMDA-evoked currents and depolarization-induced voltage-dependent potassium currents in rat hippocampal neurons (IC50s = 1.1 and 6.9 μM, respectively) and does not inhibit GABA-evoked currents when used at concentrations up to 100 μM.2 It increases sirtuin 1 (SIRT1) levels in N2a murine neuroblastoma cells expressing apolipoprotein E4 (ApoE4; IC50 = 2.3 μM) and in the hippocampus in the FXFAD-ApoE4 transgenic mouse model of Alzheimer's disease when administered at a dose of 20 mg kg twice daily.3 Alaproclate (40 mg kg) decreases immobility time in the forced swim test in rats, indicating antidepressant-like activity.4References1.
