22(S)-hydroxy Cholesterol is a synthetic oxysterol and a modulator of the liver X receptor (LXR). [1] t prevents monocyte chemoattractant protein 1 (MCP-1) expression induced by the LXR agonist GW 3965 in primary hepatocytes and downregulates mRNA expression of the LXR target genes CD36, ACSL1, and SCD-1 in human myotubes. It decreases triacylglycerol and diacylglycerol synthesis from labeled palmitate and acetate, respectively, in human myoblasts by 50% when used at a concentration of 10 uM. 22(S)-hydroxy Cholesterol also reduces fatty acid synthase (FAS) reporter activity through an LXR response element in the promoter region in COS-1 cells transfected with RXRα and LXRα and decreases the expression of MCP-1 and CCR2 in a mouse model of chronic ethanol consumption.[1] [2] Dietary supplementation of 22(S)-hydroxy cholesterol (30 mg/kg per day) leads to less body weight gain and lower liver triacylglycerol levels in rats when fed either a regular chow or high-fat diet as well as preven

Minaprine 是一种单胺氧化酶 MAO-A 可逆性抑制剂，对乙酰胆碱酯酶有微弱抑制，是一种抗抑郁类化合物。

PKCζ/ι偽基質抑制劑對PKC酶家族表現廣譜抑制作用，並可能促成記憶功能障礙。

Metaxalone-D6 is intended for use as an internal standard for the quantification of metaxalone by GC-or LC-MS. Metaxalone (T1610) is a skeletal muscle relaxant. It inhibits the proliferation of,and induces apoptosis in,RAW 264.7 cells in vitro when used at concentrations ranging from 1 to 100 µM. Metaxalone (T1610)also reduces LPS-induced increases in COX-1,COX-2,and NF-kB levels and inhibits LPS-induced production of TNF-α,IL-6,and prostaglandin E2 in RAW 264.7 cells. Formulations containing metaxalone have been used in the treatment of lower back pain.

NPD-001 is an effective inhibitor of TbrPDEB1. NPD-001 is 10-fold more potent on hPDE4 (hPDE4B1 IC50 = 0.6 nM) than on TbrPDEB1 (IC50 = 4 nM).

Sp-cAMPS triethylamine，一种 cAMP 类似物，是一种依赖 cAMP 的PKAI 和PKAII 的有效激活剂。Sp-cAMPS triethylamine 还是一种有效的竞争性磷酸二酯酶 (PDE3A) 抑制剂，Ki 为 47.6 µM。Sp-cAMPS triethylamine 以EC50为 40 μM 来结合PDE10GAF 域。

8-CPT-Cyclic AMP sodium是一种cAMP依赖性蛋白激酶(PKA)的激活剂和cAMP受体激活剂，也是一种cAMP特异性磷酸二酯酶(PDE VA)的抑制剂（IC50=0.9 μM），对PDE III和PDE IV的IC50分别为24和25μM。
