PF-04449613 is a phosphodiesterase 9A (PDE9A) inhibitor (IC50= 22 nM).1It is selective for PDE9A over PDE1C (IC50= >1,000 nM), as well as over a variety of other PDEs, inhibiting PDE2-8, -10, and -11 activity by less than 30% in a panel of enzymes, ion channels, and transporters at 1 μM but does inhibit the human dopamine transporter (DAT; Ki= 293 nM). PF-04449613 (0.1-100 mg/kg, s.c.) increases cerebrospinal fluid (CSF) levels of cyclic GMP (cGMP) in rats. Subcutaneous administration of PF-04449613 (10 mg/kg) increases the rate of dendritic spine formation and elimination in mouse primary motor cortex pyramidal neuronsin vivo.2It increases the average running speed of mice in an accelerating rotarod task, indicating improved motor learning, at the same dose. 1.Claffey, M.M., Helal, C.J., Verhoest, P.R., et al.Application of structure-based drug design and parallel chemistry to identify selective, brain penetrant, in vivo active phosphodiesterase 9A inhibitorsJ.

Pterine-6-carboxylic acid (6-Carboxypterin) 是叶酸的光降解产物，可被用作光敏感剂研究UVA 破环DNA 结构的分子机制。

Lirimilast（IC50 = 49 nM）是一种高效、选择性好且具有口服活性的磷酸二酯酶 4（PDE4）抑制剂 。Lirimilast具备显著的抗炎作用，可用于哮喘及慢性阻塞性肺疾病（COPD）相关研究。

Ac-SVVVRT-NH2 是一种调节PGC-1α启动子（human, 114%）活性的PGC-1α调节剂。该化合物能够在人皮下脂肪细胞中提高PGC-1α的mRNA水平（125%）和促进胞内脂质累积（128%）。因此，Ac-SVVVRT-NH2 对于研究PGC-1α调控的疾病具有潜在应用价值。

Acetyl hexapeptide 38 是一种乙酰化六肽，能显着刺激脂肪合成部位的使用，增加胸部或脸颊的体积，塑造完美身材

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.

Mitapivat (PKR-IN-1) 是口服具有活性的变构丙酮酸激酶 (pyruvate kinase) 激活剂，其AC50=20 nM。它在广泛的 PKLR 基因型中增加酶活性、蛋白质稳定性和 ATP 水平。它有潜在的恢复 PK 缺乏的糖酵解途径活性的作用。

DASA58 是一种有效的丙酮酸激酶M2 (PKM2) 活化剂，其中AC90=680 nM，AC50=38 nM。
