SMS2-IN-1 是一种有效且具有高选择性的鞘磷脂合成酶 2 (SMS2) 抑制剂， IC50 为 6.5 nM，Kd 为 37 nM。SMS2-IN-1 对 SMS2 的选择性比 SMS1 (IC50 为 1000 nM) 多 150 倍。

ML299 (VU0463568) 是一种有效的 DHCR7 抑制剂。 DHCR7 是胆固醇生物合成中的一种酶。 是一种磷脂酶 D1和磷脂酶 D2的选择性变构调节剂和双重抑制剂 (IC50值分别为 6 和 12 nM)，能够抑制 U87-MG 胶质母细胞瘤细胞的侵袭性迁移。

ROC-0929 (compound 13a) is a potent and selective inhibitor of secreted phospholipases A2 (sPLA2s), effectively targeting hGX with an IC50 of 80 nM. It efficiently inhibits the phosphorylation of ERK1/2 and p-38. sPLA2s, belonging to the disulfide-rich, Ca2+-dependent enzyme family, catalyze the hydrolysis of glycero-phospholipids at the sn-2 position, resulting in the release of a fatty acid and a lysophospholipid. ROC-0929 holds promise in researching inflammation-related diseases.

3'-sulfo Galactosylsphingosine is a form of sulfatide that is lacking the fatty acyl group. It decreases migration and adhesion of B35 neuroblastoma cells and increases cell rounding when used at a concentration of 20 μM. It also inhibits PKC and cytochrome c oxidase activity when used at concentrations of 150 and 50-100 μM, respectively. 3'-sulfo Galactosylsphingosine accumulates in patients with metachromatic leukodystrophy, a lysosomal storage disorder characterized by arylsulfatase A (ASA) deficiency leading to progressive demyelination and neuromotor deficits. In mice lacking ASA, levels of 3'-sulfo galactosylsphingosine increase after one month of age followed by demyelination and neuromotor deficits. 3'-sulfo Galactosylsphingosine has been used as a standard for the quantification of 3'-sulfo galactosylsphingosine by LC-MS.

Ro 23-9358 是一种具抗炎特性的强效分泌型磷脂酶 A2 抑制剂。

The group IVA phospholipase A2 (PLA2), known as calcium-dependent cytosolic PLA2 (cPLA2), selectively releases arachidonic acid (AA) from membrane phospholipids, playing a central role in initiating the synthesis of prostaglandins (PGs) and leukotrienes (LTs). Pyrrophenone inhibits cPLA2α with an IC50 of 4.2 nM in enzyme assays and potently blocks the release of AA and the production of PGE2 and LTC4 in cells (IC50 = 24, 25, and 14 nM, respectively). Its action is reversible and selective, as pyrrophenone inhibits the secretory type IB and IIA PLA2s with more than a hundred-fold less potency. Pyrrophenone has also been shown to inhibit calcium ionophore (A23187)-stimulated AA release from monocytic cells, interleukin-1-induced PGE2 synthesis in mesangial cells, and the production of PGE2, LTs, and platelet-activating factor by human neutrophils, always with maximal inhibition at concentrations below 1 μM.
