Biochem/physiol Actions

PF-543 stimulates granular accumulation of microtubule-associated protein light chain 3 (LC3). It also induces LC3-I to LC3-II conversion, inhibited by autophagy inhibitors, wortmannin, 3-methyladenine (3-MA) and bafilomycin A1. In human head and neck squamous cell carcinoma (SCC) cells, PF-543 hydrochloride promotes necrosis,apoptosis and autophagy.
PF-543 hydrochloride is a novel, cell-permeable, potent and selective inhibitor of sphingosine kinase-1 (SphK1).
PF-543 hydrochloride is a novel, cell-permeable, potent and selective inhibitor of sphingosine kinase-1 (SphK1). PF-543 inhibits SphK1 with a Ki of 3.6 nM, is sphingosine competitive and is more than 100-fold selective for SphK1 over the SphK2 isoform. PF-543 decreased the level of endogenous S1P by 10-fold with proportional increase of the level of sphingosine.

Induction of autophagy by sphingosine kinase 1 inhibitor PF-543 in head and neck squamous cell carcinoma cells.

Preeclampsia (PE) involves inadequate placental function. This can occur due to elevated pro-inflammatory tumor necrosis factor-α (TNF-α). In other tissues, TNF-α signals via sphingosine kinase 1 (SphK1). SphK1 hinders syncytial formation. Whether this occurs downstream of TNF-α signaling is unclear.

Immune agonist antibodies (IAAs) are promising immunotherapies that target co-stimulatory receptors to induce potent anti-tumor immune responses, particularly when combined with checkpoint inhibitors. Unfortunately, their clinical translation is hampered by serious dose-limiting, immune-mediated toxicities, including high-grade and sometimes fatal liver
