Immunopharmacology Comments
The sphingosine kinases (SPHK1 and SPHK2; SK1, SK2) are key enzymes within the sphingolipid metabolism pathway that promote tumour growth and pathologic inflammation. SK1-selective inhibitors include PF-543 [7-8]. Dual SK1/SK2 inhibitors include SLC4011540 [2], Compound 49 [1], MP-A08 [6] and SKI-II [4].
