We report the identification and characterization of a novel lipid kinase that phosphorylates multiple substrates. This enzyme, which we term MuLK for multisubstrate lipid kinase, does not belong to a previously described lipid kinase family. MuLK has orthologs in many organisms and is broadly expressed in human tissues. Although predicted to be a soluble protein, MuLK co-fractionates with membranes and localizes to an internal membrane compartment. Recombinant MuLK phosphorylates diacylglycerol, ceramide, and 1-acylglycerol but not sphingosine. Although its affinity for diacylglycerol and ceramide are similar, MuLK exhibits a higher V-max toward diacylglycerol in vitro, consistent with it acting primarily as a diacylglycerol kinase. MuLK activity was inhibited by sphingosine and enhanced by cardiolipin. It was stimulated by calcium when magnesium concentrations were low and inhibited by calcium when magnesium concentrations were high. The effects of charged lipids and cations on MuLK activity in vitro suggest that its activity in vivo is tightly regulated by cellular conditions.
Disclosed are compounds of formula R—X—Y that may be used to inhibit the action of fatty acid amide hydrolase (FAAH). Inhibition of fatty acid amide hydrolase (FAAH) will slow the normal degradation and inactivation of endogenous cannabinoid ligands by FAAH hydrolysis and allow higher levels of those endogenous cannabinergic ligands to remain present. These higher levels of endocannabinoid ligands provide increased stimulation of the cannabinoid CB1i and CB2 receptors and produce physiological effects related to the activation of the cannabinoid receptors. They will also enhance the effects of other exogenous cannabinergic ligands and allow them to produce their effects at lower concentrations as compared to systems in which fatty acid amide hydrolase (FAAH) action is hot inhibited. Thus, a compound that inhibits the inactivation of endogenous cannabinoid ligands by fatty acid amide hydrolase (FAAH) may increase the levels of endocannabinoids and, thus, enhance the activation of cannabinoid receptors. Thus, the compound may not directly modulate the cannabinoid receptors but has the effect of indirectly stimulating the cannabinoid receptors by increasing the levels of endocannabinoid ligands. It may also enhance the effects and duration of action of other exogenous cannabinergic ligands that are administered in order to elicit a cannabinergic response.
