Description

Ceramide kinase modulation
The present invention relates to modulators of ceramide kinase activity.
Sphingolipids have been considered as one of the major components of the cell membrane. Recent evidence has shown that, beyond their structural role, they can act as bioactive lipids and impact on signal transduction, in a way that is reminiscent of what is occurring with glycerophospholipids.
Physiological activity of sphingolipid metabolites include e.g. induction of apoptosis and stimulation of cell proliferation and it has been suggested that enzymes which metabolise sphingolipids are expected to participate in the induction of various diseases. For example
- ceramide which controls cell mechanisms has been suggested to be a regulator in the enzymatic reaction indicated above, e.g. it is reported that ceramide works as a second messenger of inflammatory cytokines, such as TNF-α and IL-1β, and activates arachidonic pathways, such as phospholipase A2; and ceramide or metabolites thereof thus may be considered as an exacerbating factor in inflammatory disorders;
- ceramide exacerbates the reduction of CD4+ T-cell accompanied by apoptosis and HIV infection of brain cells in patients infected with HIV,
- it is reported that TNF-α may cause insulin resistance in type 2 diabetes mellitus as a trigger and obesity and that ceramide is involved in the downregulation of TNF-α;
- it is disclosed that ceramide triggers septicemia caused by lipopolysaccharide;
- it is reported that the increase of ceramide activates sphingomyelinase in the aggregating reaction of LDL which triggers atherosclerosis lesions;
- it is known that ceramide promotes apoptosis of cancer cells in radiotherapy and chemotherapy;
- it was shown that ceramide regulation is involved in drug resistance of leukemia cells: a decrease of ceramide level is associated with the chemoresistant condition in leukemia.
Also ceramide-1 -phosphate (Cer-1-P), which is produced from ceramide by the action of ceramide kinase, e.g. by phosphorylation of the hydroxyl group at position 1 of various ceramide derivatives, e.g. including N-acylated-, such as N-hexanoyl-, N-octanoyl-, N- palmitoyl-D-erythro-sphingosine, shows physiological activities, e.g.
- Cer-1-P produced by ceramide kinase upon calcium stimulation is described to regulate the release of neuronal transmitters from brain synapses, and to modulate the action of ceramide kinase is thus expected to be of value in the treatment of various neuronal disorders, e.g. including Alzheimer's disease;
- Cer-1-P is believed to inhibit various normal ceramide activities, maybe through inhibition of acid sphingomyelinase and thus Cer-1-P is expected to modulate various disorders, e.g. inflammatory disorders, e.g. including chronic arthritis, HIV-infection, type 2 diabetes mellitus caused by insulin resistance as a trigger, obesity, septicemia and atherosclerosis; it is believed that such diseases may be treated by modulation of ceramide kinase;
- Cer-1-P is believed to act primarily inside the cell where it facilitates vesicle transport. It has been implicated in phagocytosis, and therefore could play an important role during inflammation processes;
- the mitogenic activity of exogenously added Cer-1-P has also been shown. Therefore, this sphingolipid metabolite may be relevant to cell proliferation disorders, including but not limited to cancer and psoriasis.
- Cer-1-P has been reported to mediate cytokine- and calcium ionophore-induced arachidonic release, and it is further indicated that C-1-P may directly activate cytosolic PLA2; and this further evidences the possible role of Cer-1-P in inflammatory disorders;
- Cer-1-P levels may also be relevant to the pathophysiology (e.g. susceptibility to retinitis pigmentosa) of the visual system.
Now surprisingly compounds which modulate, e.g. inhibit, ceramide kinase activity are provided.

Ceramide kinase overexpressing cells exhibit enhanced sensitivity to ceramide-mediated apoptosis. This is a direct consequence of ceramide kinase activity. Thus, inhibitors of ceramide kinase are capable of reverting this enhanced sensitivity back to the usual level found in parental cells (i.e. not overexpressing ceramide kinase). Accordingly, compounds inactive towards ceramide kinase have no effect in this assay

In vitro Ceramide Kinase Assay
That assay is performed on recombinant GST-His-CerK produced in insect cells and purified to 90% using single step chromatography on Nickel-agarose. The purified protein is frozen in aliquots containing 0.5 mg/ml GST-His-CerK in 10 mM MOPS, pH7.2, 300 mM KCI, 500 mM imidazole, 2.5 mM DTT, 5% Glycerol, 0.01% Triton X-100.
CerK activity assays are performed in total volumes of 100 μl with the following components (final concentrations): 180 μM Λ/-octanoyl-sphingosine (C8-ceramide), 1 mM cardiolipin, 1.5% β-octylglucoside, 0.2 mM DETAPAC, 20 mM MOPS, pH 7.2, 50 mM NaCI1 1 mM DTT, 2 mM EGTA, 3 mM CaCI2, 500 μM (γ-32P)ATP (40-100 mCi/mmol). Reactions are started by addition of protein samples (20 μl/assay). The final GST-His-CerK protein concentration in the assays was 40 ng/μl. Compounds stock solutions were prepared in DMSO at 10 mM and diluted in assay mixes (final DMSO concentration was 1%). Incubations are carried out for 15 min at 300C. Reactions are stopped by adding 1 ml of chloroform/methanol 1 :1 and 430 μl 1M KCI in 20 mM MOPS pH 7.2. 400 μl of the organic phase are removed, further extracted with 300 μl 1M KCI in 20 mM MOPS pH 7.2. After vortexing followed by short centrifugation, 200 μl of the organic phase are removed and counted directly. Ceramide-1- phosphate is the only phosphorylated product detectable in the final organic phase under these conditions.
Cell-based Ceramide Kinase Assay
Control COS-1 cells in 24-well plates or COS-1 cells stably overexpressing ceramide kinase, are treated with fluorescent NBD labeled C6-ceramide for 3 hr in 10% serum-containing DMEM medium. Subsequently, cells are washed with 500 μl of HBSS supplemented with 10 mM of EDTA. Lipids are extracted with 100 μl of CH3OH. After transfer in Eppendorf tubes, 100 μl of CHCI3 are added as well as 150 μl of HBSS/EDTA. After vortexing and short centrifugation, the organic phase is collected and dried out using a speed-vac. The dried lipids are finally dissolved into CHCI3ZCH3OH and processed with thin layer chromatography analysis using butanol/acetic acid/water 3:1 :1 as the eluent. Compounds prepared at 10 mM in DMSO are diluted directly into the cell culture medium to reach the appropriate concentrations. DMSO is used as a vehicle control.
The EC50 in the above described assays is determined by use of different concentration ranges of the compounds tested. The activity obtained without compound is set at 100%.
