Definitions
- the present invention relates to derivatives and/or analogues of sphingosine and pharmaceutical compositions, including such derivatives and/or analogues, which are useful as drugs for the treatment of fungal infections, allergic diseases, immune disorders, etc.
- Sphingosine is a compound having the chemical structure shown in the general formula described below, in which Y 1 is hydrogen. It is known that various sphingo lipids, having sphingosine as a constituent, are widely distributed in the living body including on the surface of cell membranes of cells in the nervous system.
- a sphingolipid is one of the lipids having important roles in the living body.
- a disease called lipidosis is caused by accumulation of a specified sphingolipid in the body.
- Sphingolipids present on cell membranes function to regulate cell growth; participate in the development and differentiation of cells; function in nerves; are involved in the infection and malignancy of cells; etc. Many of the physiological roles of sphingolipids remain to be solved.
- ceramide a derivative of sphingosine, has an important role in the mechanism of cell signal transduction has been indicated, and studies about its effect on apoptosis and cell cycle have been reported.
- Sphingosine- 1 -phosphate is an important cellular metabolite, derived from ceramide that is synthesized de novo or as part of the sphingomeyeline cycle (in animals cells). It has also been found in insects, yeasts and plants.
- the enzyme, ceramidase acts upon ceramides to release sphingosine, which is phosphorylated by spingosine kinase, a ubiquitous enzyme in the cytosol and endoplasmic reticulum, to form sphingosine- 1 -phosphate.
- the reverse reaction can occur also by the action of sphingosine phosphatases, and the enzymes act in concert to control the cellular concentrations of the metabolite, which concentrations are always low. In plasma, such concentration can reach 0.2 to 0.9 ⁇ M, and the metabolite is found in association with the lipoproteins, especially the HDL.
- sphingosine- 1 -phosphate formation is an essential step in the catabolism of sphingoid bases.
- sphingosine- 1 -phosphate is a potent messenger molecule that perhaps uniquely operates both intra- and inter-cellularly, but with very different functions from ceramides and sphingosine.
- the balance between these various sphingolipid metabolites may be important for health.
- sphingosine- 1 -phosphate promotes cellular division (mitosis) as opposed to cell death (apoptosis), which it inhibits.
- mitosis mitochondria division
- apoptosis cell death
- Intracellularly it also functions to regulate calcium mobilization and cell growth in response to a variety of extracellular stimuli.
- sphingosine-1 -phosphate exerts many of its extra-cellular effects through interaction with five specific G protein-coupled receptors on cell surfaces. These are important for the growth of new blood vessels, vascular maturation, cardiac development and immunity, and for directed cell movement.
- Sphingosine-1 phosphate is stored in relatively high concentrations in human platelets, which lack the enzymes responsible for its catabolism, and it is released into the blood stream upon activation of physiological stimuli, such as growth factors, cytokines, and receptor agonists and antigens. It may also have a critical role in platelet aggregation and thrombosis and could aggravate cardiovascular disease.
- physiological stimuli such as growth factors, cytokines, and receptor agonists and antigens. It may also have a critical role in platelet aggregation and thrombosis and could aggravate cardiovascular disease.
- the relatively high concentration of the metabolite in high-density lipoproteins (HDL) may have beneficial implications for atherogenesis.
- sphingosine-1 -phosphate together with other lysolipids such as sphingosylphosphorylcholine and lysosulfatide, are responsible for the beneficial clinical effects of HDL by stimulating the production of the potent antiatherogenic signaling molecule nitric oxide by the vascular endothelium.
- lysophosphatidic acid it is a marker for certain types of cancer, and there is evidence that its role in cell division or proliferation may have an influence on the development of cancers.
- Fungi and plants have sphingolipids and the major sphingosine contained in these organisms has the formula described below. It is known that these lipids have important roles in the cell growth of fungi and plants, but details of the roles remain to be solved.
- derivatives of sphingolipids and their related compounds exhibit a variety of biological activities through inhibition or stimulation of the metabolism pathways.
- These compounds include inhibitors of protein kinase C, inducers of apoptosis, immuno-suppressive compounds, antifungal compounds, and the like. Substances having these biological activities are expected to be useful compounds for various diseases.
- the present invention provides a derivative or analogue of sphingosine that is able to regulate the functions of sphingolipid, and pharmaceutical compositions comprising said derivative or analogue.
