Definitions
- the invention relates to a thermolabile liposome with a regulated release temperature for the liposome content, in particular a liposome stable at 37 ° C. in serum with a regulated release temperature between 40 and 80 ° C.
- Liposomes are artificially formed vesicles from lipid bilayers which enclose an aqueous compartment (Bangham et al., 1 965). Originally used as a model system for a cell membrane, liposomes have recently been further developed primarily for the transport of drugs. Liposomes can increase the tolerability of active ingredients (reduction of the active toxicity of amphothericin B by liposomal formulation (AmBisome ® ) by a factor of 75 (Proffitt et al., 1 991)). However, they also open up the possibility of specifically transporting medicinal substances into diseased tissue (Forssen et al., 1 992).
- liposomes are mainly taken up in cells of the reticuloendothelial system (RES) of the liver and spleen (Gregoriadis and Nerunhun, 1 974).
- RES reticuloendothelial system
- spleen a reticuloendothelial system
- tumors which are often very well vascularized (Jain, 1 996) and whose vessels are particularly permeable due to widened interendothelial connections, a large number of fenestrations and discontinuous basement membranes (Murray and Carmichael, 1 995), the probability of uptake would increase This massively increases liposomes.
- the invention is therefore based on the object of providing a liposome which has a significantly improved half-life in serum compared to the usual half-life of known liposomes in the order of 4 hours, and which is such that the content of the liposomes is at a certain temperature is released quickly.
- a liposome with a regulated release temperature for the liposome content which is characterized in that it consists essentially of at least one phosphatidylcholine with a main transition temperature in the range from 0 to 80 ° C and more than 15 to 70 wt. -% Phosphatidyloligoglycerin is formed.
- a liposome with a regulated release temperature for the liposome content which is characterized in that it consists essentially of at least one phosphatidylcholine with a main transition temperature in the range from 0 to 80 ° C and more than 15 to 70 wt. -% Phosphatidyloligoglycerin is formed.
- the liposomes according to the invention additionally contain smaller amounts Alkylphosphocholines, preferably 10 to 15% by weight.
- Suitable substances include hexadecylphosphocholine, oleylphosphocholine and ether lysolecithins.
- the hydroxyl group in position 2 of the glycerol can be methylated or free.
- the alkylphosphocholines have an antitumor effect due to temperature-dependent release from the liposomes.
- Liposomes constructed according to the invention have significantly improved half-lives of up to more than 25 hours in the serum and can, by suitable selection of the components and amounts of the components depending on their main transition temperature, release the ingredient (s) quickly and completely at a predetermined temperature ,
- the liposome according to the invention is preferred from about 20 to 75% by weight dipalmitoyl lecithin (1, 2-dipalmitoylglycero-3-phosphocholine), about 10 to 25% by weight distearoyl lecithin (1, 2-distearoylglycero-3-phosphocholine) and more than 15 to about 50 wt .-% dipalmitoylphosphoglyceroglycerin composed.
- dipalmitoyl lecithin 1, 2-dipalmitoylglycero-3-phosphocholine
- distearoyl lecithin 1, 2-distearoylglycero-3-phosphocholine
- dipalmitoylphosphoglyceroglycerin composed.
- Such a preferred composition is stable at 37 ° C in the serum, but releases the content quickly when the temperature exceeds 40 ° C.
- Another preferred composition with improved release of the substances enclosed in the liposome consists of about 15 to 70% by weight of dipalmitoyl lecithin, about 10 to 25% by weight of distearoyl lecithin and more than 15 to about 45% by weight of dipalmitoylphosphoglyceroglycerin.
- the above-mentioned preferred composition of the liposome according to the invention can be tailored for other temperature ranges by choosing components with the most suitable main transition temperature.
- Table 1 shows the main transition temperatures (T M ) of phosphatidylcholines, the main transition temperatures of which are in the range from 0 to 80 ° C. The main transition temperatures can be seen from the table, depending on the chain length and the distribution over positions 1 and 2 of glycero-3-phosphocholine or over positions 1 and 3 of glycero-2-phosphocholine.
- the values listed in Table 1 show that by using fatty acids with an odd chain length and suitable distribution over the basic glycerol structure, practically any desired temperature in the specified range from 0 to 80 ° C. can be set.
- the phosphatidyl oligoglycerol content in the liposome according to the invention is essential for the long circulation time required in the serum.
- Phosphatidyl oligoglycerols and their preparation are known from DE 1 96 22 224. Dipalmitoylphosphoglyceroglycerin (DPPG2) is preferably used.
- thermolabile liposomes according to the invention are outstandingly suitable for use in various fields, but especially in the context of regional deep hyperthermia.
- Regional deep hyperthermia which is used in combination with systemic chemotherapy at specialized clinical centers, is an ideal technique for tumor-specific liposomal transport and the subsequent release of a drug from the liposomal envelope.
- hyperthermia promotes the extravasation of liposomes from tumor capillaries into the interstitium (Gaber et al., 1 996).
- warming can induce a release of the drug from special thermosensitive liposomes (Magin and Niesman, 1 984).
- thermolability of the liposomes according to the invention is caused by the phase change of the phospholipids within the liposome membrane. If the phase transition temperature is passed through, there is a brief membrane instability and subsequent release of the liposomal content.
- the tumor is regionally overheated, so that the temperature is above the limit temperature
- the liposome content here is, in particular, active ingredients which can be used in oncology, such as, for example Cytostatics.
- contrast agents such as gadolinium, for example Magnevist ® can MultiHance ® or Omniscan ®, carboxyfluorescein, iodine-containing contrast agents, which are derived sfch of pyridines or aromatic carboxylic acids, or the like. released alone or together with an active ingredient.
- the temperature-dependent release of gadolinium from the liposomes can be visualized by means of an altered T1 time using an MRI (0.2 or 1.5 Teslar).
- a non-invasive thermometry is made possible, in which the temperature reached can be determined by MRC, which measures the released gadolinium.
- MRC which measures the released gadolinium.
- a hyperthermia device coupled with an MRC device is expediently used. It is also conceivable to use liposomes with an iodine-containing contrast medium for imaging in computer tomography (for example for the thermoablation of liver metastases).
- liposomes according to the invention can be found in ophthalmology.
- a fluorescent labeling substance e.g. in the case of laser treatment by releasing the fluorescent active substance, e.g. Carboxyfluorescein, prove where the desired overheating actually occurred.
- liposomes according to the invention can therefore generally be used to make it possible to subsequently determine the temperatures reached, e.g. when certain heating temperatures or the like. should be determined.
- the liposomes according to the invention essentially consist of the substances specified above, which are preferably in pure form.
- Impurities should be kept as low as possible, in particular the cholesterol content should be as low as possible.
- Liposomes that are completely free of cholesterol since cholesterol leads to smearing of the phase transition temperature and thus to a too wide thermal transition range.
- thermolabile liposomes according to the invention are prepared in a conventional manner by dissolving the lipids, e.g. in chloroform or chloroform / water / isopropanol, stripping off the solvent, advantageously in vacuo in a rotary evaporator, annealing the lipids with aqueous solutions of the ingredients to be encapsulated at temperatures which are above the phase transition temperature.
- the duration of this tempering treatment is expediently 30 to 60 minutes, but it can also be shorter or longer. Homogenization takes place by repeated freeze-thawing processes, for example 2 to 5 times freezing and thawing again.
- lipid suspension obtained is extruded through a membrane of defined pore size at a temperature above the phase transition temperature in order to achieve the desired liposome size.
- Suitable membranes are, for example, polycarbonate membranes with a defined pore size, such as 100 to 200 nm.
- non-encapsulated contents may be used, such as column chromatography, column chromatography or the like.
- Figure 1 shows the values obtained for the in vitro CF release from thermolabile liposomes.
- Liposome composition :
- Figure 2 shows how the release temperature of DDPG 2 / DSPC / DPPC liposomes is influenced by varying the proportion of DSPC at the expense of DPPC.
- Figure 3 shows the improvement in CF release from DPDG 2 / DSPC / DPPC liposomes by increasing the proportion of DPPG 2 at the expense of DPPC (constant proportion of DSPC at 20%).
- Figure 4 shows the photon correlation spectroscopy (PCS) of liposomes from 30% by weight DPPG 2 , 20% by weight DSPC and 50% by weight DPPC (average size: 175 nm).
- PCS photon correlation spectroscopy
- Example 1 a The liposomes listed in Table 2 are prepared in the manner described above.
- Chamber model The chamber model of the Syrian hamster (A-Mel-3 melanoma of the Syrian hamster) is suitable for intravital microscopic detection of caroxyfluorescein (CF) release from thermolabile liposomes in the hyperthermia field.
- a transparent, dorsal skin chamber is implanted in a Syrian golden hamster. After the skin chamber has been implanted, cells of the hamster's A-Mel-3 melanoma are implanted on the subcutaneous tissue in the chamber.
- a tumor of several millimeters in size grows within the hamster's dorsal skin.
- the microcirculation as well as the fluorescence accumulation within the tumor can be observed with a modified vital microscope.
- the animals also receive a central venous catheter. With the help of a heat exchanger located under the skin chamber, the tumor can be locally heated to 42 ° C. The tumor temperature can be measured directly using a temperature probe (Endrich, 1 988).
