リウム0.1gを得た。The present invention relates to a monoalkali metal salt of a porphyrin compound represented by the formula: (R represents a lower alkyl group) and a method for producing the same. Protoporphyrin in which R 1 is represented by a vinyl group in the formula () is already a known compound and is used as a liver function treatment agent. -Alkoxyethyl-8-vinyl-deuteroporphyrin is a novel compound synthesized by the present inventor, and is a compound useful as a tumor therapeutic agent having an excellent laser photosensitizing effect. However, the porphyrin compound of the formula () and its dialkali metal salt are sparingly soluble in water, and this has been a major obstacle to formulation, especially since protoporphyrin is used as an injection. Therefore, conventionally, in order to prepare an injection solution of protoporphyrin, protoporphyrin was dissolved in an aqueous solution of caustic soda and the pH was adjusted. However, with this method, it was not possible to maintain a constant quality because protoporphyrin itself could not be obtained in a highly pure form and it was difficult to adjust the pH to a constant level. The present inventors previously succeeded in quantitatively obtaining the dialkali metal salt of protoporphyrin from highly purified protoporphyrin dimethyl ester, but the dialkali metal salt of protoporphyrin does not dissolve in water in ordinary salt. It is hardly soluble. When the dialkali metal salt is suspended in water and heated while being subjected to ultrasound, it dissolves transparently, but when it is left to cool, it becomes suspended again, making it unsuitable for use as an injection. Ta. Under these circumstances, the present inventor conducted extensive research and found that the monoalkali metal salt of the porphyrin compound of formula () is easily soluble in water and does not form a precipitate even when stored in a cool place, and that this solubility The salt is
The present invention was completed by discovering that the dialkali metal salt of the porphyrin compound can be obtained by neutralizing it with an acidic substance that is more acidic than the equivalent molar amount of the porphyrin compound. That is, in the present invention, a solution of a dialkali metal salt of a porphyrin compound represented by the formula (2) is treated by adding an acidic substance that is more acidic than the porphyrin compound in the same molar amount as the porphyrin compound, to obtain a monoalkali metal salt of a porphyrin compound. This is a method for producing a soluble salt of a porphyrin compound, characterized in that it is obtained as a porphyrin compound. To carry out the present invention, first, a dialkali metal salt of a porphyrin compound () is suspended in water, and heated to 70 to 90° C. while applying ultrasound to dissolve it. Next, an acidic substance is added to this while stirring to neutralize half of the dialkali metal salt. As the acidic substance, any substance having stronger acidity than the above-mentioned porphyrin compounds can be used, but weak acids such as weakly acidic ion exchange resins, acetic acid, and citric acid are preferable. The acidic substance is added in an equimolar amount or in slight excess with the porphyrin compound (), and the reaction is 2
It is preferable to carry out for ~5 hours. After the reaction, the reaction mixture is dried by freeze-drying or the like to obtain a soluble salt of the porphyrin compound. As shown in the Examples below, this soluble salt is a monoalkali metal salt of a porphyrin compound, and is easily soluble in water, physiological saline, etc. at room temperature or low temperature, and is extremely convenient for producing injections, for example. . Next, reference examples and examples will be given and explained. Example 1 (i) Protoporphyrin disodium (purity 99%)
10g of the above) was suspended in 3.5ml of distilled water, an ultrasonic vibrating rod was inserted into the suspension, and the mixture was heated to 80°C. The suspension became a clear solution in 30 minutes. To this solution, 5 ml of activated weakly acidic ion exchange resin (Amberlite IRC-50: Organo Co., Ltd.) was added while stirring, and the mixture was stirred for 3 hours. The ion exchange resin was separated from the reaction solution, the solution was passed through a 0.2μ membrane filter, and lyophilized to obtain 9 g of a soluble salt of protoporphyrin. (ii) 512 mg (3% moisture) of this freeze-dried product was mixed with distilled water.
Dissolve in 50ml, add 50ml of 0.1N acetic acid,
The precipitated protoporphyrin was separated. When 50 ml of this liquid was accurately taken, 3 drops of phenolphthalein reagent was added, and the mixture was back titrated with 0.1N caustic soda, 7.9 ml was consumed. Therefore, this freeze-dried product contained 3.95% sodium and was confirmed to be protoporphyrin monosodium. Example 2 (i) To an aqueous solution of protoporphyrin disodium prepared in the same manner as in (i) of Example 1, 99% was added under stirring.
% acetic acid (1.10 mol) was added and stirred for 3 hours. The following was freeze-dried in the same manner as in Example 1,
9.5 g of soluble salt of protoporphyrin was obtained. (ii) Dissolve 34 mg of this lyophilized product in 100 ml of methanol containing 10% hydrochloric acid, add 10 ml of this solution to a 25 ml volumetric flask, add 2 ml of triethylamine to neutralize it, add dichloroethane to it,
ml. When 10μ of this solution was subjected to high performance liquid chromatography, a peak was observed at the same retention time as protoporphyrin dimethyl ester, and no other peaks were observed. Example 3 10 g of 3-methoxyethyl-8-vinyl deuteroporphyrin (MVD) disodium was added to 500
ml of distilled water, 5 ml of activated weakly acidic ion exchange resin (same as in Example 1) was added thereto, and the mixture was stirred for 3 hours. Remove the ion exchange resin,
The solution was passed through a 0.2μ membrane filter and then lyophilized to obtain 9.2g of a soluble salt of 3-methoxyethyl-8-vinyl-deuteroporphyrin. When measured in the same manner as in Example 1 (ii), it was found to be a monosodium salt. Reference Example (i) 1 g of protoporphyrin dimethyl ester was suspended in 500 ml of methanol, hydrogen chloride gas was introduced into the suspension to saturate the suspension, and the suspension was boiled for 3 hours. Pour this into 10% ammonium carbonate aqueous solution 1,
Extraction was performed with 200 ml of dichloroethane, and the extract was washed with water and dried over sodium sulfate. This extract was poured onto a silica gel column that had been previously washed with dichloroethane to be adsorbed, and elution was performed with dichloroethane. The raw material protoporphyrin dimethyl ester was eluted first. (ii) The second eluting fraction (confirmed to be a single spot by TLC) was collected, the solvent was distilled off, and the residue was recrystallized from toluene.
0.13 g (13% yield) of MVD dimethyl ester was obtained. Elemental analysis value C 37 H 42 N 4 O 5 Calculated value (%): C: 71.36, H: 6.80, N:
