Abstract

PURPOSE:Codein, which has antitussive action, is obtained from codeinone in ingh yield, using immobilized cells of a Papaver plant. CONSTITUTION:Immobilized plant cells which are obtained by immobilizing cells of a Papaver plant in a gel of calcium alginate are cultured in a medium prepared, preferably by adding a plant growth regulator such as kinnetin to the Murashige and Skoog culture medium. Then, codeinone is added to the resultant culture medium to effect conversion into codein, which is separated and collected.

Attempts have been made to do similar things by utilizing the metabolic abilities of higher plant cells and cell cultures. A “catalyst” is a substance that has been immobilized.
It has been proposed to use it to produce or convert natural products. Specific disclosures include the hydroxylation of digitoxin to digoxin using immobilized Kegitalinos cells, the production of ajmaricin and serpentin using immobilized Catharanthus periwinkle cells, and the synthesis of anthraquinones using immobilized A7 Eyama Aoki cells. be. In order for immobilized plant cells to be used as such biorea lids, it is necessary that the special metabolic functions of the plant cells are not lost even after immobilization, and that metabolic products are not released into the medium. It is necessary that the fixed plant cells can be recovered from the culture medium and used repeatedly.

The present inventor has developed a method to produce codin by converting codinone using immobilized plant cells, which is extremely useful due to its well-known antitussive effect but could not be obtained other than by extracting it from medicinal plants. As a result of experiments, we found that this can be achieved with a high yield.
I would like to propose it here.

The method for producing codin using immobilized plant cells of the present invention includes immobilized plant cells obtained by immobilizing poppy plant cells,
The method consists of administering codinone to convert it into codin in a culture solution, and separating and collecting the produced codin. A poppy plant that can be used for this purpose is Papaver

Immobilized Zubegi cells are cultured in an appropriate medium such as agar medium to form a callus, then transferred to a liquid medium and continued to be cultured.
Actively growing cells are useful, but callus or even fresh cells themselves can be used. Protoplasts can also be used.゛ The part of the plant used for immobilization is arbitrary, but when using callus, the flower system or sprout is particularly suitable, and when using fresh cells, the capsule is particularly suitable.

For example, as in the example described later, small cells suspended in an aqueous solution of about 3% sodium alginate are dropped into a strong electrolyte solution such as calcium chloride, and the gel is solidified. For example, if the diameter is 3II
This may be carried out by forming granules of III. The cells thus encapsulated in the gel are further grown in culture for a period of time to provide immobilized plant cells for the bioreactor. The culture solution is Muraslli
(Je and S k001) Kineti in the medium
Systems with added plant growth regulators such as n. Of course, culture solutions of other strains can also be used.

Once the activity of the immobilized plant cells has been increased in this manner, codeinone is administered into the medium to cause the conversion reaction to codin. The dose is 0.00% in concentration in the medium.
0.01 to 10%, especially 0.02 to 5% is suitable. If the amount is too small, the reception will be low, and if it is too large, it will be 10
You will not be able to expect a conversion close to 0%.

In the case of batch type, the appropriate time is within one week, especially 1 to 3 days, under the above concentration and drying conditions.

After extraction, there is 11tlf? get i. This is the morphinan alkaloid fraction,
From this, codin is recovered and purified using methods such as recrystallization.

Codeinone initially administered to freshly immobilized poppy plant cells appears to be almost 100% converted to codine (there is almost no unreacted codeinone remaining in the medium unless administered at high concentrations), but some Since it is taken up into the cells, it is not possible to obtain all of it, but if it is used repeatedly and reaches a steady state, the amount released into the medium will increase, so it is not possible to secure a yield of 60%. It's easy.

The conversion rate after one week of reaction is estimated to be approximately 100%, but since the codin contained in the medium was approximately 2 ma, the yield was 40%. The remainder is considered to have been incorporated into the fixed cells.
