The present invention is based on the general formula (In the formula, R 1 represents hydrogen or an alkyl group, R 2 represents an alkyl group, and n represents an integer of 1 to 6. Here, alkyl is methyl, ethyl, propyl, isopropyl, butyl, sec-butyl, tertiary butyl,
Pentyl, octyl, etc. The present invention relates to an immunological disease therapeutic agent containing as an active ingredient an organic germanium compound (hereinafter abbreviated as the compound of the present invention) obtained by dehydration condensation polymerization of a trihydroxide compound represented by: Since the compound of the present invention promotes leukocyte migration and antibody production performance, and enhances the overall protective function,
As shown by the preventive effect of adjuvant arthritis, it is useful against collagen diseases including rheumatic diseases, as well as against various diseases accompanied by abnormalities in immune function such as infectious diseases and cancer. Kidney and liver diseases are thought to be caused by abnormal immune reactions as autoimmune diseases, and immunosuppressants and steroids are currently being used. Therefore, it is expected that the compounds of the present invention will act on the immune response system and improve kidney and liver diseases. The compound of the present invention has the general formula (In the formula, R 2 has the same meaning as above.) A compound represented by the general formula R 1 OOC-(CH 2 ) o -COCl (In the formula, R 1 and n have the same meaning as above.) It is produced by reacting with the indicated compound. (Refer to Japanese Patent Application No. 55-2461 (Japanese Patent Publication No. 63-4549)) The degree of polymerization of the compound of the present invention is 50 or less, as judged from the results of molecular weight measurement by light scattering method.
By appropriately adjusting the treatment conditions, a desired degree of polymerization can be obtained. Regardless of the degree of polymerization, they exhibit almost the same or similar pharmacological effects, but from the viewpoint of advantages in purification and formulation methods,
The degree of polymerization is preferably 10 or less. Furthermore, when the compound of the present invention is dissolved in dilute ethanol and the degree of polymerization is measured by a gel filtration method, compounds of 6 or less are detected in most cases. The magnitude and degree of dehydration condensation of the target product vary depending on the type of solvent used during treatment, temperature and time, and temperature and time during drying. Therefore, the melting point is not clear because in many cases foaming occurs due to dehydration and evaporation of crystallization water, adhering water, or remaining hydroxyl groups, resulting in a semi-molten state. Examples of the compounds of the present invention include the following compounds.
