The present invention relates to anthracenedione derivatives represented by the following general formula and salts thereof. However, in the formula, R 1 and R 2 are hydrogen, lower alkyl, acyl, lower alkoxycarbonyl, lower alkoxyphenyl, or a monosaccharide such as glucose, galactose, rhamnose, 2-aminoglucose, 3-aminoglucose, or their acylated R3 means hydrogen, acyl or lower alkoxycarbonyl,
R 4 means hydrogen, acyl or trityl, m
and n is an integer from 1 to 5. Examples of the salt include salts with mineral acids such as hydrochloric acid, sulfuric acid, and bromic acid, and salts with organic acids such as citric acid. These compounds have antitumor activity and are expected to be used as pharmaceuticals, and some are useful as intermediates for the synthesis of compounds that have these uses. The method for producing the compound of the present invention is described below using the synthetic route for m-n-2, lower alkyl is methyl (Me), acyl is acetyl (Ac), and lower alkoxycarbonyl is tert-butyloxycarbonyl (Boc). Show and explain. Note that Tr means trityl. That is, Cheng's method (J.
Compound (2) was obtained by reacting 2-(2-aminoethylamino)ethanol with Med.Chem.22(5)501 (1979)).
is prepared and reacted with di-tert-butyl carbonate to produce butyloxycarbonylated compound (3). When this product is treated with an 80% aqueous acetic acid solution, the Boc group is selectively removed and compound (4) is obtained. This is treated with triphenylmethane chloride in pyridine to give a ditritylated product (5), which is then treated with 4 to 6 times the mole of dimethyl sulfate for a relatively short time (5 to 10 hours) to produce compound (6). Compound (7) is obtained by treating this with hydrochloric acid-methanol to remove the trityl group and Boc group, and by treating this with pyridine-acetic anhydride, the tetraacetyl compound (8) and the pentaacetyl compound (8) are obtained.
A mixture of (9) is obtained. These are separated and obtained by conventional methods such as chromatography. Alternatively, compound (5) is reacted with p-methoxybenzyl chloride in the presence of potassium carbonate to yield compound (10), and then reacted with dimethyl sulfate to yield compound (11). Compound (12) is obtained by treating this with hydrochloric acid and methanol, and pentaacetyl compound (13) is produced by treating this with pyridine and acetic anhydride. On the other hand, when compound (5) is treated with dimethyl sulfate at 10 times the mole or more for a relatively long time (15 to 20 hours), 1,2
-dimethoxy compound (14) is produced, and when this is treated with hydrochloric acid-methanol, the trityl group and Boc group are eliminated, resulting in compound (15). This stuff is pyridine-
It can be converted to the tetraacetyl form (16) by treatment with acetic anhydride. In addition, when compound (3) is treated with triphenylmethane chloride, compound (17) is obtained, and when this is treated with potassium carbonate and dimethyl sulfate in acetone, Boc
After migration from the 2-position to the 1-position, the hydroxyl group at the 2-position is methylated to form a 1-tert-butyloxycarbonyloxy-2-methoxy compound, and when this is treated with hydrochloric acid-methanol, the same compound ( 7) can be obtained. Compound (17) can also be led to compound (5) by heating and reacting with potassium carbonate. Compounds in which R 1 and/or R 2 are monosaccharides can be produced as shown in the following example reaction formula (wherein R 6 and R 7 are one hydrogen and the other trifluoroacetyl group) However, the exact structure is unknown). That is, when compound (17) is treated with trifluoroacetic acid, a monotrifluoroacetylated compound (18) of compound (5) is produced, and when this is reacted with acetobromo glucose, compound (19) and compound (20) are produced.
A mixture of these is produced, and these can be separated and obtained by chromatography or the like. Compound (19) or compound (20) is treated with trifluoroacetic acid, ammonia-methanol treatment, etc. to remove the protecting group to obtain compound (21) or compound (23), respectively, and these are treated with acetic anhydride in pyridine, etc. The respective acetylated forms (22) or (24) can be obtained by the following method. Examples will be described below with reference to experimental examples and examples. Thin layer chromatography is abbreviated as TLC, and the solvent system used for chromatography has a V/V composition ratio unless otherwise noted. Experimental example: Antitumor effect 1 x 10 5 L-1210 cells were transplanted into the peritoneal cavity of a CDF 1 mouse, and 24 hours later, the sample compound was injected intracytally once, and the antitumor effect was determined using physiological saline as a control. We examined the effects. The results are shown in the table below.
