Sterilized at 120 ° C. for 20 minutes. The pH after sterilization varies between 6.8 and 7.0. The inoculated flask was agitated on a rotary shaker at 28 ° C. for 2 days at 280 rpm with 7 cm eccentricity. The amount equal to 2ml of the medium, the following medium: 6% starch; 1.8% corn steep liquor; 0.1% yeast extract; 0.25% NaCl; 0.3% CaCO 3; 0.001% FeSO 4 .7H 2 O; 0.001% ZnSO were inoculated into 300ml flasks containing 100 ml 30 ml of deionized water; 4 .7H 2 O; 0.001% CuSO 4 .5H 2 O. Sterilized at 120 ° C. for 20 minutes. The flasks were incubated for 7 days at 28 ° C. with 7 cm eccentricity at 280 rpm on a rotary shaker.
Example 2
According to Example 1, broth medium (20 liters) supplemented with acetonitrile (1 liter) was filtered using celite. The filtrate was concentrated (6 liters) under vacuum and extracted with n-butanol (2 × 500 ml) at pH 8.2. To the organic phase containing compound (I) and other anthracyclines was added HCl acidic water (100 ml pH 2.5) followed by ethyl ether (2 liters) and n-hexane (2 liters). . After shaking, the aqueous phase is separated, concentrated in vacuo, made up to a small volume with n-propanol, titrated with a spectrophotometer and supplemented with 2 equivalents of methanolic HCl and excess n-hexane to give a crude red precipitate. Induced product formation. The precipitate was collected by filtration and dried in vacuo (600 mg).
When examined by TLC, it contained novel compound (I) and other glycosidated anthracyclines.
Example 3
The crude precipitate containing (I) obtained according to Example 2 was dissolved in a small volume of water: acetonitrile (9: 1) and chromatographed on a Lichroprep RP-8 column (310-25 mm). Elution was performed with a mixture of water: acetonitrile (8: 2) adjusted to pH 3 with trifluoroacetic acid. The collected fractions were analyzed by TLC and those containing a single spot were pooled and concentrated in vacuo and lyophilized.
75 mg of red lyophilized product is obtained, the properties of which are shown in Tables 4 and 5.
After addition of 0.1N aqueous acetic acid (0.2 ml), an aliquot (6 mg) dissolved in dioxane (0.5 ml) was heated to 85 ° C. for 1 hour. The reaction mixture diluted with water was extracted with chloroform at pH 8.2 and the organic phase was dried over sodium sulfate, concentrated to a small volume and titrated to make up for 1 equivalent of methanolic HCl. A precipitate formed and was collected, dried (3 mg) and analyzed by TLC and identified as daunomycin (IV) compared to the pure sample. The remaining aqueous phase contained the amino sugar vancosamine (VII), identified by direct TLC comparison with a genuine sample.
Another aliquot (6 mg) was dissolved in 0.2N HCl (2 ml) and heated to 100 ° C. for 1 hour. The red precipitate was collected by filtration, washed with water, dried (2 mg), and analyzed by TLC and identified as daunomycinone (VIII) by direct comparison with the genuine sample.
The aqueous residue analyzed by TLC contained two amino sugars identified as daunosamine (XI) and vancosamine (VII) by direct comparison with genuine samples.
The product obtained by fermentation was identified as 4'-O-vancosaminyl daunomycin (I).
Example 4
A sample of pure 4′-O-vancosaminyl daunomycin (I) obtained according to Example 2 (8 mg) was dissolved in water (0.8 ml), adjusted to pH 9 with aqueous NaHCO 3 solution, and NaBH 4 (0.6 mg) was supplemented and held at ambient temperature for 5 minutes. After adding a few drops of methanol and 0.05N HCl to pH 4.5, the solution is chromatographed on RP-8 as described in Example 3 and after lyophilization the properties are listed in Table 4. A new red product is obtained.
Aliquots subjected to mild acid hydrolysis as described in Example 3 yielded 13-dihydrodaunomycin (V) and vancosamine (VII), which were identified by direct comparison with genuine samples under TLC.
From aliquots subjected to strong acid hydrolysis as described in Example 3, 13-dihydrodaunomycinone (IX), daunosamine (XI) and vancosamine (VIII) were identified by comparison with genuine samples under TLC. It was.
The new product thus obtained by chemical transformation of (I) was identified as 4'-O-vancosaminyl 13-dihydrodaunomycin (II).
Example 5
4′-O-vancosaminyl daunomycin (I) (15 mg) was dissolved in an anhydrous methanol: dioxane 1: 3 mixture and supplemented with ethyl orthoformate (0.05 ml). After 15 minutes, the solution was cooled to 5 ° C. The, Br 2 (in 5% CHCl 3 0.15ml), supplement HCl (in methanol 0.02 ml 2.5M), it was held overnight 4 ° C..
Upon addition of 5 volumes of n-hexane, a red precipitate was obtained, which was dissolved in acetone (1 ml), 0.25 M HBr aqueous solution (1 ml) was added and left at 4 ° C. overnight.
This solution was brought to pH 4.3 with 1M aqueous NaCOOH solution, then kept magnetically stirred for 2 days at ambient temperature and then chromatographed on an RP-8 column as described in Example 3.
After lyophilization, a new red product was obtained (6 mg) whose properties are listed in Table 4.
Doxorubicin and vancosamine were each obtained from aliquots subjected to mild acid hydrolysis as described in Example 3, which were identified by direct TLC comparison with genuine samples.
From aliquots subjected to strong acid hydrolysis as described in Example 3, adriamycinone (X), vancosamine (VIII) and daunosamine (XI) were each identified by comparison with genuine samples in TLC.
The new product thus obtained by chemical transformation of (I) was identified as 4′-O-vancosaminyl doxorubicin (III).
