1511559 Daunomycin and adriamycin derivatives SOC FARMACEUTICI ITALIA SpA 21 Sept 1976 [26 Sept 1975] 39471/75 Heading C2C Novel 4<SP>1</SP>-deoxy-daunomycins of the general formula wherein R 1 =R 3 =H and R 2 is H, methyl, methoxy, Cl or Br; R 1 = R 2 = H and R 3 is C 1-4 alkoxy; or R 2 =H and R 1 and R 3 are methyl, methoxy, Cl or Br, are prepared by condensing an aglycone of the general formula with 2,3,4,6 - tetradeoxy - 3 - trifluoroacetamido - L - threo - hexopyranosyl chloride, followed by removal of the protecting group. They may be brominated and the resulting 14 - bromo derivative hydrolysed to give the corresponding novel adriamy cin derivative. 2,3,4,6 - Tetradeoxy - 3 - trifluoroacetamido - L- threo-hexopyranosyl chloride is prepared by reacting methyl N - trifluoroacetyl - daunosaminide with methanesulphonyl chloride, treating the resulting 4-O-mesyl derivative with sodium iodide, hydrogenating catalytically the resulting 4 - desoxy - 4 - iodo derivative, hydrolysing the resulting 4-desoxy derivative with an acid, treating the resulting 2,3,4,6-tetradeoxy-3- trifluoroacetamido - L - threo - hexopyranose with p-nitrobenzoyl chloride and reacting the resulting 1-p-nitrobenzoate with HCl. 公开号:SU730310A3 申请号:SU772523451 申请日:1977-09-22 公开日:1980-04-25 发明作者:Пенко Серджо;Аркамоне Федерико;Ди Марко Аурелио 申请人:Сочиета Фармасьютичи Италиа С.П.А.

专利说明:
Hydrolysis comes with better yields and no by-products. It should be noted that the yield using the new method of converting 4-deoxidounomycin hydrochloride to 4-deoxyadriamycin hydrochloride is 50% of theoretical, while the yield by the known method is only 30%. Example 4 -deoxyadriamycin. 0.35 g of 4-deoxidaunomycin hydrochloride is dissolved in 20 ml of a mixture of anhydrous methanol and dioxane (v / v and 0.35 ml of ethyl orthoformate. 1.4 ml of a solution of 0.93 g of bromine in 10 MP of chloroform is added to this solution. 30 min at room temperature, the reaction mixture was poured into 100 ml of ethyl ether / petroleum ether (2: 1 v / v). The resulting red precipitate after filtering and washing with ethyl ether 11 1 was dissolved in a mixture of 6 ml of acetone and b ml of 0.25 n aqueous hydrobromic acid. After 12-15 hours at room temperature, the mixture is diluted with water and extracted with chloroform. The aqueous phase is extracted several times with n-bu-tanol and the combined extracts are evaporated under vacuum to a small volume to yield a 14-bromo-glucoside derivative, which is then dissolved in 6.7 ml of 0.25 n. hydrobromic acid and treated with 0.5 g of sodium phosphate in 5 ml of water. The reaction mixture is kept under stirring for 90-110 hours at room temperature and then evaporated to dryness in vacuo. The resulting residue is dissolved in 120 MP chloroform-methanol mixture (2: 1 v / v) and washed twice with 2.5% aqueous solution of NaHCOj and then re-extracted with Chloroform. The combined chloroform extract is dried over and evaporated under vacuum to low volume. With help anhydrous methanolic hydrogen chloride, the pH of the resulting red solution was adjusted to 3.5, and then an excess of ethyl ether was added to precipitate 0.17 g of 4-deoxyadriamycin as hydrochloride. T.sht. 163 ° C (with decomposition.), l +320 (with 0.05 MeOH). Chromatography in a thin layer on Kieselgur NG Merck when buffered to pH 7 with phosphate M / 15, used methylene chloride methanol - water (10: 2: 0.2 v / v) as an eluent, W 0.13. The antitumor effect of 4 -deoxyadriamycin a, established on many transplanted tumors in ml, compared with the known anti-tumor agent-adriamycin, is given in Table 1. Leukemi - L 1210. BDF mice were intraperitoneally infected with 10 leukemia cells per person and then (intraperitoneally) one day after infection with the tumor, treatment was carried out with different doses of the test compounds. .Table Adriamidine 4-Deoxyadriamycin 2/20 2/20 3/18 2/10 1/10 6/10 10/10 Female mice intravenous were infected with a suspension of lymphenods leukemia and spleen cells (2 x 10 cells of leukemia per mea) and vnu triAmitsin 4-Deoxyadriamycin The male MOP mice were intraperitoneally infected with 10 leukemia cells per mouse and a day after infection the lecteric sarcoma was injected intraperitoneally 180 Fifteen CDs, Swiss (Suiss), fragments of neoplastic tissue (solid sarcoma 180) were grown subcutaneously. And animals 1, 2, 3, 4 and 5 days later intravenously, 1.2 and 3 days after the infection, treatment was carried out for the test and connection km . The research results are summarized in table 1. table 2 183,200 3/10 216 200 1/10 233 1/9 2.75 233 different doses of the test compound. The research results are summarized in table 3. Table 3 were treated with the test compound. Tumor growth was measured 11 days after tumor implantation. The research results are summarized in table 4. T / C - the average tumor weight of the treated mouse / / average tumor weight of the control mouse X 100.
