Description
Technical field
The present invention is the medicine N-substituted benzene benzothiazolyl-1-substituted-phenyl-O with Antiphytoviral and antitumor action, O-dialkyl-alpha-amino phosphonate ester derivatives and preparation method thereof.
Background technology
The α-An Jilinsuan ester separates in the sheep body at first and obtains, caused investigators' concern thereafter, synthetic, the bioactive research paper enormous amount of derivatives such as relevant α-An Jilinsuan ester, its biological activity also is extended to all respects of agricultural chemicals and medicine, see relevant α-An Jilinsuan ester and synthetic thereof summary document (as: Song Baoan etc., novel optical active alpha-amido phosphonate progress, organic chemistry for details, 2003,23 (9): 933; Song Baoan etc., the synthetic and bioactivity research progress of α-An Jilinsuan ester, organic chemistry, 2004,24 (8): 843.).
Yuan Cheng already waits the people to synthesize a series of α-An Jilinsuan derivative (Yuan, C.-Y. respectively at 1993,1998,2000 reports; Wang, G.-H.; Feng, H.-Z.Phosphors, Sulfur, Silicon Relt.Elem.1993,81,149.; Yuan, C.-Y.; Zhang, Y.-X.; Luo, W.-H.; Yao, Z.-P.Heteroatom Chem.1998,9,139.; Xiao, J-B, Zhang, X-M, Yuan, C-Y.Heteroatom Chem.2000,11,536.).
People such as Liu Xuejun had reported synthetic a series of 5-fluor-uracil-1-base phosphorus tripeptide compounds that contain the antitumour activity group in 2002, and had carried out Anticancer Activities.Find in the experiment, in the α-An Jilinsuan ester, the substituent volume of another of alpha-position is big more, alpha-amino nucleophilicity is more little, electron-withdrawing substituent will reduce the nucleophilicity of amido, when substituting group is that product yield is starkly lower than the yield of product under other situation when on aryl and the aryl nitro substituent being arranged, and when being nitro with the ortho position of aryl, the product that obtains expecting is failed in reaction.All target compounds are carried out external antitumour activity tentatively test, when production concentration is 1 * 10
-5During mol/L, the result shows that this compounds of part has certain anticancer (HL-60 and BEL-7404) effect.
Reports such as Song Baoan in 2002 contain synthetic and resisting tobacco mosaic virus (TMV) activity of trifluoromethyl-α-An Jilinsuan ester.Drug concentration is 5 * 10
-4G/L is 49.65～70.12% to the tobacco mosaic virus (TMV) inhibiting rate.(Song Baoan, Wu Yanglan, Huang Rongmao, CN02113256,2002.; Song, B.-A.; Wu, Y.L.; Yang, S.International Symposium on Frontiers in MolecularScience, Qingdao, 2002, p66.)
In recent years, inventor research group is in order to seek new high-efficiency anti-plant virus agent and antitumour activity new compound, the working foundation that synthesizes with original fluorine-containing amido phosphonate, introduce the benzothiazole group in the molecule, design with synthesized N-substituted benzene benzothiazolyl-1-substituted-phenyl-O, O-dialkyl-alpha-amino phosphonate ester compound, carry out have the design of anti-plant virus agent and antitumour activity heterocycle new compound, synthetic and biological screening.
