Preparation method of 2-fluoro-5-[(4-oxo-3H-2,3-diazanaphthalene)methyl]benzoic acid

The invention discloses a preparation method of 2-fluoro-5-[(4-oxo-3H-2,3-diazanaphthalene)methyl]benzoic acid, wherein the method comprises the steps: S1, preparation of (3-oxo-1,3-dihydroisobenzofuran-1-yl)dimethyl phosphate; S2, preparation of 2-fluoro-5-(3-oxo-3H-isobenzofuran-1-yl methylene)bromobenzene; S3, preparation of 2-fluoro-5-(3-oxo-3H-isobenzofuran-1-yl methylene)methyl benzoate; and S4, preparation of 2-fluoro-5-[(4-oxo-3H-2,3-diazanaphthalene)methyl]benzoic acid. The preparation method has the advantages of simple operation, mild reaction conditions, easy purification of the intermediates, increase of the total yield compared with the prior art, and reduction of the industrial cost.

Olaparib refining method

The invention discloses an olaparib refining method, which comprises: (1) dissolving an olaparib crude product in a mixed solvent of ethyl acetate and acetone, and controlling the temperature at 45-50DEG C until olaparib is completely dissolved; (2) adding active carbon, decolorizing, filtering, cooling the filtrate to a temperature of -10-0 DEG C, crystallizing, and growing the crystal; and (3)filtering, washing the filtered solid by using acetone, and carrying out vacuum drying to obtain the refined olaparib. With the refining method of the present invention, the purity of the obtained olaparib can reach more than 99.9%, the total impurity and the single impurity are respectively controlled within 0.1% and 0.05%, the quality of the product is remarkably improved, the refining process is easy to operate, and the refining method is suitable for industrial production.

TRICYCLIC INHIBITORS OF POLY(ADP-RIBOSE)POLYMERASE

The invention provides for compositions comprising phosphorous containing tricyclic compounds, including phthalazin-l(2H)-one derivatives. The compounds are potent inhibitors of the enzyme poly(ADP-ribose)polymerase (PARP), particularly PARP-1 and potentially PARP-2. The also show good cellular activity in inhibiting poly(ADP- ribose) oligomer formation. The compounds may be useful as mono-therapy or in combination with other therapeutic agents in the treatment conditions where PARP is implicated, such as cancer, inflammatory diseases and ischemic conditions. Thus, also provided are methods for the treatment of a condition where PARP is implicated comprising administering to an effective amount of a compound of the invention to an individual in need thereof.
