Abstract
The invention relates to the field of pharmaceutical engineering, and discloses an oxaliplatin preparation method. According to the invention, potassium chloroplatinite is adopted as a raw material, and is subjected to a reaction with trans-L-1,2-cyclohexanediamine and potassium iodide according to a molar ratio of 1:1:6.02, such that cis-diiodo(trans-L-cyclohexanediamine)platinum is produced; under a dark condition, an aqueous solution of silver nitrate is added, and a reaction is carried out for 12-18h; pump filtration is carried out, and active carbon is added into the filtrate for purifying and decolorizing; potassium oxalate is added into the filtrate, and a reaction is carried out for 4h under room temperature; and a filter cake is vacuum-dried to constant weight. A molar ratio is that Pt(DACH)I2: AgNO3: K2C2O4 = 1:2:1.2. The method has the advantages of simple process flow, high synthesis yield, and suitability for industrial productions using chemical raw material reagents.
Description
Technical field
The present invention relates to the synthetic preparation of antitumor drug oxaliplatin.
Background technology
Oxaliplatin has another name called RP-54780, and English name Oxaliplatin is abbreviated as L-OHP, and full name is that cis-oxalic acid (trans-(-)-1,2---hexanaphthene) closes platinum, and molecular weight is C
8H
14N
2O
4Pt, its structural formula is:
Oxaliplatin is the earliest by Switzerland Debiopharm company exploitation, gets permission to be mainly used in treating the transitivity cancer of colon for clinical in France in 1997, is used for clinical in a plurality of countries and address approval at present.
Volume 6 periodicals carried in 1989 the 14th " Oxaliplatin " and " synthesizing and structural characterization of RP-54780 " two pieces of disclosed oxaliplatins of document of 21 first phases phase of " precious metal " end of the year 2000 publication synthetic be that to close platinum with cis-dichloro (trans-left-handed-cyclohexanediamine) be intermediate, add Silver Nitrate, remove by filter silver-colored throw out, add sodium oxalate in the mother liquor, reaction generates the aqueous solution of oxaliplatin, and concentrating under reduced pressure obtains the oxaliplatin product.
Characteristics such as this technology exists yield low, and impurity is many.
Summary of the invention
In view of this, the invention provides the high method for preparing oxaliplatin of a kind of yield.
Step 1. potassium chloroplatinite is raw material, with trans-left-handed-1,2-cyclohexanediamine and potassiumiodide reaction generate cis-diiodo-(trans-left-handed-cyclohexanediamine) and close platinum.
Step 2. cis-diiodo-(trans-left-handed-cyclohexanediamine) closes platinum adds Silver Nitrate under the lucifuge condition reactant aqueous solution 12-18h, adds excessive activated carbon purification decolouring behind the suction filtration.
Reaction raw materials mol ratio potassium chloroplatinite in the step 1 of the present invention: trans-left-handed-1,2-cyclohexanediamine: potassiumiodide=1: 1: 6.02, adding excessive potassiumiodide can make reaction more complete, productive rate is higher, simultaneously can with step 2 in the money market ionic reaction, remove silver ions residual in the solution.
In the step 2 of the present invention the growth in reaction times can intermediate reaction more complete, improve productive rate, suction filtration can be removed the Silver iodide of precipitation, adds gac simultaneously and can remove the Silver iodide that suspend in the solution and excessive I
-Ion.Add potassium oxalate in the suction filtration rear filtrate, the reaction back suction filtration that finishes with small amount of ethanol and the washing of a small amount of frozen water, is drained final vacuum and is dried to constant weight and namely gets oxaliplatin.
