Abstract
The invention discloses atorvastatin semi-strontium salt polymorphs as well as preparation and application thereof as HMG-CoA an enzyme inhibitor. The invention discloses polymorphs HA, HB and HC or solvates of atorvastatin semi-strontium salt, which are shown as a formula (I). When used as HMG-CoA enzyme inhibitor medicines, the polymorphs HA, HB or HC, or the solvates of atorvastatin semi-strontium salt in the formula (I) are better choices for hypercalcemia syndrome, since the selected polymorphs HA, HB or HC, or the solvates of atorvastatin semi-strontium salt shown as the formula (I) notonly can achieve the purpose of controlling blood cholesterol, but also can avoid the extra intake of calcium.
Description
Technical field
The invention discloses atorvastatin semi strontium salt polymorphic form, its preparation method and as the application of HMG-CoA enzyme inhibitors.
Background of invention
The mechanism of action that statins reduces low-density lipoprotein in the body is clear and definite.The HMG-CoA enzyme can make HMG change into first hydroxyl penta salt, and this is the deciding step of biosynthesizing cholesterol in the liver.Extremely low low-density lipoprotein (VLDL) can be transferred to the cholesterol in the liver and tri-glyceride in the outside cell.VLDL is decomposed release fat acid by outside cell.VLDL will be converted into the lipoprotein (IDL) of intermediate density so, and IDL can be shifted or be transformed into LDL by low-density lipoprotein (LDL) acceptor.The content of reducing cholesterol can increase number and the corresponding amount that reduces the LDL that is changed by IDL of ldl receptor.By suppressing the HMG-CoA enzyme, statins can effectively be blocked cholesterol synthesizing in liver, thereby effectively reduces low-density lipoprotein.High LDL level can cause coronary heart disease, causes thrombus.Therefore, reduce low-density lipoprotein and can effectively prevent cardiovascular diseases, especially coronary heart disease or other hypercholesteremia syndromes.
Zarator (Atorvastatin, i.e. compound shown in the formula II) is most popular kind in the statins.The earliest, the lactone of Zarator and its calcium salt forms in the patent (US-4681893, US-5273995) of the U.S., have been mentioned.The atorvastatin semi-calcium salt trihydrate is by Pfizer called after Lipitor (LIPITOR), and 2007 annual sales amounts are above 12,000,000,000 dollars.
The patent No. is: 2002/0099224; 5273995; 5298627; 5003080; 5097045; 5124482; 5149837 United States Patent (USP) discloses the preparation process of Zarator.Half calcium salt of Zarator is seen patent US-5273995.The I of atorvastatin semi-calcium salt is disclosed in the United States Patent (USP) (US-5959156, US-6121462), II, III, IV crystal formation.The V crystal formation of atorvastatin semi-calcium salt is announced in patent WO-01/36384.Other crystal formation of atorvastatin semi-calcium salt is at patent WO-02/43732, and WO-02/41834 announces among the WO-03/070702.
Single molecule can form various salt or crystal type, such as Zarator I type or its salt (II) type, because neighboring molecule intermolecular interaction and direction is different in the crystal, different salt or the polymorphic of same molecule can have different physical propertiess.An important physical properties of medicine is its solvability, especially can dissolve in gastric juice.The drug effect of medicine is relevant with the drug level that medicine can reach in blood, and same a part, the solubility property in gastric juice and intestinal juice directly affect medicine by the absorption of GI system.Thereby the salt or the crystal formation that have the medicine of proper solubility energy may have better result for the treatment of than slower salt or the crystal formation of dissolving.The atorvastatin semi-calcium salt trihydrate is water-soluble lower, and its oral administration biaavailability only is 12%.The highly water-soluble salt of research and development Zarator can improve the oral administration biaavailability of Zarator.Thereby salt or polymorphic form that the research and development Zarator is new are very valuable.
Usually, the salt that the metal ion that organic acid and nucleidic mass are large forms water-soluble lower than low atomic weight metal cation salt of the same clan is lower than the acetylsalicylic acid calcium salt such as acetylsalicylic acid barium salt water-soluble.Yet when our salt at the screening Zarator, what be surprised to find polymorphic HA, the HB of atorvastatin semi strontium salt and HC water-solublely is higher than commercially available atorvastatin semi-calcium salt trihydrate widely.
Summary of the invention
Correspondingly, the invention discloses the polymorphic form HA of compound shown in the formula I, HB, HC or its solvate, the water-soluble of the polymorphic form HA of compound shown in the formula I disclosed by the invention or its solvate is 0.706mg/ml, the water-soluble of the polymorphic form HB of compound shown in the formula I or its solvate is 0.38mg/ml, the water-soluble of the polymorphic form HC of compound shown in the formula I or its solvate is 0.43mg/ml, under same testing method, the water-soluble of atorvastatin semi-calcium salt trihydrate only is 0.198mg/ml.Therefore, polymorphic form HA, the HB of compound shown in the formula I disclosed by the invention, HC or its solvate are all much higher than atorvastatin semi-calcium salt trihydrate.
