Description
Technical Field
The invention relates to an amorphous form of a pharmaceutical compound, in particular to an amorphous form of 1- [3(R) - [ 4-amino-3- (4-phenoxyphenyl) -1H-pyrazolo [3, 4-d ] pyrimidin-1-yl ] piperidin-1-yl ] -2-propen-1-one, a preparation method and a pharmaceutical composition thereof.
Background

The target preparation prepared from Ibrutinib can selectively inhibit Bruton Tyrosine Kinase (BTK), and can be used for treating Chronic Lymphocytic Leukemia (CLL) and Mantle Cell Lymphoma (MCL). MCL and CLL both belong to B cell non-Hodgkin lymphoma, have difficult healing and easy recurrence, and the common chemoimmunotherapy has no targeting property and often causes serious adverse reaction. Ibrutinib can be combined with BTK targeting necessary for B lymphocyte formation, differentiation, information transmission and survival to irreversibly inhibit the activity of BTK and effectively inhibit the proliferation and survival of tumor cells; and the oral drug can be absorbed quickly, the maximum blood concentration can be achieved within 1-2 h, and adverse reactions are mild and micro, so that the oral drug becomes a new choice for treating CLL and MCL.
Ibrutinib (Ibrutinib) was first developed by Celera gene technology, usa (Celera Genomics), which is known for the mapping of "human genomes"; in 2006, Celera transferred the right to develop this drug to the United states biopharmaceutical pharmaceuticals corporation; in 2011, the grandfather son corporation of Yankee corporation (Jassen) collaborated with the pharmaceutical corporation of America until approved for marketing.
United states biopharmaceutical pharmaceuticals corporation disclosed in patent CN104736178A 3 anhydrous hydrate crystal forms (crystal form a, crystal form B, crystal form C, respectively) and 3 solvates (methyl isobutyl ketone solvate crystal form D, toluene solvate crystal form E, methanol solvate crystal form F, respectively). Wherein, the solubility of the crystal form A and the crystal form B is not high under the condition that the pH value is 7-8, and the two crystal forms are not beneficial to improving the bioavailability and the curative effect of the medicine. In addition, in alternative cases, the solvate forms (form D, form E, form F) are generally not suitable for direct use as pharmaceutical forms, relative to the anhydrate forms.
Suzhou Jingyun pharmaceutical science and technology, Inc. describes in its patent application CN104327085A (publication No.) another crystal form of 1- [3(R) - [ 4-amino-3- (4-phenoxyphenyl) -1H-pyrazolo [3, 4-d ] pyrimidin-1-yl ] piperidin-1-yl ] -2-propen-1-one and a method for its preparation.
Different crystal forms of 1- [3(R) - [ 4-amino-3- (4-phenoxyphenyl) -1H-pyrazolo [3, 4-d ] pyrimidin-1-yl ] piperidin-1-yl ] -2-propen-1-one may have differences in solubility and stability, so that the dissolution and release of the pharmaceutical composition in vitro are influenced, and the bioavailability of the pharmaceutical composition in vivo is further influenced.
