Patent Application
20230064976
The invention belongs to the field of medicinal chemistry, in particular to an amorphous form or crystalline form of a 2-Indolinolinololylspironone compound or its salt and solvent complex used as an MDM2 inhibitor and its preparation method and application.
The p53 tumor suppressor plays an important role in controlling cell cycle progression, senescence, and apoptosis (Vogelstein et al., Nature 408:307 (2000); Goberdhan, CancerCell 7:505 (2005)). MDM2 and p53 are part of an autoregulatory feedback loop (Wu et al., GenesDev. 7:1126 (1993)). MDM2 is transcriptionally activated by p53 and MDM2, which in turn represses p53 activity through at least three mechanisms (Wu et al., GenesDev. 7:1126 (1993)). First, the MDM2 protein directly binds to the p53 transactivation domain, and consequently inhibits p53-mediated transactivation; second, the MDM2 protein contains a nuclear export signal sequence, and when bound to p53, induces the nuclear export of p53, thereby preventing p53 binding to the targeted DNA; and third, the MDM2 protein is an E3 ubiquitin ligase and, when bound to p53, is able to promote p53 degradation.
WO2015/161032A1 disclosed a 2-Indolinolinololylspironone compound that inhibits MDM2-P53 interaction and therefore activates the function of p53 and p53-related proteins for therapeutic applications, which not only showed improved stability of their chemical solution, but also showed unexpectedly improved antitumor activity, including complete tumor regression in animal models of human osteosarcoma. Specifically, Compound No. 8 (referred to herein as Compound 1), described in its labeling, binds to MDM2 protein with IC50 values and Ki values of 3.8 nM and <1.0 nM, respectively. The compound blocks the interaction of MDM2 with P53 and induces periodic arrest and apoptosis in a P53 dependent manner with the structural formula:
However, the current literature including this patent application mainly reports the structure and pharmacological activity of this type of compound, and has not conducted any research and report on its polymorphism, amorphous and other forms.
Due to the influence of various factors such as the configuration, conformation, molecular arrangement, molecular force, eutectic substance, etc. of the molecular structure of a solid substance, the spatial arrangement of the molecular lattice is different, forming two or more different crystal structures, this phenomenon is called “Polymorphism Phenomenon” or “Phenomenon”. “Polymorphism” is widespread in solid drugs, and there may be differences in physical and chemical properties between different crystal forms of the same drug, such as appearance, density, hardness, melting point, solubility, stability, dissolution rate, dissolution rate, bioavailability, etc. There may be significant differences, and this phenomenon is particularly obvious in oral solid preparations. In addition, the existence and quantity of polymorphic compounds are unpredictable. Different crystalline forms of the same drug have significant differences in solubility, melting point, density, stability, etc., which affect the uniformity, bioavailability, efficacy and safety.
In addition to polymorphs, some solid compounds may also exist in amorphous forms. Amorphous refers to the structure of some imperfectly crystalline amorphous regions (amorphous regions) or the formation of some amorphous solids (non-crystalline). For a specific solid drug, its amorphous form and quantity are also unpredictable, and may also have a significant impact on the solubility, melting point, density, and stability of the drug.
Therefore, in the development of new drugs, a comprehensive screening of crystalline and amorphous forms of drug compounds is required, considering multiple factors. In particular, for the above-mentioned compound 1 used as an MDM2 inhibitor, the development of an amorphous or crystalline form of the compound or its salt or solvate that may have pharmaceutical value can improve the stability, solubility, and bioavailability of the compound. It has potential medicinal and clinical value.
The present invention provides amorphous or crystalline forms of 2-Indolinolinololylspironone compounds or their salts and solvates used as MDM2 inhibitors, as well as preparation methods and applications thereof. The amorphous form or crystalline form of the present invention has good stability and is of great value for drug development, formulation development and production.
