Description

Phenyl-substituted thieno [2,3-d ] pyrimidine-2, 4(1H,3H) -diones and their use
Technical Field
The invention belongs to the technical field of medicines, and relates to a compound and a pharmaceutical composition for preventing or treating sex hormone-dependent diseases, and a using method and application thereof. In particular, the invention relates to phenyl substituted thieno [2,3-d ] pyrimidine-2, 4(1H,3H) -diones which can be used as gonadotropin-releasing hormone receptor antagonists and uses thereof.
Background
The secretion of anterior pituitary hormone is feedback-controlled by peripheral hormones secreted from the target organs of the respective hormones and by secretion-regulating hormones from the hypothalamus, which is the upper central organ of the anterior pituitary (hereinafter, these hormones are collectively referred to as "hypothalamic hormones" in the specification). Currently, it has been confirmed that as hypothalamic hormones, there are nine hormones including, for example, thyrotropin-releasing hormone (TRH) and gonadotropin-releasing hormone (GnRH, sometimes referred to as LH-RH (luteinizing hormone-releasing hormone)). These hypothalamic hormones are thought to exhibit their effects via receptors that are thought to be present in the anterior pituitary; and efforts have been made to find receptor-gene expression specific for these hormones, including in humans. Thus, antagonists or agonists that specifically and selectively act on these receptors should control the action of hypothalamic hormones and the secretion of anterior pituitary hormones. Therefore, such antagonists or agonists are expected to be useful for the prevention or treatment of anterior pituitary hormone-dependent diseases.
The compounds having GnRH antagonistic activity known so far are mostly peptide compounds, for example, GnRH-derived linear peptides (linear peptides) (US 5,140,009 and US 5,171,835), bicyclic peptide derivatives (Journal of Medicinal Chemistry, Vol.36, pp.3265-3273(1993)), decapeptide compounds modified at position 5 or 6 (WO 9846634A 1) and decapeptide compounds modified at position 8 (EP 0277829B 1), and the like.
Peptide compounds present a number of problems to be solved, which are associated with oral absorbability, dosage form, dose volume, drug stability, sustained action, metabolic stability, and the like. Therefore, there is a strong need for an oral GnRH antagonist, particularly an antagonist based on a non-peptide compound, which has an excellent therapeutic effect on sex hormone-dependent diseases such as prostate cancer, endometriosis, precocious puberty and the like, which exhibits not only an instant pituitary-gonadotropic action (acute action) but also excellent oral absorbability.
Disclosure of Invention
The following is a summary of some aspects of the invention only and is not intended to be limiting. These aspects and others are described more fully below. All references in this specification are incorporated herein by reference in their entirety. When the disclosure of the present specification differs from the cited documents, the disclosure of the present specification controls.
The present invention relates to a novel class of phenyl-substituted thieno [2,3-d ] pyrimidine-2, 4(1H,3H) -diones, which have unexpectedly superior GnRH antagonistic activity and can be used as gonadotropin-releasing hormone receptor antagonists, and thus can be used for the prevention or treatment of sex hormone-dependent diseases, including, but not limited to, prostate cancer, endometriosis, uterine fibroids, precocious puberty, and the like.
The compound has stable property and good safety, and has the advantages of pharmacodynamics and pharmacokinetics, such as good brain/plasma ratio (brain plasma ratio), good bioavailability or good metabolic stability and the like, so the compound has good clinical application prospect.
The invention also provides processes for the preparation of such compounds and pharmaceutical compositions containing them.

The present invention is in no way limited to the methods and materials described herein. In the event that one or more of the incorporated documents, patents, and similar materials differ or contradict this application (including but not limited to defined terminology, application of terminology, described techniques, and the like), this application controls.
It will be further appreciated that certain features of the invention, which are, for clarity, described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the invention which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable subcombination.
The following definitions, as used herein, should be applied unless otherwise indicated. For the purposes of the present invention, the chemical elements are in accordance with the CAS version of the periodic Table of the elements, and the handbook of chemistry and Physics, 75 th edition, 1994. In addition, general principles of Organic Chemistry can be referred to as described in "Organic Chemistry", Thomas Sorrell, University Science Books, Sausaltito: 1999, and "March's Advanced Organic Chemistry" by Michael B.Smith and Jerry March, John Wiley & Sons, New York:2007, the entire contents of which are incorporated herein by reference.
The articles "a," "an," and "the" as used herein are intended to include "at least one" or "one or more" unless otherwise indicated or clearly contradicted by context. Thus, as used herein, the articles refer to one or to more than one (i.e., to at least one) of the objects. For example, "a component" refers to one or more components, i.e., there may be more than one component contemplated for use or use in embodiments of the described embodiments.
The term "patient" as used herein refers to humans (including adults and children) or other animals. In some embodiments, "patient" refers to a human.
The term "stereoisomers" refers to compounds having the same chemical structure, but differing in the arrangement of atoms or groups in space. Stereoisomers include enantiomers, diastereomers, conformers (rotamers), geometric (cis/trans) isomers, atropisomers, and the like.
The term "tautomer" or "tautomeric form" refers to structural isomers having different energies that can interconvert by a low energy barrier (low energy barrier). If tautomerism is possible (e.g., in solution), then the chemical equilibrium of the tautomer can be reached. For example, proton tautomers (also known as proton transfer tautomers) include interconversions by proton migration, such as keto-enol isomerization and imine-enamine isomerization.
"pharmaceutically acceptable" refers to those compounds, materials, compositions, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of patients without excessive toxicity, irritation, allergic response, or other problem or complication commensurate with a reasonable benefit/risk ratio, and which are effective for their intended use.
The term "optionally substituted with … …", is used interchangeably with the term "unsubstituted or substituted with ….," i.e., the structure is unsubstituted or substituted with one or more substituents described herein, including but not limited to D, F, Cl, Br, I, N3，-CN，-NO2，-NH2，-OH，-SH，-COOH，-C(＝O)NH2，-C(＝O)NHCH3，-C(＝O)N(CH3)2-C (═ O) -alkyl, -C (═ O) -alkoxy, -NHS (═ O)2-alkyl, -N (alkyl) S (═ O)2-alkyl, -S (═ O)2Alkyl, alkoxy, alkylthio, alkylamino, alkenyl, alkynyl, haloalkyl, haloalkoxy, hydroxy-substituted alkyl, cycloalkyl, heterocyclyl, aryl, heteroaryl, cycloalkyl-alkylene, heterocyclyl-alkylene, aryl-alkylene, heteroaryl-alkylene and the like.
In the description of the parts, the invention discloses the taking of compoundsSubstituents are disclosed in terms of group type or range. It is specifically intended that the invention includes each and every independent subcombination of the various members of these groups and ranges. For example, the term "C1-C6Alkyl "means in particular independently disclosed methyl, ethyl, C3Alkyl radical, C4Alkyl radical, C5Alkyl and C6An alkyl group.
In each of the parts of the invention, linking substituents are described. Where the structure clearly requires a linking group, the markush variables listed for that group are understood to be linking groups. For example, if the structure requires a linking group and the markush group definition for the variable recites "alkyl" or "aryl," it is understood that the "alkyl" or "aryl" represents an attached alkylene group or arylene group, respectively.
The terms "halogen" and "halo" are used interchangeably herein to refer to fluorine (F), chlorine (Cl), bromine (Br), or iodine (I).
