The present invention relates to a useful amino azole derivative as a pharmaceutical compound. More particularly, it relates to an amino azole derivative and a medically acceptable salt thereof which are useful for treatment or prevention of androgen receptor-related diseases such as sarcopenia and disuse muscle atrophy, cachexia or muscular dystrophy.
Endogenous steroidal androgen such as testosterone or 5α-dihydrotestosterone (DHT) exerts physiological and pathophysiological actions by binding to an androgen receptor (referred to as “AR”), a nuclear receptor. AR induces cell strain-specific gene expression in a target tissue. AR consists of three main functional domains including a ligand binding domain (LBD), a DNA binding domain and an amino terminal domain. A substance which binds to AR and shows an endogenous steroidal androgenic action is called AR agonist, while the one which inhibits the action of AR ligand is called AR antagonist. After AR binds to a ligand and the product is delivered into a nucleus, the product forms a complex with plural proteins such as a transcription coupling factor and a cell strain-specific coupling factor and binds to a target gene or an androgen responsive element (ARE), which is a DNA sequence (binding motif) in the region of a promoter or enhancer of genes that AR easily binds to, and thereby controls the production of protein encoded by a specific gene.
Androgen has actions such as a protein anabolic action, a gonadotropin secretion inhibitory action, and the promoting action of erythropoiesis as well as that in the reproductive system, and target cells for androgen are variously distributed into organs including external sex organs, accessory sex organs as well as brain, pituitary gland, muscle tissues, bones, and kidneys (NPL 1). The androgenic protein anabolic action includes the increase of a skeletal muscle mass and skeletal muscular strength, and the increase of bone quantity and bone density (NPL 2). Therefore, androgen is expected to be useful for prevention and/or treatment for disuse muscle atrophy occurring as a result of inactivity by sarcopenia and bedridden or immobilization resulting from plaster cast fixation, cachexia (such as cancers, heart failure, chronic obstructive pulmonary disease and end-stage renal disease and the like), furthermore, muscular dystrophy (such as Duchenne dystrophy, myotonic dystrophy and the like).
However, steroidal androgen has a poor first-pass effect in the liver, and hepatotoxicity and cross reactivity with other steroid hormone receptors such as glucocorticoid receptor (GR) have become problem (NPL 1). Therefore, a selective androgen receptor modifier (SARM) as nonsteroidal androgen, which increases a skeletal muscle mass, muscular strength, bone quantity and bone density by binding to AR, is highly promising by selective binding to AR compared to other steroid hormone receptors without danger of hepatotoxicity. Therefore, many SARMs are under development in an early development stage (NPL 3). Ostelin (brand name) has the most developed and its phase I and phase II clinical trials have been completed (NPL 4). In addition, SARM is expected to be effective for the use in the promotion of regeneration and restoration of muscles (NPL 5), in the area of hormonal male contraception and benign prostatic hypertrophy (BPH) and wound healing (NPL 6).
In PTL's 1-5, a compound is disclosed whose partial structure is coincident with the amino azole derivative of the present invention. However, the same compound is not described and there is no description about their relations to AR. A compound with the activity of AR antagonist is described in NPL 7, but its chemical structure is different from the amino azole derivative of the present invention. Further, NPL 7 does not suggest that the amino azole derivative of the present invention has an AR agonist activity.
The purpose of the present invention is to provide a novel compound having the active regulating action of AR. In addition, it is to provide a therapeutic or prophylactic agent containing a novel compound having the active regulating action of AR as an active ingredient for AR-related diseases such as sarcopenia and disuse muscle atrophy, cachexia, muscular dystrophy or the like.

Evaluation of an Androgen Receptor Affinity
To examine the interaction of a compound with an androgen receptor, evaluation was carried out in accordance with the following procedure using PolarScreen™ Androgen Receptor Competitor Assay Kit, Red (Invitrogen). To 2 wells each of a 384 well black plate was added 5 μL of the compound solution. To each well was added 5 μL of 2×AR-LBD/Fluoromone AL Red Complex contained in the kit and the samples were reacted at 22° C. for 5 hours. After 5 hours of the reaction, fluorescence polarization was measured and the affinity was evaluated. The affinity of the compound was determined by comparing to the binding rate of 1 μM of dihydrotestosterone (DHT), and quantified the logarithm value (pEC50) of reciprocal value of the effective concentration of the compound which is equal to 50% of the binding rate by applying a 4 parameter goodness-of-fit calculation. The results are shown in the Tables.
Reporter Assay of an Androgen Receptor Responsive Sequence
To examine the agonist activity of compounds for androgen, a reporter assay using an androgen receptor responsive sequence was conducted.
Using Lipofectamine 2000 (Invitrogen), a plasmid mixture (pGL4-ARE (200 ng/well), pcDNA3-hAR (20 ng/well), pRL-TK (Promega) (150 ng/well)) was transiently transfected into HEK293 cells. The contents of the plasmid (mixture) are as follows:
pGL4-ARE is a reporter plasmid containing firefly luciferase sequence under the control of androgen receptor responsive sequence; pcDNA3-hAR is a plasmid containing full-length sequence of human androgen receptor under the constant control of CMV promoter; pRL-TK is a plasmid containing Renilla Luciferase sequence under the control of herpes simplex virus thymidine kinase and used as an internal standard for evaluations of transfection efficiency and compound toxicity.
After the incubation of Lipofectamine 2000 and the plasmid mixture in Opti-MEM for 20 minutes, the mixture was mixed with a cell suspension prepared with Opti-MEM in the similar way, and the cell suspension was plated to a 96-well plate at 20000 cells/well. The transfection was conducted by incubating the plates under the condition of 5% CO2 at 37° C. for 3 hours. Three hours after the transfection, the culture medium was removed and a compound solution prepared by DMEM supplemented with 5% FBS and treated with charcoal was added, and the mixture was incubated under the condition of 5% CO2 at 37° C. for 24 hours. After the incubation with the compound, luciferase activities were measured with a luminometer using Dual-Glo™ Luciferase Assay System (Promega). The measurement of the luciferase activities was performed in accordance with the protocol recommended by Promega. The activity of the compound was determined by comparing to the activity of 100 nM of DHT, and quantified the logarithm value (pEC50) of reciprocal value of the effective concentration of the compound which is equal to 50% of the activity value by applying a 4 parameter goodness-of-fit calculation. The results are shown in the Tables.
Evaluation of Protein Anabolic Action in a Male Rat Model with Orchiectomy
Using an orchiectomy male rat model, the protein anabolic effect of compounds was screened. For male Sprague Dawley rats of 8-10 weeks of age, orchiectomy was surgically conducted under Nembutal anesthesia and kept them untreated for 14 days. After 14 days, animals were randomly assigned to test groups based on their body weights. Test compounds were subcutaneously or orally given them for 14 days. Approximately 24 hours after the last administration, animals were euthanized and the wet weight of levator ani muscle was measured.
Protein anabolic effect (% Eff.) was determined as follows:
% Eff.=((wet weight of the levator ani muscle of a test animal/body weight of a test animal)−average value of (wet weight of the levator ani muscle of a control animal/body weight of a control animal))/(average value of (wet weight of the levator ani muscle of a sham operation animal/body weight of a sham operation animal)−average value of (wet weight of levator ani muscle of a control animal/body weight of a control animal))×100. The results are shown in the Tables. In addition, the symbols (−, +, ++, +++) indicating the intensity of drug efficacy in a table represent the following % Eff.
% Eff.≥130%: +++
130%>% Eff.≥100%: ++
100%>% Eff.≥65%: +
% Eff.<65%: −
From these results, it was clear that the compound of the present invention, a medically acceptable salt thereof or a solvate thereof had an excellent protein anabolic effect.
A compound of the present invention or a medically acceptable salt or a solvate thereof are used as a pharmaceutical compound.
