Definitions
- the present invention relates to a novel fused ring pyrimidine compound or a salt thereof useful as a medicine, particularly as an antiandrogen, and a pharmaceutical composition containing them.
- Prostate cancer is the most common cancer affecting men in Europe and the United States, and the second most common cause of death in cancer.
- Japan the number of patients with prostate cancer is increasing year by year with the westernization of eating habits and the aging of the population.
- the growth of prostate cancer cells is stimulated by androgens. Therefore, in the treatment of unresectable advanced prostate cancer, it is treated by surgical or chemical castration and / or administration of an antiandrogen, so-called androgen deprivation therapy.
- Surgical or chemical castration reduces the level of androgen circulation in the body and decreases the activity of the androgen receptor (also referred to as AR).
- AR androgen receptor
- By administration of an antiandrogen agent, androgen binding to AR is inhibited, and AR activity decreases.
- Non-Patent Documents 1 and 2 As a cause of castration resistant prostate cancer, AR gene amplification and overexpression have been confirmed and reported (Non-Patent Documents 1 and 2). Due to the overexpression of AR, castration resistant prostate cancer is also highly sensitive to very low concentrations of androgens from castration treatment. That is, AR overexpression activates AR and causes tumor growth. AR mutations have also been confirmed and reported as a cause of castration resistant prostate cancer (Non-Patent Documents 3 to 5). When AR is mutated, in addition to androgen, for example, estrogen and the currently used antiandrogen agent itself act as an AR agonist.
- Bicalutamide the most commonly used antiandrogen, shows an inhibitory effect as an antagonist to AR in hormone-sensitive prostate cancer.
- antiandrogens used for androgen deprivation therapy including bicalutamide are not effective against castration resistant prostate cancer.
- the main causes are that AR is overexpressed in castration-resistant prostate cancer, and AR antagonist activity cannot be fully exerted and AR agonist activity is exhibited (Non-patent Documents 6 and 7). Therefore, in order to inhibit the overexpressed AR possessed by castration resistant prostate cancer, an antiandrogenic agent having a stronger AR antagonist activity than an existing antiandrogen agent and having no AR agonistic action is required.
- an antiandrogen agent has the effect of reducing AR expression, it can be a more effective castration resistant prostate cancer treatment (Non-patent Document 8).
- Patent Literature discloses a vanilloid receptor 1 (VR1) inhibitor.
- Patent Document 1 describes bicycloheteroarylamine compounds useful for pain, inflammatory hyperalgesia, overactive bladder and urinary incontinence by inhibiting the VR1 receptor.
- Patent Documents 2 and 3 describe bicycloheteroarylamine compounds useful for the treatment of inflammatory pain and the like, and test data for thermal hyperalgesia is disclosed.
- Patent Documents 1 to 3 do not report a compound having cyanobenzene at the 7-position of 5,6,7,8-tetrahydropyrido [3,4-d] pyrimidine.
- there is no description of data on antitumor effects and there is no description of AR antagonist activity or AR expression lowering effect.
- the object of the present invention is to have stronger antagonist activity against AR that is overexpressed in castration-resistant prostate cancer than current antiandrogens, including bicalutamide, and does not show agonistic effect on AR. And it is providing the novel condensed ring pyrimidine compound or its pharmaceutically acceptable salt which has the effect
- the inventors of the present invention have 5,6,7,8-tetrahydropyrido [3,4-d] pyrimidine as a basic structure, which is a condensed ring pyrimidine compound, and represented by —NHR 1 at the 4-position. And a novel group of compounds having cyanobenzene or nitrobenzene at the 7-position. These compound groups have antagonist activity against AR but do not exhibit agonist activity, and have a strong cytostatic effect on cells overexpressing AR in addition to the effectiveness against cells expressing AR. In addition to the antagonist activity against AR, these compound groups have an action of decreasing AR expression, and show an antitumor effect in a tumor-bearing mouse model of castration-resistant prostate cancer. Therefore, the present inventors have found that these compound groups are effective as a medicament for treating cancer, and have completed the present invention.

試験例1:ARに対するアンタゴニスト活性
ARに対するアンタゴニスト活性を以下の方法で評価した。pMMTV-lucベクター(アンドロゲンレスポンスエレメントとしてマウス乳癌ウイルス末端反復配列(Murine Mouse mammary Virus Long Terminal Repeat)をもつレポータープラスミド)とpEX-hARベクター(ヒトのアンドロゲン受容体の発現ベクター:CMVプロモーターの制御下にヒトAR遺伝子を発現する)を、トランスフェクション試薬としてNucleofector(登録商標)Kit R(Lonza)を使用し、Amaxa(Lonza)を用いてCOS-7細胞(ATCC)にトランスフェクションした。トランスフェクションしたCOS-7細胞をチャコール処理した牛胎児血清(以下、DCC-FBS)10%を含むフェノールレッドフリーRPMI1640(以下、評価培地)で1.5×104/wellとなるようにクリアボトム96wellマイクロプレート(BD)に播種し、一晩培養した。この培養物に、ジヒドロテストステロン(DHT)を含む評価培地(DHTの終濃度1nmol/L)と、実施例化合物又は比較例化合物(Bicalutamide)を含む評価培地(該実施例化合物又は比較例化合物の終濃度5、14、41、123、370、1111、3333、又は10000nmol/L)を添加し、24時間培養後、レポータープラスミドの転写活性値を測定した。転写活性は、Bright-GloTMLuciferase Assay System(Promega)で測定した。測定した転写活性から、1nmol/L DHTによる転写活性値を100%、評価培地のみの転写活性値を0%として、ロジスティック回帰により50%転写活性阻害濃度(IC50値)を算出した。
アンドロゲン受容体遺伝子が増幅しているヒト前立腺癌細胞LNCaP(非特許文献5)をDCC-FBS 5%を含むフェノールレッドフリーRPMI1640(以下、評価培地)で4.0×103/wellとなるようクリアボトム96wellマイクロプレート(BD)に播種し、一晩培養した。この培養物に、DHTを含む評価培地(DHTの終濃度1nmol/L)と、実施例化合物又は比較例化合物(Bicalutamide)を含む評価培地(該実施例又は比較例化合物の終濃度(5、14、41、123、370、1111、3333、10000又は30000nmol/L)を添加し、72時間培養後、生細胞数を測定した。生細胞数はCell Counting Kit-8(同仁化学研究所)を用いて測定した。測定した生細胞数から、1nmol/L DHTによる細胞増殖活性値を100%、評価培地のみの細胞増殖活性を0%として、ロジスティック回帰により50%増殖阻害濃度(GI50値)を算出した。
AR陽性ヒト前立腺癌細胞VCaP(In Vivo 15:163-168,2001)DCC-FBS 5%を含むフェノールレッドフリーRPMI1640(以下、評価培地)で1.5×104/wellとなるようクリアボトム96wellマイクロプレート(BD)に播種し、一晩培養した。この培養物に、実施例化合物又は比較例化合物(Bicalutamide)を含む評価培地(該実施例化合物又は比較例化合物の終濃度5、14、41、123、370、1111、3333、又は10000nmol/L)を添加し、72時間培養後、生細胞数を測定した(試験群)。対照として、評価培地のみ添加して培養し、生細胞数を測定した(対照群)。生細胞数はCellTiter-GloTM Luminescent Cell Viability Assay(Promega)で測定した。測定した生細胞数から、評価培地のみの生細胞数を基準として実施例化合物又は比較例化合物の細胞増殖率を算出した。
細胞増殖率(%)
=(試験群の生細胞数-対照群の生細胞数)/(対照群の生細胞数)×100
評価培地のみの生細胞数の誤差を考慮し、評価した8濃度における細胞増殖率がいずれかの濃度で細胞増殖率が10%を超えた場合、ARに対するアゴニスト活性有りと判断した。
AR陽性ヒト前立腺癌細胞LNCaPを、5%FBSを含むRPMI1640(以下、評価培地)で3.5×105/wellとなるよう6wellマイクロプレート(BD)に播種し、一晩培養した。この培養物に、実施例化合物又は比較例化合物(Bicalutamide)を含む評価培地を、実施例化合物又は比較例化合物の終濃度が10000nmol/Lとなるよう添加し、48時間培養した。48時間培養後に培地を除き、細胞をPBSで洗浄後、Lysis buffer (M-PERにProtease Inhibitor Cocktailを添加)0.1mLを添加して、4℃で20分間静置し、細胞を溶解後、細胞溶液を遠心分離して上清をCell Lysateとして回収した。Cell Lysateの蛋白質濃度をそろえて、SDS-PAGEを行い、抗AR抗体(サンタクルズ社、N-20)を用いてWestern Blottingを行った。Super Signal West Dura Substrate(Thermo Scientific)を検出試薬として用い、LAS Imaging System(FUJIFILM)で抗体反応バンド(抗AR受容体)を定量した。この定量において、評価培地コントロールと比べてLNCaPのAR発現が50%以上低下していた場合、AR発現低下作用ありと判断した。
AR陽性ヒト前立腺癌細胞LNCaPから論文(Clin Cancer Res,2001 7:2941-8)報告を基に、去勢耐性前立腺癌LNCaP-Xeno-IL-6細胞(当該論文ではLNCaP-IL-6+細胞と報告)を樹立し、これを用いてin vivo試験を行う。LNCaP-Xeno-IL-6細胞を雄ヌードマウス皮下に移植し、腫瘍体積がおよそ200mm3になったところで、去勢処置する。去勢後、媒体(0.5%HPMC)のみ、又は媒体に懸濁した実施例化合物を、2週間連日経口投与する。実施例化合物は曝露量を合わせて投与する。2週間投与後の腫瘍体積を記録し、媒体のみ投与群の平均腫瘍体積に対する評価化合物投与群の平均腫瘍体積を、T/C(%)として下記式に基づき算出する。
T/C(%)=(評価化合物群の平均腫瘍体積)/(媒体投与群の平均腫瘍体積)
