一般に結晶性有機化合物は、3次元空間に周期的に配列された多数の原子よりなる。構造周期性は、通例、ほとんどの分光学的プローブ(例えば、X線回折、赤外スペクトル、ラマンスペクトル及び固体NMR)によって明確に区別可能な物理的特性を発現する。中でも粉末X線回折(XRPD)は、固体の結晶性を測定するための最も感度の良い分析法のうちの1つである。X線が結晶に照射されると、結晶格子面で反射し、互いに干渉しあい、ブラッグ則よって予測される条件を満たす方向の回折線のみ強度が増大し、構造の周期に対応した秩序だった回折線を示す。一方、非晶質固体については広範囲の秩序だった回折線は認められない。非晶質固体は、通常、その構造の中に秩序だった繰返し周期をもたないため、回折現象は起こらず特徴のないブロードなXRPDパターンを示す。

式(I)で示される化合物の二塩酸塩結晶の粉末X線回析を行った結果、ブロードなピークを示したことから、式(I)で示される化合物の二塩酸塩結晶は結晶性が低いことが判明した。
一般的に、結晶性が低い結晶は、物理的安定性が低い、化学的安定性が低い等の特徴が知られており、原薬のハンドリングが難しいと言われている(参考文献:難水溶性薬物の物性評価と製剤設計の新展開、2010年、215~216ページ)。例えば、結晶性の低い結晶を原薬として使用する場合、製造のスケールアップを行った際に、結晶性の良好な結晶に転移することがあり、一定の品質の原薬を提供することが難しい。また、安定性が低いため、長期保存には向かない。
式(I)で示される化合物の一塩酸塩の各種結晶は、結晶性の良好な結晶であり、式(I)で示される化合物を一塩酸塩とすることで、医薬品の原薬に適した結晶を得ることができた。
以上より、式(I)で示される化合物の一塩酸塩の結晶は、いずれの結晶形においても結晶性が良好であり、医薬品の原薬として使用するのに好適な結晶形であることが判明した。
1.検量線の作成
式(I)で示される化合物の一塩酸塩I型結晶5 mgを精密に量り取り、アセトニトリル:水混液(1:1)に溶解させ、500μg/mLの溶液を得た。得られた溶液をそれぞれ、化合物の濃度が5 、50μg/mLになるようにアセトニトリル:水混液(1:1)で希釈し、調製し、標準の検量線を作成した。一塩酸塩II型結晶、一塩酸塩V型結晶、一塩酸塩VI型結晶、一p-トルエンスルホン酸塩I型結晶および遊離塩基結晶についても、同様の操作を行った。
2.試料溶液の作成
式(I)で示される化合物の一塩酸塩I型結晶1mgを精密に量り取り、4mL容のバイアル瓶に移した。水(注射用水)1mLを添加し、37℃で1時間攪拌した。攪拌後、この懸濁液を濾過し、濾液をアセトニトリル:水混液(1:1)で2倍に希釈した溶液を試料として、ピーク面積を測定した。濃度は、ピーク面積及び先に作成した検量線を用いて算出した。一塩酸塩II型結晶、一塩酸塩V型結晶、一塩酸塩VI型結晶、一p-トルエンスルホン酸塩I型結晶および遊離塩基結晶についても、同様の操作を行った。
(結果)
注射用水に対する式(I)で示される化合物の一塩酸塩I型結晶、一塩酸塩II型結晶、一塩酸塩V型結晶、一塩酸塩VI型結晶、一p-トルエンスルホン酸塩I型結晶および遊離塩基結晶の各溶解度を表3に示す。
(N.D.:Not Detected、単位:μg/mL)
上記表から明らかな通り、式(I)で示される化合物の遊離塩基結晶は、注射用水に対して全く溶解しないのに対し、式(I)で示される化合物の一塩酸塩I型結晶、一塩酸塩II型結晶、一塩酸塩V型結晶、一塩酸塩VI型結晶および一p-トルエンスルホン酸塩I型結晶は、注射用水に対する高い溶解度を示した。
一般的に、薬剤の溶解度は体内動態に深く関与しており、原薬は高い溶解度を有することが望まれる。従って、式(I)で示される化合物の一塩酸塩I型結晶、一塩酸塩II型結晶、一塩酸塩V型結晶、一塩酸塩VI型結晶および一p-トルエンスルホン酸塩I型結晶は、高い溶解度を有し、医薬品の原薬として使用するのに好適な結晶形であることが判明した。
式(I)で示される化合物の一塩酸塩I型結晶、一塩酸塩V型結晶、および遊離塩基結晶を、それぞれ2-プロパノール、アセトン、酢酸エチルに懸濁させて22℃下で4時間撹拌し、上澄み液の濃度を測定した。
(結果)2-プロパノール、アセトンおよび酢酸エチルに対するに溶解度を表4に示す。
表4から明らかな通り、式(I)で示される化合物の遊離塩基結晶は、各種有機溶媒に対する濃度(重量%)が高く(約0.5重量%~約8重量%)、高い溶解度を示しているのに対し、式(I)で示される化合物の一塩酸塩I型結晶および一塩酸塩V型結晶は、各種有機溶媒にほとんど溶解していないことがわかる(いずれも0.1重量%以下)。つまり、式(I)で示される化合物を製造する際、生成した化合物(I)の有機溶媒に対する溶解度が高いと、生成物が有機溶媒から析出する割合が低くなり、収量が減少することになる。従って、式(I)で示される化合物の一塩酸塩I型結晶または一塩酸塩V型結晶は、医薬品の原薬として使用するのに好適な結晶形であることが判明した。
式(I)で示される化合物の酢酸エチル溶液を調製し、当該溶液から、式(I)で示される化合物の遊離塩基結晶、一塩酸塩I型結晶および一塩酸塩VI型結晶をそれぞれ晶析した場合の、不純物除去効果を比較した。
(工程1)式(I)で示される化合物の酢酸エチル溶液の製造
化合物4(30.04g、67.4mmol)をN-メチルピロリドン(70.86g)、テトラヒドロフラン(18.68g)に溶解し、化合物(IIA)(36.85g、77.3mmol)、p-トルエンスルホン酸一水和物(15.37g、80.8mmol)、テトラヒドロフラン(53.41g)、水(5.40g)のスラリー液に加え、57℃で5時間撹拌した。室温に冷却後、化合物4(0.25g)を加えた。その後、水酸化ナトリウム水溶液でpH9.0に調整し、酢酸エチル(651.52g)で抽出した。抽出液を107.39gまで濃縮し、酢酸エチル(162.40g)を加えることで、式(I)で示される化合物の酢酸エチル溶液(269.76g)を得た。
(工程2-1)式(I)で示される化合物の遊離塩基結晶の製造
式(I)で示される化合物の酢酸エチル溶液(89.92g)を22.97gまで濃縮し、ヘプタン(17.67g)、酢酸エチル(13.27g)を加えたのち、60℃に加温すると固体が析出した。酢酸エチル(12.31g)を加えて室温に冷却し、ヘプタン(41.26g)、酢酸エチル(6.0g)を加えて49.70gまで濃縮した。ヘプタン(49.83g)、酢酸エチル(27.0g)を加えて一晩静置したのちに濾過することで、式(I)で示される化合物の遊離塩基結晶(10.91g、86.7%)を得た。
(工程2-2)式(I)で示される化合物の一塩酸塩I型結晶の製造
式(I)で示される化合物の酢酸エチル溶液(40.72g)に水(0.13g)、2-プロパノール(16.26g)を加え45℃に加温した。I型結晶の種晶(225.7mg)を加えたのちに35%塩酸でpH4.07に調整した。25℃で約30分撹拌した後に濾過することで、式(I)で示される化合物の一塩酸塩I型結晶(5.50g、90.6%)を得た。
(工程2-3)式(I)で示される化合物の一塩酸塩VI型結晶の製造
式(I)で示される化合物の酢酸エチル溶液(45.20g)に2-プロパノール(7.85g)を加え60℃に加温した。35%塩酸でpH3.5に調整後、25℃で約30分撹拌し濾過することで、式(I)で示される化合物の一塩酸塩VI型結晶(5.84g、86.7%)を得た。
上記製造法により得られた式(I)で示される化合物の遊離塩基結晶、一塩酸塩I型結晶および一塩酸塩VI型結晶について、HPLCを用いて品質を評価した。
(N.D.:Not Detected、単位:面積%)
上記で得られた各結晶の純度を比較すると、表5より明らかな通り、一塩酸塩VI型結晶、一塩酸塩I型結晶、遊離塩基結晶の順で、式(I)で示される化合物のピーク面積%の割合が大きく(順に、約%99.2、約98.4%、約97.8%)、含有される各種不純物の量が少量であることがわかる。従って、不純物が多く含まれる晶析前の溶液(酢酸エチル溶液)から晶析を行う際は、遊離塩基結晶として結晶を得るより、一塩酸塩VI型結晶または一塩酸塩I型結晶として結晶を得る方が、各種不純物を除去することができ、より高純度の結晶が得られることがわかった。
一般的に、不純物が多く含まれる結晶は、再結晶の工程を繰り返し、結晶の純度を上げる必要がある。また、再結晶工程を繰り返すと、母液に溶出する結晶の量が増え、収量が減少することになる。不純物によっては再結晶工程により除去される割合が小さいため、実用的な繰り返し回数では純度を上げることができない場合も多い。
従って、式(I)で示される化合物の一塩酸塩VI型結晶および一塩酸塩I型結晶は、一度の晶析で高純度の結晶が得られることから、大量合成に好適な結晶形であると言える。つまり、式(I)で示される化合物の一塩酸塩VI型結晶および一塩酸塩I型結晶は、医薬品の原薬として使用するのに好適な結晶形であることが判明した。
式(I)で示される化合物の一塩酸塩I型結晶、一塩酸塩V型結晶、一塩酸塩VI型結晶、遊離塩基結晶、一p-トルエンスルホン酸塩結晶および一硫酸塩結晶の水分増加質量比率を表6に示す。
一般的に、結晶を塩にすることでより吸湿の影響を受けやすくなることが考えられ、塩の種類により、吸収性は異なるといわれている(参考文献:難水溶性薬物の物性評価と製剤設計の新展開、2010年、117~118ページ)。また、水分が吸着しやすい結晶は潮解等の現象がみられ、結晶の取り扱いが困難である。さらに、そのような結晶は長期保存には適しておらず、原薬として選択されることはほとんどない。従って、式(I)で示される化合物の一塩酸塩I型結晶、一塩酸塩II型結晶、一塩酸塩V型結晶、一塩酸塩VI型結晶および一p-トルエンスルホン酸塩I型結晶は、水分増加比率が少ないことから、医薬品の原薬として使用するのに好適な結晶形であることが判明した。
式(I)で示される化合物の一塩酸塩I型結晶、一塩酸塩II型結晶、一塩酸塩V型結晶、一塩酸塩VI型結晶および一p-トルエンスルホン酸塩I型結晶の曝光試験結果を表7に示す。
(単位は面積%。*その他のピークについて曝光による変化はほとんど認められない。)
表7に示す通り、式(I)で示される化合物の一塩酸塩I型結晶、一塩酸塩II型結晶、一塩酸塩V型結晶および一塩酸塩VI型結晶を曝光試験に付すと、Z異性体からE異性体への変換がほとんど見られないか、または多くても約3.8%ほどしか増加しない。それに対し、式(I)で示される化合物の一p-トルエンスルホン酸塩I型結晶は、曝光後にE異性体が約33%増加していることから、光安定性が低いことがわかった。
一般的に、光安定性が低い結晶は、光によって分解等の現象が見られ、曝光によって許容できない変化が起きる場合がある。また、そのような結晶は、保存方法に細心の注意を払う必要があり、結晶の取り扱いが困難である。
従って、式(I)で示される化合物の一塩酸塩I型結晶、一塩酸塩II型結晶、一塩酸塩V型結晶および一塩酸塩VI型結晶は、曝光条件下において光安定性が良く、医薬品の原薬として使用するのに好適な結晶形であることが判明した。
式(I)で示される化合物の光の影響を調べるために、一定量の光を照射した後、類縁体量を測定した。
a.光照射実験法

b.類縁物質測定法
以下の方法、条件によって、液体クロマトグラフで、類縁物質を測定した。主要な類縁物質は、式(I)で示される化合物の光学異性体のE体化合物であった。従って、類縁体量の分析において、式(I)で示される化合物の光学異性体のE体化合物を分析のリファレンスとして用いた。

・サンプルクーラー温度:約5°ンプ・オートインジェクター洗浄液:アセトニトリル/メタノール混液 (1:1)
・面積測定範囲:試料溶液注入後65分間

ΣAT:試料溶液のピーク面積の合計 (ブランク及びシステムピークは除く)
ΣATi:試料溶液の個々の類縁物質のピーク面積の合計
c.結果
光の波長の変化による、類縁物質量の推移を図1に示す。その結果、光の波長が450nmよりも低ければ、波長が低くなるに応じて、総類縁体量は増加した。しかし、光の波長が450nmよりも高ければ、波長が高くなっても、総類縁体物質の量は、ほとんど増加しなかった。

また、製剤比較例1、製剤実施例1~4の錠剤に対し、光照射後の錠剤の色差を表13に示す。その結果、被覆層を設けていない製剤比較例1は、光照射後の色差が明らかに高く、人の目によっても製剤の色が変わったことは明らかであった。一方、光安定化物質および高分子を含有する被覆層を設けた製剤実施例1~4は、色差の変動は小さく、色差はΔ20以下であった。さらに、被覆層の量が多いほど、概ね色差の変動は低減した。従って、素錠の表面に、光安定化物質および高分子を含有する被覆層を設けるによって、式(I)で示される化合物を含有する製剤の色差を低減できることが明らかとなった。
