1374742 (1) 九、發明說明 【發明所屬之技術領域】 本發明係關於藉由使治療癌症用醫藥成爲高分子膠粒 複合物,可選擇性的集聚於腫瘤部位等之病變部位(以下 稱爲腫瘤部位)’更可延長在腫瘤部位的滯留時間,而可 減少給藥次數,此外,可藉此增大抗腫瘤效果,減輕對於 正常器官組織的副作用之高分子型治療癌症用醫藥及其改 良製造方法。更詳細而言,係關於金屬原卟啉(以下稱爲 MePP )與苯乙烯·馬來酸共聚物(以下稱爲SMA )結合 ,進行配位使其變成大於腎排泄的分子大小的高分子膠粒 複合物之膠粒複合物,將其作爲有效成份之高分子型治療 癌症用醫藥,及使上述金屬原卟啉與SMA直接以特定的 pH條件在縮合劑不存在下採用特定的立體配置之高分子 型治療癌症用醫藥的製造方法。 【先前技術】 一般而言制癌劑等之藥劑既使藉由經口給藥,或注射 等進行給藥,其效果對於症灶並無特異性,因此既使爲強 效藥劑,不僅無法充分發揮效果,對於症灶以外的器官· 組織亦產生作用,而引起嚴重的副作用。這樣的強效藥劑 因爲其副作用,而給藥量的增加受到限制,此爲所謂的藥 物傳輸系統(DDS)之病灶指向型的藥劑開發在現今的世 界中競爭地硏究開發依然持續的理由。DDS硏究在副作用 影響大的制癌劑領域中特別重要。 -4 - (2) 1374742 本發明者著重於藉由抗腫瘤劑的高分子化,使其成爲 病灶指向型及緩釋放型製劑,首先發現40Kda以上的高分 子型藥劑係選擇性的集聚在腫瘤組織,更長時間滯留之獨 特現象,將此命名爲 EPR ( enhanced permeabi 1 ity and retention)效果(非專利文獻1),通透性增強及停滯效 應)效果(非專利文獻1 ),此現象係於高分子型藥劑及 脂質微粒等觀察到。 φ 發明者等基於此見解,迄今製造使藥劑與各種高分子 反應後可得到的多數的高分子型藥劑,此等高分子化藥劑 因爲上述EPR效果而被賦予高的腫瘤集聚性及對於發炎部 位的集聚性,與低分子量的抗腫瘤劑比較的結果,發現其 成爲不僅抗腫瘤效果更加優異,對於正常器官的副作用少 之優異的高分子型抗腫瘤劑(專利文獻1、專利文獻2、 專利文獻3、非專利文獻2 )。 此等高分子型抗腫瘤劑中,亦發現專利文獻3所記載 # 之低分子抗腫瘤劑與苯乙烯•馬來酸共聚物(SMA )藉由 非共價鍵結合,而形成高分子膠粒複合物結構之高分子型 抗腫瘤劑(以下稱爲SMA膠粒複合物),係抗腫瘤效果 特別優異’而且對於正常器官之副作用少之優異的抗腫瘤 劑。 【專利文獻1】日本特開平11-60499 【專利文獻2】日本特開2003 -73 2 73 【專利文獻3】W02004/10349 A1 【非專利文獻 1】Cancer Res.,44,2115-2121,1984; -5- (3) 1374742 ibid, 46, 63 87-92, 1 986; Anticancer Res., 1 3, 1 2 8 7- 1 292, 1993 【非專利文獻 2】J. Controll. Release, 74,47-61, 200 1; Adv. Enzyme Regul., 4 1, 1 89-207, 200 1 【非專利文獻 3】Cancer Res.,63,3567-3574,2003; 【非專利文獻 4】Bioconj. Chem· 13,1031-1038,2002; 另一方面,本發明者等先於上述專利文獻2中,提案 • 可使對於在發炎部位及腫瘤部位所衍生的hemoxygenase ( HO-1)爲阻礙劑之具有hemoxygenase阻礙活性的金屬口卜 啉衍生物,例如式(1 )所示之鋅-原卟啉(以下稱爲 ZnPP ),與聚乙二醇(pEG )鍵結而成爲高分子型抗腫瘤 劑。
ZnPP原本不溶於水,到目前爲止爲了使其可溶於水 中,本發明者等鍵給兩性的聚乙二醇(PEG)的平均分子 量100〜20,000 (較佳爲5,000左右),製造出可溶於水之 • 衍生物(專利文獻2 ),此PEG-ZnPP鍵結物係顯示出分 子量約6 8,000,所以此高分子在活體內的動向,在表現上 述所提的EPR效果上很重要。 【發明內容】 〔發明所欲解決之課題〕 但是PEG係其本身的分子量巨大,但相對於鍵結於藥 劑的高分子(此時1.1萬)而言ZnPP僅爲1分子,爲了 給予一定量以上的有效成份,將被高分子化的藥劑的總有 -6- (4) 1374742 效給藥量換算爲人,過多到數g以上,這簡直是增加對症 患的給予藥物量,實際上爲了獲得人類有效血中濃度,必 須投予數g〜2 50g,很難具實用性。 此外,專利文獻2中作爲兩性或水溶性的聚合物,最 適合者爲聚乙二醇(PEG),但因爲藉由直接鍵結將PEG 加成於ZnPP之方法很難,故不得不採用介著聯胺結構加 成PEG.之方法。專利文獻2係亦提及PEG以外使用SMA φ 作爲高分子化合物,但並未具體的揭示,此外敍述使用 SMA時亦與PEG加成時同樣,藉由在導入胺基之卟啉上 使SMA脫水縮合反應,而進行高分子化反應。 此外,上述專利文獻3中揭示各種低分子抗腫瘤劑-SMA膠粒複合物之製造法,無SMA-金屬PP衍生物的記 載,但作爲SMA膠粒複合物的製造方法,係使用SMA的 半丁酯等之SMA的衍生物,在酸性條件下,於溶解性碳 化二亞胺等、脫水縮合劑的存在下使其反應,接著pH昇 • 高至8以上後調節至中性,藉由脫分離純化操作,例如交 聯葡聚糖等之凝膠色譜法、超過濾膜等,回收高分子成份 之方法。 依據此方法,不必於一般被使用的膠粒化劑及微脂體 製劑使用作爲必須構成成份之乳化劑(例如糖酯、磷酯醯 膽鹼、鞘氨醇、膽固醇等),而可製造膠粒化藥劑。 但是,此反應中,如水溶解性碳化二亞胺的高價脫水 縮合劑爲必須,此外使用此縮合劑時,完全去除縮合劑極 爲困難’期望其完全去除會伴隨著藥劑的活性降低等,亦 (6) 1374742 之更簡單且便宜的製造方法,結果找出藉由使用特定的 pH條件’直接使SM A與藥劑反應,在縮合劑不存在下反 應亦進行,可得到效率佳、高純度的藥劑。 此外依據此方法在如專利文獻2中所揭示的原卟啉加 成二胺基乙烷’變成不需要授與胺基之反應操作。 〔用以解決課題之手段〕 φ 亦即本發明係金屬卟啉衍生物與苯乙烯•馬來酸共聚 物藉由非共價鍵進行結合而成的SMA膠粒複合物及其作 爲有效成份之高分子型治療癌症用醫藥。 此外本發明係使金屬卟啉衍生物與苯乙烯•馬來酸共 聚物在縮合劑不存在下、鹼性條件下進行反應,可溶化後 調節pH爲6〜8’藉由高分子成份分離操作(去除低分子 分層區分)回收高分子藥劑膠粒複合物成份之上述SMA 膠粒複合物的製造方法。 〔發明效果〕 本發明的SMA膠粒複合物係使金屬卟啉衍生物與 SMA藉由非共價鍵結合之膠粒複合物,與上述的非專利文 獻2差異極大,分子量增大至13萬附近或16萬以上,因 此對於腫瘤部位,可更選擇性的集聚,又在腫瘤內的滯留 時間亦長,因此作爲抗腫瘤效果優異,而且對於正常器官 的副作用少等之制癌性藥劑,其可用性爲更高者。 又依據本發明的SM A膠粒複合物的製造方法,不使 -9- (7) 1374742 用縮合劑而可由金屬卟啉衍生物與SMA用單純方法合成 ,而且純化步驟簡單而可得到純度高的製品。 〔實施發明的最佳型態〕 金屬卟啉衍生物係在具有卟啉環的化合物上配位金屬 之錯化合物,作爲具有卟啉環之化合物之原卟啉容易取得 ,適合使用。 # 被配位的金屬,只要是除了如汞之有毒的金屬、如1 價金屬之配位困難的金屬以外者皆可,並沒有特別的限制 ,但依用途而有所不同。作爲抗腫瘤劑使用時,不具有 hemoxygenase阻礙活性之鐵並不適合,可使用辞、錫、鈷 、鎳、銅等,但特別以鋅特別佳,原卟啉上配位鋅之Ζη-原卟啉(ΖηΡΡ )係下述式(1 )所示。 【化1】
ch3 h3c 此外,配位鐵之亞鐵原卟啉類並不適合作爲抗腫瘤劑 ,但可作爲放射線治療時的放射線增感劑使用,將其製成 -10- (8) 1374742 SMA膠粒後事先給藥,則集聚在腫瘤局部,因此可進行選 擇性的放射線治療,或可使用於自由基分子(R,R〇〇,R )等之生成的觸媒機能爲必須之情況。作爲亞鐵原卟咐類 可使用卟啉的鐵錯合物之亞鐵原卟啉、及3價的鐵卟啉配 位氯離子之氯化亞鐵原卩卜咐(hamin chloride)等,作爲 放射線增感劑可使用ZnPP等,亦可使用作爲上述抗腫瘤 劑使用之各種金屬PP。 # 本發明中作爲高分子化劑使用之SMA,係藉由苯乙烧 與馬來酸酐共聚合而得到,係具有下述式(2)或式(3) 所示之重覆單元之共聚物,具有苯乙烯與馬來酸酐作爲必 須成份》

⑶ η 但是,R爲Η或其他的烴、胺基酸、醇類。 本發明中,SMA係可直接使用苯乙烯•馬來酸酐共聚 物之無水物,但亦可使用專利文獻3所揭示的經完全開環 的苯乙烯·馬來酸(或其半烷曄物)。直接使用酸酐者不 需要水解等之操作,由可簡便地實施之觀點而言爲佳,另 • 一方面使用經開環的苯乙烯•馬來酸之方法,既使未極度 的昇高至高ρΗ( 12以上),亦可在短時間結束膠粒形成 ,具有可防止因爲強鹼性而使藥劑成份分解等之優點。 SMΑ係因爲聚合度而存在各種分子量者,本發明中作 爲高分子化劑使用的SMA,係由三聚物(約660Da )具有 約40KDa大小者較適合,更嚴密而言分子量800〜2500由 不會集聚於體內、容易排泄出體外而言爲佳。
藉由使Me PP與SMA反應之高分子膠粒複合物的製造 ,係以ZnPP爲例,係將SMA (酸酐或水解物等)與ZnPP -12- (10) 1374742 混合,加入如碳酸蘇打之鹼性液後使其成鹼性,攪拌加溫 ,加入適當的碳酸蘇打使其維持於鹼性,整體可溶化後以 酸中和,藉此產物沈澱,有效率的進行使藥劑被包含於膠 粒中,更將pH値調節於中性而可溶化後,使用超過濾、 柱色譜法等之高分子成份的分離純化操作而回收高分子成 份。經由上述的操作,藉由與SM A的立體結構變化的分 子間作用,進行使低分子藥劑包含於SMA膠粒,因此產 • 生膠粒結構。
MePP與SMA的反應係使MePP及/或SMA酸酐溶解 於有機溶劑後反應亦可,對於水爲不溶性的化合物係可使 其溶解於四氫呋喃、二甲基亞楓等之有機溶劑後反應。作 爲 SMA的溶劑,可使用丙酮、四氫呋喃、二甲基甲醯胺 、二甲基亞硒、甲基溶纖劑、乙腈、乙醇、丙三醇等,丙 酮、乙腈等特別佳,有機溶劑溶液的濃度以1〜3 0 %爲佳, 此時可添加吡啶、二胺基乙烷等作爲觸媒。 # 一邊照射超音波一邊進行MePP與SMA之反應亦可, 藉由照射超音波,可於更短時間、更效率佳的形成膠粒, 照射條件例如1分鐘〇n、1分鐘off持續5分鐘〜60分鐘 ,至少持續5~ 10分鐘。 高分子成份分離操作,係藉由分子量3,000〜50,〇〇〇的 超過濾膜進行爲佳,較佳係截斷(cut off)分子量爲3萬 ~5萬者。依據本方法所產生的SMA-ZnPP係分子量爲4萬 以上,更佳係外觀的中心分子量爲13萬〜18萬者。 如此之本發明的高分子型治療癌症用醫藥,係爲了形 -13- (11.) 1374742 成膠粒複合物,不需要界面活性劑等之輔助成份的存在, 此外亦未使用脫水縮合劑,僅使用原料之MePP與SMA而 製造,可簡單的調製僅由SMA與MePP所成的穩定的膠粒 複合物結構的藥劑。 再者,必要時可在作爲穩定化劑之乳糖、甘露蜜醇、 胺基酸、丙三醇、卵磷脂等與藥劑等量至100倍量存在下 調製此膠粒。 • 本發明的高分子型膠粒複合物治療‘癌症用醫藥係藉由 MePP與SMA之反應,形成高分子膠粒複合物結構,使 MePP包覆於膠粒內而被含有者,MePP與SMA之鍵結狀 態係氫鍵結、疏水鍵結、或離子鍵結,不存在醯胺鍵結、 酯鍵結等之共價鍵者》此可經由後述實施例所得到的圖1 的紅外吸收光譜證明。 如此作法所製造的膠粒型SMA-MePP複合物,係如同 目前爲止於高分子藥劑中所能見到的,與原本的低分子量 # 藥劑比較,可賦予有用的藥理學的性質這一點不用多說, 而且與專利文獻3的方法所製造之物比較,亦具有如下述 作爲藥劑之的優異性質。 相對於依據先前技術的方法之SMA〜藥劑膠粒複合物 的分子大小爲4萬以下者,此次依據本發明所得到的SMA 膠粒複合物的分子大小爲10萬以上約13~18萬之大幅度 的高分子化者,因爲此爲超過腎排泄界限之分子量4萬, 故大幅提高血中濃度、血中滯留性,藉此表現出更佳的 EPR效果,對於改善作爲腫瘤選擇性的藥劑之各種制癌劑 -14- (12) 1374742 有極大的貢獻。 此外,膠粒內的藥物含量係與一般的微脂體( w/wl 0〜2 0% )比較下大幅的增加(w/w40~60%),而且使 用作爲脫水縮合劑之碳化二亜胺等時,因爲將其去除極爲 困難,既使純化5次亦被確認出其殘留氮,本發明因爲不 混合入縮合劑、觸媒成份等,故可期待來自其之副作用減 少的效果。 φ 接著,此物藉由靜脈給藥因爲EPR效果而更集聚於腫 瘤組織,藉由具有ZnPP (或其他的金屬PP)之放射線增 感作用,既使照射同一線量的電磁線(7線、X線、紫外 線、α線),亦僅使含有此ZnPP的組織,接受更多的阻 礙,可逹到抗腫瘤效果更提高一層之癌症治療。亦即本發 明的高分子型治療癌症用醫藥不僅本身作爲抗腫瘤劑使用 ,亦可作爲光增感劑使用。 【實施方式】 [實施例1] (SMA-ZnPP膠粒複合物的製造方法) 平均分子量約1,500的苯乙烯與馬來酸酐共聚物( SMA) 1.5g中,加入 200ml的 0· 1M NaOH,使其成爲 pH 13,用磁力攪拌器攪拌,攪拌下加入微粉末化之鋅(Zn )-原卟啉(PP)的粉末1.5g,接著持續攪拌。隨著時間 的經過混濁液亦依序於數小時內變成深紅酒色的透明溶液 ,用離心( 3,0 00rpm)去除不溶性的ZnPP、其他的殘渣 -15- (13) (13)1374742 ,接著降至PH7附近,加入lOmM Na2C03/NaHC03溶液 約3倍量後持續攪拌此溶液,接著2小時後加入適量的 O.IM HC1,使pH約成爲7,再持續攪拌2小時,接著使 用超過濾膜的分子界限大小(分子量3,000阿米控公司製 )於加壓下濃縮至50ml爲止,藉此去除游離的ZnPP或非 膠粒化SMA或其衍生物及其分解物,而且對於含有此被 濃縮的SMA-ZnPP膠粒之分層,加入約20倍量的純水稀 釋,與上述同樣的使用超過濾膜(分子量5 0 0 0 )於加壓下 濃縮.洗淨。ZnPP的SMA膠粒物係未由此膜漏出,而僅 各游離的低分子成份漏出,可藉此進行膠粒的洗淨。最後 3次以上使用蒸餾水進行,冷凍乾燥同樣的操作總計重覆 3〜5次者,成爲注射用原物的粉末。 圖2表示SMA-ZnPP使用交聯葡聚糖G-150之分子量 的解析結果,藉此其分子量被推定爲13萬〜15萬,與IgG (免疫球蛋白、16萬)同等。 得知本發明的SMA-ZnPP膠粒係於SMA與ZnPP之間 未具有共價鍵,而是以非共價鍵的結合物。爲了證明這一 點而表示出與PEG-ZnPP對比之紅外吸收光譜。圖丨—B係 PEG-ZnPP的紅外吸收光譜,其中具有因共價鍵而產生的 典型的醯胺I、II的吸收,另一方面,圖1·Α係依據本發 明的方法之SMA-ZnPP之光譜,其中圖i_b中未有表示顯 示出醯胺鍵結樣式等新鍵結的吸收光譜。 此純化物係未通過分子量10萬的超膜,比較均句的 分佈’但其紫外‘可見光吸收光譜,與PEG-ZnPP、未修 -16- (14)1374742 飾的ZnPP —起表示於圖3,與PEG-ZnPP (圖3B)、未 修飾的ZnPP (圖3C )比較,則得知本發明的 SMA-ZnPP 膠粒複合物(圖3A)係吸收極大移動至短波長,3 50nm 附近具有小的吸收波肩。 (治療效果) 此外使用實施例1所得到的SMA-ZnPP膠粒複合物, 對於兔子的VX-2腫瘤之治療效果列示於表3。 [表 1]____ 對於兔子的VX-2腫瘤之SMA-ZnPP 的抗腫瘤效果 投與量 %生存率 鐘 40日 60日 80曰 對照組 生理食鹽 0% 0% 0% 固體腫瘤有成長、轉移 SMA-ZnPP 投與 4mg/kg 100% 60% 60% 腫瘤細胞封閉、纖維化 8mg/kg 100% 80% 80% 腫瘤細胞壞死、纖維化 12mg/kg 100% 100% 100% 腫瘤細胞壞死、完全纖維化 腫瘤移植部位:肝臟皮膜下 像這樣本發明的SMA-ZnPP膠粒複合物顯示出強力的 抗腫瘤效果,其效價優於PEG-MePP» (藉由雷射閃光分解之光增感效果) 通常的細胞培養條件下藉由對於Jurkat細胞之閃光分 解法,與PEG-ZnPP比較下評估SMA-ZnPP的光增感劑效 -17- (15) 1374742 果,雷射光照射開始後的時間(微秒)與相對吸收發光度 之關係表示於圖4,相對吸收發光度係表示ZnPP的三重 態(激起狀態)的壽命者,比較壽命(相對吸收發光度的 半衰期),相對於 SMA-ZnPP爲 2.4ps,PEG-ZnPP爲 27μδ,得知SMA-ZnPP的光增感效果係朝向効率佳且高速 前進,產生一重態氧。 圖4的結果,係Jurkat細胞中於一般的空氣環境下之 φ 結果,但於水中的結果,亦一倂進行藉由氮氣沸騰放出溶 存空氣(氧氣)之脫氧下之試驗,其結果列示於表2, SMA-ZnPP比起空氣中在Jurkat細胞中顯現出特別的顯著 效果,此外低氧環境則不怎麼有效果,抗腫瘤效果推論其 爲基於經由光照射之一重態氧生成者。 (SMA-ZnPP及PEG-ZnPP的光照射下的細胞毒性) 將淋巴球Jurkat細胞係於Du丨becco MEM培養基,於 φ 加入5%C02之空氣中,以37°C進行培養’將經由光照射 第24小時的Jurkat細胞的生存率,藉由MTT法以分光學 進行定量,結果列示於圖5’本發明的SMA-ZnPP膠粒複 合物於5.ΟμΜ的濃度,Jurkat細胞幾乎完全滅亡,而得知 優於投予同濃度的PEG-ZnPP時。 -18- (16) 1374742 [表2] 綱 "[μ5](-般狀態) τ坏哗](4〇分鐘Ν2閃光脫氧後) PEG-ZnPP 在 H20 2.5(±0.2)呷 406(±40)μ$ PEG-ZnPP 在 JCS 27(±3)μδ 325(±30)με SMA-ZnPP 在 H20 1.4(±0.2)μ$ 484(±11)哗 SMA-ZnPP 在 JCS 2.4(±0.2)叫 92(±40)μδ 1.2ms(±0.1) [實施例2] (SMA-氯化亞鐵原卟啉膠粒的製造) 於 200ml的燒杯中,加入 SMA的完全鹼水解物 300mg,加入50ml的脫離子水,用磁力攪拌器攪拌下溶解 ,接著滴定0.1M NaOH,使pH爲10。在20ml的玻璃管 形瓶中將氯化亞鐵原卩卜咐(sigma公司製)100mg溶解於 4ml的DMSO (二甲基亞碾),於上述的燒杯中於攪拌下 Φ 滴定此溶液、混合,接著滴定lMNaOH,使pH爲12,攪 拌15分鐘,接著持續滴定1M HC1,將pH降至2爲止後 變成暗褐色的懸浮液,但直接持續溶解攪拌30分鐘〜6 0分 鐘。接著藉由離心( 300 0~6000rpm)去除沈澱物與上清液 ,再加入30ml的0.02M乙酸溶液,再度攪拌(30分鐘) 懸浮液,接著於此 SMA-膠粒的水懸浮液中滴定 0.1M NaOH,將pH提高至10,30分鐘的攪拌後,再度使用 0.1M HC1使pH降至7.4,完全變成暗褐色的透明溶液, 以上的操作在室溫下進行。將其用阿米控的分子量10KD a -19- (17) (17)
