Abstract
一種聚合物膠束載體組成物,其包含:i)嵌段共聚物,其具有親水性聚合物鏈片段及疏水性聚合物鏈片段;ii)帶電界面活性劑;及iii)脂肪油。該載體組成物可應用作為化妝品組成物或醫藥品組成物之基材,且非親油性藥物之載持性優異。非親油性藥物可舉毛成長促進胜肽為例。
Description
本發明係有關於可應用作為化妝品組成物之載體的聚合物膠束載體組成物,及在該載體組成物上載持藥物之聚合物膠束組成物。
具有來自聚乙二醇之親水性片段及來自聚胺基酸之疏水性片段之嵌段共聚物藉由聚合物彼此之疏水性相互作用而形成在內殼部分具有疏水性區域的聚合物膠束構造。使用該嵌段共聚物之聚合物膠束技術的既有研究是利用疏水性相互作用之膠束形成機制,使如難水溶性抗癌劑之紫杉醇之類的難水溶性藥物可在未化學鍵結於嵌段共聚物之情形下全部內包於膠束內的技術(專利文獻1或2)。此外,聚合物膠束技術亦可用在作成應用了亦是難水溶性藥物且亦是美白成分之一種的β-檜酚酮的化妝品組成物(專利文獻3)。
另一方面,由依據如此疏水性相互作用之利用聚合物膠束技術的藥物內包原理來看,可認為是不容易提供
非親油性藥物之載持性優異的聚合物膠束組成物。
專利文獻1:日本專利第2777530號公報
專利文獻2:國際公開第2004/082718號公報
專利文獻3:國際公開第2008/026776號公報
本發明之一主要目的在於提供一種可大幅提高非親油性藥物之載持性的聚合物膠束載體組成物。此外,本發明之另一主要目的在於提供一種非親油性藥物之載持性優異之聚合物膠束組成物。
本發明人發現若刻意使用在原理上認為是與非親油性藥物之親和性不佳的脂肪油作為聚合物膠束組成物之一構成要素,則會有助於大幅提升膠束組成物所生之非親油性藥物的載持性,而完成本發明。
本發明提供一種聚合物膠束載體組成物,其可應用作為化妝品組成物之載體,且包含:i)嵌段共聚物,其具有親水性聚合物鏈片段及疏水性聚合物鏈片段;ii)帶電界面活性劑;及iii)脂肪油。又,從本發明之另一方面來看,提供一種聚合物膠束組成物,其具有該載體組成物及載持於該載體組成物上之非親油性藥物。
依據本發明,可提高聚合物膠束組成物中之非親油性藥物的載持性。
本發明之聚合物膠束載體組成物,除了嵌段共聚物以外,亦含有帶電界面活性劑及脂肪油。脂肪油雖然在原理上被認為與非親油性藥物之親和性不佳,但藉由刻意作為載體組成物之一構成要素,並與嵌段共聚物及帶電界面活性劑組合使用,有助於大幅提高載體組成物之非親油性藥物的載持性。
脂肪油可為選自於習知植物油、動物油及合成油之油脂成分。更具體而言,脂肪油可為由動植物採取之油(油脂)中在20℃且標準大氣壓(101.325kPa)下為液體的脂肪成分。植物油可舉例如:橄欖油、芝麻油、大豆油、山茶油、玉米油、菜籽油、蓖麻油、椰子油、花生油、棉籽油、鱷梨油、葵花油及杏仁油。動物油可舉例如:肝油、魚油、海龜油、貂油及蛋黃油。在本說明書中,氫化上述舉例之油而製得之加工脂肪油亦包含在動物油及植物油中。
在本說明書中,非親油性藥物意味在20℃且標準大氣壓(101.325kPa)下之流動石蠟中的最大溶解度為100mg/L以下,更嚴密來說,10mg/L以下的藥物。

依據本發明,可大幅提高聚合物膠束組成物中之非親油性藥物的載持性。更具體而言,如後述之實施例所示,可提供非親油性藥物之載持率到達例如20質量%以上、例如30質量%以上、例如40質量%以上、例如70質量%以上之優異聚合物膠束組成物。此外,在本說明書中,該載持率意味相對以嵌段共聚物換算100質量份之聚合物膠束載體組成物,以5質量份之比例混合及攪拌溶解於15mL之
100mM磷酸緩衝液的非親油性藥物,並在5℃靜置一晚後,使用高速液相層析儀測量水相中之非親油性藥物之游離量,並與添加於載體組成物中之藥物量對比而算出的值。
雖然藉本發明提高非親油性藥物之載持性的原因並不確定,但推測如下。首先,本發明之聚合物膠束載體組成物之構造,在原理上係呈以下狀態,即:以包圍脂肪油之方式,將嵌段共聚物以疏水性聚合物鏈片段朝向內側且親水性聚合物鏈片段朝向外側之狀態下放射狀地配置,進一步在脂肪油之周圍配置帶電界面活性劑,使其親油性部分朝向內側、親水性部分朝向外側且親油性部分靠近脂肪油。而且,本發明之聚合物膠束組成物之構造在原理上係呈保持非親油性藥物靠近帶電界面活性劑之親水性部分的狀態。因此可認為,具有帶電界面活性劑有在捕捉非親油性藥物之狀態下作為用以連接固定在脂肪油上之錨的機能,又,脂肪油透過帶電界面活性劑有作為用以將非親油性藥物保持在膠束組成物內之錨座的機能,藉此可提高膠束組成物中之非親油性藥物的載持性。因此,在本說明書中所謂「膠束組成物中之非親油性藥物的載持」,並不限於配置在由嵌段共聚物之疏水性聚合物鏈片段形成之聚合物膠束組成物內的疏水性區域的狀態,亦包含配置在該疏水性區域之外側(由親水性聚合物鏈片段形成之親水性區域)的狀態。
嵌段共聚物之親水性聚合物鏈片段可為來自聚乙二醇之片段,而疏水性聚合物鏈片段可為來自聚胺基酸
之片段。親水性聚合物鏈片段與疏水性聚合物鏈片段可藉共價鍵鍵結主鏈彼此之末端。

嵌段共聚物中之疏水性聚合物鏈片段,例如,可呈在其重複單元中具有烷基側鏈胺基酸或芳烷基側鏈胺基酸之殘基的狀態。該烷基側鏈胺基酸可舉例如:丙胺酸、纈胺酸、白胺酸及異白胺酸。該芳烷基側鏈胺基酸可舉苯基丙胺酸為例。具有2以上之烷基側鏈胺基酸及/或芳烷基側鏈胺基酸的殘基時,雖然該等殘基可為同一胺基酸殘基,但亦可混合2種以上不同之烷基側鏈胺基酸及/或芳烷基側鏈胺基酸的殘基。疏水性聚合物鏈片段之烷基側鏈胺基酸或芳烷基側鏈胺基酸之殘基對全重複單元的比率沒有限制,可為例如20%以上、例如35%以上、例如40%
以上、例如50%以上、例如80%以上、例如95%以上、例如99%以上、例如100%。
疏水性聚合物鏈片段之分子質量對親水性聚合物鏈片段之分子質量100%可設定為例如10%以上、例如20%以上,且可設定為例如400%以下、例如300%以下。
嵌段共聚物之結構式可舉以下之通式(I)及(II)為例。
在通式(I)及(II)中,R1及R3分別為氫原子、C1-6烷氧基、芳氧基、芳基C1-3氧基、氰基、羧基、胺基、C1-6烷羰基、C2-7醯胺基、三-C1-6烷氧基、矽氧烷基、矽烷胺基;R2為氫原子、飽和或不飽和之C1至C29脂肪族羰基或芳羰基;R4為氫原子、飽和或不飽和之C1至C30脂肪族氧基或芳基-低級烷氧基。

芳基側鏈。R5及R6中非碳數1至8之烷基側鏈或芳基側鏈之胺基酸側鏈可為具有OH基或COOH基之親水性基。

在通式(III)及(IV)中,R7係-O-或-NH-;R8係氫原子、苯基、苄基、-(CH2)4-苯基、未取代之或以胺基或羰基取代之C4至C16烷基、或固醇衍生物之殘基;R9係亞甲基。
在通式(III)及(IV)中,n1係在10至200之範圍內的整數;n2係在0至200之範圍內的整數(但是,n2為1以上時,(COCHNH)之單元與(COR9CHNH)之單元是隨機地存在,且n2為2以上時,R8係在1嵌段共聚物內之各胺基酸單元中分別獨立選擇且隨機地存在,但R8為氫原子時係R8全體之75%以下);y係1或2。
嵌段共聚物之結構式可舉以下之通式(V)及(VI)為其他例子。
在通式(V)及(VI)中,R1、R2、R3、R4、R5、R6、m、L1及L2之定義與通式(I)及(II)中之定義相同;R7、R8、R9、及y之定義與通式(III)及(IV)中之定義相同。
在通式(V)及(VI)中,n3係在1至200之範圍內的整數;n4係在1至200之範圍內的整數;n5係在0至200之範圍內的整數。但是,n4表示之單元及(n5為1以上時)n5表示之單元互相隨機地存在。n3表示之單元,與n4表示之單元以及(n5為1以上時)n5表示之單元,可隨機地存在,亦可分
成由n3表示之單元形成之嵌段,與由n4表示之單元以及由(n5為1以上時)n5表示之單元形成之嵌段而存在。此外,n3個重複單元中50%以上,例如80%以上、例如90%以上、例如95%以上、例如99%以上、例如100%為碳數1至8之烷基側鏈或芳基側鏈。n3個重複單元中非碳數1至8之烷基側鏈或芳基側鏈之胺基酸側鏈可為具有OH基或COOH基之親水性基。另外,對n3表示之單元、n4表示之單元及(n5為1以上時)n5表示之單元的總數n3+n4+n5,n3表示之單元的比率可為例如20%以上、例如35%以上、例如40%以上、例如50%以上、例如80%以上、例如90%以上。
嵌段共聚物,例如,可藉由將具有親水性聚合物鏈之聚合物及具有聚胺基酸鏈之聚合物以原樣、或依需要縮小分子質量分布之方式精製後,以習知之方法耦合而形成。通式(I)之嵌段共聚物,例如,亦可藉由使用可賦予R1之起始劑進行陰離子活聚合形成聚乙二醇鏈後,在成長末端側導入胺基,並由該胺末端聚合包含烷基側鏈胺基酸之所希望胺基酸而形成。
載體組成物及膠束組成物中之脂肪油對嵌段共聚物的質量比可為,例如50質量%以下、例如20質量%以下。雖然載體組成物及膠束組成物中之帶電界面活性劑對脂肪油的質量比可為100質量%以下,但膠束組成物中之帶電界面活性劑的含量宜設定為具有非親油性藥物具有之相反電荷量以上之電荷量的狀態。
載體組成物可,例如,如下所述地形成。即,
可藉由以下步驟形成:i)調製在有機溶劑中添加嵌段共聚物、帶電界面活性劑及脂肪油之形成溶液;ii)由該形成溶液去除有機溶劑;iii)將該去除後之殘存物(例如,固形物或糊)添加至水中,以調製含有嵌段共聚物、帶電界面活性劑及脂肪油之懸浮液;iv)使該懸浮液中之嵌段共聚物、帶電界面活性劑及脂肪油的混合物分散。膠束組成物可在該載體組成物之形成後形成,或就預先準備之載體組成物而言,藉由混合非親油性藥物及載體組成物而形成。非親油性藥物可在含有該藥物之藥物溶液的狀態下與載體組成物混合,亦可藉由添加在含有載體組成物之溶液(例如在上述iv)中製得之分散液)中來混合。有機溶劑可舉例如:丙酮、二氯甲烷、二甲基甲醯胺、二甲基亞碸、乙腈、四氫呋喃、甲醇。形成溶液可含有2種以上之有機溶劑,且可進一步含有少量之水。有機溶劑可藉由蒸發、萃取或膜分離之類的習知方法由形成溶液去除。添加有機溶劑去除後之殘存物的水亦可包含鹽或安定劑等之添加物。混合物之分散可使用超音波照射、高壓乳化機或擠壓機之類的習知微小化手段。
本發明之聚合物膠束載體組成物可適合作為化妝品組成物之載體,亦可適合作為醫藥品組成物之載體。而且,本發明之聚合物膠束組成物可作為化妝品組成物使用,亦可作為醫藥品組成物使用。此外,在本說明書中將醫藥部外品視為包含在化妝品內。因為本發明之聚合物膠束組成物可將特徵之性質利用於浸透至表皮內側至真皮
外側之皮膚組織內(表皮層內)且安定地留下的聚合物膠束,所以適合作為皮膚外用劑。例如,若將含有毛成長促進劑之膠束組成物給藥在皮膚上作為非親油性藥物,則膠束組成物會可滯留在毛根周邊,並在毛根附近持續地釋放毛成長促進劑。如此,本發明之聚合物膠束組成物可作為皮膚外用劑之毛成長促進劑用的化妝品組成物或醫藥品組成物來使用。此外,膠束組成物亦可作為經口給藥或非經口給藥(靜脈給藥、腹腔內給藥等)之醫藥品組成物來使用。
