Description
根據35 U.S.C. § 119(e),本申請案主張2009年5月6日提出申請之美國臨時申請案序號61/176,057的優先權;該申請案之揭示以引用方式納入本文中。
本發明係關於皮膚遞送組成物及將該等組成物用於活性劑遞送應用之方法。
各種不同活性劑已發展且持繼發展於治療各種不同情況(包括疾病及非疾病情況二者)之用途。關於該等應用,有效量之活性劑必須遞送至需要其之對象。已發展各種不同遞送調配物及路徑,其中該等路徑可視活性劑之性質而改變。典型地,較沒有侵入性的遞送路徑為更好容忍的且因此更令人想要。
因其最小地侵入性質而極感興趣的遞送路徑之一類型為皮膚遞送。在皮膚遞送中,活性劑組成物係施用於皮膚位置以將活性劑遞送至對象。多數目前使用中或在評估下的皮膚遞送技術並不完全人滿意。例如,某些皮膚遞送技術會瓦解角質層(Sc)之完整性及/或依賴滲透增強劑的存在,滲透增強劑會引起不想要的損害及/或刺激。除此之外,某些皮膚遞送技術可為以聚合物-及/或脂質體為主的技術,該二種技術都沒有真正地遞送通過Sc。而且這些技術不能適用於大分子量生化活性物質,等等。
就這點而論,持續需要發展克服一或多種目前皮膚遞送方法所經歷的缺點之新穎皮膚遞送技術。
提供皮膚遞送組成物。該等皮膚遞送組成物之特點包括活性劑/磷酸鈣粒子複合物之存在,其中這些複合物包括與一或多種活性劑結合之均勻剛性球形奈米孔洞磷酸鈣粒子。也提供將該等組成物用於活性劑遞送應用之方法。
提供皮膚遞送組成物。該等皮膚遞送組成物之特點包括活性劑-磷酸鈣粒子複合物之存在,其中這些複合物包括與一或多種活性劑結合之均勻剛性球形奈米孔洞磷酸鈣粒子。也提供將該組成物用於活性劑遞送應用之方法。
在進一步描述本發明之前,應了解本發明並不侷限於所述特定體系中,就其本身而論可能改變。亦應明瞭本文中所使用之用語僅是為了闡述特定具體例,而非意欲作為限制,因為本發明之範圍僅係由所附申請專利範圍來限定。
當提供一數值範圍時,應明瞭介於該範圍上、下限之間的各個中介數值(除非前後文明確地另有指出,否則計算至該下限單位的十分之一),以及所述範圍內之任何其他所述數值或介於中間的數值,均涵括於本發明中。這些較小範圍的上與下限可獨立地涵括在較小範圍內並且亦涵括在本發明中,受到在所述範圍中任何被特定排除的限制。當所述範圍包括限值中之一或二者時,不含有這些被包括之限值中之一或二者的範圍亦包括於本發明中。
某些範圍以前面帶有術語“約”的數值出現在本文中。術語“約”使用於本文中以對後方之準確數值以及接近或近似該數值之數值提供文字支持。在決定一數值是否接近或近似於一特別被列舉的數值時,接近或近似的未列舉數值可為一個存在於上下文的數值,提供特定所列數值的實質等效值。
本文中所列方法可以任何邏輯上可能的所列事件之順序,以及所列事件的順序進行。
除非另有定義,所有本文中所使用的技術以及科學術語具有如熟習本發明所屬技藝之一般技藝人士通常理解的相同意義。雖然任何類似或相同於該等在本文中所述者的方法以及材料也可用於實施或測試本發明,但現將說明較佳方法以及材料。
所有在本文中引用的公開資料以引用方式納入本文中以揭示及說明與該公開資料所引用者有關的方法及/或材料。提供本文中所討論之公開資料僅僅因為它們的揭示在本申請案申請日之前。在本文中不應被解釋為憑藉先前發明而承認本發明無權先於該公開資料。再者,所提供的公開日期可能不同於實際公開日期,它們可能需要分別確認。
必須注意如使用在本文及申請專利範圍中,單數形式"一(a)"、"一(an)"及"該(the)"包括複數所指物,除非本文中另有明確指示。進一步注意申請專利範圍可草擬為排除任何隨意要件。就其本身而論,這個說明意欲作為使用此等排除性用語如“僅僅(solely)”、“僅(only)”以及與申請專利範圍要件的列舉有關的類似者,或使用“負面(negative)”限定的前置基礎。
在進一步描述本發明的各種特點中,更詳細描述根據某些體系之活性劑-磷酸鈣粒子,接著包括活性劑-磷酸鈣粒子之遞送組成物的體系之說明,以及製造及使用包括活性劑-磷酸鈣粒子之複合物及遞送組成物的方法。
如上文所概述,提供活性劑遞送組成物。本發明之活性劑遞送組成物包括存在於遞送媒液之活性劑-磷酸鈣粒子複合物。現更詳細地分開檢討遞送組成物之活性劑-磷酸鈣粒子複合物之遞送媒液成分。
存在於本發明之遞送組成物中的活性劑-磷酸鈣粒子複合物包括與一或多種活性劑結合之均勻剛性球形奈米孔洞磷酸鈣粒子。如粒子與一或多種活性劑結合時,一或多種活性劑係以方式結合於粒子。活性劑可經由許多的不同結合型式結合於粒子,包括但不限制於:離子結合、共價結合、凡得瓦相互作用、氫結合相互作用、正相及逆相分配相互作用、等等。同樣地,粒子可描述為裝載某量之一或多種活性劑。“裝載”是指粒子包括某量之一或多種結合至粒子的活性劑(換句話說某量之單一活性劑或二或多種不同活性劑)。如活性劑被結合至粒子,當粒子存在於遞送組成物時,活性劑不會以任何實質量從粒子解離。因為實質上沒有活性劑從粒子解離,任何進行解離之量為30%或更小,諸如20%或更小,例如,10%或更小,包括5%或更小,以活性劑的原結合量的重量計。結合至粒子的活性劑成分(其由一或多種不同的活性劑製造)之量可視組成活性劑結合粒子之特定活性劑而改變,及在某些體系中,範圍從0.01至1000毫克/克,諸如從0.1至750毫克/克及包括1至300毫克/克活性劑)/克粒子。
活性劑係與磷酸鈣粒子可逆地結合。“可逆地結合”是指活性劑在遞送至對象之後(例如,將包括複合物之遞送組成物施用至皮膚位置之後)從磷酸鈣粒子釋放。如下文更詳細所檢討者,複合物之磷酸鈣粒子在酸性條件下(諸如在pH 5或更小,例如,pH 4.9或更小,pH 4.7或更小,pH 4.5或更小,pH 4.3或更小之條件下)降解。當粒子降解時,它們釋放其活性劑“載重量(payload)”。角質層(SC),皮膚的最外層,係由大約20層的細胞組成且厚度大約為10微米。SC之pH視其深度而改變。其最外層從pH 4.3改變至7.0,視採樣之位置,或個體的性別而定。此pH在靠近顆粒層(SG)提高到7.0左右。此提高在鄰接SG的SC最後幾層中最引人注目,參見下文。同樣地,如本發明之複合物滲透進入SC,它們降解且同時地釋放與其結合之任何活性劑。
儘管在複合物已與磷酸鈣粒子結合,所釋放之活性劑保留其所要活性。因此,活性劑至磷酸鈣粒子之結合及釋放對活性劑產生實質上很少(如果有任何的話)的傷害。同樣地,活性劑之活性沒有減少至不利地影響其效用的程度,其中因與所給予之活性劑發生結合至磷酸鈣粒子所引起之任何活性的減少為10%或更小,諸如5%或更小及包括1%或更小,例如,如藉由活性檢定法測定,例如,如下述實驗段中所述。
在一些體系中,在複合物中活性劑與磷酸鈣粒子之結合保留一或多種所要的活性劑特徵,諸如穩定性。換句話說,複合物穩定活性劑,如相較於缺乏磷酸鈣粒子之對照組。
活性劑-磷酸鈣粒子複合物之磷酸鈣粒子為均勻剛性球形奈米孔洞磷酸鈣粒子。“均勻”是指粒子之形狀實質上不改變,所以粒子實質上具有相同的球形。“剛性”是指粒子很硬,致使它們不易曲折。術語“球形”係以其習知意義使用以表示在所有點的表面離中心實質上距離相等的圓體。感興趣者為其中平均直徑為20微米或更小,諸如10微米或更小,包括5微米或更小,在一些例子中其中平均直徑為4微米或更小,諸如3微米或更小,包括2微米或更小的磷酸鈣粒子。在所給予之磷酸鈣粒子組成物中,可存在直徑之分佈,其中在一些例子中多數(諸如60%或更大,75%或更大,90%或更大,95%或更大)之粒子具有在從0.01至20微米,諸如從0.1至10微米及包括從0.1至2微米之範圍的直徑。在一些例子中,具有2微米或更小之平均粒徑的粒子之比例為50數目%或更大,諸如70數目%或更大,包括90數目%或更大。
粒子為奈米孔洞。“奈米孔洞”是指粒子具有30%或更大,諸如40%或更大,包括50%或更大之孔隙度,其中孔隙度可在從30%至85%,諸如從40%至70%,包括從45%至55%之範圍,如使用如ASTM D 4284-88中所述之汞侵入孔隙計孔隙度測量方案“Standard Test Method for Determining Pore Volume Distribution of Catalysts by Mercury Intrusion Porosimetry”測量。孔隙度也以“孔洞體積(毫升/克)”描述且在該等例子中許多範圍在從0.1毫升/克至2.0毫升/克。在一些例子中,粒子具有致使其內表面積範圍在從10米2/克至150米2/克之孔隙度,諸如從20米2/克至100米2/克,包括30米2/克至80米2/克,如使用ASTM D3663-03觸媒及觸媒載體之表面積的標準測試方法中所述之BET氣體吸附表面積測定方案測定。孔洞直徑可改變,在某些例子中範圍在從2至100奈米,諸如5至80奈米,包括10至60奈米。除此之外,粒子可具有範圍在從0.2克/公分3至0.5克/公分3,諸如從0.25克/公分3至0.45克/公分3,包括從0.3克/公分3至0.4克/公分3之敲緊密度。該敲緊密度可使用標準ASTM WK13023-New Determination of Tap Density of Metallic Powders by a Constant Volume Measuring Method測量。

需要時,溶劑系統可以一或多種改質劑,諸如緩衝劑、pH調整劑(酸或鹼)、親水分子、疏水分子或具有疏水基及親水基之分子(例如,界面活性劑)改質。感興趣之緩衝劑包括但不限制於:HCl/檸檬酸鈉、檸檬酸/檸檬酸鈉、乙酸/乙酸鈉、K2HPO4/KH2PO4、Na2HPO4/NaH2PO4、硼砂/氫氧化鈉以及生物緩衝劑,例如,TAPS(3{[參(羥甲基)甲基]胺基}丙磺酸)、二羥乙甘胺酸(N,N-雙(2-羥乙基)甘胺酸)、參(參(羥甲基)甲基胺)、Tricine(N-參(羥甲基)甲基甘胺酸)、HEPES(4-2-羥乙基-1-哌乙磺酸)、TES(2-[參(羥甲基)甲基]胺基)乙磺酸)、MOPS(3-(N-嗎福啉基)丙磺酸)、PIPES(哌-N,N-雙(2-乙磺酸)、卡可酸酯(二甲基胂酸)、SSC(鹽水檸檬酸鈉)及MES(2-(N-嗎福啉基)乙磺酸);等等。
特定溶劑系統之成分及性質,諸如pH、組成物、溫度、等等可考慮一或多種與粒子複合之活性劑的性質而選擇,其中該等性質可包括活性劑溶解度、結構、pKa、logP、等等。
製備活性劑-粒子複合物之後,然後使用任何方便的方案將所得複合物與遞送組成物成分合併。所使用之特殊方案可視遞送組成物成分之性質而改變,其中在某些例子中裝載遞送組成物成分及活性劑之粒子可使用混合而合併以產生所要遞送組成物。雖然在組合期間溫度可改變,但在一些例子中溫度為80℃,諸如40℃或更小,諸如30℃或更小,例如,室溫或更冷。與遞送媒液合併之活性劑-粒子複合物的量可改變。在一些體系中,與遞送媒液合併之活性劑-粒子複合物的量係足以產生最終遞送組成物,其中活性劑-粒子複合物之量在從0.001至1000毫克/克,諸如0.1至200毫克/克之範圍且每克遞送組成物成分包括1至50毫克/克活性劑-粒子複合物。在某些體系中,該等避免螯合劑存在。調配物之pH為5.0或更大,諸如5.5或更大。
本發明之遞送組成物發現使用於將活性劑遞送至對象的局部位置之方法,其中局部位置可為皮膚表面部位或黏膜部位。在活性劑遞送至對象之局部部位中,本發明之遞送組成物可將活性劑-粒子複合物遞送至少進入在對象皮膚表面下方之表皮部位。同樣地,本發明之體系包括將裝載活性劑之粒子遞送進入對象角質層之方法,其中該方法可導致複合物遞送至對象深角質層及/或真皮。“進入角質層”表示複合物被遞送至在皮膚表面之下至少1個細胞層的區域。“深角質層”是指在皮膚表面之下2個或更多細胞層,諸如在皮膚表面之下5個或更多細胞層,包括在皮膚表面之下10個或更多細胞層之區域。在一些例子中,該等複合物係遞送至在皮膚表面之下2微米或更多諸如5微米或更多及包括15微米或更多的角質層區域。
本發明之體系包括將裝載活性劑之粒子遞送至對象角質層之的方法,其中該方法可導致複合物遞送進入對象之真皮。“進入真皮”是指複合物被遞送至在皮膚表面之下至少20個細胞層的區域。
一旦達成其目標皮膚部位時,在一些例子中該等活性劑結合粒子開始釋放其活性劑“載重量(payload)”。活性劑從粒子釋放可根據許多不同的機制發生。例如,在皮膚的環境中可逆轉試劑對粒子的任何結合交互作用。除了此機制之外或另外,皮膚的環境可破壞磷酸鈣粒子(例如,經由皮膚的梯度所引起之溶解),致使均勻剛性球形奈米孔洞粒子在酸性條件,例如,pH 5或更低,諸如4.5或更低,包括4.3或更低之條件,諸如角質層之生理酸條件下溶解。粒子在角質層中溶解所需時間可改變及在某些體系中,在從1分鐘至72小時,諸如10分鐘至24小時且包括30分鐘至12小時之範圍,超過該時段,活性劑從活性劑結合粒子釋放出來。本發明一特點包括所有活性劑之釋放。
本發明之方法因此導致活性劑遞送至少進入對象之角質層。在一些體系中,該等活性劑保留在角質層中以發揮其所要活性。在其他體系中,活性劑可在一或多個身體之其他目標部位發揮其所要活性。所感興趣之另外的目標部位包括另外的表皮區域,諸如但不限制於透明層、顆粒層、棘層(stratum spinusom)、基層及真皮。在某些體系中,該等活性劑係遞送至真皮之區域。在某些體系中,該等活性劑係遞送至真皮以下的區域,例如,進入皮下組織。
在一些例子中,活性劑可被全身性遞送至對象。當活性劑被全身性遞送至對象時,達到活性劑之治療血漿含量。活性劑之治療血漿含量視特定活性劑及要治療狀況而改變。在某些體系中,所達到之治療活性含量範圍從0.1至100微克,諸如1微克至20微克,諸如1奈克至1微克及包括10奈克至100奈克。
在實施本發明方法中,將遞送組成物施用於對象之局部區域且以足以如上所述產生活性劑至對象之所要遞送的方式維持於局部區域。在某些體系中,該局部區域為角質化皮膚區域。角質化皮膚區域,包括毛囊、汗腺及皮脂腺,可存在於各種原或損壞的皮膚部位,其中感興趣之部位包括但不限制於:四肢、雙臂、手、腿、腳;軀幹,例如,胸、背、胃;頭,例如,脖子、臉;等等。在某些體系中,該等區域將為頭部區域,諸如臉部區域,例如,前額、枕骨區域、嘴部四圍、等等。關於組成物施用之局部區域的面積可改變,在某些體系中,在從1毫米2至300公分2或更大,諸如從1至50公分2及包括從3至10公分2之範圍。
在實施標的方法中,對象可在給定的一段時間中被投予單一量或二或多個劑量。例如,在給定的一個月治療期,1或多個劑量,諸如2或多個劑量,3或多個劑量,4或多個劑量,5或多個劑量,等等可施用於對象之局部位置,其中該劑量可每週或每天施用或甚至可每天施用多次。
如相較於活性劑不是以與磷酸鈣粒子之複合物遞送的對照組,根據本發明之活性劑複合物的遞送可賦予一或多種優點。例如,在一些例子中該活性劑被穩定在磷酸鈣複合物中,致使其活性被維持。在一些例子中,將活性劑與磷酸鈣粒子複合成根據本發明之體系的複合物中提供活性劑至在其中不會正常地遞送之部位的遞送,例如,遞送進入角質層,如果該等試劑不存在於磷酸鈣粒子複合物中,其遞送會被限制在皮膚表面。在一些例子中,如相較於適當對照組,本發明之方法產生提高活性劑的滲透。適當對照組為一種包括相同活性劑及遞送媒液成分但沒有均勻剛性球形奈米孔洞磷酸鈣粒子之遞送組成物。在一些例子中,如相較於該等對照組,該滲透被提高2或多倍,諸如5或多倍,包括10或多倍之倍數。在其他體系中,該等複合物用作來自角質層的活性劑之控制釋放貯藏體(depot),藉此提供所要的活性劑之延長釋放及遞送輪廓。
雖然活性劑-磷酸鈣複合物在本文中已主要地依據其皮膚遞送應用之用途描述,但在一些例子中它們可用於其他應用。例如,本發明之活性劑-磷酸鈣複合物在一些例子中發現在活性劑非皮膚遞送至對象之用途。非皮膚遞送調配物的例子包括但不限制於:膠囊、錠劑、丸劑、小丸劑、菱形錠、粉劑、粒劑、糖漿、酏劑、溶液、懸浮液、乳液、栓劑、或其緩釋調配物,或任何適合於投藥至哺乳動物之其他形式。在一些例子中,為了投藥該等醫藥組成物係根據例行步驟被調配呈適合口服或靜脈內投予至人類之醫藥組成物。適當醫藥媒液及其調配方法的例子係描述於Remington:The Science and Practice of Pharmacy,Alfonso R. Gennaro編輯,伊斯頓麥克出版公司,賓夕法尼亞州,第19版,1995,第86、87、88、91及92章,以引用方式納入本文中。
標的方法及組成物可被使用於各種不同類型動物,其中該等動物典型為“哺乳動物”或“哺乳動物(mammalian)”,其中這些術語被廣泛地用以描述哺乳綱中的生物,包括食肉動物目(例如,狗和貓)、囓齒目(例如,小鼠、天竺鼠及大鼠)、複齒目(例如,兔子)及靈長目(例如,人類、黑猩猩及猴子)。在某些體系中,該等對象或病患為人類。
下列實例以說明方式且不限制的方式提供。
藉由在溫度、pH、壓力、氣體、攪拌速度、試劑濃度、添加速度及老化時間之控制條件下,將磷酸鹽複合物水溶液逐滴加入水性鈣複合物溶液或懸浮液製備磷酸鈣奈米-晶體漿料。藉由使用具有氣-液流體噴嘴之壓力噴嘴型噴霧乾燥器將漿料噴霧乾燥以形成球形多孔粉末。在300至900℃範圍之溫度下用氣體或電爐或窯將乾燥粉末燒結1至24小時範圍之時間。
圖1A及1B顯示所得2微米均勻剛性球形奈米孔洞磷酸鈣粒子(如上所述製備)之多孔結構,使用SEM(A)10,000 X、(B)50,000 X。圖2A及2B顯示2微米均勻剛性球形奈米孔洞磷酸鈣粒子(如上所述製備)的外部及內部結構,使用SEM(A)及TEM(B)(15000 X)二者。大(25-50米2/克)內及外表面積為實質上允許與活性劑結合的高能力。圖3顯示粒子之粒徑分佈,如以Coulter Multi-sizer 3粒子計數器測定及以掃描電子顯微鏡確認。平均粒徑為2微米。
磷酸鈣粒子結合廣泛範圍的生物分子且在一些例子中穩定該等生物分子。與磷酸鈣粒子之結合係以離子的交互作用為基礎。磷酸鈣粒子之官能基由帶正電鈣離子(Ca++)及帶負電磷酸根離子(PO4 -3)組成。此表示生物材料的陰離子化羧基之量在酸性條件下將減少。因此生物分子的陰離子化羧基和磷酸鈣粒子的鈣離子之間的結合將被減弱。此情形在鹼性條件下被生物分子的陽離子化胺基及磷酸鈣粒子的磷酸根官能基之間的交互作用逆轉。
pH及離子強度直接地影響磷酸鈣粒子及生物材料之間的結合。磷酸鈣粒子具有結合具有寬範圍分子量(例如,200至10,000,000)及等電點(例如,2.0至12)之生物材料的能力。
除了pH及離子強度,生物材料的分子量、形狀及位向也影響對磷酸鈣粒子的結合。例如,具有於90毫克/克之較低分子量的BSA及於較大分子量之DNA以1毫克/克之比率結合至磷酸鈣粒子。大生物分子諸如DNA之結合能力將以磷酸鈣粒子的外表面積測定。總結,影響磷酸鈣粒子和生物分子之間的結合之主要參數為pH、離子強度、立體化學作用及分子量。

使用上述說明的方案,如下表中所概述者製造活性劑-磷酸鈣複合物。
在角質層中,pH在從大約4.3至5.0之範圍且pH隨角質層深度減少。為了研究磷酸鈣粒子在類似於皮膚的條件下釋放活性劑,將二種溶菌酶磷酸鈣複合物於ph 4.8(0.5M乙酸鈉)及7.0(10mM Bis Tris)之緩衝液中暴露8小時。緩衝液以1毫升/小時速率流經樣品且每小時收集並藉由以UV光譜儀在280奈米監測而分析溶菌酶釋放。相等質量的溶菌酶磷酸鈣粒子複合物在pH 4.8緩衝液中渦旋攪動以評估樣品中的總可得溶菌酶。在pH 4.8下,觀察到溶菌酶從磷酸鈣粒子很快地釋放且大部份溶菌酶在第一小時內釋放。相比之下,在pH 7,在8小時內沒有觀察到溶菌酶從磷酸鈣粒子釋放。
如上所製備BSA-磷酸鈣複合物。用水及然後用0.2 M磷酸鈉鹽洗滌所得複合物以釋放任何結合BSA。用HPLC分析釋放之BSA及測定與非結合對照組相同,證明結合及釋放磷酸鈣粒子沒有不利地影響BSA活性。
步驟1.在燒杯中添加蜂蠟及Protachem IPP。開始加熱70℃-75℃直到均勻。冷卻到50℃。加SonneNaturalTM及Capmul MCM。混合直到均勻。
步驟2. 在分開的燒杯中添加1%水及核黃素單磷酸鹽。在R.T下混合直到均勻。加磷酸鈣粒子(用乳酸調整pH至pH7)。以500 RPM旋轉10分鐘。
步驟3. 在室溫下步驟1轉移至步驟2。混合直到均勻。
將11.9毫克的抗壞血酸溶解在30毫升的水中。將2克2微米磷酸鈣粒子懸浮在19.5毫升的水中及用HCl將pH調整到pH 7.14。將0.5毫升的抗壞血酸溶液(0.40毫克/毫升)混合在磷酸鈣粒子之懸浮液中,其將pH減少到7.05。包括10微克/毫升的抗壞血酸的磷酸鈣粒子之懸浮液(pH 7.05),在50℃下培養0.5至5小時。藉由在冰浴中冷卻懸浮液15分鐘將抗壞血酸之熱變性結束。為了從磷酸鈣粒子釋放結合之抗壞血酸以測量穩定效果,用HCl將各懸浮液之pH調整至pH 5及以3,000 rpm離心10分鐘。在265奈米測量所得上澄液。作為對照組,也培養10微克/毫升之抗壞血酸溶液且以相同步驟而沒有磷酸鈣粒子測量。抗壞血酸之活性係以下式計算:
抗壞血酸之活性(%)=(培養後上澄液之A265nm/培養前抗壞血酸之A265nm)×100
用10微米磷酸鈣粒子重複相同步驟。
該等結果總結於下表中。藉由在50℃下培養0.5小時將抗壞血酸之活性減少至36%;當在相同期間抗壞血酸附著至2微米磷酸鈣粒子時,此活性增加至85%。沒有磷酸鈣粒子之抗壞血酸在50℃下培養3小時之後完全地變性而沒有活性。然而,結合至2微米磷酸鈣粒子之抗壞血酸在50℃下經相同3小時期間具有48%活性。
磷酸鈣粒子在水中之懸浮液藉由擦拭10秒以一濃度施用於活人前臂。然後實施角質層之第一、第二及第三層的膠帶剝離。磷酸鈣粒子滲入角質層之第三層。磷酸鈣粒子在皮膚的低pH環境中慢慢地破裂且當粒子崩解成較小取代部分時可進一步滲入。磷酸鈣粒子投藥7小時之後,在顆粒層中Ca++沈積增加及檢測出現緊成群之Ca++沈積物,指示較大的崩解。
使用2微米磷酸鈣粒子。
將磷酸鈣粒子懸浮在70%乙二醇及30%乙醇中以製造10%懸浮液。將所得懸浮液局部地施用在無毛老鼠的皮膚表面上(1×1公分面積)。在施用期間,將老鼠給予麻醉劑。投予第一次施用(0.2毫升)及離開,第二次為投予4小時後在相同地方且為相同量。第一次施用七小時後,將老鼠犧牲,移除皮膚及以Ca++處理。定位方法依照EM技術。
用磷酸鈣粒子處理之前,表皮之檢驗顯示在顆粒層區域的典型Ca++梯度,而在此區域沒有可檢測的Ca++。如上所述在局部施用磷酸鈣粒子之後,在角質層可看到磷酸鈣粒子,且最小粒子移入較深層中。
氯化鈣係購自Sigma(C 7902)。使用磷酸鈣粒子(平均粒徑2微米)。
臨床測試最初使用5位人類對象(n=5)的專家組,接著另外3位的人類對象專家組(n=3)進行。每位專家組成員的標準先前為沒有皮膚疾病,包括異位性皮膚炎的歷史且個體在研究同時不允許使用任何不是溫和肥皂的皮膚保養產品。所有人類對象為皮膚類型2-3個染色。在志願者左右前臂上用神奇筆標記四個2.5公分2直徑面積。一個面積表示未經治療的面積。1%磷酸鈣粒子之水溶液(pH 5.0)(100微升)每日自我施用兩次於包含三個這些位置的右前臂。1% CaCl2之水溶液(pH 5.0)同樣施用於包含三個位置的左前臂。樣品用吸量管施用且在室溫下乾燥。室溫為大約21℃±1℃。相對濕度測定為約45%±5%。
實驗以每天施用兩次(一次在早晨及一次在傍晚)在星期一早上開始且持續至星期五早上。在星期五下午最後施用之後四小時,測量下列功能研究:在二個位置上,使用Tewameter(Courage & KhazakaModel #TM210)測量基本TEWL。用corneometer(Courage & Khazaka Model #CM820)測量SC水合作用,評估為電導,及用平面電極(皮膚-pH-計:Courage & Khazaka Model #PH900)測量SC表面pH。
角質層完整性:在這些初測量之後,各前臂上之二處理區域以連續D-Squame(CuDerm)膠帶剝離破裂,在各前臂上最多至18個。在各3次剝離之後測量TEWL,直到TEWL為大於最初基本讀數至少10倍。在TEWI中因剝離之改變速率為角質層完整性之測量。膠帶剝離之後,使用於pH 5之相同1%磷酸鈣粒子溶液再次挑戰右前臂上的區域之一,及使用於pH 5之相同%CaCl2溶液挑戰左手臂中二區域之一。最終挑戰之後,在2及4小時測量滲透阻隔恢復動力學。
1%磷酸鈣粒子之第三個處理位置及1%Cl2-處理位置上進行刮去生物檢體,接著評估表皮鈣梯度,包括半定量評估鈣在角質層的各種水平之量。
用於另外3位人類對象(n=3)之第二臨床研究的方案與最初5位人類對象專家組相同,除了使用3% CaCl2溶液(n=3)替代1% CaCl2之外。
觀察磷酸鈣粒子滲透至角質層的所有深度,而非常少的氯化鈣到達該等深度。顯微照相進一步顯示小量之鈣在角質層之更低水平釋放。這些結果顯示磷酸鈣粒子,“Ca之對準系統”,其不只幫助Ca滲透至SC之深度,且也表現為“Ca緩釋系統”。
此研究之目的為檢測在局部施用2微米均勻剛性球形奈米孔洞磷酸鈣粒子之後在角質層中的鈣,如上述實例1中所述。選擇氯四環素(來自Sigma之CTC,料號C-4881),因為其允許在角質層內藉由螢光將鈣顯影及因此以共聚焦顯微鏡檢測。
藉由將80毫克的CTC溶解在10毫升的水中製造CTC溶液。以3,000 rpm離心10分鐘移除不溶解CTC。將200毫克的粒子與2毫升的CTC溶液混合且旋渦攪動1分鐘。藉由用水洗滌接著以3,000 rpm離心10分鐘的三次循環移除游離CTC。將所得CTC結合粒子以1:10稀釋率懸浮在水。
在上述II.B中製備之懸浮液(大約0.2毫升)局部地施用在無毛老鼠皮膚上(1×1公分面積)。在施用期間,將老鼠給予麻醉劑。7小時之後,將老鼠犧牲且使用共聚焦顯微鏡(在380奈米波長激發的510奈米波長發射)檢查其皮膚。
所得共聚焦顯微鏡影像顯示於圖4中(在圖4中放大率為300 x)。圖4中所見之結果顯示鈣在局部施用2微米均勻剛性球形奈米孔洞磷酸鈣粒子之後滲透進入角質層。
2. 用STAY-C50-磷酸鈣複合物之膠帶剝離顯示STAY-C50之遞送至至少角質層的第10層。

在玻璃擴散室中之流通條件。
擴散室,實驗室玻璃裝置,型#LG-1084-LPCT,5公分2之暴露皮膚面積及4.5毫升之接受器隔間體積。
水套溫度維持在37℃。
8及16小時之施用間隔。
該室用石蠟膜封閉及以鋁套遮蔽光。

核黃素單磷酸鹽在PBS中於1.5毫克/毫升以遞送0.3-0.45毫克核黃素。
以吸量管施用50-100微升之體積的調配物。使核黃素-HYDRO磷酸鈣複合物施用空氣乾燥及然後將相同體積之0.5M乙酸鈉緩衝液吸量在皮膚上。
對照組由只有懸浮液的磷酸鈣粒子之相同施用組成。
皮膚表面,同時仍然保留在擴散室中,藉由吸量管重複投予而用1毫升PBS用洗滌二次。從擴散室移出皮膚,放置在鋁箔上及藉由將紙巾壓進皮膚3次用Kim紙巾擦乾。將皮膚包裝在鋁箔中並儲存用於分析。以吸量管從擴散室取出接受器液體。
洗滌及接受器液體:測定液體的大約體積。將樣品以10,000rpm旋轉30秒並將磷酸鈣粒子團塊分離、乾燥及秤重。將上澄液移出並以UV光譜儀分析。如果UV吸光度為飽和的(超過>2.0),則用水稀釋樣品。記錄於369奈米之UV吸光度值。(核黃素之*比UV吸光度峰為260奈米、375奈米及465奈米)。
皮膚:將皮膚切碎且與5毫升的10%三氯乙酸溶液混合。將樣品用超音波清洗機於50℃超音波清洗1小時。將樣品以10,000rpm離心10分鐘,移出上澄液及以UV光譜儀分析。如果UV吸光度為飽和的(超過>2.0),則用水稀釋樣品。記錄於372奈米之最大UV吸光度值。
如在皮膚施用側反面的細胞中核黃素代謝產物之外觀所檢測的,核黃素來自水溶液及來自磷酸鈣粒子複合物二者滲透通過皮膚。磷酸鈣粒子複合物引起活性的緩慢釋放。發現來自水溶液之組織含量高於來自磷酸鈣複合物,即使當磷酸鈣複合物施用於皮膚經8小時。該等結果圖解式地顯示於圖5中。
