Description
本發明係關於一種香豆素衍生化合物及含其之美容用組合物,以及更明確而言,係關於一種4-取代7-羥基香豆素衍生化合物,及其美容用途,例如皮膚美白劑。
許多人關心本身皮膚的色素沈積程度,例如,患有老人斑或雀斑的人們希望有較不明顯的色素斑。其他人則希望美白晒黑的皮膚或美白其自然的皮膚顏色。因應此需求,已進行許多黑色素細胞內減少色素產生的產品研發。然而,已確認的物質仍效果有限或產生不良副作用,例如,舉例而言,產生毒性或皮膚刺激性。因此,目前仍亟需一種可改善整體效果的新穎皮膚美白劑,以及可簡化其製程的藥劑。
間苯二酚衍生物具有美容皮膚和頭髮的效果。某些間苯二酚衍生物,特別是4-取代間苯二酚衍生物,係具有皮膚美白效果的實用美容用組合物。間苯二酚衍生物已述於許多專利公告案中,包括美國專利第4,959,393號;Hu等人,美國專利第6,132,740號;Bradley等人,美國專利第6,504,037;以及日本公告專利申請案JP 2001-010925及JP 2000-327557。間苯二酚衍生物係已知化合物並且可藉由各種方法輕易獲得,包括藉由一種方法:其中一飽和羧酸及間苯二酚係於氯化鋅的存在下縮合再以鋅汞合金/鹽酸還原所得到之縮合物(Lille等人,Tr. Nauch-Issled. Inst. Slantsev 1969,18號:127-134);或藉由一種方法,其中間苯二酚和一對應烷基醇於氧化鋁催化劑的存在下於200至400°C之高溫下反應(英國專利第1,581,428號)。源自香豆素的皮膚美白化合物揭示於美國專利公告號2004/0042983。這些化合物中某些對皮膚具有刺激性。
申請人目前已發現使用衍生自香豆素衍生物的化合物(但不侷限於此類方法)可產生皮膚美白效果。這些化合物的通式詳細討論如下。已發現羥基香豆素衍生化合物且特別指類似間苯二酚衍生物的4-取代7-羥基-香豆素衍生化合物極為有效且低皮膚刺激性並相當容易製造。在本文中稱這些化合物為「香豆素衍生間苯二酚衍生物」。本發明之香豆素衍生間苯二酚衍生物從未被用作為個人的保養品或皮膚的美白,特別是從未用於此一方面。
通式I化合物及含其之組合物具有美容效果,特別是皮膚美白效果,其刺激性較低並且相當容易製造。本發明提供一種皮膚美白的方法,其組合物除美容上可接受之載體外,另含有約0.000001至約50%的式I化合物,

I.4-取代-7-羥基香豆素的氫化作用
將在適當溶劑(例如,醋酸、乙醇、有機溶劑及其混合物)中的通式A化合物4-取代-7-羥基香豆素(較佳為4-烷基-7-羥基香豆素)及加入催化劑(例如,均質或非均質催化劑,如附著於適當基質的鈀和/或鎳及其混合物),充填入高壓反應瓶內。以氫氣加壓反應器(例如,約100至約800 psi)然後在25°C以上攪拌(例如,約25°C至約60°C)直至利用一適當分析方法(例如,薄層層析(TLC)、氣相層析(GC)、液相層析(LC)、氫氣耗量,及其組合)監控觀察到4-取代-7-羥基香豆素(較佳為4-烷基-7-羥基香豆素)完全消失為止。使反應混合物通過不溶性擔體(矽藻鹽、矽凝膠及其等組合)的過濾,在減壓下除去溶劑,然後利用純化方法(舉例而言,例如再結晶、蒸餾及其組合)純化產物。
將7-羥基-4-甲基香豆素(即式A1化合物,60克,0.34莫耳)及醋酸(350毫升)充填入Parr氫化儀(1升)內。加入溶於醋酸(150毫升)內之10% Pd/C(6.0克)懸浮液然後密封、抽空反應器然後以氫氣(4X)清洗。以氫氣加壓反應器至320 psi然後在30°C攪拌16小時,於不再消耗氫氣的反應點時以薄層層析(4%甲醇:氯仿)現出由起始材料形成的純化產物。抽空反應器,以氮氣清洗然後通過矽藻土過濾混合物。除去溶劑後獲得白色固體(60.5克,100%)。從醋酸乙酯:正己烷再結晶而產生白色純化固體產物:溶點109-110°C;1

下列範例僅供例示而非限制本發明之原則,以說明執行本發明的最佳模式。
下列的化合物係用於所有下列的範例。根據說明於範例1的程序製備這些化合物。
利用本文中稱為4-甲基7-羥基香豆素的式A1化合物作為起始材料製備本發明之香豆素衍生間苯二酚化合物。
製備本發明範圍內的美容用組合物。
藉由攪拌並加熱相位A成分至70至85°C製備示於下表的基礎配製物。在攪拌中於分開容器內加熱相位B成分至70至85°C。然後,在兩者相位保持在70至85°C下將相位A加入相位B內。混合物在70至85°C下至少攪拌15分鐘,然後冷卻。
製備本發明範圍內的其他美容用組合物。
依如下方法製備範例3的組合物:1.將相位A加熱至80°C;2.在分開容器內將相位B加熱至75°C;3.不加熱下將B加入A然後混合30分鐘;4.在50°C下加入相位C然後混合10分鐘。
製備本發明範圍內可用於本發明方法的一組其他組合物並列舉於下表中。
此範例顯示利用4-甲基7-羥基香豆素衍生間苯二酚化合物之皮膚美白效果,作為本發明方法的皮膚美白劑。利用細胞性檢測法進行此試驗。
下列試驗為利用B16白鼠黑色素細胞測定皮膚美白劑的效果。將B16細胞以每孔5,000個細胞的密度置入96-孔微滴定盤內,然後在37°C且存在有5% CO2
之含10%小牛血清和1%氰芐鏈黴素的Dulbecco改良伊格爾培養液(無酚紅)內培養隔夜。培養24小時之後,以含美白劑之新鮮生長培養液取代原培養液。全部培養液在培養72小時之後可看見對照組產生黑色素。將含黑色素培養液轉置於乾淨的96-孔培養盤內然後讀取530 nm下的吸光度進行定量。藉由測定乳酸脫氫酶(LDH)觀察細胞活性以確保黑色素的減少非導因於細胞毒性。
從列於上述的結果顯示本發明之香豆素衍生間苯二酚化合物可減少黑色素之合成至約和4-乙基間苯二酚的相同程度。
抑制香菇酪胺酸酶可降低黑色素的合成,因而具有皮膚的美白效果。此實驗可顯示本發明之香豆素衍生間苯二酚衍生物的效果。
在96-孔滴定盤的各孔內加入150微升磷酸鹽緩衝液(100毫莫耳,pH 7.0)、10微升左旋-DOPA(左旋-3,4-二羥苯丙胺酸,10毫莫耳),以及20微升的皮膚美白劑(溶於作為對照組的乙醇)。以475 nm初步測定其背景吸光度之後,加入20微升香菇酪胺酸酶(Sigma T-7755;6050單位/毫升)然後於室溫中培養。
於下列的時間點在475 nm讀取其吸光度:0、2、4和6.5分鐘。資料係以475-nm吸光度對時間(分鐘)繪圖,然後計算其線性斜率(△Abs 475 nm/分)。以個別未處理乙醇對照組反應的百分比表示其值。
對照組%=×100%
資料顯示式II和D1之香豆素衍生化合物實質上和4-乙基間苯二酚同樣有效,兩者化合物均具有極佳的皮膚美白效果。以香菇酪胺酸酶檢測法測定時,衍生自7-羥基-3,4-二氫-4-甲基香豆素(B1)化合物的本發明化合物較不具美白效果。
此範例說明一種本發明的創新方法。R-基如先前上文中所定義。
