Abstract
具有右式的腋臭抑制剂,其中R具有如说明书所给出的相同含义。
Description
本发明涉及可用于预防或抑制人体恶臭、特别是人体腋臭的化合物。
已知新鲜汗液是无臭的,气味仅在汗液与皮肤细菌(例如葡萄球菌属和棒状杆菌属细菌)接触后产生,据信存在于汗液中的无臭分子被定居于腋窝的细菌所降解。公认的是(Labows et.al.,Cosmet.SciTechnol.Ser.(1999),20:59-82)非常令人不快的恶臭主要是由棒状杆菌属细菌从新鲜汗液中释放出来的。被认为与恶臭有关的主要成分包括挥发性类固醇、挥发性硫化合物和短链支链脂肪酸。
有人建议通过根除负责产生气味的细菌来治疗恶臭。事实上,商业上可得到的美容除臭剂经常含有一般抑制皮肤微生物丛生长的抗菌化合物。目前用在除臭剂产品中的抗菌化合物例如包括三氯生(2,4,4’-三氯-2’-羟基-二苯基-醚)。不过,使用抗菌剂的缺点是有可能破坏皮肤天然微生物丛的平衡。
已知脂肪酸、特别是短链支链脂肪酸在腋臭中起一定作用,是陈腐汗液中特别恶臭的组分。在未决申请PCT/CH02/00262中,申请人公开了一种酶,所述酶介导将见于汗液中的无臭化合物转化为这些恶臭脂肪酸的过程。在该未决申请中,也公开了一类广泛的具有作为该抑制剂的活性的化合物。
不过,仍然需要发现其他对上述酶显示良好抑制性质的化合物。
因此,本发明在第一方面提供式(I)化合物
其中R是取代的烷基、苄基或烯丙基残基,其选自由下列基团组成的组:
a)壬基;
b)4,4,4-三氟-丙基;
c)2-甲基-4-苯基-丁基;
d)4-三氟甲基-苯基;
e)五氟苯基;
f)4-氟-苯基;
g)萘-2-基;
h)联苯-2-基;
i)5,5,7,8,8-五甲基-5,6,7,8-四氢-萘-2-基;
k)5,5,8,8-四甲基-5,6,7,8-四氢-萘-2-基;
l)1,1,3,3-四甲基-二氢茚-5-基;
m)苯乙烯基;
n)2,6-二甲基-庚基;
o)2-(4-叔丁基-苯基)-1-甲基-乙烯基;
p)2-(4-异丙基-苯基)-1-甲基-乙烯基;
q)1-(1,7,7-三甲基-二环[2.2.1]庚-2-基)-乙基;
r)2-(4-异丁基-苯基)-1-甲基-乙烯基;
s)2-(2-异丙基-苯基)-1-甲基-乙烯基;
t)2-苯基-乙基;
u)环己基-甲基;
v)2,2-二甲基-丙基;
w)2-(五氟苯基)-乙基;
x)3-苯基-丙基;
y)庚基;
z)4-异丙基-环己-1-烯基;
za)癸基;
zb)己基;
zc)反式-4-异丙基-环己基;
zd)5-乙基-2-甲基-庚基;
ze)2,6,10-三甲基-十一烷基;
zf)1-甲基-3-(2,2,3-三甲基-环戊基)-丙基;和
zg)辛基。
式(I)化合物含有手性原子,因此它们可以异构体混合物形式存在,或者它们可以纯立体异构体形式存在。最优选的是化合物在羧基α位碳原子上具有S-构型。
如上所述,本发明化合物可以作用于酶,由此降低该酶裂解汗液中引起恶臭性酸从无臭新鲜汗液中释放的化合物的能力。如上述未决申请所述的酶是从能够定居于腋窝的棒状杆菌属细菌中分离的,特别是某些棒状杆菌,更确切为纹带棒杆菌(Corynebacterium striatum)Ax 20,它们已于2001年4月26日提交至国际保藏机构DSMZ-DeutscheSammlung von Mikrooganismen und Zellkulturen GmbH,D-38124Braunschweig保藏。由国际保藏机构所提供的入藏号为DSM 14267。这种酶存在于细胞内,通过细胞膜的机械破坏能够从细胞中释放出来。因而,它可以从野生型菌株所得细胞提取物中分离,尤其可从人腋窝分离的棒状杆菌菌株,特别是纹带棒杆菌Ax 20中分离。作为替代选择,它可以借助重组手段产生,这是本领域技术人员所熟知的。
这种酶的氨基酸序列如SEQ ID No.1所列,编码这种酶的核酸序列如SEQ ID No.2所列,这两种序列如下所示。
本发明化合物在浓度为约1至500nM、更确切为5至500nM、例如9至150nM时在体外显示酶抑制作用。此外,根据残基R的亲脂性,化合物可以穿透产生该酶的细菌的细胞壁,因此它们也是体内有效的。
事实上,残基R的属性似乎影响化合物穿透定居于腋窝、与恶臭产生有关的不同细菌细胞壁的能力。例如,其他棒状杆菌菌株、例如牛棒杆菌和杰氏棒杆菌,或者见于腋窝微生物丛的葡萄球菌属细菌,也产生相关的酶,它们本身介导其中L-谷氨酰胺衍生物在Nα处裂解的生物化学反应。本发明化合物可以干扰多种细菌菌株的细胞过程,由此抑制或防止来自这些来源的恶臭。
化合物作为抑制剂的体外活性可以根据它们的IC50值或者它们的Ki值加以测量,这两种量度都是本领域技术人员所熟知的。正如所熟知的,IC50值表示抑制剂在给定底物浓度下降低酶速度达一半所需的浓度。该数值依赖于底物对酶的亲和性,这反映在底物的Km值中。按照这种方式,可以通过测量IC50、然后按照下式计算而测定给定底物和给定底物浓度的Ki值
化合物在细菌细胞中的摄取和其中所含酶的抑制可以利用基于静止期活细胞的测定法加以测量。因而,可以将细胞与抑制性化合物和底物(也就是见于汗液中的物质,它们在被酶裂解时生成恶臭性酸)一起培育,可以在不同抑制剂浓度下测量酸的释放。通过对比用活细胞所得IC50值与由分离酶所得IC50值,可以评估化合物进入细菌细胞的容易性。
本发明化合物可以添加在任何美容与个人护理产品中,例如除臭药棒、滚擦剂(roll-ons)、泵式喷雾剂、气雾剂、除臭皂、药粉、溶液、凝胶、霜剂、药贴、香膏和洗剂,以增强这些产品的除臭效果。优选地,本发明化合物在所述产品中的用量可以是约0.01至0.5重量%。
除了抑制剂以外,上述产品还可以包含本领域已知的抗菌剂,例如三氯生。这些产品还可以包含皮肤病学上可接受的成分,例如普遍用在这些类型产品中的那些。这类附加成分的实例包括香料、着色剂、遮光剂、缓冲剂、抗氧化剂、维生素、乳化剂、UV吸收剂、硅酮等。也正如所熟知的,全部产品均可以被缓冲至所需的pH。
除了抑制剂以外,除臭香水还可以包含乙醇和香料。香料的含量可以是1至10%,乙醇的含量可以补足至100%。
典型无乙醇除臭药棒中的附加成分可以包括多元醇,例如丙二醇;其衍生物,例如丙二醇-3-肉豆蔻基醚(Witconol APM);水;表面活性剂,例如硬脂酸钠;和香料。多元醇的含量可以是30至40%;多元醇衍生物的含量同样可以是30至40%;水的含量可以是约10至20%;表面活性剂的含量可以是5至10%;香料的含量可以多达10%。
典型止汗药棒可能含有作为附加成分的乙二醇单硬脂酸酯(例如5至10%)、Shea脂(例如3至5%)、Neobee 1053(PVO International)(例如约12至15%)、Generol 122(Henkel)(例如约3至7%)、二甲聚硅氧烷(DC 345)(例如30至40%)、倍半氯水合铝(例如约15至20%)和香料(例如1至10%)。
止汗气雾剂可以含有乙醇,例如约10至15%;四氯水合锆铝,例如3至5%;Bentone 38,例如约1至2%;香料,含量如上所述;和一种烃推进剂,例如S-31,补足至100%,基于全体气雾剂组成计。
止汗泵式组合物可以含有倍半氯水合铝,例如15至25%;水,例如50至60%;Triton X-102(Union carbide),例如1至3%;二甲基异山梨醇(ICI),例如15至25%;和香料,含量如上所述。
上面提到的所有百分比均为wt%。
因此,本发明涉及式(I)化合物和/或含有它们的组合物用于消除或抑制恶臭的用途。本发明还涉及组合物,其中包含臭味抑制量的充当所述酶抑制剂的抑制剂化合物,和皮肤病学上可接受的载体,它们一般是美容与个人护理产品领域所熟知的。
本发明在其另一方面还提供抑制腋臭的方法,包含提供一种组合物供施用于需要治疗的个人皮肤,所述组合物含有抑制剂化合物及其皮肤病学上可接受的载体,所述化合物选自一种或多种上述式(I)化合物。
