Description
ヒトの肺は、多数の小さな気嚢(肺胞と呼ばれる)から構成されており、そこで気体は血液と肺の空気空間との間で交換される。健常な個体において、この交換は、肺が呼気の終末に虚脱することを防止するタンパク質含有サーファクタント複合体の存在によって媒介される。
本発明は、脂質担体、ならびにネイティブなサーファクタントタンパク質SP−Cの特定のポリペプチドアナログと3〜8個、好ましくは4〜5個の疎水性アミノ酸残基および1個の塩基性アミノ酸残基から構成される反復単位の配列を含むポリペプチドとの組み合わせを含む再構成サーファクタントに関する。
a)脂質担体;
b)一般式(I):
[式中、
Xは、I、LおよびnLからなる群より独立して選択されるアミノ酸残基であり;
Bは、K、R、H、W、F、YおよびOrnからなる群より独立して選択されるアミノ酸残基であり;
Sは、エステル結合を介して側鎖に連結された12〜22個の炭素原子、好ましくは16個の炭素原子を含むアシル基で場合により置換されており;
Ωは、Mまたは硫黄原子上で酸化されたM、I、LおよびnLからなる群より選択されるアミノ酸残基であり;
aは、1〜8の値を有する整数であり;
bは、1〜19の値を有する整数であり;
e、f、gおよびpは、0または1の値を有する整数であり;
ただし、XaBXbは、最大22アミノ酸を有する配列である]
で表される配列を有する少なくとも20アミノ酸残基かつ40アミノ酸残基以下のポリペプチド;
c)一般式(II):
[式中、
Uは、L、I、nL、V、A、MおよびFからなる群より独立して選択されるアミノ酸残基であり;
Bは、K、R、HおよびOrnからなる群より独立して選択されるアミノ酸残基であり;
aは、3〜8、好ましくは4〜5の値を有する整数であり;そして
xは、2〜6、好ましくは3〜4の値を有する整数である]
で表される配列を含む少なくとも12アミノ酸残基かつ60アミノ酸残基以下のポリペプチド。
外因性サーファクタント調製物を用いるインビボ処置後の呼吸機能を以下の2つのパラメーターを測定することによって行う:
i)肺コンプライアンスの指標である一回換気量、および
ii)呼気の終末での肺胞空気膨張または開存性の、従って呼気の終末での肺胞における安定なリン脂質膜を形成する能力の指標である肺気量。
