The present invention provides a compound consisting of a moiety and a group chemically bonded to said moiety, wherein said moiety contains a compound having low activity following oral administration or its parent scaffold and said group has the following general formula (1):
in which
R1represents a hydrogen atom, etc.,
R2represents a C1-C7 halogenoalkyl group, etc.,
mrepresents an integer of 2 to 14, and
nrepresents an integer of 2 to 7,
or enantiomers of the compound, or hydrates or pharmaceutically acceptable salts of the compound or enantiomers thereof. The above compound is advantageous in pharmaceutical use because the group of general formula (1) allows compounds such as anti-estrogenic ones to show a significantly increased activity following oral administration when attached to the parent scaffolds of the compounds.
本发明提供了一种由一个分子和一个与所述分子化学键合的基团组成的化合物,其中所述分子包含口服后活性较低的化合物或其母体支架,所述基团具有以下通式(1):
其中
R1 代表氢原子等
R2 代表 C1-C7 卤代烷基等、
m 代表 2 至 14 的整数,以及
n 代表 2 至 7 的整数、
或化合物的对映体,或化合物或其对映体的水合物或药学上可接受的盐。上述化合物在医药用途方面具有优势,因为通式(1)的基团可以使诸如抗雌激素类的化合物在口服后附着在化合物的母支架上,显示出显著增加的活性。
