| 摘要 |
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 whichR1 represents a hydrogen atom, etc.,R2 represents a C1-C7 halogenoalkyl group, etc.,m represents an integer of 2 to 14, andn represents 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.
