Phenyl derivative
The compound of the formula (I-1): wherein all the symbols have the same meanings as described in the specification, has two cyclic groups, particularly phenoxy groups at specific substitution positions and thus has high human S1P 2 antagonistic activity. The compound may therefore be used as a therapeutic agent for S1P 2 -mediated diseases such as diseases resulting from vascular constriction, fibrosis, and respiratory diseases.
