  • Patent number: 10835520
    Abstract: 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 S1P2 antagonistic activity. The compound may therefore be used as a therapeutic agent for S1P2-mediated diseases such as diseases resulting from vascular constriction, fibrosis, and respiratory diseases.
