Provided is a small molecule compound as represented by structural formula (I). The product of the present invention in various concentrations and dosages can achieve an obvious change in the growth period of hairs, promoting the growth of the hairs, thus exhibiting an obvious effect of promoting hair growth. In addition, changes in the weight of a mouse in each group are slow, indicating that the test compound does not cause weight loss in an animal.

The compound of the formula (I-1):

##STR00001##

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.sub.2 antagonistic activity. The compound may therefore be used as a therapeutic agent for S1P.sub.2-mediated diseases such as diseases resulting from vascular constriction, fibrosis, and respiratory diseases.
