The present application provides SOX9 inhibitor compounds and compositions and methods of use thereof. In certain aspects, the SOX9 inhibitor is a peptide comprising a portion of the SOX9 dimerization motif. In other aspects, the SOX9 inhibitor is a compound of the general formula I

##STR00001##

where one A is H and the other is:

##STR00002##

and the remaining substituents are as defined in the application.

Provided are small molecule inhibitors for amplifying hematopoietic stem cells (HSCs) and a combination thereof. The small molecule inhibitors and the combination thereof can maintain the sternness of hematopoietic stem cells while promoting the in vitro amplification of hematopoietic stem cells (HSCs).

A microneedle applicator is provided. A microneedle applicator according to an embodiment of the present invention comprises: a microneedle array; an operation member disposed on the upper portion of the microneedle array and operating such that a user applies an external force so as to insert a microneedle into skin; a housing for accommodating the microneedle array and the operation member; a first guide member disposed in at least one position on a lateral portion of the operation member or on a lateral portion of an interworking member of the operation member; and a second guide member which is disposed on the inner surface of the housing in a position corresponding to the first guide member so as to be engaged with the first guide member, and allows the first guide member to slide so as to prevent the microneedle array from rotating or horizontally distorting when the microneedle array uniformly vertically descends due to the external force.

Compounds with the following structures ##STR00001##
and their analogs are provided. Compositions that include these structures can be used to inhibit glucose transporters and stop or decrease the proliferation of cancer, treat possible organ rejection and treat autoimmune disease.
