The present invention provides a compound represented by the following Chemical Formula 1 or a pharmaceutically acceptable salt thereof which can be effectively used for preventing or treating obesity or metabolic syndrome, and a pharmaceutical composition comprising the same.

##STR00001## in Chemical Formula 1, R.sub.1 and R.sub.2 are the same as defined in the specification.

There is herein provided a compound of formula (I) or a pharmaceutically acceptable salt thereof, for use in the treatment of hyperglycaemia or a disorder characterized by hyperglycaemia, such as type 2 diabetes, wherein X, R.sup.1, R.sup.2, R.sup.3 and n have meanings as provided in the description.

##STR00001##

The present disclosure provides mimic molecules that are capable of specifically targeting a FAM19A5 protein, and thereby, inhibiting, reducing, and/or dissociating the interaction between members of the LRRC4 protein family and the FAM19A5 protein. The present disclosure also provides methods for promoting neurite outgrowth, by administering a mimic molecule described herein.

The present invention provides a compound represented by the following Chemical Formula 1 or a pharmaceutically acceptable salt thereof which can be effectively used for preventing or treating obesity or metabolic syndrome, and a pharmaceutical composition comprising the same. ##STR00001## in Chemical Formula 1, R.sub.1 and R.sub.2 are the same as defined in the specification.

A compound represented by chemical formula 1, a salt, a stereoisomer, a solvent or a hydrate thereof, an antibacterial composition including the compound, and uses thereof are disclosed. The antibacterial composition is suitable for inhibiting bacterial infections, preventing, alleviating or treating bacterial infectious disease, and for preventing, alleviating or treating inflammation caused by a bacterial infection. The compound specifically binds to p62 protein so as to activate p62, thereby increasing the activity of autophagy, which is inhibited by a bacterial infection, and thus has antibacterial activity against various bacteria, can inhibit bacterial infectivity and has the excellent effect of enabling prevention, alleviation or treatment of bacterial infectious disease and inflammation caused by an infection.
