Title: Triazole derivative and use thereof

Description:
TECHNICAL FIELD 
     The present invention relates to a novel triazole derivative or a salt thereof. The triazole derivative or the salt thereof according to the present invention induces or promotes browning of white adipocytes, and differentiates stem cells, embryonic cells, or preadipocytes to brown adipocytes or beige adipocytes. A composition comprising the triazole derivative or the salt thereof according to the present invention can treat, prevent, or alleviate obesity, obesity complications, diabetes, dyslipidemia, fatty liver, hypertension, metabolic syndrome, and insulin resistance syndrome. 
     BACKGROUND ART 
     Adipocytes can be classified into white adipocytes, brown adipocytes and beige adipocytes. The white adipocytes serve to store energy in the form of triglycerides. However, if the number of white adipocytes is excessively increased or functional abnormalities occur, it can cause obesity or metabolic related diseases such as diabetes, dyslipidemia, insulin resistance syndrome, fatty liver, etc. On the other hand, the brown adipocytes have a structure containing more mitochondria and small-sized lipid droplets than white adipocytes, and are known to play a role in maintaining body temperature through thermogenic metabolism of these mitochondria. 
     The process of converting white adipocytes to brown adipocytes after receiving heat-generating stimulation such as cold is called browning. Brown adipocytes in which white adipocytes are converted through the browning process are referred to as beige adipocytes. 
     The applicant has disclosed a butein or butein derivative in US Patent Publication No. US 2015/0374643 A1 (2015 Dec. 31) as a compound that has a function of inducing brown adipocytes and inducing differentiation from white adipocytes into beige adipocytes. 
     Technical Problem 
     The inventors have performed experiments using various compounds for the purpose of increasing the number of brown adipocytes or beige adipocytes and increasing their cell activities. 
     As a result, it was surprisingly proved that the purpose can be achieved by particular triazole derivative compounds or a pharmaceutically or sitologically acceptable salt thereof, leading to the present invention.

     Stem cells, embryonic cells, or preadipocytes may be differentiated into white adipocytes or otherwise into brown adipocytes or beige adipocytes depending on factors such as surrounding environment or stimulus. However, when the composition according to the present disclosure is administered, the process of differentiation into brown adipocytes or beige adipocytes is induced or promoted. As a result, the number of brown adipocytes or beige adipocytes in adipose tissue is increased to a significant level, and accordingly, intrinsic activity such as heat generation or body temperature maintenance action can be efficiently increased. 
     The effect of inducing or promoting differentiation of stem cells, embryonic cells or preadipocytes into brown adipocytes or beige adipocytes which is exhibited by the composition according to the present disclosure can be obtained both in vitro and in vivo when administered to a subject.

     Example: Adipocyte Differentiation Induction Experiment 
     In order to prove whether the compounds prepared above can differentiate stem cells or preadipocytes into beige adipocytes, the inventors constructed a cell experimental model. C3H10T1/2 cells exhibit fibroblast morphology when cultured, functionally similar to mesenchymal stem cells. 
     C3H10T1/2 cells were commercially purchased, and then differentiated into white adipocytes. The differentiated adipocytes were treated with the compounds obtained in the Preparation Examples at a concentration of 20 μM. A group treated with DMSO at a concentration of 20 μM and a group treated with butein at a concentration of 20 μM were used as a control group, respectively. The butein was reported as a material that increases the expression level of UCP1 in US Patent Publication No. US 2015/0374643 A1. 
     While the UCP1 (uncoupling protein-1) is contained in the mitochondria of brown adipocytes or beige adipocytes, it is difficult to find UCP1 in white adipocytes having little mitochondria. Therefore, by measuring the expression level of UCP1, it is possible to determine whether preadipocytes have differentiated into white adipocytes or otherwise brown adipocytes or beige adipocytes. The higher the expression level of UCP1, the more differentiated preadipocytes into brown adipocytes or beige adipocytes. 
     The relative expression levels of UCP1 measured by real time PCR are shown in Table 1 below. As a result, the group treated with the triazole derivatives or salt thereof according to the present disclosure showed a remarkably higher expression level of UCP1 compared to the DMSO control group. In addition, the effect was significantly higher than that of butein, which is known to increase the expression level of UCP1.
