Abstract |
Chemical biology approach is one of most powerful methods to discovery biologically active molecules. By conjugation of HTS (high throughput screen), this approach can leverage automation to search drug like compounds based on cell based or biochemical based assay. Discovering active compounds that affect biological functions will lead to identification of novel biologically functional components and establish the basis for therapeutic strategies. Beta cell dysfunction or death plays crucial roles in the progression of type 1 and type 2 diabetes. Current anti-diabetic drug cannot prevent the progression of beta cell dysfunction and death. In diabetes, major cause of beta cell dysfunction and death is related with endoplasmic reticulum (ER) stress. By using chemical biology approach, we identified quinazoline compounds as a novel class of β-cell protective agents against ER stress-induced dysfunction and death. Through extensive SAR optimization, 2,4-diaminoquinazoline markedly protects β-cells against ER stress-induced dysfunction and death with 80% maximum rescue activity. We are currently under further investigation for animal model studies to evaluate efficacy of the compound. |
