| Research Abstract |
Macrophages are variously activated in disease environment. For example, M1-activated macrophages are involved in obesity and atherosclerosis, whereas M2-activated tumor-associated macrophages promote tumor progression. To develop new therapeutic strategies we identified several compounds that regulate M1- or M2-activation of macrophages by screening the library of natural compounds. Among them, colosolic acid and onionin A suppressed tumor progression by means of suppressing STAT3 activation. These two compounds significantly suppressed subcutaneous tumor development and lung metastasis in a murine sarcoma model. Through these results, application of colosolic acid and onionin A is considered a potential new anticancer therapy targeting macrophage activation.
