The signal transducer and activator of transcription 3 is a constitutively activated oncogenic protein in various human tumors and represents a valid target for anticancer drug design. In this study, we have achieved a new type of STAT3 inhibitors based on structural modifications on shikonin scaffold, guided by computational modelling. By tests, PMMB-187 exhibited a more outstanding profile than...
The high incidence of cancer and the side effects of traditional anticancer drugs motivate the search for new and more effective anticancer drugs. In this study, we synthesized 17 kinds of aryl dihydrothiazol acyl shikonin ester derivatives and evaluated their anticancer activity through MTT assay. Among them, C13 showed better antiproliferation activity with IC 50 =3.14±0.21μM against HeLa...
