The present invention relates to certain pyrrolopyrimidine derivatives, pharmaceutical compositions containing them, and methods of using them, including methods for the treatment of proliferation disorders and other diseases related to the dysregulation of kinase (such as, but not limited to, EGFR (including HER), Alk, PDGFR, BLK, BMX/ETK, BTK, FLT3(D835Y), ITK, JAK1, JAK2, JAK3, TEC and TXK) and/or the respective pathways.

The present invention provides a 6-dithio-substituted-2′-deoxyguanosine compound and a preparation method thereof and use thereof in anti-tumor drugs. According to the present invention, a series of brand-new thioredoxin-1 (Trx-1) inhibitors are designed and synthesized by using 2′-deoxyguanosine as a structure mother nucleus. The compound according to the present invention is a structure of formula I, and Trx-1 activity inhibition testing is performed on the type of compounds, showing apparent inhibitory activity. It is indicated from in vitro and vivo researches that these compounds show significant anti-tumor effects on multiple types of tumors, can be applied to drugs for tumors related to human body cell proliferation, and provide a new path for the research of anticancer drugs. ##STR00001##
