WebCardamonin is a novel inhibitor of STAT3 that locks the nuclear translocation and dimerization of STAT3 in CD133 + GSCs [304]. It inhibits proliferation and induces apoptosis in CD133 + GSCs. In combination with temozolomide, the apoptotic effect is further enhanced [304]. WebThe selective STAT3 inhibitor Stattic and the mitochondria-targeted inhibitors Mitocur-1 and Mitocur-3 (curcumin conjugated with triphenylphosphonium lipophilic cations) suppress both degranulation and cytokine production by MCs [7,16]. Mitocur-1 and Mitocur-3 have previously been shown to be more toxic to breast cancer cells compared to non ...

WebMay 14, 2024 · STAT3 small molecule inhibitors have been developed and shown excellent anticancer activities in in vitro and in vivo models of TNBC. This review discusses the recent advances in the understanding of STAT3, with a focus on STAT3’s oncogenic role in TNBC. WebHere, we report that nifuratel, an antiprotozoal and antifungal drug, is a potent inhibitor of STAT3. We found that nifuratel significantly suppressed proliferation and induced apoptosis of gastric cancer cells. Studies of the mechanism of action of nifuratel indicated that it acts by inhibiting the constitutive and interleukin-6-induced STAT3 ...
WebNov 11, 2024 · Inhibitors of upstream JAK kinases, such as ruxolitinib, can decrease the phosphorylation and activity of STAT3. However, ruxolitinib has a relatively weak inhibitory effect on STAT3 and demonstrates only a modest clinical benefit in patients with STAT3-driven malignancies (. Vainchenker et al., 2024. ). WebApr 29, 2011 · Previous reports with STAT3 siRNA or kinase inhibitors such as Janus activated kinase inhibitors in these tumor cells were limited to proliferation analysis in vitro . This is the first demonstration in vivo that direct STAT3 inhibition in ABC-like DLBCL suppresses tumor growth. Our data also suggest that direct inhibition of STAT3, rather …
WebWhile STAT3 is a promising anticancer drug target, it is a very difficult protein to inhibit using traditional drug-like molecules. This is because STAT3 lacks an enzyme active site where inhibitors would normally bind ().Instead, STAT3’s activity is mediated by protein-protein and protein-DNA interactions that involve large, relatively flat regions of the protein’s surface (). WebApr 18, 2024 · STAT3 activation is maintained through signal molecules that negatively regulate STAT3, including suppressor of cytokine signaling (SOCS) which inhibits STAT3 at the transcriptional level, while protein inhibitor of activated STAT (PIAS) inhibits by directly binding to STAT3 and SHP-1/2.
