应用
STA-21 has been used as a signal transducer and activator of transcription 3 (STAT3) inhibitor to study its effects on glioblastoma and primary glioblastoma cells. It has also been used as a STAT3 dimerization inhibitor to study its effects on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) production in human lung cancer cell line.
生化/生理作用
STA-21 is a STAT3 inhibitor that reduces the constitutively high STAT3 transcriptional activity in Caov-3 and MDA-MB-435s cultures (by 9.125- and 5.765-fold, respectively, post 48-hr 20 μM treatment) by disrupting STAT3 homodimerization, an essential process for STAT3 nuclear localization and DNA-binding activity. STA-21 selectively inhibits the growth and survival of breast carcinoma cells with constitutive Stat3 signaling (26%, 25%, 56% apoptotic cells, respectively, in MDA-MB-231, MDA-MB-435s, and MDA-MB-468 cultures, respectively, post 48-hr 20 μM treatment) but not those without (<10% apoptosis in MCF7, MDA-MB-453, HSF cultures post 48-hr 20 μM treatmen). STA-21 is reported to alleviate autoimmune inflammation in a murine model of rheumatoid arthritis (RA; 0.5 mg/kg; 3X i.p./week) and reduce airway inflammation in allergic mice with psoriatic inflammation (20 μg/mouse/day topically) in vivo.

Constitutive activation of signal transducer and activator of transcription 3 (Stat3) signaling pathway plays an important role in several human cancers. Activation of Stat3 is dependent on the phosphorylation at the tyrosine residue 705 by upstream kinases and subsequent nuclear

Stat3 has been classified as a proto-oncogene and constitutive Stat3 signaling appears to be involved in oncogenesis of human cancers. However, whether constitutive Stat3 signaling plays a role in the survival and growth of osteosarcomas, rhabdomyosarcomas, and soft-tissue sarcomas is
