生物活性

SNX-7081 is an Hsp90 inhibitor with Ki and IC50 values of 26 nM and 44 nM, respectively. SNX-7081 blocks the nuclear translocation of NF-κB, inhibits the production of pro-inflammatory cytokines, attenuates the ERK/JNK and PDGF signaling pathways, and suppresses LPS (HY-D1056)-induced nitric oxide production. SNX-7081 inhibits DNA repair, induces G2/M cell cycle arrest, and triggers apoptosis via downregulation of MYC/nucleolin and activation of Fas. SNX-7081 can be used in research related to rheumatoid arthritis and cancer[1][2][3].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
