Product Information
| Description: | C188 is a STAT3 inhibitor that inhibits IL-6-stimulated STAT3 phosphorylation and nuclear translocation in HepG2 cells by targeting STAT3 SH2 domain peptide-binding pocket. C188, in particular, was highly active in inducing apoptosis of the breast cancer cell line MB-MDA-468 in vitro (EC50= 0.7 μM). |
| Stability and Solubility Advice: | Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
