生物活性

KR-39038 is an orally active and potent GRK5 (G protein-coupled receptor kinase 5) inhibitor, with an IC50 of 0.02 μM. KR-39038 significantly inhibits angiotensin II-induced cellular hypertrophy through suppression of HDAC5 pathway in neonatal cardiomyocytes. KR-39038 shows profound anti-hypertrophic effects and improved cardiac function. KR-39038 can be used for heart failure research[1].

体外研究
(In Vitro)

KR-39038 (0-1.0 μM, 24 h) significantly inhibits angiotensin II-induced cellular hypertrophy and HDAC5 phosphorylation in neonatal cardiomyocytes[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

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.
