Radicicol is an inhibitor of Hsp90 with an IC50 value < 1 μM, and leads to proteasomal degradation. Radicicol exhibits inhibition on PDK with IC50s of 230 μM (PDK1) and 400 μM (PDK3). Radicicol is an antifungal and antimalarial antibiotic, impairs mitochondrial replication by targeting P. falciparum topoisomerase VIB. Radicicol is also an inhibitor of fat mass and obesity-associated protein (FTO), with an IC50 value of 16.04 μM.

    In Vitro

    Radicicol (1 μM or 100 μM) inhibits the activities of Hsp90 and Topo VI by blocking ATP binding[1].
    ? Radicicol (100 μM; 10 min) binds to ATP-binding site in the C-terminal domain of PDK3 and prevents maturation of Hsp90 clients[1].
    ? Radicicol (0.25-18 μM; 48 h) inhibits P. falciparum?3D7 growth with an IC50 value of 8.563 μM, and (8 μM; 50 h) delays the schizont-to-ring transition[2].
    ? Radicicol (1.5 μM; 40 h) suppresses mitochondrial DNA replication without affecting nuclear and apicoplast genomes[2].
    ? Radicicol (0.001-5 μM; 72 h) induces myoblast differentiation with the myoblast toxicity concentration of 0.1 μM[5].

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

    In Vivo

    Radicicol (20 mg/kg or 60 mg/kg; i.p.; twice dosages; 1 h before and after) has renoprotection effect, and ameliorates renal ischemia reperfusion (I/R) injury and increases renal HSP70 mRNA and protein in renal injury mice[4].
    ? Radicicol (0.05 mg/20 g; s.c.; single dose) enhances the regeneration of skeletal muscle injured by crotoxin via decrease of NF-kB activation[5].

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

    Animal Model: Renal I/R injury model in mice[4]
    Dosage: 20 mg/kg or 60 mg/kg
    Administration: Intraperitoneal injection; twice dosages; 1 h before and just after bilateral renal ischemia reperfusion (I/R)
    Result: Showed renoprotection effect by inducing renal HSP70 expressing.
    Animal Model: Male C57B1/6 mice (3-month-old, 25±2 g)[5]
    Dosage: 0.05 mg/20 g
    Administration: Subcutaneous injection; single dose; immediately before CTX injury (~1 min); evaluated on day one or 10 after injection
    Result: Resulted heat shock protein induction and decreased NF-kB activation in muscle injured by crotoxin at days 10.
    Improved the size recovery of regenerating myofibers and decreased NF-kB activation.

    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.
