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].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
