Tubulosine

Tubulosine is an alkaloid. Tubulosine can be isolated from Pogonopus tubulosus (DC.) Schumann. Tubulosine is an ATP-competitive, selective JAK3 inhibitor with an IC₅₀ value of 9.9 nM. Tubulosine also inhibits the kinase activities of other JAK family members, the extent of inhibition is less than that of JAK3, with IC₅₀ values of 69.5, 84.9 and 76.3 nM for JAK1, JAK2 and TYK2, respectively. Tubulosine selectively inhibits JAK3 signalling by binding to the ATP-binding site of the kinase of JAK3. Tubulosine induces apoptotic and necrotic/autophagic cell death. Tubulosine inhibits the process of peptide chain elongation by eukaryotic polysomes by, specifically preventing the elongation-factor-2-dependent step of translocation. Tubulosine exhibits anticancer activity in breast cancer cells.

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.
