SU086

SU086 is a chalcone-derived HSP90 inhibitor. SU086 interacts with HSP90, reduces HSP90 protein levels, and suppresses glycolysis in prostate cancer cells. SU086 can be used in research related to advanced prostate cancer and castration-resistant prostate cancer (CRPC).

SU086 (1 μM; 24 or 48 h) reduces the protein level of HSP90 in C4-2 and DU145 cells; MG132 (HY-13259) (10 μM) partially reverses the SU086-induced downregulation of HSP90 ^[1].
SU086 (1 μM; 48 h) reduces the levels of 38 common proteins by more than 2-fold in C4-2 and DU145 cells, including HSP90, and enriches HSP90-interacting proteins and glycolysis-regulating proteins^[1].
SU086 (1 μM; 24 h) reduces glycolytic flux by approximately 50% and glycolytic capacity by 30%-50% in C4-2 and DU145 cells, while the OCR that reflects oxidative phosphorylation remains unchanged^[1].

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.
