SMD-1087

SMD-1087 is a VHL-recruiting SMARCA2 PROTAC degrader with a DC₅₀ of 8 nM. SMD-1087 induces ubiquitination and degradation of SMARCA2 via the proteasome pathway. SMD-1087 reduces PBRM1 protein levels, inhibits the growth of SMARCA4-deficient cancer cells, and suppresses tumor growth in mouse xenograft models. SMD-1087 can be used for research on SMARCA4-deficient human cancers, including lung cancer and melanoma.

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.
