NSC-19630

NSC-19630 (MIRA-1) is a cell-permeable inhibitor of Werner syndrome WRN helicase activity (IC50 = 20 uM) over its ATPase and exonuclease activities, but did not affect other DNA helicases [Bloom syndrome (BLM), Fanconi anemia group J (FANCJ), RECQ1, RecQ, UvrD, or DnaB). Exposure of human cells to NSC 19630 dramatically impairs growth and proliferation, induces apoptosis in a WRN-dependent manner, and results in elevated gamma-H2AX and proliferating cell nuclear antigen (PCNA) foci. NSC-19630 exposure leads to delayed S-phase progression, consistent with the accumulation of stalled replication forks, and to DNA damage in a WRN-dependent manner.

Small volumes of NSC-19630 biochemical vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
