11F-CPT

11F-CPT is a Topoisomerase I inhibitor that stabilizes the TOP I-DNA cleavage complex. 11F-CPT inhibits TOP I-mediated DNA relaxation, induces DNA damage, and activates ATR-CHK1 signaling. 11F-CPT selectively inhibits proliferation and colony formation in pancreatic cancer cells, upregulates γ‑H2AX, and induces cell cycle arrest and apoptosis. 11F-CPT inhibits tumor growth in the PAN02 pancreatic cancer xenograft model and enhances the thermal stability of TOP I in cells. 11F-CPT can be used for research on pancreatic cancer.

Anti-cancerApoptosisCell Cycle RegulationOthers

Anti-cancer

11F-CPT (compound W3) (48 h) is highly cytotoxic in these cancer cell lines, with the lowest IC₅₀ values in UMUC3 and BxPC-3 cells (0.002 μM) and potent activity in A549 cells (0.262 μM)^[1].
11F-CPT (0.01-0.25 μM for BxPC-3; 0.1-2.5 μM for PANC-1; 24 h-14 days) reduces EdU incorporation and decreases colony formation in BxPC-3 and PANC-1 pancreatic cancer cells^[1].
11F-CPT (0.01 μM for BxPC-3; 0.1 μM for PANC-1; 48 h) increases the proportion of γ-H2AX-positive BxPC-3 and PANC-1 pancreatic cells^[1].
11F-CPT (0.5 μM for BxPC-3; 2.5 μM for PANC-1) inhibits the catalytic activity of TOP I in BxPC-3 and PANC-1 pancreatic cancer cells^[1].
11F-CPT enhances the thermal stability of TOP I in BxPC-3 pancreatic cancer cells and increases the DNA-bound TOP I^[1].
11F-CPT (0.1 μM) increases γ-H2AX and activates p-ATR/p-CHK1 signaling in BxPC-3 pancreatic cancer cells^[1].

Anti-cancer

Apoptosis

11F-CPT (0.01-0.25 μM for BxPC-3; 0.1-2.5 μM for PANC-1; 48 h) induces apoptosis in BxPC-3 and PANC-1 pancreatic cancer cells, increases Bax, Bad, and cleaved caspase-3, and decreases Bcl-2 and increases γ-H2AX protein levels^[1].

Anti-cancer

Cell Cycle Regulation

11F-CPT (0.01-0.25 μM for BxPC-3; 0.1-2.5 μM for PANC-1; 24 h) induces S phase accumulation in BxPC-3 and PANC-1 pancreatic cancer cells and causes G2/M phase arrest at higher concentrations; it also upregulates p53/p21 and CCNA1/CCNB1 and downregulates CCND1/CCNE1^[1].

Others

11F-CPT (0.25-1.5 μM; 30 min) inhibits TOP I-mediated DNA relaxation in a cell-free system^[1].

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.
