Description

Pyrazoloacridine (NSC 366140), an intercalating agent with anti-cancer activity, inhibits the activity of topoisomerases 1 and 2. Pyrazoloacridine (NSC 366140) exhibits an IC50 of 1.25 μM in K562 myeloid leukemia cells for 24 h treatment[1][2].

In Vitro

Pyrazoloacridine (NSC 366140, PD 115934) exhibits IC50 values of 10.7 μM and 4.5 μM for oxic and hypoxic HCT-8 cells[1].
Pyrazoloacridine (NSC 366140, 2-4 μM) abolishes the catalytic activity of both topo I and topo II in vitro[2].
Pyrazoloacridine (NSC 366140) displays activity against cisplatin- and paclitaxel-resistant ovarian cancer[2].
Pyrazoloacridine (NSC 366140) has been shown to cause delayed DNA fragmentation in MCF-7 breast cancer cells[2].
Pyrazoloacridine (NSC 366140) induces apoptosis in P53-deficient Hep 3B human hepatoma cells[2].

Cell Cytotoxicity Assay[2]

Cell Line: K562 Myeloid Leukemia Cells.
Concentration: 0-500 μM.
Incubation Time: 1 h or 24 h.
Result: When K562 cells were incubated with PA for 1 h and then plated in soft agar, an IC50 of -50 μM was observed. In contrast, when cells were incubated for 24 h with PA, the IC50 was 1.25 μM.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
