Biological Activity

Description

BQU57, a derivative of RBC8, is a selective GTPase Ral inhibitor relative to the GTPases Ras and RhoA.

Targets

GTPase Ral ^[1]

In vitro

In both the H2122 and H358 cell lines, BQU57 inhibits both RalA and RalB activation, and thus causes cell growth inhibition. ^[1]

In vivo

In mice bearing human lung H2122 tumors, BQU57 (50 mg/kg, i.p.) significantly inhibits activation of both RalA and RalB, and causes dose-dependent tumor growth inhibition. ^[1]

Protocol (from reference)

Cell Assay:^{^[1]}	Cell lines Human lung cancer lines, H2122, H358, H460 and Calu6 Concentrations ~10 μM Incubation Time 48 hours Method Growth inhibition on human lung cancer cells by the compounds are measured under anchorage-independent conditions in soft agar. Cells are seeded into 6-well plates (coated with a base layer made of 2.0 mL of 1% low-melting-point agarose) at 15,000 cells per well in 3.0 mL of 0.4% low-melting-point agarose containing various concentration of drug. Two to four weeks (depending on cell line) after incubation, cells are stained with 1.0 mg/mL Nitro Blue Tetrazolium and colonies are counted under a microscope. The IC50 values are defined as the concentration of drug that resulted in 50% reduction in colony number compared to DMSO treated control. After 48 hr, cells are subjected to the soft agar colony formation assay.
