Biological Activity

Description

2-Methoxy-1,4-naphthoquinone, isolated from the leaves of Impatiens glandulifera, specifically suppressed the expression of PKC βI, δ, and ζ in a concentration-dependent manner in Raji cells.

Targets

PKCβ1 ^[1]

PKCδ ^[1]

PKCζ ^[1]

In vitro

2-Methoxy-1,4-naphthoquinone (MNQ) exhibits antifungal, antimicrobial activities and showed strong killing effect on K562, HL-60, Raji, MCF-7, H-23, IMR-32, LA-174-T, HSC-2, and SK-MEL-28. MNQ is able to trigger the intrinsic apoptotic pathway in K562 cells, as well as causing p53-dependent cell cycle arrest in the p53-wild type cell line. MNQ inhibits the TCF/β-catenin (TOP) transcriptional activity at IC50 2.9 μM, while it decreases the transcriptional activity of FOP (mutated TCF-binding site)-transfected cell. MNQ exerts an anti-metastatic effect against MDA-MB-231 cells. MNQ has remarkable selectivity towards PKCβI and ζ suppression. MNQ suppresses PKCδ moderately, where MNQ suppresses half of the PKCδ expression at the concentration of 10 μM. MNQ does not suppress PKC βII^[1]. MNQ is able to inhibit the invasion and migration characteristics of a highly metastatic MDA-MB-231 cancer cell line^[2].

Protocol (from reference)

Cell Assay:^{^[1]}	Cell lines Raji cells Concentrations -- Incubation Time 48 h Method 5×10⁵ Raji cells are incubated in 1 mL of RPMI 1640 medium (supplemented with 10% FBS) containing 0.05 μM PMA, 3 mM SnB and test substance (MNQ or DMSO as the vehicle control) at 37 °C under 5% CO2 for 48 hours. Genistein is used as the standard drug. The cells are then harvested, washed with PBS and fixed onto Teflon-coated slides.
