BACKGROUND Thymoquinone is an active ingredient isolated from Nigella sativa (Black Seed). This study aimed to evaluate the in vitro and in vivo anti-leukemic effects of thymoquinone on WEHI-3 cells. METHODOLOGY/PRINCIPAL FINDINGS The cytotoxic effect of thymoquinone was assessed using an MTT assay, while the inhibitory effect of thymoquinone on murine WEHI-3 cell growth was due to the induct...
Many species belonging to the Scrophularia genus have been used since ancient times as folk remedies for many medical conditions such as scrofulas, scabies, tumors, eczema, psoriasis, inflammations. The aim of this study was to characterize the matrix metalloproteinases (MMPs) inhibitor compounds of the Scrophularia striata extract by bio-guide fractionation. The aerial parts of S. striata were...

PURPOSE Gypenosides (Gyp), found in Gynostemma pentaphyllum Makino, have been used as folk medicine for centuries and have exhibited diverse pharmacological effects, including antileukemia effects in vitro and in vivo. In the present study, Gyp were used to examine effects on cell viability, cell cycle, and induction of apoptosis in vitro. They were administered in the diet to mice injected wit...
The aim of this study was to explore the antitumor effect of Gan-Lu-Yin (GLY), a traditional Chinese herbal formula, on leukemia. Ethanolic extract of GLY was applied to evaluate its regulatory mechanisms in proliferation, migration, and differentiation of WEHI-3 leukemic cells as well as antitumor effect on BALB/c mice model. The results showed that GLY markedly reduced cell proliferation and ...
Leukocyte trafficking involves specific recognition between P-selectin and L-selectin and PSGL-1 containing core 2-based O-glycans expressing sialyl Lewis x (SLe(x)) antigen. However, the structural identity of the glycan component(s) displayed by murine neutrophil PSGL-1 that contributes to its P-selectin counter-receptor activity has been uncertain, since these cells express little if any SLe...
Curcumin (1, 7-bis(4-hydroxy-3-methoxyphenyl)-1,6-heptadiene-3,5- dione), a natural polyphenol product of the plant Curcuma longa, exhibited potent inhibitory activities against proliferation, induced cell cycle arrest and exhibited the induction of apoptosis in several tumor cell lines. In our previous studies, we have shown that curcumin induced cell cycle arrest and apoptosis on human leukem...
A series of 2,3,4,9-tetrahydrofuro[2,3-b]quinolin-3,4-dione and ethyl 2-(substituted aniline) -4-oxo-4,5-dihydrofuran-3-carboxylate were synthesized and evaluated for cytotoxicity on murine leukemia WEHI-3 cells. The cytotoxic effects of most compounds tested were dose-dependent and the structure-activity relationships indicated that N-substituted benzyl derivatives displayed a stronger inhibit...
WEHI-3B/NOVO is a cloned murine leukemia cell line selected for resistance to novobiocin that is cross-resistant to the cytotoxic action of etoposide (VP-16) and to a lesser extent to a variety of other topoisomerase II (topo ID-reactive drugs. We have reported previously (Cancer Res. 52: 2782-2790, 1992) that WEHI-3B/NOVO cells exhibit a pronounced de crease in VP-16 induced DNA-topo II cross-...
