Disease relevance of NSC43338

• In this respect, the strong cytotoxic effect of alpha-thujaplicin on murine P388 lymphocytic leukemia cell line should be emphasized, considering that it has recently been found to be low in toxicity to mice [1].
• Alpha-thujaplicin at 1.25 microg/ml inhibited cell growth of human stomach cancer KATO-IIl by 86%, and Ehrlich's ascites carcinoma by 87%, respectively [2].
• Gamma-thujaplicin and beta-dolabrin, the constituents of the wood of Thujopsis dolabrata Sieb. et Zucc. var. hondai showed strong in vitro cytotoxic effects against the human stomach cancer cell lines KATO-III and Ehrlich's ascites carcinoma [3].
• Secondly, beta-dolabrin, gamma-thujaplicin and 4-acetyltropolone had obvious growth-inhibitory effect on two kinds of Legionella sp. 4-Acetyltropolone especially had strong antibacterial activity toward Legionella pneumophila SG 1, and its MIC value was 3.1 microg/ml [4].
• Antibacterial activity of alpha-thujaplicin on Enterococcus faecalis IFO-12965 [minimum inhibitory concentration (MIC): 1.56 microg/ml] was higher than that of gentamicin (MIC: 6.25 microg/ml) used as a positive control [2].

High impact information on NSC43338

• At 24 h after treatment, alpha-thujaplicin at 0.63 microg/ml inhibited the cell growth of murine P388 lymphocytic leukemia by 78%, and its cytotoxic activity at a concentration higher than 0.63 microg/ml was as high as that of vincristine, used as a positive control [1].
• Among these three compounds, gamma-thujaplicin had the strongest cytotoxic activity on the growth of this tumor cell line in vitro [4].
• The acute toxicities [50% lethal dose (LD50) value: intraperitoneal injection, Van der Waedem] of gamma-thujaplicin and beta-dolabrin in mice were 277 mg/kg and 232 mg/kg, respectively [3].
• Inhibitory activity of alpha-thujaplicin on carboxypeptidase A [50% inhibitory concentration (IC50): 3.24 x 10(-5) M] was higher than that of 1,10-phenanthroline used as a positive control [2].
• The acute toxicity of alpha-thujaplicin [50% lethal dose (LD50) value: 256 mg/kg] in mice was as strong as those of beta-dolabrin (LD50 value: 232 mg/kg) and gamma-thujaplicin (LD50 value: 277 mg/kg) [2].

Gene context of NSC43338

• In particular, the phytogrowth-inhibitory activity of gamma-thujaplicin was strong and it completely inhibited the germination of this seed of Brassica campestris L. subsp. rapa Hook f. et Anders at the concentration of 30 ppm [5].

Analytical, diagnostic and therapeutic context of NSC43338

• At 48 h after treatment, gamma-thujaplicin and 4-acetyltropolone at 0.63 microg/ml inhibited cell growth of murine P388 lymphocytic leukemia by 85% and 65%, respectively [4].
