Cell Studies
Apigenin
(1 micromole = one-thousandth of a gram-molecule)
1. This study suggests that 60 micromoles of the flavonoids apigenin, quercetin, myricetin, and kaempferol induced cell death in leukaemic cells.

2. Dosages of apigenin in amounts (12.5 to 50 micromoles) may inhibit the growth of thyroid cancer cells.

ELLAGIC ACID
Animal Study
3. Rats were fed a diet comprised of 5 and 10% lyophilized black raspberries (LBRs) for 2 weeks before being exposed to a cancer inducing agent. This treatment lessened the proliferation of tumors. When LBRs were fed following the exposure to the carcinogen, proliferation of tumors was again inhibited, the number of tumors was reduced as was lesion development.

4. Ellagic acid (100 mg/kilogram body weight per day) and Vitamin E (100 mg/kilogram body weight per day) were found to have an anticarcinogenic effect against toxin exposure in mice.

MILK THISTLE/SILYMARIN
(ppm = parts per million)
5. Rats were fed a diet containing silymarin (100 and 500 ppm)) for 1 week before being exposed to carcinogens which decreased cancer cell proliferation and increased cancer cell death.
Carcinogenesis. 2002 May;23(5):787-94. (Animal Study)
Dietary silymarin suppresses 4-nitroquinoline 1-oxide-induced tongue carcinogenesis in male F344 rats.
Yanaida Y, Kohno H, Yoshida K, Hirose Y, Yamada Y, Mori H, Tanaka T.
Animal Study
6. Doses of silibinin (100 and 200 mg/kilogram body weight/day) could have cancer preventive effects on liver, lung, stomach, skin and small bowel tissue in mice.

Tissue distribution of silibinin, the major active constituent of silymarin, in mice and its association with enhancement of phase II enzymes: implications in cancer chemoprevention.
Zhao J, Agarwal R.
Animal Study
7. Doses of silymarin (3 mg, 6 mg and 12 mg), given prior to exposure to carcinogens resulted in fewer tumors, less proliferation of tumors and smaller tumor volume. Silymarin provided a significant level of protection from carcinogenics.
Cancer Res. 1999 Feb 1;59(3):622-32.
A flavonoid antioxidant, silymarin, affords exceptionally high protection against tumor promotion in the SENCAR mouse skin tumorigenesis model.

N-acetyl L-cysteine (NAC)
(1 micromole = one-thousandth of a gram-molecule)
Cell Study
8. Administration of N-acetylcysteine (30 micromoles) protected cells from injury when exposed to ionizing radiation.
Cancer Res. 2003 Jun 15;63(12):3413-7.
2-Deoxy-D-glucose-induced cytotoxicity and radiosensitization in tumor cells is mediated via disruptions in thiol metabolism.

Animal Study
9. Mice ingesting N-acetylcysteine (12.25 millimoles per kilogram body weight) were injected with malignant cells. Their survival time following injection was higher than the control group and there was less cancer cell proliferation and metastasis.
