Abstract

The focus of studies of diet/cancer interrelationships is shifting from the roles nutrients play to the chemopreventive actions of plant-derived, non-nutrient dietary constituents (indoles, coumarins, phthalides, organosulfur compounds, phytoestrogens, isothiocy-anates, bioflavonoids and protease inhibitors). Our interest in this aspect of diet/health relationships has roots in findings that products of plant mevalonate pathways both suppress hepatic mevalonate synthesis with a concomitant lowering of serum LDL cholesterol level and suppress the growth of chemically-initiated and transplanted tumors.1–4 Some of the more effective end products derived from the sequential mevalonate pathway intermediates, geranyl pyrophosphate, farnesyl pyrophosphate and geranylgeranyl pyrophosphate, are listed on Figure 1.1, 2 The pathway provides essential dietary components, specifically phylloquinone, β-carotene and a-tocopherol. The monoterpenes and sesquiterpenes have no nutritional impact. Never the less each of the products listed on Figure 1 has been shown to have an impact on HMG CoA reductase activity, blood cholesterol level and tumor cell proliferation.1–4
