Pleiotropy (drugs) can respond to them, because the endogenous ones are endocrine messengers. Pleiotropy (drugs) In pharmacology, pleiotropy includes all of a drug's actions other than those for which the agent was specifically developed. It may include adverse effects which are detrimental ones, but is often used to denote additional beneficial effects. For example, statins are HMG-CoA reductase inhibitors that primarily act by decreasing cholesterol synthesis, but which are believed to have other beneficial effects, including acting as antioxidants and stabilizing atherosclerotic plaques.

Biodiversity and drugs example, caffeine, methyl salicylate and quinine. Streptomycin, neomycin, and erythromycin are derived from tropical soil fungi. A lot of plant species are used in today's studies and have been exhaustively studied for their potential value as source of drugs. It is possible that some plant species may be a source of drugs against high blood pressure, AIDS or heart troubles. In China, Japan, India and Germany, there is a great deal of interest in and support for the search for new drugs from higher plants. Each species carries unique genetic material in its DNA and in its chemical factory responding
