Factor Xa Inhibitors (20) • Endogenous factors and drugs that inhibit or block the activity of FACTOR XA. MeSH

Fat Emulsions, Intravenous (5) • Emulsions of fats or lipids used primarily in parenteral feeding. MeSH

Fat Substitutes (1) • Compounds used in food or in food preparation to replace dietary fats. They may be carbohydrate-, protein-, or fat-based. Fat substitutes are usually lower in calories but provide the same texture as fats. MeSH

Fatty Acid Synthesis Inhibitors (5) • Compounds that interfere with FATTY ACID SYNTHASE resulting in a reduction of FATTY ACIDS. This is a target mechanism in humans of some ANTINEOPLASTIC AGENTS and ANTI-OBESITY AGENTS and of some ANTI-INFECTIVE AGENTS which interfere with CELL WALL and CELL MEMBRANE formation. MeSH

Fertilizers (1) • Substances or mixtures that are added to the soil to supply nutrients or to make available nutrients already present in the soil, in order to increase plant growth and productivity. MeSH

Fetotoxins (0) see Teratogens

Fibrin Modulating Agents (44)

Fibrinolytic Agents (57) • Fibrinolysin or agents that convert plasminogen to FIBRINOLYSIN. MeSH

Filaricides (8) • Pharmacological agents destructive to nematodes in the superfamily Filarioidea. MeSH

Fireproofing Agents (0) see Flame Retardants

Fixatives (9) • Agents employed in the preparation of histologic or pathologic specimens for the purpose of maintaining the existing form and structure of all of the constituent elements. Great numbers of different agents are used; some are also decalcifying and hardening agents. They must quickly kill and coagulate living tissue. MeSH

Flame Retardants (4) • Materials applied to fabrics, bedding, furniture, plastics, etc. to retard their burning; many may leach out and cause allergies or other harm. MeSH

Flavoring Agents (28) • Substances added to foods and medicine to improve the quality of taste. MeSH

Fluorescent Dyes (162) • Agents that emit light after excitation by light. The wave length of the emitted light is usually longer than that of the incident light. Fluorochromes are substances that cause fluorescence in other substances, i.e., dyes used to mark or label other compounds with fluorescent tags. MeSH

Folic Acid Antagonists (37) • Inhibitors of the enzyme, dihydrofolate reductase (TETRAHYDROFOLATE DEHYDROGENASE), which converts dihydrofolate (FH2) to tetrahydrofolate (FH4). They are frequently used in cancer chemotherapy. (From AMA, Drug Evaluations Annual, 1994, p2033) MeSH

Folic Acid Metabolism Inhibitors (0) see Folic Acid Antagonists

Food Additives (53) • Substances which are of little or no nutritive value, but are used in the processing or storage of foods or animal feed, especially in the developed countries; includes ANTIOXIDANTS; FOOD PRESERVATIVES; FOOD COLORING AGENTS; FLAVORING AGENTS; ANTI-INFECTIVE AGENTS (both plain and LOCAL); VEHICLES; EXCIPIENTS and other similarly used substances. Many of the same substances are PHARMACEUTIC AIDS when added to pharmaceuticals rather than to foods. MeSH

Food Coloring Agents (6) • Natural or synthetic dyes used as coloring agents in processed foods. MeSH

Food Preservatives (10) • Substances capable of inhibiting, retarding or arresting the process of fermentation, acidification or other deterioration of foods. MeSH

Free Radical Scavengers (31) • Substances that influence the course of a chemical reaction by ready combination with free radicals. Among other effects, this combining activity protects pancreatic islets against damage by cytokines and prevents myocardial and pulmonary perfusion injuries. MeSH
