Spiramycin
A macrolide antibiotic produced by Streptomyces ambofaciens. The drug is effective against gram-positive aerobic pathogens, N. gonorrhoeae, and staphylococci. It is used to treat infections caused by bacteria and Toxoplasma gondii.
Year introduced: 1990
Coccidiostats
Agents useful in the treatment or prevention of COCCIDIOSIS in man or animals.
Year introduced: 1975
Anti-Bacterial Agents
Substances that inhibit the growth or reproduction of BACTERIA.
Year introduced: 2004(1963)
Polyketides
Natural compounds containing alternating carbonyl and methylene groups (beta-polyketones), bioenergenetically derived from repeated condensation of acetyl coenzyme A via malonyl coenzyme A, in a process similar to fatty acid synthesis.
Year introduced: 2012
Macrolides
A group of often glycosylated macrocyclic compounds formed by chain extension of multiple PROPIONATES cyclized into a large (typically 12, 14, or 16)-membered lactone. Macrolides belong to the POLYKETIDES class of natural products, and many members exhibit ANTIBIOTIC properties.
Year introduced: 1996
Organic Chemicals
A broad class of substances containing carbon and its derivatives. Many of these chemicals will frequently contain hydrogen with or without oxygen, nitrogen, sulfur, phosphorus, and other elements. They exist in either carbon chain or carbon ring form.
Year introduced: 1998
Leucomycins
An antibiotic complex produced by Streptomyces kitasatoensis. The complex consists of a mixture of at least eight biologically active components, A1 and A3 to A9. Leucomycins have both antibacterial and antimycoplasmal activities.
Year introduced: 1981
Lactones
Cyclic esters of hydroxy carboxylic acids, containing a 1-oxacycloalkan-2-one structure. Large cyclic lactones of over a dozen atoms are MACROLIDES.
Therapeutic Uses
Uses of chemicals which affect the course of conditions, diseases, syndromes or pathology to benefit the health of an individual.
Year introduced: 2004
Pharmacologic Actions
A broad category of chemical actions and uses that result in the prevention, treatment, cure or diagnosis of disease. Included here are drugs and chemicals that act by altering normal body functions, such as the REPRODUCTIVE CONTROL AGENTS and ANESTHETICS. Effects of chemicals on the environment are also included.
Year introduced: 2004(1999)
Chemical Actions and Uses
A group of pharmacologic activities, effects on living systems and the environment, and modes of employment of drugs and chemicals. They are broken into actions, which describe their effects, and uses, which describe how they are employed.
Year introduced: 1999
Antiprotozoal Agents
Substances that are destructive to protozoans.
Year introduced: 1967
Antiparasitic Agents
Drugs used to treat or prevent parasitic infections.
Anti-Infective Agents
Substances that prevent infectious agents or organisms from spreading or kill infectious agents in order to prevent the spread of infection.
