Clarithromycin
A semisynthetic macrolide antibiotic derived from ERYTHROMYCIN that is active against a variety of microorganisms. It can inhibit PROTEIN SYNTHESIS in BACTERIA by reversibly binding to the 50S ribosomal subunits. This inhibits the translocation of aminoacyl transfer-RNA and prevents peptide chain elongation.
Year introduced: 1993
Cytochrome P-450 CYP3A Inhibitors
Drugs and compounds which inhibit or antagonize the biosynthesis or actions of CYTOCHROME P-450 CYP3A.
Year introduced: 2015
Protein Synthesis Inhibitors
Compounds which inhibit the synthesis of proteins. They are usually ANTI-BACTERIAL AGENTS or toxins. Mechanism of the action of inhibition includes the interruption of peptide-chain elongation, the blocking the A site of ribosomes, the misreading of the genetic code or the prevention of the attachment of oligosaccharide side chains to glycoproteins.
Year introduced: 1988
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
Lactones
Cyclic esters of hydroxy carboxylic acids, containing a 1-oxacycloalkan-2-one structure. Large cyclic lactones of over a dozen atoms are MACROLIDES.
Erythromycin
A bacteriostatic antibiotic macrolide produced by Streptomyces erythreus. Erythromycin A is considered its major active component. In sensitive organisms, it inhibits protein synthesis by binding to 50S ribosomal subunits. This binding process inhibits peptidyl transferase activity and interferes with translocation of amino acids during translation and assembly of proteins.
Cytochrome P-450 Enzyme Inhibitors
Drugs and compounds which inhibit or antagonize the biosynthesis or actions of CYTOCHROME P-450 ENZYMES.
Metabolic Side Effects of Drugs and Substances
Specific effects of drugs and substances on metabolic pathways such as those occurring through the CYTOCHROME P-450 ENZYME SYSTEM. These include effects that often result in DRUG INTERACTIONS; FOOD-DRUG INTERACTIONS; and HERB-DRUG INTERACTIONS.
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
Molecular Mechanisms of Pharmacological Action
Pharmacological activities at the molecular level of DRUGS and other exogenous compounds that are used to treat DISEASES and affect normal BIOCHEMISTRY.
Year introduced: 2008(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
Enzyme Inhibitors
Compounds or agents that combine with an enzyme in such a manner as to prevent the normal substrate-enzyme combination and the catalytic reaction.
Year introduced: 1975(1964)
Anti-Infective Agents
Substances that prevent infectious agents or organisms from spreading or kill infectious agents in order to prevent the spread of infection.
