Anti-Inflammatory Agents, Non-steroidal Anti-Inflammatory Agents, Non-steroidal Anti-Inflammatory Agents, Non-Steroidal (MeSH) - Anti-inflammatory agents that are not steroids. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions. They are used primarily in the treatment of chronic arthritic conditions and certain soft tissue disorders associated with pain and inflammation. They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidon…

Antineoplastic Agents Antineoplastic Agents Antineoplastic Agents - Substances that inhibit or prevent the proliferation of NEOPLASMS. (MeSH) Anticarcinogenic Agents - Agents that reduce the frequency or rate of spontaneous or induced tumors independently of the mechanism involved. They differ from antineoplastic agents in that they prevent neoplasms from forming. The anticarcinogenic substances can be divided into three categories. The first consists of compounds that prevent the formation of carcinogens from prec…

Chelating Agents Chelating Agents Chelating Agents - Organic chemicals that form two or more coordination bonds with a central metal ion. Heterocyclic rings are formed with the central metal atom as part of the ring. Some biological systems form metal chelates, e.g., the iron-binding porphyrin group of hemoglobin and the magnesium-binding chlorophyll of plants. (From Hawley's Condensed Chemical Dictionary, 12th ed) They are used chemically to remove ions from solutions, medicinally against microorganisms, to t…

Ionophores Ionophores Chemical agents that increase the permeability of biological or artificial lipid membranes to specific ions. Most ionophores are relatively small organic molecules that act as mobile carriers within membranes or coalesce to form ion permeable channels across membranes. Many are antibiotics, and many act as uncoupling agents by short-circuiting the proton gradient across mitochondrial membranes. ,

Neuroprotective agents Neuroprotective agents Drugs intended to prevent damage to the brain or spinal cord from ischemia, stroke, convulsions, or trauma. Some must be administered before the event, but others may be effective for some time after. They act by a variety of mechanisms, but often directly or indirectly minimize the damage produced by endogenous excitatory amino acids.

Oxidation-Reduction Oxidation-Reduction A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471). (
Plants Plants Multicellular, eukaryotic life forms of the kingdom Plantae. They are characterized by a mainly photosynthetic mode of nutrition; essentially unlimited growth at localized regions of cell divisions (MERISTEMS); cellulose within cells providing rigidity; the absence of organs of locomotion; absence of nervous and sensory systems; and an alteration of haploid and diploid generations. Year introduced: PYRETHRUM was heading 1963-1985 (
Protein synthesis inhibitors 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. ,
Purine Purine A series of heterocyclic compounds that are variously substituted in nature and are known also as purine bases. They include adenine and guanine, constituents of nucleic acids, as well as many alkaloids such as caffeine and theophylline. Uric acid is the metabolic end product of purine metabolism. , ,
Pyrimidine Pyrimidine A family of 6-membered heterocyclic compounds occurring in nature in a wide variety of forms. They include several nucleic acid constituents (cytosine, thymine and uracil) Name Pyrimidine Y MeSH 68011743 Molecular Weight 80.08796 g/mol Molecular Formula XLogP -0.3 , ,
