Chemically, PCP is a member of the arylcyclohexylamine class, and pharmacologically, it is a dissociative anesthetic. [ 5][ 10][ 11] PCP works primarily as an NMDA receptor antagonist. [ 10] PCP is most commonly used in the United States. [ 12] While usage peaked in the US in the 1970s, [ 13] between 2005 and 2011 an increase in visits to ...
Cyclohexylamine is used as an intermediate in synthesis of other organic compounds. It is the precursor to sulfenamide -based reagents used as accelerators for vulcanization. The amine itself is an effective corrosion inhibitor. It has been used as a flushing aid in the printing ink industry. [ 5]
Polyketide synthase. Polyketide synthases ( PKSs) are a family of multi- domain enzymes or enzyme complexes that produce polyketides, a large class of secondary metabolites, in bacteria, fungi, plants, and a few animal lineages. The biosyntheses of polyketides share striking similarities with fatty acid biosynthesis. [ 1][ 2]
A linear biochemical pathway is a chain of enzyme-catalyzed reaction steps where the product of one reaction becomes the substrate for the next reaction. The molecules progress through the pathway sequentially from the starting substrate to the final product. Each step in the pathway is usually facilitated by a different specific enzyme that ...
A Furukawa-modified Simmons-Smith generated cyclopropane intermediate is formed in the synthesis of γ-keto esters from β-keto esters. The Simmons-Smith reagent binds first to the carbonyl group and subsequently to the α-carbon of the pseudo-enol that the first reaction forms. This second reagent forms the cyclopropyl intermediate which ...
Eticyclidine (PCE, CI-400) is a dissociative anesthetic drug with hallucinogenic effects. It is similar in effects to phencyclidine but is slightly more potent. PCE was developed by Parke-Davis in the 1970s and evaluated for anesthetic potential under the code name CI-400, [2] but research into PCE was not continued after the development of ketamine, a similar drug with more favourable ...
In biochemistry, a metabolic pathway is a linked series of chemical reactions occurring within a cell. The reactants, products, and intermediates of an enzymatic reaction are known as metabolites, which are modified by a sequence of chemical reactions catalyzed by enzymes. [ 1]: 26 In most cases of a metabolic pathway, the product of one enzyme ...
A biological pathway is a series of interactions among molecules in a cell that leads to a certain product or a change in a cell. Such a pathway can trigger the assembly of new molecules, such as a fat or protein. Pathways can also turn genes on and off, or spur a cell to move. [1] Some of the most common biological pathways are involved in ...
