  • ester
  • Preferential binding to nAChR in the absence of agonist is also seen for N , N -DEAE and N , N -diethylaminopropyl esters, both binding with 10-fold higher affinity in the absence of agonist than in the presence, and for the 4-ethoxybenzoic acid ester of N , N -diethylaminoethanol, but not for the 4-amino benzoate ester (procaine).

  • amino
  • Carboxylic acids produce mixed anhydrides of diphenylacetic acid, which can be used to activate protected amino acids for peptide linkage. (wikipedia.org)
  • 1 In fact, the essential amino acid tryptophan and the neurotransmitter serotonin contain the indole moiety in their structure. (rsc.org)
  • Each subunit has a common primary structure motif: a hydrophilic, extracellular N-terminal half containing amino acids of the agonist-binding sites, followed by three hydrophobic membrane spanning segments (M1-M3), a cytoplasmic domain, a fourth transmembrane segment (M4), and short extracellular C-terminal tail.

  • indole
  • The catalytic system based on the combination of Co(acac) 3 and 1,1,1-tris(diphenylphosphinomethyl)-ethane (Triphos, L1 ), in the presence of Al(OTf) 3 as co-catalyst, is able to perform the reductive alkylation of 2-methyl-1 H -indole with a wide range of carboxylic acids. (rsc.org)
  • acetone
  • The less soluble ( S )-( − ) diastereomer ( 1 ) is isolated in several crops by crystallization from 1.2 volumes of reagent-grade acetone at −20°C. After the first crop has been collected, 3 drops of concd hydrochloric acid is added to the acetone mother liquor to effect equilibration of the sulfinate diastereomers. (orgsyn.org)
  • mixture
  • It will not be discussed here how the phenylmalonic acid is formed, but in this connection it may be pointed out that phenylmalonic acid is also formed in the reaction of benzylsodium with carbon dioxide Tetraphenylmethane is also cleaved by potassium - actually more rapidly and more fully than 111, but the mixture of acids obtained after carbonation has a more complicated composition.

  • trade names Amidalgon, Spasmoxal) is an opioid analgesic which is a diphenylacetic acid derivative, related to other open-chain opioid drugs such as dextropropoxyphene, levacetylmethadol (LAAM), lefetamine and dimenoxadol. (wikipedia.org)
  • available
  • This new protocol enables the direct functionalization of indoles with readily available and stable carboxylic acids using a non-precious metal based catalyst and hydrogen as reductant. (rsc.org)
