One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 13623-94-4, Name is 1,1-Bis(methylthio)-2-nitroethylene, formurla is C4H7NO2S2. In a document, author is Odzak, Renata, introducing its new discovery. Application In Synthesis of 1,1-Bis(methylthio)-2-nitroethylene.
3-Amidoquinuclidine derivatives: Synthesis and interaction with butyrylcholinesterase
Racemates as well as (R)- and (S)-enantiomers of 3-pivalamidoquinuclidine (PivQ) and 3-acetamidoquinuclidine (AcQ) were prepared. Their quaternary racemic and enantiomerically pure N-benzyl derivatives (BnlPivQ and BnlAcQ) were synthesized as well. The amides were tested as substrates and inhibitors of butyrylcholinesterase (BChE) from horse serum (EC 3.1.1.8). No hydrolysis was observed under the experimental conditions applied. On the contrary, inhibition of BChE by (R)- and (S)-enantiomers of N-benzylquinuclidinium amides of pivalic acid was observed. The (S)-BnlPivQ with K-i = 41.57 mu mol dm(-3) was 3-fold more potent inhibitor than the (R)-enantiomer. On the other hand, preliminary results indicated that both enantiomers of N-benzylquinuclidinum amides of acetic acid may possibly be inhibitors as well as activators depending on the concentrations of benzoylcholine (BzCh) used as a substrate of BChE.
