Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 156-83-2, Name is 6-Chloropyrimidine-2,4-diamine, SMILES is NC1=CC(Cl)=NC(N)=N1, belongs to pyrimidines compound. In a document, author is Perez-Sanchez, Horacio, introduce the new discover, HPLC of Formula: C4H5ClN4.
Combined Structure and Ligand-Based Design of Selective Acetylcholinesterase Inhibitors
Acetylcholinesterase is a prime target for therapeutic intervention in Alzheimer’s disease. Acetylcholinesterase inhibitors (ACKEIs) are used to improve cognitive abilities, playing therefore an important role in disease management. Drug repurposing screening has been performed on a corporate chemical library containing 11 353 compounds using a target fishing approach comprising three-dimensional (3D) shape similarity and pharmacophore modeling against an approved drug database, Drugbank. This initial screening identified 108 hits. Among them, eight molecules showed structural similarity to the known ACKEI drug, pyridostigmine. Further structure-based screening using a pharmacophore-guided restoring method identifies one more potential hit. Experimental evaluations of the identified hits sieve out a highly selective AChEI scaffold. Further lead optimization using a substructure search approach identifies 24 new potential hits. Three of the 24 compounds (compounds 10b, 10h, and 10i) based on a 6-(2-(pyrrolidin-1-yl)pyrimidin-4-yl)-thiazolo[3,2-alpha]pyrimidine scaffold showed highly promising AChE inhibition ability with IC50 values of 13.10 +/- 0.53, 16.02 +/- 0.46, and 6.22 +/- 0.54 mu M, respectively. Moreover, these compounds are highly selective toward AChE. Compound 10i shows AChE inhibitory activity similar to a known Food and Drug Administration (FDA)-approved drug, galantamine, but with even better selectivity. Interaction analysis reveals that hydrophobic and hydrogen-bonding interactions are the primary driving forces responsible for the observed high affinity of the compound with AChE.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 156-83-2 is helpful to your research. HPLC of Formula: C4H5ClN4.
