Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 143-66-8, Name is Sodium tetraphenylborate, SMILES is C1([B-](C2=CC=CC=C2)(C3=CC=CC=C3)C4=CC=CC=C4)=CC=CC=C1.[Na+], belongs to phthalazine compound. In a document, author is Munin, Javier, introduce the new discover, Formula: C24H20BNa.
Synthesis and vasorelaxant and antiplatelet activities of a new series of (4-Benzylphthalazin-1-ylamino)alcohol derivatives
A new series of phthalazine derivatives was synthesized by reaction of phthalic anhydride and different substituted phenylacetic acids to yield the benzyliden-3H-isobenzofuran-1-one intermediates 2a-d. Treatment of them with hydrazine afforded 4-benzyl-2H-phthalazin-1-one derivatives 3a-d, which were substituted with the corresponding aminoalkylalcohol to obtain the (4-benzylphthalazin-1-ylamino)alcohol derivatives 4a-h. In general, these phthalazine derivatives relaxed the contractions produced by phenylephrine both in intact or endothelium-denuded aortic rings. In addition, platelet aggregation induced by thrombin was also inhibited by compounds 4c and 4g.
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 143-66-8 is helpful to your research. Formula: C24H20BNa.
