Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics, 31618-90-3, Name is (Diethoxyphosphoryl)methyl 4-methylbenzenesulfonate, SMILES is O=S(C1=CC=C(C)C=C1)(OCP(OCC)(OCC)=O)=O, belongs to phthalazine compound. In a document, author is Berber, Nurcan, introduce the new discover, Safety of (Diethoxyphosphoryl)methyl 4-methylbenzenesulfonate.
A new series of phthalazine substituted urea and thiourea derivatives were synthesized, and their inhibitory effects on the activity of purified human carbonic anhydrases (hCAs I and II) were evaluated. 2H-Indazolo[2,1-b]phthalazine-trione derivative (1) was prepared with 4-nitrobenzaldehyde, dimedone, and phthalhydrazide in the presence of TFA in DMF, and nitro group was reduced to amine derivative (2) with SnCl2 center dot 2H(2)O. The compound was reacted with isocyanates and isothiocyanates to get the final products (3a-p). The results showed that all the synthesized compounds inhibited the CA isoenzymes activity. 3a (IC50 = 6.40 mu M for hCA I and 6.13 mu M for hCA II) has the most inhibitory effect. The synthesized compounds are very bulky to be able to bind near the zinc ion, and they much more probably bind as the coumarin derivatives.
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 31618-90-3 is helpful to your research. Safety of (Diethoxyphosphoryl)methyl 4-methylbenzenesulfonate.
