Chemical engineers work across a number of sectors, processes differ within each of these areas, but chemistry and chemical engineering roles are found throughout, creation and manufacturing process of chemical products and materials. Application In Synthesis of 4-Bromo-2-fluoro-6-nitrotoluene, 502496-34-6, Name is 4-Bromo-2-fluoro-6-nitrotoluene, SMILES is CC1=C([N+]([O-])=O)C=C(Br)C=C1F, in an article , author is Berber, Nurcan, once mentioned of 502496-34-6.
A new series of phthalazine substituted beta-lactam derivatives were synthesized and their inhibitory effects on the activity of purified human carbonic anhydrase (hCA I and II) were evaluated. 2H-Indazolo[2,1-b]phthalazine-trione derivative was prepared with 4-nitrobenzaldehyde, dimedone, and phthalhydrazide in the presence of TFA in DMF, and the nitro group was reduced to 13-(4-aminophenyl)-3,3-dimethyl-3,4-dihydro-2H-indazolo[1,2-b]phthalazine-1,6,11(13H)-trione with SnCl2 center dot 2H(2)O. The reduced compound was reacted with different aromatic aldehydes, and phthalazine substituted imines were synthesized. The imine compounds undergo (2+2) cycloaddition reactions with ketenes to produce 2H-indazolo[2,1-b]phthalazine-trione substituted beta-lactam derivatives. The beta-lactam compounds were tested as inhibitors of the CA isoenzyme activity. The results showed that all the synthesized compounds inhibited the CA isoenzyme activity. 1-(4-(3,3-dimethyl-1,6,11-trioxo-2,3,4,6,11,13-hexahydro-1H-indazolo[1,2b]phthalazin-13-yl)phenyl)-2-oxo-4-p-tolylazetidin-3-yl acetate (IC50 = 6.97 A mu M for hCA I and 8.48 A mu M for hCA II) had the most inhibitory effect.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 502496-34-6. SDS of cas: 502496-34-6.
