Research speed reading in 2021. The prevalence of solvent effects catalysis has motivated developing quantitative kinetic, and theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states. 7689-03-4, Name is Campathecin, belongs to thiazines compound, is a common compound. In a pantent, author is Karimian, Azam, once mentioned the new application about 7689-03-4, Recommanded Product: 7689-03-4.
Dipyrimido[4,5-b:5,4-e][1,4]thiazine: synthesis and their enzyme inhibitory activity assessment on soybean 15-lipoxygenase
A series of new derivatives of dipyrimido[4,5-b:5,4-e][1,4] thiazine were synthesized by treatment of 5-amino-6-methyl-2-morpholino-4-pyrimidinethiol (1) with 5-bromo-2,4-dichloro-6-methylpyrimidine (2) in the presence of triethylamine and ethanol and subsequently with various secondary amines in EtOH/DMF. The thioether derivative 3 and heterocyclization products 4a-f were characterized by elemental analysis and spectroscopic techniques. The 15-LO inhibitory activities of the new synthesized compounds were also evaluated. The results show that compound 4e has the best IC50 of 15-LO inhibition (IC50 = 14.4 A mu M) but when all the products were theoretically docked into 15-LO, the GOLD scores of compounds 4e and 4d are 43.67 and 43.39 respectively, which show the best results. We suggest that the hydrogen bond interaction between Ser489 of 15-LO and the nitrogen of piperazine ring of compound 4e appears to play major role in lipoxygenase inhibition.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 7689-03-4, in my other articles.
