Research speed reading in 2021. The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic. Formula: C10H10O3, In a article, mentioned the application of 2879-20-1, Name is 1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)ethanone, molecular formula is C10H10O3
A series of N-(4-substituted-thiazolyl)oxamic acid derivatives were synthesized and tested for antiallergy activity in the rat PCA model.These compounds were conveniently prepared by treatment of the appropriate acetophenone with thiourea and iodine or by reaction of the chloroacetylbenzene with thiourea to give the corresponding aminothiazoles; subsequent condensation with ethyloxalyl chloride gave the thiazolyloxamates.Many of the analogues showed a 50percent inhibition at <2 mg/kg po or <0.4 mg/kg iv and were significantly more potent than disodium cromoglycate, which in the rat PCA mode l is orally inactive and gives a 50percent inhibition at 1.2 mg/kg iv.Hydrolysis of the oxamates generally resulted in enhanced activities, while substitution of the phenyl ring with a variety of substituents (e.g.,4-F, 4-OEt, and 4-NHCOCH3) did not significantly enhance the activity of the unsubstituted phenyl derivative.One of the ethanolamine salts, N-<4-(1,4-benzodioxan-6-yl)-2-thiazolyl>oxamic acid ethanolamine salt (61, PRH-836-EA), has been selected for further pharmacological evaluation.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 2879-20-1, help many people in the next few years.Formula: C10H10O3
