In heterogeneous catalysis, the catalyst is in a different phase from the reactants. category: benzodioxans, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 2879-20-1, name is 1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)ethanone. In an article£¬Which mentioned a new discovery about 2879-20-1
N-(4-Substituted-thiazolyl)oxamic Acid Derivatives, a New Series of Potent, Orally Actve Antiallergy Agents
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.category: benzodioxans
