β-Lactam Derivatives as Inhibitors of Human Cytomegalovirus Protease
摘要:
The development of novel monobactam inhibitors of HCMV protease incorporating a carbon side chain at C-4 and a urea function at N-1 is described. Substitution with small groups at the C-3 position of the beta-lactam ring gave an increase in enzymatic activity and in stability; however, a lack of selectivity against other serine proteases was noted. The use of both tri- and tetrasubstituted urea functionalities gave effective inhibitors of HCMV protease. Benzyl substitution of the urea moiety was beneficial, especially when strong electron-withdrawing groups where attached at the para position. Modest antiviral activity was found in a plaque reduction assay.

Recent efforts to identify treatments for chronic diabetic complications have resulted in the discovery of a novel series of highly potent and selective (2-arylcarbamoyl-phenoxy)-acetic acidaldosereductaseinhibitors. The compound class features a core template that utilizes an intramolecular hydrogen bond to position the key structural elements of the pharmacophore in a conformation, which promotes
最近鉴定慢性糖尿病并发症的治疗方法的努力导致发现了一系列新的高效和选择性的(2-芳基氨基甲酰基-苯氧基)乙酸醛糖还原酶抑制剂。化合物类别的特征是核心模板,该模板利用分子内氢键将药效基团的关键结构元件定位在构象中,从而促进了高结合亲和力。铅候选物,例如40,5-氟-2-(4-溴-2-氟-苄硫代氨基甲酰基)-苯氧基乙酸,抑制醛糖还原酶,IC(50)为30 nM,而对醛还原酶的活性低1100倍,是一种与活性醛解毒有关的酶。另外,实施例40在4天STZ诱导的糖尿病大鼠模型中以31mg / kg / d po的ED(50)降低了神经山梨糖醇水平。

An efficientsynthesis of an adrenoceptor antagonist has been developed and demonstrated in a pilot plant. A linear synthesis that relied on a catalytic reduction of a rather insoluble nitroaromatic proved to be a viable route. The active pharmaceutical ingredient (API) that contained an amidine functional group was generated from the amino-containing precursor by activation of dimethylacetamide (DMA)
