Russell-Jones theory for the dissociative volatilization process and a standard approach based on the Arrhenius model. The values of the parameters characterizing the thermal properties of alkanaminium hexachlorostannates, i.e. temperatures of the thermal effects, and the thermochemical and kinetic constants of thermolysis, depend on the number, length and structure of the alkyl substituent. The essential
摘要 热分析方法(DTA、TG 和 DTG)用于研究具有通式 [(CnH2n+1)pNH4-p]2SnCl6(其中 n = 1–4 和 p = 2–4)的无支链复合盐的热行为和其他几种环状和开链支链脂肪族链烷胺六氯锡酸盐。这些化合物的热解离通常可以使用等式来概括,其中 A 表示烷基(a = 0 和 s = 1 表示季铵盐,a = 1 和 s = 0 表示其他研究的化合物)。具有简单结构的衍生物的热解发生在一个步骤中并导致它们的完全挥发。其他化合物的分解,通常具有复杂的结构,伴随着副反应。实验 TG 曲线用于检查热解的热力学和动力学。热解离焓基于范特霍夫方程进行评估。导出的值与可用的文献数据一起用于确定盐的形成焓和晶格能。后者的数量也使用 Kapustinskii-Yatsimirskii 公式进行了检查。使用Jacobs 和Russell-Jones 解离挥发过程理论和基于Arrhenius

ECE-1 and NEP with IC50 values of 14 nM and 2 microM, respectively. Similarly, (S)-[[1-[(2-biphenyl-4-ylethyl)carbamoyl]-4-(2-fluorophenyl)but-3- yny l]amino]methyl]phosphonic acid (56), an arylacetylene amino phosphonate amide, had IC50's of 33 nM and 6.5 microM for ECE-1 and NEP, respectively. Slight modification of the aryl moiety was found to have dramatic effects on ECE-1/NEP selectivity. The 2-fluoro

The present invention relates to compounds of the formula I,
wherein R1, R2, R3, R4 and X have the meanings indicated in the claims. The compounds of formula I are valuable pharmacologically active compounds. They are highly potent and selective soluble epoxide hydrolase inhibitors and are suitable, for example, for the therapy and prophylaxis of renal failure, diabetic nephropathy, type 2 diabetes mellitus, cardiovascular diseases, inflammatory diseases or could show beneficial effects in pain, dyslipidemia, atherosclerosis wound healing and stroke. The invention furthermore relates to processes for the preparation of compounds of the formula I, their use, in particular as active ingredients in pharmaceuticals, and pharmaceutical preparations comprising them.
