The synthesis and structure-activity relationships of a series of 6-phenyl-2-aminopyridines that potently and selectivelyinhibit the neuronal isoform of nitricoxidesynthase (nNOS) are described. Compound 14bi from this series exhibits potent in vivo activity in harmaline-induced cGMP formation in rat cerebellum, a functional model of nNOS inhibition, and in the PCP-induced hypermotility model in

We report a data-driven, physicalorganic approach to the development of new methionine-selective bioconjugation reagents with tunable adduct stabilities. Statistical modeling of structural features described by intrinsic physicalorganic parameters was applied to the development of a predictive model and to gain insight into features driving the stability of adducts formed from the chemoselective
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
