bacterial mutagenicity in the Amestest using TA97a Salmonella strain, and subsequent study demonstrated that this mutagenicity was pervasive throughout the series. Identification of intercalation as a likely mechanism for the mutagenicity-enabled modification of the core scaffold. Implementation of a DNA binding assay as a prescreen and models in DNA allowed resolution of the mutagenicity risk, affording
描述了开发一系列具有良好药物样特性的高促动素选择性脾酪氨酸激酶(Syk)抑制剂。通过X射线晶体学分析,以及对选定化学空间内核心的系统调查(以配体结合效率为重点),发现了早期的铅。通过调节包括log D,PSA和p K a在内的物理化学性质来指导初始化学型中固有的hERG离子通道活性的减弱。PSA被证明对预期的化合物设计最有效。使用TA97a沙门氏菌的Ames试验进一步分析了先进化合物的细菌致突变性菌株,随后的研究表明,这种诱变性在整个系列中普遍存在。插入的鉴定是核心支架诱变启用修饰的可能机制。将DNA结合测定作为DNA的预筛选和模型,可以解决诱变风险,为分子提供了有利的效价,选择性,药代动力学和脱靶特性。

A convenient approach to 3-pyridinols and 5-pyrimidinols via a two-step Cu-catalyzed benzyloxylation/catalytic hydrogenation sequence is presented. The corresponding 3-pyridinamines and 5-pyrimidinamines can be prepared in an analogous sequence utilizing benzylamine in lieu of benzyl alcohol. The radical-scavenging ability of these derivatives are preliminarily explored and reveal that the increased acidities of the pyridinols and pyrimidinols render them susceptible to more significant kinetic solvent effects when compared to phenols.
