Discovery and Optimization of a Novel Series of Dyrk1B Kinase Inhibitors To Explore a MEK Resistance Hypothesis
摘要:
Potent and selective inhibitors of Dyrk1B kinase were developed to explore the hypothesis, based on siRNA studies, that Dyrk1B may be a resistance mechanism in cells undergoing a stress response.

Described herein are silicon based conjugates capable of delivering one or more payload moieties to a target cell or tissue. Contemplated conjugates may include a silicon-heteroatom core, one or more optional catalytic moieties, a targeting moiety that permits accumulation of the conjugate within a target cell or tissue, one or more payload moieties (e.g., a therapeutic agent or imaging agent), and two or more non-interfering moieties covalently bound to the silicon-heteroatom core.

6-methyl-7-azaindole, and the parent 4-, 5-, 6-, and 7-azaindole systems (as anions in dimethylformamide) were alkylated with a variety of primary alkylating agents. The relative importance of charge, product development, and steric approach control in determining the alkylation pattern (pyrrole versus pyridine ring alkylation) are discussed within a framework of variable SN2 transition state structures
7-甲基-6-氮杂吲哚,7-乙酰氨基-4-氮杂吲哚,取代的4-氨基-,2-甲基和6-甲基-7-氮杂吲哚以及母体4-,5-,6-和7 -氮杂吲哚体系(作为二甲基甲酰胺中的阴离子)用各种伯烷基化剂烷基化。在可变的S N 2过渡态结构的框架内,讨论了电荷,产物发展和空间途径控制在确定烷基化模式(吡咯对吡啶环烷基化)中的相对重要性。边界轨道因素似乎相对微不足道。这些杂环系统的电荷分布,轨道和能量学是从头算起的分子轨道计算(STO-3G级)。在某些情况下,涉及缔合相邻基团和烷基化剂之间氢键的特定缔合对于确定烷基化模式很重要。

An etchant for copper includes an acid and one or more compounds selected from the group consisting of an aliphatic noncyclic compound, an aliphatic heterocyclic compound and a heteroaromatic compound. The aliphatic noncyclic compound is a saturated aliphatic noncyclic compound (A) including only two or more nitrogen atoms as heteroatoms, and 2 to 10 carbon atoms. The aliphatic heterocyclic compound is a compound (B) including a five-, six-, or seven-membered ring having one or more nitrogen atoms as one or more heteroatoms constituting the ring. The heteroaromatic compound is a compound (C) including a six-membered heteroaromatic ring having one or more nitrogen atoms as one or more heteroatoms constituting the ring.
