are defined herein. The present invention also relates to the discovery that compounds having Formula I are activators of caspases and inducers of apoptosis. The compounds of this invention may be used to induce cell death in a variety of clinical conditions in which uncontrolled growth and spread of abnormal cells occurs.
chemical transformation strategy using DNA-conjugated benzoyl hydrazine as a common versatile precursor in azole chemical expansion of DELs. DNA-compatible reactions deriving from the common benzoyl hydrazine precursor showed excellent functional group tolerance with exceptional efficiency in the synthesis of various azoles, including oxadiazoles, thiadiazoles, and triazoles, under mild reaction conditions
DNA 编码的组合化学文库 (DEL) 技术是一种结合遗传学和化学力量的方法,已成为药物发现的宝贵工具。骨骼多样性在 DEL 应用中起着至关重要的作用,并且在很大程度上依赖于新的 DNA 兼容化学反应。我们在此报告了一种系统发育化学转化策略,该策略使用 DNA 共轭苯甲酰肼作为 DEL 的唑类化学扩展中的通用前体。源自常见苯甲酰肼前体的 DNA 相容反应显示出优异的官能团耐受性,在温和的反应条件下合成各种唑类(包括恶二唑、噻二唑和三唑)时具有出色的效率。

N-Acylhydrazones have been described as responsive compounds to a wide variety of triggers that are able to induce reversible structural changes. These reversible constitutional, conformational or configurational changes caused by physical or chemical stimuli are useful tools in designing molecular switches. We report herein bis-N-acylhydrazones as new switchable-light emissive molecules triggered by light

describe herein the synthesis of new profluorescent nitroxides based on 2,5-disubstituted-1,3,4-oxadiazoles as fluorescent moieties and the 2,2,6,6-tetramethylpiperidine-N-oxyl radical (TEMPO) as paramagnetic probes. The synthesis and optical and electronic properties of the oxadiazole-based precursors of the profluorescent nitroxides, as well as the nitroxides and their reduced forms are also described. Physical
