chemical diversity with the hypothesis that chemical diversity will lead to diverse biological activities. We took a systematic approach to DOS to develop a focused library of reduced flavones from γ-pyrones with diversity of appendage, stereochemistry, and chemical properties to determine which features of small molecules are most predictive of biological performance diversity. The effects of these systematic
面向多样性的合成(DOS)历史上一直专注于具有相当大的化学多样性的小分子集合的开发,其假设是化学多样性将导致多种生物活性。我们对DOS采取了系统化的方法,从γ-吡喃酮中开发了具有还原性的黄酮类化合物的重点文库,该文库具有附肢,立体化学和化学性质的多样性,以确定小分子的哪些特征最能预测生物性能的多样性。这些变化对生物多样性的影响是通过细胞涂漆和细胞毒性试验确定的,以比较多种评估方法的结果。我们观察到更大比例的sp3杂化原子(fsp3)并不总能增强生物多样性,立体化学和附属物多样性都有助于生物多样性,并且吡喃酮类化合物的亲脂性与生物多样性相关。这些结果将有助于开发一种通用算法,以预测在合成DOS文库时应考虑哪些化学特征,以创建生物学性能多样的小分子集合,以进行探针和药物发现。
