agreement with unrestrained molecular mechanics conformation searches. The ter-cyclopentane scaffold adopts an extended rigid conformation, with inter-ring torsion angles preferentially at 180°. These experiments demonstrate that conformational hypotheses developed in the course of designing ter-cyclopentane scaffolds for lipid A recognition are accurate, and furthermore provide support to the broader
明确定义的环烷烃低聚物包含一类相对未经研究的有机化合物,并且可能在开发生物相关分子的受体方面具有普遍用途。我们已经通过分子建模和核磁共振光谱研究了此类三环戊烷成员的溶液结构。我们发现,结合 NMR 衍生约束的构象搜索得出的分子集合与不受限制的分子力学构象搜索具有极好的定性一致性。三环戊烷支架采用扩展的刚性构象,环间扭转角优先为180°。这些实验表明,在设计用于脂质 A 识别的三环戊烷支架的过程中提出的构象假设是准确的,并进一步支持更广泛地使用此类化合物作为分子识别中的支架。(© Wiley-VCH Verlag GmbH & Co.
