之前的分析表明,苯环是活性药物成分(API)中普遍存在的骨架。在这里,我们分析了FDA批准的小分子API中苯环的取代模式,直到2019年,并表明只有少数取代模式(1-; 1,2-; 1,4-;和1,2,4-)占主导地位,并且随着时间的推移,分布保持相对恒定。我们假设可用的合成方法和一些苯型取代模式的发生之间的连接,通过提供一个概述的合成方法,阐述现有的取代模式和那些创造新的取代模式,包括药物化学家青睐的前者。最后,我们计算了含有苯型的API的药物化学性质,这些API通常被从业者用作设计元素,包括“药物样”,形状,复杂性和相似性/多样性,并在合成的背景下讨论这些性质。
Previous analyses have revealed that benzenoid rings are prevalent scaffolds in active pharmaceutical ingredients (APIs). Here, we analyze the substitution patterns of benzenoid rings in small molecule APIs approved by the FDA through 2019 and show that only a few substitution patterns (1-; 1,2-; 1,4-; and 1,2,4-) prevail, and the distribution has remained relatively constant over time. We postulate the connection between available synthetic methods and the occurrence of a few benzenoid substitution patterns by providing an overview of synthetic methods that elaborate existing substitution patterns and those that create new substitution patterns, including those of the former that are favored by medicinal chemists. Finally, we calculated medicinal chemistry properties of benzenoid containing APIs that are often used by practitioners as design elements, including "druglikeness", shape, complexity, and similarity/diversity and discuss these properties in the context of synthesis.
