[求助] 翻译一段(药物化学)

A widely used method to judge compounds for drug discovery
is the “rule of 5” (RO5) (6), which predicts poor absorption or
permeation for compounds that deviate from property-value
constraints: H-bond donors (Hd) and acceptors (Ha), molecular
weight (MW), and calculated partition coefficients (cLogP).
Recent studies have attempted to refine such rules (7–9) and
extend them to other goals (10–13), such as making leads or
probes. Such property filters have been debated and reviewed
(14–16), and their long-term impact on pharmaceutical research
is starting to be analyzed (17, 18). Importantly, exceptions to
these rules, including natural products (19–21), are well-noted
and suggest that previously undescribed types of chemistry might
access property distributions acceptable for certain goals despite
nonadherence to established rules.

得到广泛的用来鉴定药物化合物的方法是“RO5”规则,这种方法预测化合物的低吸附和低渗透会与属性值形成一定的偏差:氢键供体(Hd)和受体(Ha),分子量(Mw)以及计算出的分割系数(cLogP).最近的研究旨在进一步改进该规则并尽量使其能应用于其他方面,比如领导决策或调查。这一系列的特性都得到了讨论和重视,并且它们在制药上长期的影响也得到分析。更重要的是,除了这些规则,包括那些之前没被化学描述的也不会形成规则的天然产物,现也已得到充分的重视。
