Drug partitioning in nuclear condensates There is increasing interest in the function of phase-separated biomolecular condensates in cells because of their distinct properties and expanding roles in important biological processes. Klein et al. considered the fate of small-molecule therapeutics in the context of nuclear condensates (see the Perspective by Viny and Levine). They show that certain antineoplastic drugs have physicochemical properties that cause them to concentrate preferentially in condensates, both in vitro and in cancer cells. This property influences drug activity, and protein mutations that alter condensate formation can lead to drug resistance. Optimizing condensate partitioning may be valuable in developing improved therapeutics. Science, this issue p. 1386; see also p. 1314 Phase-separated condensates in the cell nucleus concentrate small-molecule drugs, modulating their on-target activity and pharmacodynamics. The nucleus contains diverse phase-separated condensates that compartmentalize and concentrate biomolecules with distinct physicochemical properties. Here, we investigated whether condensates concentrate small-molecule cancer therapeutics such that their pharmacodynamic properties are altered. We found that antineoplastic drugs become concentrated in specific protein condensates in vitro and that this occurs through physicochemical properties independent of the drug target. This behavior was also observed in tumor cells, where drug partitioning influenced drug activity. Altering the properties of the condensate was found to affect the concentration and activity of drugs. These results suggest that selective partitioning and concentration of small molecules within condensates contributes to drug pharmacodynamics and that further understanding of this phenomenon may facilitate advances in disease therapy.

核凝聚物中癌症治疗剂的分配

核凝聚物中的药物分配人们对细胞中相分离生物分子凝聚物的功能越来越感兴趣，因为它们具有独特的性质以及在重要生物过程中不断扩大的作用。克莱因等人。考虑了核凝聚背景下小分子疗法的命运（参见 Viny 和 Levine 的观点）。他们表明，某些抗肿瘤药物具有物理化学特性，导致它们在体外和癌细胞中优先浓缩在冷凝物中。这种特性会影响药物活性，而改变冷凝物形成的蛋白质突变可能会导致耐药性。优化冷凝水分配对于开发改进的治疗方法可能很有价值。科学，本期第 14 页。 1386;另见 p. 1314 细胞核中的相分离凝聚物浓缩小分子药物，调节其靶向活性和药效学。细胞核含有不同的相分离凝聚物，可分隔和浓缩具有不同物理化学性质的生物分子。在这里，我们研究了冷凝物是否浓缩了小分子癌症治疗药物，从而改变了它们的药效学特性。我们发现抗肿瘤药物在体外浓缩在特定的蛋白质浓缩物中，并且这是通过与药物靶点无关的物理化学特性发生的。在肿瘤细胞中也观察到这种行为，其中药物分配影响药物活性。研究发现改变冷凝物的性质会影响药物的浓度和活性。这些结果表明，冷凝物中小分子的选择性分配和浓缩有助于药物药效学，并且进一步了解这种现象可能有助于疾病治疗的进步。
