Abstract

Cocrystals are of tremendous significance for the pharmaceutical industry, due to their favorable properties when compared to their salt analogs. The ΔpKa rule, commonly used in the identification of a cocrystal, meets shortcomings in the 0 ΔpKa 3 range, where salts and cocrystals ought to emerge. In this project, we probed the salt vs. cocrystal nature, using the strength of hydrogen bondings through the local mode analysis, in the case example of the product formed between thiobendazole and fumaric acid. Moreover, we employed a topological analysis of the electronic density to quantify the covalency of such interactions.

噻苯达唑:富马酸作为盐共晶连续体的案例研究:局部振动模式的视角
由于与盐类似物相比,共晶具有良好的性能,因此对制药工业具有巨大的意义。通常用于识别共晶的ΔpKa规则在0≤ΔpKa≤3范围内存在缺点,此时应该出现盐和共晶。在这个项目中,我们以硫苯达唑和富马酸之间形成的产物为例,通过局部模式分析,利用氢键的强度来探讨盐与共晶的性质。此外,我们采用电子密度的拓扑分析来量化这种相互作用的共价。

期刊介绍: Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage. Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
