Published: June 2024

In this study, we report a novel per-6-substituted β-cyclodextrin () featuring seven phosphoramidate moieties as an innovative host for inclusion. This structurally well-defined host has remarkable water solubility and was isolated in pure form. Analytical techniques such as NMR and ITC were used to probe the molecular interactions with different drug molecules. Our investigations revealed that host can form 2:1 inclusion complexes with various drugs. Further studies showed that the inclusions of drugs by β-CD host () are mostly enthalpy driven, highlighting the potential roles played by the phosphoramidate functionalities of the host. Comparatively, a per-O2, O3-acetylated analog () of compound was also obtained, which also shows unusual water solubility but diminished inclusion capability.

The efficiency of kinase inhibiting cancer therapeutics is often limited by their poor solubility in water. PEGylation is one possible strategy to improve the solubility of the drug, however, means to cleave these after reaching the target is important to make use of the therapeutic effects of the native drug. Moreover, the length of the PEG chains will have an effect on the solubility and binding.

Multiphoton fluorescence microscopy (MFM), renowned for its noninvasiveness and high spatiotemporal resolution, is extensively applied in brain structure imaging in vivo. Three-photon fluorescence (3PF) imaging, excited at the NIR-III window, can penetrate the deepest mouse cerebrovascular. Evans blue, a substance known for its low toxicity, high water solubility, and resistance to metabolism, is frequently employed to assess blood-brain barrier (BBB) permeability.

The development of covalent drugs, particularly those utilizing Michael acceptors, has garnered significant attention in recent pharmaceutical research due to the ability of such molecules to irreversibly inhibit protein function. This study focusses on the synthesis and evaluation of ethynylsulfonamides, which are predicted to have superior covalent binding ability, metabolic stability, and water solubility compared to traditional amides. We developed a straightforward synthesis method for ethynylsulfonamides and comprehensively evaluated the covalent binding abilities of these compounds using NMR with various nucleophilic amino acids in different solvents.
