β-Cylcodextrin
(purity >97%), γ-cylcodextrin
(purity >98%), 1-adamantane carboxylic acid (purity >99%), and
dimethyl
sulfoxide (DMSO) (purity of >99.9%) were purchased from Sigma-Aldrich.
The solubilities of β-cylcodextrin and γ-cylcodextrin
in water at 25 °C are 18.5 and 232 g/L, respectively,39 (link) while the solubility of 1-adamantane carboxylic
acid in buffer was about 0.75 g/L. We evaluated the latter by sound
velocity measurements as the value of sound velocity is very sensitive
to both aggregation and solute concentration.40 (link) All samples were prepared with solute concentrations below their
solubility values. Water was purified using a PURELAB Option-Q unit
(ELGA LabWater). D2O and deuterated dimethyl sulfoxide
(DMSO-d6) were purchased from Euriso-Top
(Saint-Aubin, France).

1H NMR spectra were recorded at 25 °C or 80 °C using a Bruker AVANCE III HD spectrometer operating at 400.13 MHz (1H). 1H NMR spectra were recorded by applying a 90° tip angle for the excitation pulse, and a 10 s recycle delay for accurate integration of the proton signals. Deuterium oxide (D2O) and deuterated dimethylsulfoxide (DMSO-d6) were obtained from Euriso-top (Saint-Aubin, France). Chemical shifts (δ in ppm) are given relative to external tetramethylsilane (TMS = 0 ppm) and calibration was performed using the signal of the residual protons of the solvent as a secondary reference. All NMR spectra were analyzed with Topspin 3.3.6 software from Bruker AXS.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
