실험 절차

Additionally, a sample of the compound of formula (1) was prepared in water to determine the approximate solubility of the compound in the absence of excipients (e.g., CAPTISOL®). A concentration of approximately 300 mg/mL was achieved, not accounting for the volume contribution of the compound. The pH of the sample was determined to be 2.8, which was adjusted to the target of 4.0 using 0.1 N NaOH. Upon pH adjustment, precipitation of a small amount of solid was observed. The clear solution was diluted in acetonitrile and analyzed by HPLC, resulting in an observed solution concentration of 268 mg/mL. A similar analysis was performed for the compound of formula (2). The compound of formula (2) has a solubility of approximately 10 mg/mL.
