Introduction:
Since disulfiram’s (DS) approval as an anti-alcoholism drug, extensive investigations have been carried out to explore other biomedical and pharmacological effects. In the past two decades, comprehensive anticancer mechanisms of action of DS were proposed and many molecular biological targets were identified, but the preliminary data from clinical trials show unsatisfactory results, not supporting the promising preclinical data. The deviation could be attributed to the drug`s poor solubility, instability, low bioavailability, rapid, unwanted metabolism, and poor delivery efficiency to tumor tissue, suggesting that the repositioning needs to be reached from both clinical and technological perspectives.
Aim:
The aim is to pave the path of DS anticancer repositioning with pharmaceutical technology tools by encapsulating the drug in cyclodextrin (CD) inclusion complexes to increase the solubility and stability, and promote the development of non-invasively administrable pharmaceutical forms.
Methods:
For the solubility and stability enhancement of the BCSII class drug (Sigma Aldrich), CD inclusion complexes were studied. Native (α-, β-, γ-CD) and pharmaceutical grade CD derivatives [hydroxypropyl (HP-β-CD), randomly methylated (RM-β-CD) and sulfobutylether sodium salt (SBE-β-CD)] (CycloLab) were selected. Solubility study and solid-state characterization of the inclusion complexes were assessed to determine the suitable formulation.
Results:
DS could play an adjuvant role in cancer therapy, enhancing the standard management protocol by radiotherapy and chemo-sensitizing effect and suppressing the tumor mass, thus inhibiting the cancer progression. The clinical translation of this adjuvant drug into cancer therapy can only be achieved with optimized drug delivery systems that overcome the poor bioavailability and low tumor-mass targeting efficacy. The solubility of DS was significantly increased by the CD derivates, and inclusion complex formation was achieved with CD derivatives, serving for a value-added pharmaceutical formulation of repurposed DS.
Conclusions:
The technological development strategy to encapsulate DS via CDs and to develop parenteral formulations with favorable pharmacokinetic profiles shows promise for the effective application of DS, ensuring drug solubility, stability, and accurate delivery into the tumors.
