Tailoring renal-clearable zwitterionic cyclodextrin for colorectal cancer-selective drug delivery
Although cyclodextrin-based renal-clearable nanocarriers have a high potential for clinical translation in targeted cancer therapy, their designs remain to be optimized for tumor retention. Here Seoul National University and Chungnam National University report on the design of renal-clearable zwitterionic cyclodextrin for colorectal cancer-selective drug delivery. The optimized cyclodextrin shows a high tumor accumulation and is used for the delivery of doxorubicin and ulixertinib. Higher tumor accumulation and tumor penetration facilitate tumor elimination. The improved antitumor efficacy is demonstrated in heterotopic and orthotopic colorectal cancer models.

Synergistic Antitumor Potency of a Self-Assembling Cyclodextrin Nanoplex for the Co-Delivery of 5-Fluorouracil and Interleukin-2 in the Treatment of Colorectal Cancer

drug delivery, , ,

We are proud to share Milo Malanga‘s most recent collaboration paper with Hacettepe University on creating nanoplexes via cationic cyclodextrin polymer, 5-Fluorouracil, and Interleukin-2 based on the opposite charge interaction of macromolecules without undergoing any structural changes or losing the biological activity of Interleukin-2. In the colorectal tumor-bearing animal model, survival rate, antitumor activity, metastasis, and immune response parameters were assessed using a cyclodextrin derivative, which was found to be safe based on the ALT/AST levels in healthy mice.

Histomorphometric analysis showed that the groups treated with the nanoplex formulation had significantly fewer initial tumors and lung foci when compared with the control. The dual drug-loaded nanoplex could be a promising drug delivery technique in the immunochemotherapy of colorectal cancer.
