Overview

In vitro study demonstrates enhanced drug uptake and potency using dye-conjugated crizotinib in patient-derived glioblastoma cells, highlighting a promising delivery strategy across brain barriers.

Key Points

To determine how chemical substituents on blood–brain barrier-crossing heptamethine cyanine dyes affect cellular uptake and anticancer potency when conjugated to crizotinib.
Synthesized conjugates linking the targeted kinase inhibitor crizotinib to heptamethine cyanine dyes modified with distinct functional groups.
Evaluated in vitro cellular uptake and antiproliferative activity across four patient-derived glioblastoma cell lines.
Heptamethine cyanine dye functionalization enhanced intracellular delivery of crizotinib across all evaluated patient-derived cell models.
Increased intracellular conjugate accumulation directly improved cytotoxic potency relative to parent compounds.
