Furthermore, this review positions mavorixafor within the broader CXCR4-targeted therapeutic landscape, identifying current research gaps and suggesting directions for future studies. In conclusion, by integrating mechanistic insights with preclinical and clinical findings, this article highlights mavorixafor's promise as a targeted therapy with the potential to transform treatment paradigms for CXCR4-driven diseases.
Antagonistic peptides AMD3100 (Plerixafor), LY2510924, and POL6326, as well as their therapeutic potential. Future research on Mavorixafor will focus on two main areas: personalized medicine development, new delivery systems and their broad medical applications extending beyond oncology. As a potential CXCR4 antagonist, Mavorixafor shows promise as a transformative tool in cancer care because it regulates the tumor microenvironment (TME) while increasing the degree of therapeutic benefits.
These are based mainly on nitrogen-rich scaffolds, such as AMD070, and cyclic polyamines such as cyclam in the AMD3100 skeleton. Herein, we describe the synthesis of two novel CXCR4-directed radiopharmaceuticals, combining the AMD070 scaffold as a targeting unit, and bifunctional te1pa macrocycle as a strong 64Cu chelator. The synthesis of the conjugates and optimization of 64Cu-radiolabeling are presented, opening the way for future in vitro and in vivo studies.
Thank to their particular pharmacokinetics, the use of small organic molecules can be a very promising alternative to macromolecular targeting biomolecules (i.e. antibodies, peptides…) for specific imaging of tumours. Herein, the potential of two AMD070-like inhibitors as CXCR4-targeting units for specific imaging of cancer cells, and the influence of chromophore-grafting on their recognition properties has been investigated.
