Efficient and Targeted Suppression of Human Lung Tumor Xenografts in Mice with Methotrexate Sodium Encapsulated in All‐Function‐in‐One Chimeric Polymersomes

Anisamide-functionalized reversibly crosslinked chimeric polymersomes emerge as an "all-function-in-one" nanoplatform for efficient loading and targeted delivery of methotrexate disodium, a potent water-soluble anticancer drug, to sigma receptor overexpressing H460 nonsmall lung cancer xenografts in vivo, leading to markedly improved tumor-growth inhibition and survival rate and depleted adverse effects as compared to the clinically used formulation (Trexall).
