The folate receptor (FR) was identified in 1986 and has been established as a ‘molecular Trojan Horse’ target for the uptake of folate-conjugated organic molecules into cells. The FR is overexpressed in many malignancies, including those of the ovary, uterus, breast, cervix, and prostate, yet it is reportedly under-expressed in normal healthy cells. This difference in expression and the high affinity/specificity of folate towards the folate receptor presents a promising drug delivery system. The aim of this research was to utilise folic acid as a targeting moiety and generate simple metal folate and novel folate-phenanthroline complexes with cytotoxic properties. A …

Purpose Thermoresponsive hydrogels are gels which have different properties at varying temperatures. The objective of this study was to assess the material characteristics, imaging properties and chemotherapeutic drug release profile of a novel radiopaque thermoresponsive hydrogel in vitro, which is liquid at room temperature but solidifies at body temperature, to determine potential suitability for intratumoural delivery. Materials and Methods An iodinated radiopaque thermoresponsive hydrogel was formulated using iodixanol at a range of concentrations and assessed for sol–gel transition, radiopacity and imaging using CT and US. A lead formulation containing iodixanol at a concentration of 9.22% weight by weight (w/w, g …
