Specific link between high fructose uptake and cancer development and progression highlighted fructose transporters as potential means to achieve GLUT-mediated discrimination between normal and cancer cells. The gained expression of fructose-specific transporter GLUT5 in various cancers offers a possibility for developing cancer-specific imaging and bioactive agents. Herein, we explore the feasibility of delivering a bioactive agent through cancer-relevant fructose-specific transporter GLUT5. We employed specific targeting of GLUT5 by 2,5-anhydro-D-mannitol and investigated several drug conjugates for their ability to induce cancer-specific cytotoxicity. The proof-of-concept analysis was carried out for conjugates of chlorambucil (CLB) in GLUT5-positive breast cancer cells and normal breast cells. The cytotoxicity of conjugates was assessed over 24 h and 48 h, and significant dependence between cancer-selectivity and conjugate size was observed. The differences were found to relate to the loss of GLUT5-mediated uptake upon increased conjugate size and hydrophobicity. The findings provide information on the substrate tolerance of GLUT5 and highlight the importance of maintaining appropriate hydrophilicity for GLUT-mediated delivery.

The design, synthesis and spectroscopic properties of novel polymerizable coumarin-based pH indicators are reported. They show a fluorescence response to pH in the highly alkaline pH region with calculated pKa values in the range of 12.2–12.5. Covalent immobilization of the indicators to polymer supports provides novel pH-sensitive materials that possess excellent photostability. The materials are sensitive to pH in a similar range and can be applied in optical pH sensors for measuring pH in various alkaline media.

Two series of coumarin-1,2,3-triazole-dithiocarbamate hybrids were designed, synthesized and evaluated for their inhibitory activity towards lysine specific demethylase 1 (LSD1). Compounds 8a, 8d-8f, 8i-8l presented potent activity against lysine specific demethylase 1. Among them, compound 8k showed potent and reversible inhibition against lysine specific demethylase 1 with an IC50 value of 0.39 μM, which was 74-fold more potent than that of tranylcypromine (2-PCPA). Besides, compound 8k displayed excellent selectivity against lysine specific demethylase 1 without inhibition against monoamine oxidases (MAOs) A and B. Further investigation revealed that compound 8k was active at both recombinant and cell levels by upregulating the expression of H3K4me1, H3K4me2 and H3K9me2.
