Modulight Spotlights: LASER-SHARP RESEARCH – February 2024

 Modulight Spotlights: LASER-SHARP RESEARCH – February 2024 Photoactivated chemotherapy (PACT) is a novel anticancer therapy where cytotoxic drug is attached into a photocage, which is cleaved by light to release the drug at the tumor site. A new study led by Prof. Sylvestre Bonnet’s group at Leiden University, demonstrated a significantly improved agent for photoactivated chemotherapy. ML6600 laser was used to study the drug release from the photocage, comparing efficacy between red and green light. It was shown that the agent could be effectively released Continue reading →

Red-Light Activation of a Microtubule Polymerization Inhibitor via Amide Functionalization of the Ruthenium Photocage

Le Dévédec, Tania Betancourt, Alexander Kornienko, Sylvestre Bonnet Leiden University A ruthenium-based compound was developed for PACT (photoactivated chemotherapy), which unlike most existing PACT compounds, can be also activated with clinically relevant longer (red) wavelength of light. ML6600 was used for in vivo experiments to superficially activate PACT compound in subcutaneous tumor comparing green and red wavelengths. The tumor volume reduction was Continue reading →
