Description: ADPM06 is an emerging non-porphyrin PDT agent which has been specifically designed for therapeutic application. It was demonstrated that ADPM06-PDT was well tolerated in vivo and elicited impressive complete response rates in various models of cancer when a short drug-light interval was applied. Using a drug and light combination that reduced the clonogenicity of MDA-MB-231 cells by >90%. PDT-induced apoptosis was also found to be independent of p53 tumor suppressor status. A robust therapeutic response in vivo was demonstrated, with a substantial reduction in tumor proliferation observed, as well as a rapid induction of apoptosis and initiation of ER stress, mirroring numerous aspects of the mechanism of action of ADPM06 in vitro. Finally, using a combination of (18) F-labeled 3'-deoxy-3'-fluorothymidine ((18) F-FLT) nuclear and optical imaging, a considerable decrease in tumor proliferation over 24-hr in two models of human cancer was observed. Taken together, this data clearly establishes ADPM06 as an exciting novel PDT agent with significant potential for further translational development.

ADPM06 is a totally new class of nonporphyrin photodynamic therapeutic agent. Confocal laser scanning microscopy imaging showed that this compound is exclusively localised to the cytosolic compartment, with specific accumulation in the endoplasmic reticulum and to a lesser extent in the mitochondria. Light-induced toxicity assays, carried out over a broad range of human tumour cell lines, displayed EC50 values in the nano-molar range for ADPM06, with no discernable activity bias for a specific cell type. Strikingly, the more active agent, ADPM06, even retained significant activity under hypoxic conditions. This photosensitiser showed low to nondeterminable dark toxicity. Flow cytometric analysis revealed that ADPM06 is highly effective at inducing apoptosis as a mode of cell death. The photophysical and biological characteristics of these PDT agents suggest that they have potential for the development of new anticancer therapeutic [source: Br J Cancer. 2005 May 9;92(9):1702-10.]
A recent in vivo study, using a multi-modality imaging approach to assess efficacy of treatment as well as probe the mechanism of action of ADPM06-mediated PDT, showed that tumor ablation in 71% of animals bearing mammary tumors was achieved after delivery of 2 mg/kg-1 of ADPM06 followed immediately by light irradn. with 150 J/cm-2. The inherent fluorescence of ADPM06 was utilized to monitor organ biodistribution patterns, with fluorescence reaching baseline levels in all organs within 24 h. Mechanism of action studies were carried out using dynamic positron emission tomog. and magnetic resonance imaging techniques, which, when taken together, indicated a decrease in tumor vascular perfusion and concomitant redn. in tumor metab. over time after treatment. The encouraging treatment responses in vivo and vascular-targeting mechanism of action continue to indicate therapeutic benefit for this new class of photosensitizer.
