Description: Lemuteporfin, also known DRM05, QLT-0074 , is a diester derivative of benzoporphyrin derivative, is a neutral, uncharged benzoporphyrin molecule having symmetrical diethylene glycol groups; this maintains its amphiphilic character. It differs from another benzoporphyrin derivative, verteporfin, as it is a single regioisomer. verteporfin, consists of two regioisomers present in equal proportions and is negatively charged at neutral pH.

Photocytotoxicity assays in vitro showed that lemuteporfin is a potent photo sensitizer with very little cytotoxicity at high concentrations (>3.0 microM) in the absence of light. Cytotoxicity and fluorescence quantification studies indicated rapid uptake and release of the photosensitizer by L1210 cells. The photosensitizer was taken up by rapidly proliferating L1210 cells and Con A activated splenocytes to a greater extent than by unstimulated splenocytes. Mouse studies revealed rapid delivery of lemuteporfin to plasma and skin. The capacity of lemuteporfin to photosensitize skin and control tumor growth was greatest at relatively early (30 min or less) light exposure times, indicating rapid clearance kinetics in vivo. Thus, lemuteporfin may be useful in therapies where a high potency and rapid clearance are required, thus minimizing the potential for unwanted skin photosensitivity.

Lemuteporfin is a highly potent and selective topical photodynamic therapy (PDT) approach to sebaceous gland targeting for moderate to severe acne. The anticipated clinical profile for lemuteporfin will be to obtain substantial anti-sebaceous gland effects, approaching AccutaneTM efficacy in acne, with no risk of systemic toxicity or damage to surrounding skin structures. The cellular uptake of lemuteporfin was rapid, with maximum levels reached within 20 min. Mitogen-activated lymphoid cells accumulated more of the lemuteporfin than their quiescent equivalents, supporting selectivity. Photosensitizer fluorescence in the skin increased rapidly within the first few minutes following intravenous administration to mice, then decreased over the next 24 h. Skin photosensitivity reactions indicated rapid clearance of the photosensitizer.
Lemuteporfin shares an absorption spectrum typical of benzoporphyrin derivatives and can be activated with light in the ultraviolet, blue and red parts of the spectrum. Favorable characteristics of benzoporphyrin photosensitizers include their absorption peak near 690 nm, a wavelength that penetrates tissue relatively efficiently. Another advantage is that upon activation, there is a high quantum yield of singlet oxygen. Lemuteporfin is presently being investigated clinically in photodynamic therapy.
