Oxymatrine, a quinoline alkaloid derived from Sophora flavescens, exhibits an inhibitory effect on the Malassezia biofilm

Malassezia, a fungus linked to various skin disorders, has recently been implicated in cancer development. Psoriasis, a chronic skin condition driven by genetic and environmental factors, exhibits significant microbial imbalance, where Malassezia restricta and M. globosa are prevalent in lesions. Given the rising antifungal resistance and toxicity, discovering novel compounds targeting Malassezia is imperative. In this context, the research led by Dr. Qiming Wang (Hebei University) highlights the urgency for innovative therapies.

Oxymatrine, a bioactive compound derived from the Chinese herb Sophora flavescens, has been clinically used in psoriasis treatment. Compared to conventional antifungals, it demonstrates lower toxicity, milder side effects, and potent inhibitory activity against Malassezia biofilm formation.

"Oxymatrine not only controls Malassezia overgrowth but also manages psoriasis symptoms, offering a dual-action mechanism for safer and more effective therapy," said Professor Qiming Wang. Further studies reveal its ability to suppress inflammatory responses in psoriatic lesions, alleviating skin damage and reducing apoptosis.

"This anti-inflammatory effect synergizes with its antifungal properties, providing a comprehensive therapeutic strategy," explained Professor Wang. The findings position oxymatrine as a promising solution for addressing both microbial dysbiosis and inflammation in psoriasis.
