Application

New Methylene Blue N zinc chloride double salt has been used as a photosensitizer for the in vitro photodynamic inactivation of plant-pathogenic fungi Colletotrichum acutatum and Colletotrichum gloeosporioides. It has also been used to determine the in vitro susceptibilities of Trichophyton mentagrophytes and Trichophyton rubrum microconidia to photodynamic antimicrobial chemotherapy (PACT).

Biochem/physiol Actions

New Methylene Blue N zinc chloride double salt also known as methylene blue N is an azo dye. It can bind, neutralize and crosslink with RNA. This causes co-precipitation of ribosomal and residual RNA with the mitochondria and ferritin masses. These events make the living, young erythrocytes as microscopically visible, dark-blue clusters and filaments, referred to as reticulum. New Methylene Blue N zinc chloride double salt helps in counting of reticulocytes (erythrocytes containing RNA).

Antimicrobial photodynamic treatment (APDT) has emerged as an effective therapy against pathogenic fungi with both acquired and intrinsic resistance to commonly used antifungal agents. Success of APDT depends on the availability of effective photosensitizers capable of acting on different fungal
