Description

Application

Alexidine dihydrochloride has been used:

• as an antiseptic to study its antimicrobial activity in saliva-derived microcosm biofilms[1]
• as a protein tyrosine phosphatase localized to the mitochondrion 1 (PTPMT1)-specific inhibitor to study its effects on spare respiratory capacity and viability of CD8⁺ T cells[2]
• as a PTPMT1 inhibitor to study its antiviral effect on  human cytomegalovirus (HCMV) replication in HCMV-infected human foreskin fibroblast (HFF) cells[3]

Biochem/physiol Actions

Alexidine dihydrochloride is a bisbiguanide compound. It has been studied in the treatment of head and neck cancer.[4] Alexidine dihydrochloride also exhibits antibiofilm and antifungal activity against several fungal species. It causes mitochondrial apoptosis in mammalian cells due to its anti-cancer activity.[5] Alexidine dihydrochloride is a component of oral disinfectant and contact lens solution.[6]

Alexidine dihydrochloride is a potent and selective PTPMT1 (Protein Tyrosine Phosphatase Localized to the Mitochondrion 1) inhibitor. Alexidine increases insulin secretion by isolated rat pancreatic islets.
