MedKoo CAT#: 571472

CAS#: 384376-42-5

Description: D75-4590 is a β-1,6-Glucan inhibitor. These inhibitors work as antifungal drugs by targeting the fungal cell wall. As glucan is a major component of the cell wall, specifically β-1,6-Glucan, these drugs can help fight fungal infections by degrading glucan or stopping production by inhibiting its synthase. D75-4590 is a pyridobenzimidazole derivative that achieves this function, and is effective against Candida strains (even fluconazole-resistant strains). D11-2040 and D21-6076 are antifungal derivatives of D75-4590.

Additional Information

There is increasing morbidity and mortality resulting from invasive fungal infections (IFIs) and antifungal drug resistance. As a result, several drug therapies are addressing the need by discovering and designing new antifungal drug targets and mechanisms, specifically against the most common fungi causing IFIs: Candida, Cryptococcus, and Aspergillus species. Existing drugs (polyenes, azoles, and echinocandins) have limited clinical efficacy, narrow antifungal spectrum, unfavorable pharmacokinetic profiles, significant side effects, drug−drug interactions, and resistance issues.
