Antifungal activity and significant efficacy against a Pneumocystis carinii infected mouse model Benanomicin A

Date：July 03 2020Web Page No：520046

Benanomicin A is isolated from the culture fluid of Actinomadura sp. MH193-16F4.^1,2) It shows excellent activities against a wide range of fungi including Candida, Cryptococcus and Aspergillus.^1,3) Also, benanomicin A demonstrated excellent therapeutic efficacy against in a Pneumocystis carinii-infected mouse model.⁴⁾ Moreorver, benanomicin A prevented human T-cells from HIV-1 at 30-100 µg/mL and inhibited syncytium formation by HIV-1 at 10-100 µg/mL.⁵⁾
The antifungal and anti HIV-1 activities of benanomicins and their analogues have been studied.⁶⁾ Benanomicin A has antimycotic activities via binding to mannan in the cell walls of fungi.⁷⁾ In recent years, the lectin-like functionality of Benanomicin A has been utilized to conduct research on preparing the mannan cell walls.^8,9)
