Ibrexafungerp: An orally active β-1,3-glucan synthesis inhibitor

We previously reported medicinal chemistry efforts that identified MK-5204, an orally efficacious β-1,3-glucan synthesis inhibitor derived from the natural product enfumafungin. Further extensive optimization of the C2 triazole substituent identified 4-pyridyl as the preferred replacement for the carboxamide of MK-5204, leading to improvements in antifungal activity in the presence of serum, and increased oral exposure. Reoptimizing the aminoether at C3 in the presence of this newly discovered C2 substituent, confirmed that the (R) t-butyl, methyl aminoether of MK-5204 provided the best balance of these two key parameters, culminating in the discovery of ibrexafungerp, which is currently in phase III clinical trials. Ibrexafungerp displayed significantly improved oral efficacy in murine infection models, making it a superior candidate for clinical development as an oral treatment for Candida and Aspergillus infections.

1,3-β-Glucan synthase inhibitor Triterpenoid antifungal agent

Fungal pathogens are responsible for a large number of mild to severe infections worldwide resulting in 1.6 million deaths. With the rapid emergence of drug resistance, the treatment of fungal infections is rapidly becoming unmanageable. Thus, the discovery and development of novel antifungal drugs is an unmet need of the hour. In this context, ibrexafungerp (SCY-078; SCYNEXIS) is the first orally bioavailable agent that has activity against β-glucan synthase, an essential component of the cell wall. It has broad-spectrum activity against a wide range of Candida sp, including those that are resistant to echinocandins. In addition, ibrexafungerp exhibits broad-spectrum fungicidal activity including against multidrug-resistant strains, possesses high tissue penetration and exhibits flexible dosing options including via oral and intravenous routes. The U.S. Food and Drug Administration has granted both qualified infectious disease product and fast track designations for the oral formulation of ibrexafungerp for the treatment and prevention of recurrent vulvovaginal candidiasis.
