SCY-078, a fungicidal β-1,3-glucan synthesis inhibitor administered as intravenous or oral [14C]SCY-078 to rats, was distributed primarily into tissues associated with invasive fungal disease (kidney, lung, liver, spleen, bone marrow, muscle, vaginal tissue, and skin) to levels exceeding those in plasma. Oral fraction absorbed was ∼40%. Elimination was primarily via bile and feces (∼90%) and urine (∼1.5%). Mean half-time was ∼8 h. Quantitative whole-body autoradiography showed a rapid distribution at 8 h and elimination by 168 h postdose.
Keywords: antifungal agents; mass balance.
