Hazard Information

Uses

HSP90-IN-9 is a potent and selective HSP90 inhibitor. HSP90-IN-9 displays a fungicidal effect in a dose-dependent manner. HSP90-IN-9 inhibits fungal biofilm formation and fungal morphological changes after being combined with FLC. HSP90-IN-9 recovers FLC resistance by down-regulating the expression of related genes (ERG11, CDR1 and CDR2)[1].

in vivo

HSP90-IN-9 (10 mg/kg; i.v.) exhibits moderate pharmacokinetic properties in SD rats^[1].
HSP90-IN-9 (A17 (10 mg/kg)+FLC (1 mg/kg); i.p.; once a day for 5 days) exhibits potent in vivo antifungal efficacy by reducing the colonization and dissemination of fungi in tissue^[1].
