Interactions of pluronic block copolymers on P-gp efflux activity: experience with HIV-1 protease inhibitors.

abstract：:The thermodynamic relationship between FI and FII of ethyl 4-aminobenzoate (benzocaine) has been investigated. Slurry conversion experiments show that the transition temperature below which FI is stable is located between 302 K-303 K (29 °C-30 °C). The polymorphs FI and FII have been characterised by infrared spectros...
