In Vitro AEBSF inhibits the constitutive production of Aβ by directly inhibiting β-secretase in five different human cell lines, both neural and nonneural[1]. AEBSF, as a serine protease inhibitor, inhibits the lysis of leukemic cells by human macrophages without inhibiting macrophage secretion of TNF-α and IL-1β[2]. AEBSF also disturbs the growth of blastocysts on endometrial cells and inhibit the adhesion of HeLa cells on HUVECs by altering the protein secretion pattern[4].
In Vivo AEBSF (76.8 mg/kg daily, i.p.) results in prolongation of the survival of mice that have been given a lethal T. gondii infection[3]. AEBSF also reduces airway response and underlying inflammation in cockroach allergen-induced murine model[4].
Cell Assay The HeLa cells suspended in RPMI-1640 media containing 10% FCS are plated into each well of a 96-well microplate (5×103 cells/200 μL/well). After incubation for 24 h at 37°C, cells are treated with different doses of AEBSF (0, 25, 50, 100 μg/mL) for 48 h. Then, 20 μL fresh 3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-diphenytetrazoliumromide (MTT) reagent (5 μg/μL) is added into each well, and cells are cultured at 37°C in 5% CO2 for another 4 h. The media are discarded carefully, and 150 μL DMSO is added. Absorbance is read on a microplate reader at dual wavelengths of 540 and 620 nm.
Animal Admin Mice injected with 2.5×103 parasites are randomLy assigned to one of the treatment groups according to the treatment given: without drugs (control group), vehicle alone (vehicle control group), pyrimethamine alone at different doses, LY311727 alone at different doses, AEBSF alone at different doses or AEBSF 76.8 mg/kg plus pyrimethamine 10 mg/kg. Each treatment group consists of 10 animals. Treatment is initiated 24 h after parasite inoculation and is continued for seven consecutive days. Mouse survival is monitored daily and continued in live mice until 15 days post-infection. All experiments are performed three times and the data shown represent the cumulative results.
