DO264 Chemical Properties,Usage,Production

Description

DO264 is an inhibitor of α/β-hydrolase domain-containing protein 12 (ABHD12; IC₅₀ = 11 nM). It inhibits ABHD12-dependent hydrolysis of lysophosphatidylserine (lyso-PS) in mouse brain membrane lysates (IC₅₀ = 2.8 nM) and human THP-1 cells. DO264 increases levels of chemokine (C-C motif) ligand 3 (CCL3), CCL4, TNF-α, and IL-1β in M1-polarized THP-1 macrophages. It potentiates ferroptotic cell death induced by the glutathione peroxidase 4 (GPX4) inhibitor RSL3 in HT1080 fibrosarcoma and SU-DHL-5 B cell lymphoma cells when used at a concentration of 1 μM. In vivo, DO264 (30 mg/kg per day for four weeks) increases levels of 1-stearoyl-2-hydroxy-sn-glycero-3-PS, 1-arachidonoyl-2-hydroxy-sn-glycero-3-PS, 1-docosanoyl-2-hydroxy-sn-glycero-3-PS, 1-stearoyl-2-arachidonoyl-sn-glycero-3-PS, and 1-oleoyl-2-arachidonoyl-sn-glycero-3-PS in mouse brain. It increases levels of CCL2, CCL3, and CCL5 in bronchoalveolar lavage fluid (BALF) and decreases survival in a mouse model of infection with lymphocytic choriomeningitis virus (LCMV) clone 13 when administered at a dose of 30 mg/kg.

Uses

DO264 is a potent inhibitor of ABHD12 (α/β-hydrolase domain-containing 12) which shows negligible interaction with other serine hydrolases as determined by activity-based protein profiling.
