描述

一般說明

Glutaminase Inhibitor II,Bis-2-(5-phenylacetamido-1,2,4-thiadiazol-2-yl)ethyl sulfide (BPTES)is a cell-permeable bis-thiadiazole compound that selectivelyinhibits glutaminase-1(GLS1). It does not inhibit the liver-type GLS-2 mitochondrialglutaminase activity. It exerts its effect by inducing an inactive GLS1tetrameric conformation via a 2:1 inhibitor-to-tetramer stoichiometric binding.BPTES blocks the growth under aerobic/ normoxic conditions, and promotes celldeath under hypoxic conditions in P493 B-cell lymphoma cultures invitro, and effectively suppresses P493 tumor expansion in mice invivo.BPTES has been observedto be active in several cancer cells as it prevents cancer cellproliferation.

應用

Glutaminase Inhibitor II, BPTES has been used asa glutaminase inhibitor to study its effects on the release of extracellularvesicles (EVs) in human immunodeficiency virus (HIV-1) infected macrophages.
