Biological Activity

Description

3BDO, a butyrolactone derivative, could target FKBP1A and activate the mTOR signaling pathway. It inhibits autophagy in HUVECs. This compound inhibits oxLDL-induced apoptosis.

Targets

FKBP1A ^[1]
(Cell-free assay)

In vitro

3BDO inhibits autophagy in human umbilical vein endothelial cells (HUVECs) and neuronal cells. It suppresses lipopolysaccharide-induced HUVEC autophagic injury by downregulating the protein levels of NUPR1 (nuclear protein, transcriptional regulator) and TP53 (tumor protein p53), TP53 nuclear translocation and reactive oxygen species overproduction. This compound activates MTOR by targeting FKBP1A (FK506-binding protein 1A, 12 kDa). It greatly decreases the level of a long noncoding RNA (lncRNA) derived from the 3′ untranslated region (3′UTR) of TGFB2, known as FLJ11812, but does not affect TGFB2 expression. ATG13 protein level is decreased along with this compound-decreased FLJ11812 level. It inhibits excessive Aβ (25 to 35) peptide-induced autophagy in PC12 neuronal cells and increased the phosphorylation of RPS6KB1. This chemical could inhibit human umbilical vein EC (HUVEC) apoptosis and senescence induced by deprivation of serum and basic fibroblast growth factor 2. iT selectively protecteS vascular ECs (VECs) and inhibitS vascular smooth muscle cell (VSMC) proliferation and migration. It (20-60 μg/ml) could inhibit VEC apoptosis and suppress integrin β4 expression, but it could not depress the ROS level induced by deprivation of serum and FGF-2.

In vivo

In vivo experiments showed that 3BDO had a good safety profile. This compound treatment could significantly reduce the number of autophagosomes and improve neuronal function in App and Psen1 transgenic mice. It activated mTOR in vivo and decreased the protein level of ATG13 in the plaque endothelium of apoE-/- mice. It does not affect the activity of mTOR and autophagy in macrophage cell line RAW246.7 and vascular smooth muscle cells of apoE-/- mice, but suppressed plaque endothelial cell death and restricted atherosclerosis development in the mice. This chemical protecteS VECs by activating mTOR and thus stabilized atherosclerotic lesions in apoE-/- mice.

Protocol (from reference)

Cell Assay:^{^[1]}	Cell lines HUVECs Concentrations 60 μM Incubation Time 24 h Method HUVECs are cultured in M199 medium with 20% (v/v) fetal bovine serum and 10 IU/mL fibroblast growth factor 2 (FGF2) in a humidified incubator at 37 °C with 5% CO2. When HUVECs were grown to 80% confluency, cells were treated with or without this compound. HUVECs were treated with DMSO or 60 µM of this chemical for 24 h, then total RNA was extracted with use of Trizol reagent. The cDNA microarray assay in response to this compound treatment was performed.
