* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description

TVB-3166 is an orally-available, reversible, potent and selective inhibitor of fatty acid synthase (FASN) with IC50 of 0.042 μM in an in vitro biochemical assay. TVB-3166 induces apoptosis, and inhibits in-vivo xenograft tumor growth.

Targets

FASN ^[1]
(Cell-free assay)

0.042 μM

In vitro

TVB-3166, a FAS inhibitor, assesses its ability to inhibit SARS-CoV-2-mNG infection with an EC50 of 11 nM.^[2]

Protocol (from reference)

Cell Assay:^{^[2]}	Cell lines HEK293T-hACE2, Caco-2 and MEF-hACE2 cells Concentrations 320 nM Incubation Time 16 h Method HEK293T-hACE2 (1 × 10⁵ cells per well), Caco-2 (2 × 10⁵ cells per well) or MEF-hACE2 cells (5 × 10⁴ cells per well) were seeded in 24-well plates in culture medium and incubated at 37 °C, 5% CO2 cell culture incubator. Inhibitor dose titration is a fourfold serial dilution of selected eight inhibitors with different starting concentrations of 20 µM (orlistat, FASN-IN-4, FT113), 320 nM (TVB-2640, TVB-3166, GSK-214069) or 80 nM (TVB-3664, remdesivir). Diluted inhibitors were added to the cells 16 h before infection and maintained in the medium during infection. After being transferred to the BSL3 facility, pre-treated cells were infected with the SARS-CoV-2-mNG virus (icSARS-CoV-2-mNG) with an MOI of 0.01. Fluorescence assay and quantification of SARS-CoV-2 infection were performed at 24 h after infection.
