Description

General description

A cell-permeable, non-toxic, indolinyl-thiazole based compound that acts as a highly potent, reversible inhibitor of lipid uptake via scavenger receptor class B type I (SR-BI; IC₅₀ = 6 nM). Shown to block the uptake of [³H] labeled cholesteryl oleate ester ([³H]CE) from [³H]CE-HDL (IC₅₀ = 7 nM). Exhibits high selectivity when tested against a panel of 67 different receptors and secondary targets (at 10 µM). Displays excellent stability in human plasma (99% remaining after 5 h, with 94% plasma protein bound) and mouse liver microsomes (75% remaining after 1 h).

Please note that the molecular weight for this compound is batch-specific due to variable water content. Please refer to the vial label or the certificate of analysis for the batch-specific molecular weight. The molecular weight provided represents the baseline molecular weight without water.
