BPN-14136

BPN-14136 is an orally effective retinol-binding protein 4 (RBP4) inhibitor. BPN-14136 inhibits the binding of retinol to RBP4 with an IC₅₀ of 12.8 nM. BPN-14136 inhibits retinol-dependent RBP4-transthyretin interaction (IC₅₀ = 43.6 nM) and reduces circulating plasma RBP4 levels in vivo. BPN-14136 decreases the formation of cytotoxic bisretinoids in retinal pigment epithelial cells. BPN-14136 can be used for the research of atrophic age-related macular degeneration and Stargardt disease.

HEK293	IC₅₀	30 μM Compound: 33	Inhibition of human ERG expressed in HEK293 cells by patch clamp assay Inhibition of human ERG expressed in HEK293 cells by patch clamp assay	[PMID: 26181715]

In Vitro

BPN-14136 (Compound 33) (10 μM; 30 min) shows excellent stability in human and rat liver microsome assays, with 94% and 93% remaining after 30 min of incubation at 10 μM, respectively^[1].
BPN-14136 has a favorable in vitro ADMET profile, including high solubility, very low hepatic clearance, no significant CYP or hERG inhibition, high plasma protein binding, and high MDR1-MDCK permeability^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
