f-box

PEO-IAA (2-(1H-Indol-3-yl)-4-oxo-4-phenyl-butyric acid) is a novel potent auxin antagonist.

SMER3 is an inhibitor of the Skp1-Cullin-F-box (SCF)(Met30) ubiquitin ligase, a member of the SCF E3-ligase family, which regulates diverse cellular processes including transcription, cell-cycle control and immune response.

BC-1215 is an inhibitor of F-box protein 3 (FBXO3, a ubiquitin E3 ligase component, IC50=0.9 μg mL for IL-1β release).

Skp2 inhibitor 2 (14f) impedes the F-box protein S-phase kinase-associated protein 2 (Skp2), demonstrating an IC50 of 10.2 μM against Skp2-Cks1. This compound targets Skp2, a component of cullin-RING ligases that recruits and ubiquitinates substrates, playing roles in both proteolytic and non-proteolytic processes [1].

BC-1258 is a unique small molecule F-box LRR-repeat protein 2 (FBXL2) activator.
