slf

SLF is a synthetic ligand for FK506-binding protein (FKBP) with an affinity of 3.1 μM for FKBP51 and an IC50 of 0.22 μM for FKBP12. SLF can be used in the synthesis of PROTAC.

KB02-SLF is a PROTAC-based nuclear FKBP12 degrader, also known as a molecular glue, that facilitates the degradation of nuclear FKBP12 by covalently modifying DCAF16, an E3 ligase. SLF acts as a linker, binding to the ubiquitin E3 ligase ligand KB02, thus forming KB02-SLF[1] and enhancing the longevity of protein degradation in biological systems.

SLF TFA, a synthetic ligand for FK506-binding protein (FKBP), exhibits affinity toward FKBP51 with a value of 3.1 μM and demonstrates an IC50 of 2.6 μM for FKBP12. This compound is utilized in the synthesis of PROTAC [1] [2] [3].

SLF-amido-C2-COOH is a synthetic ligand for FKBP (SLF), and can be used in the synthesis of PROTACs.

AUTAC2, an autophagy-mediated degrader (AUTAC) targeting FKBP12, comprises an FBnG (p-Fluorobenzyl Guanine) and an SLF (c ligand of FKBP) moiety. The SLF component binds non-covalently to FKBP12 [1].

KB02-COOH is a synthetic fragment derived from ubiquitin E3 ligase ligand KB02, which possesses potential utility in the synthesis of PROTAC compounds. Notably, KB02-COOH can be employed in the generation of PROTAC constructs like KB02-JQ1 and KB02-SLF.

dFKBP-1 is a potent PROTAC-based FKBP12 degrader incorporating the FKBP12 ligand SLF, the Thalidomide-based cereblon ligand, and a linker[1].

TSPO ligand-3, functioning as an AUTAC2 ligand, incorporates both a p-fluorobenzylguanine (FBnG) and a synthetic ligand of FKBP (SLF) moiety, leading to the substantial inhibition of FKBP12 in HeLa cells [1].
