Background:

SLF TFA is a synthetic ligand for FK506-binding protein (FKBP) with an affinity of 3.1 μM for FKBP51 and an IC50 of 2.6 μM for FKBP12. SLF TFA can be used in the synthesis of PROTAC[1][2][3].

Three scout fragments-KB02, KB03, and KB05 are fused, which cover two different electrophile groups (chloroacetamide and acrylamide) and display broad cysteine reactivity in the human proteome-to the SLF ligand that binds tightly and selectively to FKBP12, a cytosolic prolyl isomerase that has been frequently used to study ligand-induced protein degradation[3].
