PT-179
PT-179 is an orthogonal Thalidomide (HY-14658) derivative that targets cereblon without causing off-target degradation effects. PT-179 is able to specifically bind CRBN, form a ternary complex with a target protein fused to a zinc finger (ZF) degron, and mediate the degradation of the tagged protein. For example, PT-179 binds to the ubiquitin ligase substrate receptor cereblon by forming a complex with SD40 and efficiently degrades proteins N- or C-terminally fused to SD40 or SD36 (DC50 for eGFP: 4.5 nM and 14.3 nM). PT-179 can be used to develop compact protein degradation tagging platforms[1]. Uses: Scientific research. Group: Signaling pathways. CAS No. 2924858-25-1.
