PT-179 is an orthogonal Thalidomide (M2225) 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. PT-179 (1-10 μM; 24 h) can induce eGFP degradation in HEK293T cells. The higher the evolution degree of the degron variant, the stronger the degradation efficiency of the corresponding tagged protein. SD40 is a degradation tag specific for PT-179. 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.

| Pomalidomide
Pomalidomide is the third-generation immunomodulatory agent, functions through interacting with the E3 ligase cereblon and induces degradation of essential Ikaros transcription factors. Pomalidomide is a second generation immunomodulator, TNF-α inhibitor with IC50 of 13 nM. |
| Thalidomide
Thalidomide is a sedative and immunomodulator used to study the symptoms of many cancers, it has immunomodulatory, anti-inflammatory and anti-angiogenic cancer properties.
