Description

HC278 is a selective TEAD1/TEAD3 PROTAC degrader. HC278 induces proteasome-dependent degradation by forming a stable ternary complex with CRBN/DDB1. HC278 is applicable to the research of mesothelioma[1].

In Vitro

HC278 (50-500 nM; 2-18 h) is a bona fide, proteasome- and CRBN-dependent PROTAC that potently and selectively degrades TEAD1 and TEAD3 in HEK293 stable cells expressing epitope-tagged TEAD1-4, with significant degradation observed at 50 nM, while having minimal effect on TEAD2 and weak activity against TEAD4 at 500 nM[1].
HC278 (100-200 nM; two weeks) specifically inhibits the colony-forming ability of YAP-dependent NCI-H226 mesothelioma cells at 200 nM, while having no effect on NCI-H28 control mesothelioma cells[1].
HC278 (500 nM; 24 h) inhibits TEAD/YAP transcriptional activity in NCI-H226 mesothelioma cells, significantly downregulating YAP signature genes and specific target genes including CTGF, CYR61, and ANKRD1 at 500 nM for 24 h[1].
HC278 (500 nM-1 μM; 24 h) downregulates YAP target gene expression (CTGF, CYR61, ANKRD1) in MDA-MB-231 cells at 500 nM and 1 μM for 24 h[1].

Concentration: 50 nM; 500 nM
Incubation Time: 2 h, 4 h, 6 h, 8 h, 10 h, 12 h, 14 h, 16 h, 18 h
Result: Degraded TEAD1 and TEAD3 by more than 50% at 50 nM.

Detected TEAD1/3 degradation as early as 2 h after treatment, with degradation increasing over time.
Completely blocked TEAD degradation when co-treated with 1 μM MG132.
Inhibited TEAD degradation activity when co-treated with 500 nM Ex.

Showed much weaker degradative effect for negative control HC278-Neg1, and failed to induce TEAD degradation for negative control HC278-Neg2.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
