NSC-134754
NSC-134754 (NZ-28) is a dehydroemetine derivative and heat shock protein (HSP) induction inhibitor. NSC-134754 acts at the post-transcriptional level, targets Hsp72 and Hsp27, and does not alter general protein synthesis, HSF-1 transcriptional activity, or Hsp mRNA levels. NSC-134754 can be used for the research of multiple myeloma, prostate carcinoma, colon carcinoma.
For research use only. We do not sell to patients.

Biological Activity
NSC-134754 inhibits heat shock-induced Hsp72 induction in CHO cells with an IC50 of 1 μM and has a cellular toxicity IC50 of 5 μM[1].
NSC-134754 (1-2 μM; 16 h prior to heat shock) potently inhibits heat shock-induced Hsp72 induction in CHO cells at concentrations of 1 μM and completely inhibits this induction at 2 μM[1].
NSC-134754 (1-2 μM; 24 h) does not inhibit general protein synthesis in CHO cells[1].
