15-deoxy-Δ12,14-PGJ2-d4 contains four deuterium atoms at the 3, 3′, 4, and 4′ positions. It is intended for use as an internal standard for the quantification of 15-deoxy-Δ12,14-PGJ2 by GC- or LC-mass spectrometry. 15-deoxy-Δ12,14-Prostaglandin J2 (15-deoxy-Δ12,14-PGJ2) is a metabolite of PGJ2. 15-deoxy-Δ12,14-PGJ2 is formed from PGD2 by the elimination of two molecules of water. It binds selectively to PPARγ with an EC50 of 2 µM in a murine chimera system.{1424,1428} 15-deoxy-Δ12,14-PGJ2 is more potent than PGD2, Δ12-PGJ2, and PGJ2 in stimulating lipogenesis in C3H10T1/2 cells. The EC50 for induction of adipocyte differentiation in cultured fibroblasts is 7 µM.{1424}

The tetracycline repressor (TetR) is a transcriptional regulator which normally binds tightly to its palindromic tetO operator DNA, blocking gene expression.{17508} Tet causes the repressor to dissociate from the DNA, allowing transcription to occur. A novel reverse TetR (revTetR) requires tetracycline as a co-repressor to bind tetO and block transcription.{17509,17510} Anhydrotetracycline (hydrochloride) is a powerful effector in both the tetracycline repressor (TetR) and reverse TetR (revTetR) systems, binding the Tet repressor 35-fold more strongly than Tet.{17508,17511} Moreover, anhydrotetracycline poorly binds the 30S ribosomal subunit, compared to Tet,{17512} so it does not act as a general inhibitor of translation and is a poor antibiotic. Perhaps related to this, the concentration of anhydrotetracycline that inhibits eukaryotic cell growth is more than a 1,000-fold above the dose that alters transcription through TetR.{17508}

The PtdIn phosphates play an important role in the generation and transduction of intracellular signals.{8344,4096,14518} PtdIns-(3,4,5)-P3-biotin is an affinity probe which allows the PIP3 to be detected through an interaction with the biotin ligand. This design allows PtdIns-(3,4,5)-P3-biotin to serve as a general probe for any protein with a high affinity binding interaction with inositol-(3,4,5)-triphosphate phospholipids, such as phosphatidylinositol 3-kinase, PTEN, or PH-domain-containing proteins.

The nuclear factor-κB (NF-κB) regulates the expression of numerous genes involved in immunity and inflammation, cellular stress responses, growth, and apoptosis. Resveratrol, a polyphenolic trans-stilbene, is a known inhibitor of the activation of NF-κB and exhibits activity against a wide variety of cancer cells. CAY10512 is a substituted trans-stilbene analog of resveratrol that is 100-fold more potent as measured by antioxidant activity. The IC50 value for inhibition of TNFα-induced activation of NF-κB by CAY10512 is 0.15 µM compared to 20 µM by resveratrol.{14545}
