15,16-Dihydrotanshinone I (DHTS) is a diterpene tanshinone that has been found in the roots of S. miltiorrhiza with diverse biological activities.{39842} DHTS inhibits RHL-2H3 mast cell degranulation with an IC50 value of 14.3 μM and reduces the tyrosine phosphorylation of phospholipase Cγ2 (PLCγ2) and ERK.{39843} It prevents HuR binding to RNA in a cell-free assay (Ki = 3.74 nM) and inhibits the production of TNF mRNA and protein in MCF-7 cells.{39842} DHTS reduces the viability of MCF-7, MDA-MB-231, and SK-BR-3 breast cancer cells with IC50 values of 0.84, 0.92, and 1.2 μM, respectively. It also reduces collagen-induced aggregation of washed rabbit platelets (IC50 = 8.7 μM).{39844} In vivo, DHTS (25 mg/kg per day) reduces tumor growth in an HL-60 leukemia mouse xenograft model by 68% relative to control without decreasing body weight.{39845} In mice with scopolamine-induced learning and memory impairment, DHTS (2-4 mg/kg, p.o.) increases latency to step-through in a passive avoidance test by approximately 3- to 4-fold, and it inhibits acetylcholinesterase in brain homogenate (IC50 = 25 μM).{39846}

  • A powerful effector in both the TetR and revTetR transcriptional regulator systems

    Anhydrotetracycline (hydrochloride) – 100 mg

    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}
