Zosuquidar is a modulator of P-glycoprotein (P-gp; Ki = 59 nM).{33874} It restores the sensitivity of P-gp-expressing cancer cells to vinblastine (Item No. 11762), doxorubicin (Item No. 15007), etoposide (Item No. 12092), and paclitaxel (Item No. 10461) when used at 0.1 µM.{33874} It less potently inhibits cytochrome P450 (CYP) isoforms CYP3A, CYP2D6, and CYP2C9 (Kis = 3.8, 25, and 12 µM, respectively).{33875} Zosuquidar does not modulate multidrug resistance-associated protein 1 (MRP-1). Zosuquidar significantly enhances the efficacy of chemotherapeutics in mice implanted with P-gp-expressing tumors.{33874} Through its effects on P-gp, zosuquidar enhances the distribution of P-gp substrates through the blood-brain barrier into the brain.{33873,33876}

    The maintenance of embryonic stem cells in culture typically requires feeder cells and various exogenous factors found in serum. Murine embryonic stem (mES) cells can be maintained in the absence of feeder cells and serum but require the leukemia inhibitor factor (LIF) and bone morphogenic protein (BMP) to prevent differentiation and promote self-renewal.

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

    Anhydrotetracycline (hydrochloride) – 50 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}
