Anhydrotetracycline (hydrochloride)
Anhydrotetracycline hydrochloride (ATC;CAS 13803-65-1) is an effector molecule utilized in tetracycline-controlled gene expression systems, modulating the DNA-binding activity of tetracycline repressor protein (TetR) and its engineered variant reverse TetR (revTetR). TetR binds to operator DNA sequences, inhibiting transcription. ATC binding induces TetR conformational changes, dissociating it from operator DNA, enabling gene expression. Conversely, ATC acts as a corepressor in revTetR systems, enhancing its DNA-binding inhibition. ATC displays approximately 35-fold greater affinity towards TetR compared to tetracycline, with an IC50 near 0.4 μM, employed in inducible gene expression studies in biological research contexts.

Applications |
Anhydrotetracycline was much more effective than tetracycline in inactivating transcriptional transactivator (tTA), and completely abolished tTA mediated luciferase activity at concentrations as low as 3 ng/ml. More importantly, the concentration at which the prolonged presence of anhydrotetracycline began to affect the growth rate of HeLa cells in culture (> 3 μg/ml) was more than thousand fold above the effective concentration. In addition, like tetracycline, anhydrotetracycline was well suited to attenuate gene expression at intermediate levels of induction. These properties together with the high functional stability of anhydrotetracycline in cell culture made anhydrotetracycline a most attractive alternative effector for tetracycline-controlled gene expression in higher eukaryotic systems. |
