General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

About Packaging | 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial. 2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial. 3. Try to avoid loss or contamination during the experiment. |

Transforming growth factor (TGF)-β signaling facilitates tumor growth and metastasis in advanced cancer. Use of inhibitors of TGF-β signaling may thus be a novel strategy for the treatment of patients with such cancer. A-77-01 is a close analogue of A-83-01 and has a very similar biological profile of A-83-01. A-83-01 is found to decompose to A-77-01 under certain circumstances and A-77-01 is likely an active component or metabolite of its prodrug A-83-01.
In vitro: A-77-01 and A-83–01 almost completely inhibited the transcriptional activation induced by the constitutively active TGF-β type I receptor (ALK5-TD). A-77-01 and A-83-01 were five to 10 times more potent than the ALK-5 inhibitor SB-431542. In contrast, treatment with 1 μM A-77-01 or 1 μM A-83-01 had no effects on BMP-induced transcriptional activity. However, A-83-01, but not A-77–01, weakly suppressed the transcriptional activity induced by BMP4 at concentrations above 3 μM. A-83-01 and A-77-01 had weak effects on osmotic shock-induced p38 MAPK activity only at high concentrations. A-83-01 and A-77-01 restored the expression of E-cadherin and repressed that of fibronectin and N-cadherin more efficiently than SB-431542 [1].
In vivo: No animal in-vivo data available currently.
Clinical trial: A-77-01 is currently in the preclinical developlent stage and no clinical data are available.
