Biological Activity

A-83-01, an inhibitor of TGF-β type I receptor, increased the expression of Myf5 and MyoD, and enhanced myotube formation.The targeting efficacy of single intravenous injections of F-SL combined with A-83-01 was evaluated by measurement of the biodistribution and the antitumor effect in mice bearing murine lung carcinoma M109. A-83-01 temporarily changed the tumor vasculature around 3 h post injection. A-83-01 induced 1.7-fold higher compound accumulation of F-SL in the tumor than liposome alone at 24 h post injection.

*The compound is unstable in solutions, freshly prepared is recommended

Cell Lines SKBR3 cells
Concentrations 1 μM 
Incubation Time 16 h
Results As shown in Fig. 6c that A83-01 alone reduced approximately 17% cell migration of JIMT1 and trastuzumab alone inhibited 20% cell migration, while in combination of A83-01 and trastuzumab synergistically inhibited JIMT1 cell migration up to 90%.

Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
