Synthesis of Aryl Propionamide Scaffold Containing a Pentafluorosulfanyl Moiety as SARMs
Keyword(s):
The pentafluorosulfane (SF5) group, as a more electronegative bioisostere than the trifluoromethyl (CF3) group, has been gaining greater attention and increasingly reported usage in medicinal chemistry. Ostarine is the selective androgen receptor modulators (SARMs) containing a CF3 group in clinical trial III. In this study, 21 ostarine derivatives for replacing the CF3 group with SF5 substituents were synthesized. Some SF5-derivatives showed androgen receptor (AR) agonistic activities in vitro. The results pointed to the potential of using this scaffold to develop new AR agonists.
