Common Name25,27-Dihydro-4,7-didehydro-7-deoxyphysalin A
Description25,27-Dihydro-4,7-didehydro-7-deoxyphysalin A, also known as hycanthon or etrenol, belongs to the class of organic compounds known as physalins and derivatives. These are steroidal constituents of Physalis plants which possess an unusual 13,14-seco-16,24-cyclo-steroidal ring skeleton (where the bond that is normally present between the 13 and 14 positions in other steroids is broken while a new bond between positions 16 and 24 is formed). 25,27-Dihydro-4,7-didehydro-7-deoxyphysalin A is an extremely weak basic (essentially neutral) compound (based on its pKa).
