Gestronol

Gestronol, also known as gestonorone, as well as 17α-hydroxy-19-norprogesterone or 17α-hydroxy-19-norpregn-4-ene-3,20-dione, is a progestin of the 19-norprogesterone and 17α-hydroxyprogesterone groups which was never marketed. The C17α caproate ester of gestronol, gestonorone caproate, in contrast, has been marketed.

Gestronol (BANTooltip British Approved Name), also known as gestonorone, as well as 17α-hydroxy-19-norprogesterone or 17α-hydroxy-19-norpregn-4-ene-3,20-dione, is a progestin of the 19-norprogesterone and 17α-hydroxyprogesterone groups which was never marketed.123 The C17α caproate ester of gestronol, gestonorone caproate (gestronol hexanoate), in contrast, has been marketed.123

Gestronol shows relatively low affinity for the progesterone receptor, only about 12.5% of that of progesterone and about 2.5% of that of 19-norprogesterone in one assay.4 On the other hand, gestronol had far higher affinity than 17α-hydroxyprogesterone, which showed less than 0.1% of the affinity of progesterone for the progesterone receptor.4
