v · d · e Relative affinities (%) of levonorgestrel and metabolites
Compound PR AR ER GR MR SHBG CBG
Levonorgestrel 150–162 34a, 45 0 1–8 17–75 50 0
5α-Dihydrolevonorgestrel 50 38a 0 ? ? ? ?
3α,5α-Tetrahydrolevonorgestrel ? ? 0.4 ? ? ? ?
3β,5α-Tetrahydrolevonorgestrel ? ? 2.4 ? ? ? ?
Notes: Values are percentages (%). Reference ligands (100%) were promegestone for the PR, metribolone (a = mibolerone) for the AR, E2 for the ER, DEXA for the GR, aldosterone for the MR, DHT for SHBG, and cortisol for CBG. Sources: [1][2][3][4]
