4-alkyl- and 3,4-dialkyl-1,2,3,4-tetrahydro-8-pyridono [5,6-g]quinolines: Potent, nonsteroidal androgen receptor agonists

A series of human androgen receptor (hAR) agonists based on 4-alkyl-: 4,4-d ialkyl-; and 3,4-dialkyl-1,2,3,4-tetrahydro-8-pyridono [5,6-g] quinoline wa s synthesized and evaluated In competitive receptor binding assays and an a ndrogen receptor cotransfection assay in a mammalian cell background. A num ber of compounds in this series demonstrated activity equal to or better th an dihydrotestosterone in both assays and represent a novel class of compou nds for use in androgen replacement therapy.
