Substituted androst-4-ene diones
The disclosure relates to novel C4 and C6 substituted androst-4-ene diones as well as andros-1,4-diene diones and derivatives thereof, their process of preparation, pharmaceutical compounds containing them, and the use of said compounds for the treatment of hormone-related disorders in mammals. This includes hormone-dependent cancers, particularly those caused by elevated levels of estrogen and its intermediates. These compounds can also be used in the treatment of other hormone-related disorders, including benign prostatic hyperplasia, cardiovascular disease, and neurodegenerative disorders.
