Biochem Pharmacol . 2019 Dec; 172:113781. PMID: 31884045
Anabolic-androgenic steroids (AAS) are testosterone derivatives developed for steroid-replacement and treatment of debilitating conditions. They are widely used by athletes in elite sports and bodybuilding due to their muscle-building and...

Abdelsamie A, Salah M, Siebenburger L, Merabet A, Scheuer C, Frotscher M, et al.
J Med Chem . 2019 Jul; 62(15):7289-7301. PMID: 31343176
Osteoporosis is predominantly treated with drugs that inhibit further bone resorption due to estrogen deficiency. Yet, osteoporosis drugs that not only inhibit bone resorption but also stimulate bone formation, such...

J Steroid Biochem Mol Biol . 2019 Jun; 192:105405. PMID: 31185280
Hormone replacement therapy is a viable option to protect bone from postmenopausal osteoporosis. Systemically elevated estrogen levels, however, are disadvantageous because of the risk of harmful side effects in other...

Eur J Med Chem . 2019 Jun; 178:93-107. PMID: 31176098
Estrogens are the major female sex steroid hormones, estradiol (E2) being the most potent form in humans. Disturbing the balance between E2 and its weakly active oxidized form estrone (E1)...

J Med Chem . 2019 Jan; 62(3):1362-1372. PMID: 30645111
Current therapies of steroid hormone-dependent diseases predominantly alter steroid hormone concentrations (or their actions) in plasma, in target and nontarget tissues alike, rather than in target organs only. Targeted therapy...
