research Preliminary pharmacokinetics and metabolism of novel non-steroidal antiandrogens in the rat: Relation of their systemic activity to the formation of a common metabolite
Two non-steroidal antiandrogens, RU 58841 and RU 56187, form a common metabolite at different rates, which may influence their effects; RU 56187 could be used for prostate cancer treatment and RU 58841 for acne treatment.
research New steps forward in the neuroactive steroid field
Neuroactive steroids could become safe, effective treatments with more understanding of their complex brain actions and metabolism.
research Neuroactive steroid levels and psychiatric and andrological features in post-finasteride patients
Post-finasteride patients show changed neuroactive steroid levels, possibly causing erectile dysfunction and depression.
research Aromatase-independent testosterone conversion into estrogenic steroids is inhibited by a 5α-reductase inhibitor
Combining 5α-reductase and aromatase inhibitors may better reduce estrogen levels.
research Patients treated for male pattern hair with finasteride show, after discontinuation of the drug, altered levels of neuroactive steroids in cerebrospinal fluid and plasma
Finasteride affects brain and blood steroids, causing lasting sexual and emotional side effects.
research Plasma levels of C19 steroid glucuronides in pre-menopausal women with non-classical congenital adrenal hyperplasia
Women with non-classical congenital adrenal hyperplasia have higher levels of certain steroids, which can be reduced by treatment.
research Corrigendum to “Patients treated for male pattern hair loss with finasteride show, after discontinuation of the drug, altered levels of neuroactive steroids in cerebrospinal fluid and plasma” [J. Steroid Biochem. Mol. Biol. 146 (2015) 74–79]
Stopping finasteride for male pattern hair loss changes neuroactive steroid levels in the brain and blood.
research Intracrine androgen biosynthesis, metabolism and action revisited
The document concludes that blocking the internal pathways that create androgens might help treat cancers that depend on sex hormones.
research Adverse health effects of androgen use
Using anabolic androgenic steroids can cause serious, lasting health problems in many parts of the body.
research The significance of CYP11A1 expression in skin physiology and pathology
CYP11A1 is crucial for skin health and disease by producing important steroids.
research Which chemicals should be grouped together for mixture risk assessments of male reproductive disorders?
Group a wide range of chemicals, not just phthalates, for assessing risks to male reproductive health.
research Pharmacotherapy for Keloids and Hypertrophic Scars
Combination pharmacotherapy is generally more effective for treating keloids and hypertrophic scars.
research Androgen binding profiles of two distinct nuclear androgen receptors in Atlantic croaker (Micropogonias undulatus)
Different types of androgens bind differently to two receptors, AR1 and AR2, in Atlantic croaker's brain and ovarian tissues, suggesting these receptors may control different androgen actions in fish.
research Investigation of intermolecular interactions in finasteride drug crystals in view of X-ray and Hirshfeld surface analysis
Finasteride crystals are held together by hydrogen bonds and weak interactions, forming synthon pseudopolymorphs.
research Evaluation of a novel dry eye model induced by oral administration of finasteride
Finasteride causes reduced tear flow and severe eye inflammation.
research In vivo and in vitro effect of novel 4,16-pregnadiene-6,20-dione derivatives, as 5α-reductase inhibitors

research 5α-reduction of epitestosterone is catalysed by human SRD5A1 and SRD5A2 and increases androgen receptor transactivation
5α-reductases increase epitestosterone's effect on androgen receptors.
research Steroidogenesis inhibitors alter but do not eliminate androgen synthesis mechanisms during progression to castration-resistance in LNCaP prostate xenografts
Steroidogenesis inhibitors change but don't stop androgen production in prostate cancer.
