research Pharmacokinetic parameters and mechanisms of inhibition of rat type 1 and 2 steroid 5α-reductases: determinants for different in vivo activities of GI198745 and finasteride in the rat 3 3Abbreviations: r5AR1, rat 5α-reductase 1; r5AR2, rat 5α-reductase 2; and DHT, dihydrotestosterone.
GI198745 is more potent and longer-lasting than finasteride, potentially better for treating hair loss.
research GC-MS determination of steroids related to androgen biosynthesis in human hair with pentafluorophenyldimethylsilyl–trimethylsilyl derivatisation
The method accurately measures certain steroids in human hair, showing different levels in males and females.
research Solubilization and Solid‐State Characterization of a Poorly Soluble 5‐α Reductase Inhibitor
GI197111X is best dissolved in Capmul MCM for trials.
research The influence of selected steroid hormones on the physicochemical behaviour of DPPC liposomes
Steroid hormones change the size, charge, and stability of DPPC liposomes.
research Effect of MK-386, a novel inhibitor of type 1 5 alpha-reductase, alone and in combination with finasteride, on serum dihydrotestosterone concentrations in men
research Allopregnanolone promotes proliferation and differential gene expression in human glioblastoma cells
Allopregnanolone increases growth and changes gene activity in human brain cancer cells.
research [Analysis of steroids and binding proteins in the blood of women with androgenetic alopecia].
Women with androgenetic alopecia have normal levels of most blood steroids and binding proteins, but higher dehydroepiandrosterone. Some also have low "sex hormone-binding globulin" and "corticosteroide-binding globulin" capacity, and high "free androgen index" and "free cortisol index". Diane treatment can normalize these levels and improve hair conditions.
research Discovery of Natural Steroid 5 Alpha-Reductase Inhibitors
Natural herbal compounds might treat certain medical conditions by reducing DHT levels, but more research is needed to confirm their effectiveness and safety.
research Synthesis and biological evaluation of novel unsaturated carboxysteroids as human 5α-reductase inhibitors: A legitimate approach
New steroid compounds effectively inhibit 5α-reductase and may treat hair loss.
research Attenuation of 5α-reductase-mediated progesterone metabolism promotes differentiation of human endometrial stromal cells for the establishment of pregnancy
Reducing 5α-reductase activity helps endometrial cells differentiate, aiding pregnancy.
research Effects of Dehydroepiandrosterone Therapy on Pubic Hair Growth and Psychological Well-Being in Adolescent Girls and Young Women with Central Adrenal Insufficiency: A Double-Blind, Randomized, Placebo-Controlled Phase III Trial
DHEA therapy improves pubic hair growth and psychological well-being in young females with central adrenal insufficiency.
research Novel Lead Generation through Hypothetical Pharmacophore Three-Dimensional Database Searching: Discovery of Isoflavonoids as Nonsteroidal Inhibitors of Rat 5α-Reductase
Researchers found new potential but less potent rat enzyme inhibitors using a 3D model.
research Local stimulation of sebaceous gland activity by the topical administration of dehydroepiandrosterone
Topical DHEA safely increases skin oil production.
research Synthesis and Evaluation of 2‘-Substituted 4-(4‘-Carboxy- or 4‘-carboxymethylbenzylidene)-N-acylpiperidines: Highly Potent and in Vivo Active Steroid 5α-Reductase Type 2 Inhibitors
Compounds 15, 20, and 25 are strong inhibitors of human steroid 5α-reductase type 2.
research Effect of finasteride on human testicular steroidogenesis.
research Three-Month Treatment With a Long-Acting Gonadotropin-Releasing Hormone Agonist of Patients With Benign Prostatic Hyperplasia: Effects on Tissue Androgen Concentration, 5α-Reductase Activity and Androgen Receptor Content*
A three-month treatment with a GnRH agonist significantly lowered androgen levels and 5α-reductase activity in men with benign prostatic hyperplasia.
research A role for steroid 5 alpha-reductase 1 in vascular remodeling during endometrial decidualization
The enzyme 5α-reductase type 1 is important for blood vessel development and fertility in the uterus.
research DUTASTERIDE AS AN EFFECTIVE TREATMENT IN ANDROGENETIC ALOPECIA – A LITERATURE REVIEW
Dutasteride is more effective than finasteride for hair loss, but more research is needed on safety and dosing.
research Synthesis of phenanthridin-3-one derivatives: Non-steroidal inhibitors of steroid 5-α-reductase
New chemicals were made that can block an enzyme linked to hair loss, prostate growth, and acne.
research Assessment of diagnostic competence of plasmatic androgens on polycystic ovary syndrome based on receiver operator characteristic curves
Free Testosterone Index, bioavailable testosterone, and androstenedione are the most accurate for diagnosing excess male hormones in PCOS.
research ISID1116 – Novel androgen receptor degrader for androgenetic alopecia (AGA) application
research Dehydroepiandrosterone- and glucose-6-phosphate-dehydrogenases in the hair cycle of the rat
research Preparation of3H-labelled testosterone metabolites
The conclusion is that tritium-labeled testosterone metabolites can be made and are better converted into dihydrotestosterone in skin cells than in prostate tissue.
research Pharmacology of antiandrogens
Antiandrogens affect androgen-dependent body functions and are used for various medical conditions, with some risks like fetus feminization, but new forms like 17α-propylmesterolone show promise for acne without systemic effects.
research Higher Levels of Steroidogenic Acute Regulatory Protein and Type I 3β-Hydroxysteroid Dehydrogenase in the Scalp of Men with Androgenetic Alopecia
Men with baldness have higher levels of specific proteins, suggesting local hormone production may play a role in hair loss.
research Novel C-6 substituted and unsubstituted pregnane derivatives as 5α-reductase inhibitors and their effect on hamster flank organs diameter size
Certain compounds reduced hamster flank organ size by inhibiting 5α-reductase, like finasteride, without affecting androgen receptors.
