This study suggests that while hair analysis using GC-MS is a sensitive method for detecting cocaine ingestion, it may not reliably indicate the amount, timing, or duration of drug use due to interindividual variability and multiple incorporation mechanisms.

This study reports that hair analysis could potentially monitor metformin use in diabetic patients, suggesting a possible correlation between daily dose and concentration in dark hair but not in light hair.

This study found that a single application of 'Lye' or 'No-Lye' chemical straighteners significantly reduced drug concentrations in hair samples from both drug-fortified standards and authentic drug users.

Homemade hair treatments can significantly lower drug levels in hair, possibly causing false-negative drug tests.

This study found that in vitro heat straightening of hair reduced THC and cocaine concentrations but increased CBN and BZE levels, suggesting heat conversion of these substances.

This study found that Minoxidil can interfere with hair drug analysis for cocaine by producing peaks that obscure the detection of cocaine and its metabolites in chromatograms.

In this study, ALR was found to enhance both the proliferation and osteogenic differentiation of mouse bone marrow mesenchymal stem cells, potentially through specific signaling pathways.

This study found that certain molecular quantum descriptors can be directly correlated with the biological activity of benzo[c]quinolizin-3-ones, potentially aiding in the identification and design of active compounds.

A new antiandrogen compound was made and its detailed three-dimensional shape was described.

This study identified novel compounds as selective inhibitors of the type 1 isoenzyme of 5α-reductase, displaying promising potential for treating DHT-dependent disorders such as acne and androgenic alopecia.

This study demonstrated that benzothiazepines, such as diltiazem and JTV-519, exert anxiolytic-like effects through allopregnanolone biosynthesis in mice, similar to carbamazepine.

This study reports the crystal structure of C28H32O5, revealing its monoclinic symmetry, unit-cell dimensions, and molecular conformation.

In this study, 4-(4-(phenylaminocarbonyl)benzoyl) benzoic acid exhibited the strongest inhibitory activity against the human type 2 steroid 5α-reductase isozyme among the compounds tested.

In this study, novel substituted benzoyl benzoic acids and phenylacetic acids were potent and selective inhibitors of human steroid 5alpha-reductase type 2, with one compound showing promising bioavailability in rats for potential clinical evaluation.

This study found that octahydrobenzo[c]quinolizin-3-one derivatives, particularly compound 3, were potent and selective inhibitors of the enzyme 5α-reductase type 1.

This study explored how modifying the 8-substituent of 8-bromobenzoquinolinone affects its selectivity in inhibiting both 5 alpha-reductase isozymes in the scalp.

This synthesis report details the successful development of a C-14 labeled isotopomer of LY300502, a 5α-reductase inhibitor, through a multi-step radiochemical process.

This study found that among the tested analogs, compound 4e was the most effective in inhibiting wax esters in vivo in the Golden Syrian hamster ear model.

This study discovered that the disposition of LY191704 enantiomers in rats and dogs is both stereoselective and species specific.

This study reported that the compound (1R, 2S)-4-(2-cyano-cyclohexyl-oxy)-2-trifluoromethyl-benzonitrile effectively stimulated hair growth in mice and reduced sebum production in hamsters.

RY-023, a specific drug, can improve early stage memory learning without affecting general activity in rats, but it's less effective for later learning stages and doesn't impact memory recall.

In this study, researchers successfully synthesized a rigid 3a-arylhexahydropentalene-1,6-dione from the easily accessible starting material cyclopent-2-en-1-one, highlighting a structural motif common in natural products and pharmaceuticals.

This study identified potent dual inhibitors of 5α-reductases 1 and 2 that may aid in designing new drugs for related diseases.

This study describes the molecular conformation and intermolecular interactions in the crystalline structure of the compound C24H31BrO4.

This research article focuses on nonsteroidal inhibitors of human type I steroid 5-alpha-reductase but reports no new results.

The authors concluded that newly synthesized N-acyl-L-tryptophanyl-isoleucine amides showed high anxiolytic activity in animal models, comparable to diazepam, through interaction with the TSPO receptor.

This study reported that derivatization with 5-butylpicolinic acid improved the sensitivity for detecting testosterone and DHT in saliva using LC-ESI-MS/MS, with minimal interference from the saliva matrix.

This study found that midazolam, unlike clonazepam, increased neurosteroid levels and affected synaptic inhibition and plasticity in rat hippocampal neurons, suggesting unique actions via dual receptor activation.

This study developed a new competitive 5alpha-reductase inhibitor with an IC(50) of 0.84 microM using a novel chemical structure.
