research Improving the treatment of bacterial infections caused by multidrug-resistant bacteria through drug repositioning
This review examines drug repositioning as a strategy for combating bacterial infections, highlighting its potential to address multidrug-resistant strains and antibiotic resistance by analyzing safety profiles, synergistic combinations, and promising results for drugs initially used for other conditions.
research Cloning, expression and characterization of rhesus macaque types 1 and 2 5alpha-Reductase: evidence for mechanism-Based inhibition by finasteride
This study concludes that rhesus macaques are a suitable model for testing the pharmacological properties of finasteride and other 5aR inhibitors, due to their biochemical similarity to humans.
research Adverse effect profile with low-dose methotrexate therapy in patients suffering with rheumatic diseases
This study of South Indian patients with autoimmune rheumatic diseases using low-dose methotrexate reported that while mild adverse effects such as hair loss and nausea were common, serious events like cytopenia were less frequent, and folic acid supplementation significantly reduced their prevalence.
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.
This study found that GI198745 acts as a time-dependent inhibitor of rat 5α-reductase type 2 but a rapid-equilibrium inhibitor of type 1, potentially making it more effective than finasteride in preventing rat prostate growth.
research Inhibitory effects of the ATP-sensitive potassium channel openers cromakalim, pinacidil and minoxidil on the carbachol–response curve in porcine detrusor muscle
This study found that cromakalim and pinacidil significantly inhibited porcine detrusor muscle contractions, suggesting these ATP-sensitive potassium channel openers may have potential in treating certain bladder diseases.
research Suppression of mammary tumorigenesis in transgenic mice by the RXR-selective retinoid, LGD1069.
This study found that the retinoid LGD1069 suppressed mammary tumorigenesis in a mouse model without observable toxicity, while TTNPB showed modest effects but was associated with significant toxicity.
research In Patients With Acne Vulgaris, How Do Standard Acne Treatments Combined With Adjunct Microbiome-Targeted Therapies Compare to Standard Acne Treatments Alone in Affecting Clinical Outcomes?
This research review identified improved outcomes in acne treatment when oral probiotics or topical probiotic-derived formulations were added to standard therapies, with probiotics reducing acne severity and enhancing safety and tolerability compared to treatments such as 2.5% Benzoyl Peroxide and Doxycycline.
research Determination of rat 5α-reductase type 1 isozyme activity and its inhibition by novel steroidal oxazolines
This study found that novel compounds moderately inhibited 5α-reductase type 1 activity compared to finasteride, offering valuable data on structure-activity relationships.
research Development and optimization of levofloxacin in-situ emulgel to manage ocular bacterial infections
In this study, researchers developed an in-situ gel formulation of antibacterial Levofloxacin for the eye, which showed prolonged drug release, increased residence time, and effective antibacterial action, suggesting it may be a safe and effective ocular delivery system for antibiotics.
research Targeting telomeric RNA quadruplexes with natural metabolites to prevent cancer
research Enzalutamide/finasteride/goserelin/zoledronic-acid
research Finasteride
research MK-386, an Inhibitor of 5α-Reductase Type 1, Reduces Dihydrotestosterone Concentrations in Serum and Sebum without Affecting Dihydrotestosterone Concentrations in Semen1
This study found that MK-386 selectively suppressed sebum DHT levels in a dose-dependent manner, suggesting potential use for treating acne.
research Tribuloside acts on the PDE/cAMP/PKA pathway to enhance melanogenesis, melanocyte dendricity and melanosome transport
This study found that tribuloside, a flavonoid from Tribulus terrestris L., enhances melanin production in human melanocytes, zebrafish, and human skin samples without causing toxicity, potentially through inhibiting PDE to increase cAMP levels and promote the melanin biosynthesis pathway.
research 1370 MTORC1 activity is increased in the skin of acne patients and is suppressed with isotretinoin treatment
This study found that isotretinoin decreases mTORC1 signaling in acne skin, suggesting that mTOR inhibitors may have potential therapeutic benefits for acne patients.
research [Oral treatment of severe psoriasis with a new aromatic retinoid (Ro 10-9359) (author's transl)].
