Despite extensive investigations, approximately 50% of cases remain idiopathic, underscoring the intricate nature of potential pathogenic mechanisms. Quercetin (QUE), a prevalent flavonoid compound, exhibits potential in the therapeutic modulation of RPL by influencing endocrine, coagulation, oxidative stress, inflammation, and immune responses. This review aims to elucidate the potential role of QUE in RPL, explore its molecular mechanisms, and delineate its therapeutic significance. Herein, we synthesize existing evidence on the impact of QUE in RPL, particularly in traditional Chinese medicine, accentuating areas necessitating further exploration. QUE demonstrates regulatory prowess over RPL by modulating endocrine functions, encompassing thyroid functionality, diabetes, polycystic ovary syndrome, and luteal phase defects. It exhibits anti-inflammatory and antioxidant properties, influences coagulation functions, and affects immune cells such as T cells, T helper cells, macrophages, and natural killer cells. QUE also interacts with maternal-fetal interface cells, including myeloid-derived suppressor cells, stromal cells, and extravillous trophoblast cells, highlighting its multifaceted role in the modulation of RPL. Despite promising preclinical data, clinical trials directly targeting RPL remain limited. We emphasize the need for rigorous human studies to validate QUE's efficacy and safety in pregnancy. By elucidating the mechanistic underpinnings of QUE in treating RPL, this research may contribute to developing targeted interventions for RPL and other adverse pregnancy conditions, ultimately ameliorating reproductive health and well-being for affected individuals and families.","PeriodicalId":520606,"journal":{"name":"Drug discoveries & therapeutics","volume":" ","pages":"148-159"},"PeriodicalIF":0.0,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144532765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, data on the safety of biologics in a broader population are limited. This study aims to evaluate abortion-related adverse events (AEs) associated with adalimumab, etanercept, ustekinumab, and dupilumab, using data from the FDA Adverse Event Reporting System (FAERS) database. A disproportionality analysis was performed using the Reporting Odds Ratio (ROR) and Bayesian Confidence Propagation Neural Network (BCPNN) to identify signals of abortion-related AEs. The time-to-onset profiles were assessed by analyzing the description and Weibull shape parameters (WSPs) for these events. Sensitivity analyses were also conducted, including drug-drug interaction studies, logistic regression, and a similar retrospective analysis using data from the Japanese Adverse Drug Event Report (JADER) database. Disproportionality analysis revealed specific signals for abortion-related AEs associated with adalimumab, etanercept, and ustekinumab. The drug-drug interaction analysis indicated that these biologics, particularly without methotrexate or prednisolone, increase the risk of abortion-related AEs. Logistic regression identified several factors influencing outcomes. The time-to-onset analysis revealed that dupilumab had an earlier onset of 62.5 days, while etanercept had a later onset at 184 days. WSPs analysis revealed that signals for adalimumab, ustekinumab, and dupilumab exhibited early failure-type features, indicating a decreasing risk of abortion-related AEs over time. In conclusion, adalimumab, etanercept, and ustekinumab are associated with an increased risk of abortion-related adverse pregnancy outcomes, though the signals remain relatively weak. Further large-scale studies are needed to provide more definitive evidence.","PeriodicalId":520606,"journal":{"name":"Drug discoveries & therapeutics","volume":" ","pages":"160-173"},"PeriodicalIF":0.0,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144532764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We found that phosphate functionalization promotes faster internalization by granulocytes-immune cells functionally similar to mammalian neutrophils-highlighting a trade-off between antifungal activity and immune uptake. In parallel, phosphate-functionalized NGs exhibited prolonged circulation, more consistent biodistribution patterns, and reduced batch variability compared to unmodified NGs. These features contributed to superior and more reproducible in vivo antifungal efficacy when delivering itraconazole. Importantly, the biodistribution profiles observed in silkworms aligned well with previous mammalian data, further validating silkworms as an efficient, cost-effective model for early-stage evaluation of nanocarrier systems.

Although hormone therapy remains the most effective treatment, its long-term use is associated with significant risks, prompting interest in alternative options. Kampo medicine, a traditional Japanese system derived from Chinese herbal medicine, has gained renewed attention as a complementary and personalized therapeutic approach to menopausal health. This review aims to systematically summarize the current application and clinical evidence of Kampo medicine in the management of menopausal symptoms across multiple domains, including vasomotor, neuropsychiatric, musculoskeletal, skeletal, and genitourinary systems. Furthermore, the review seeks to further validate its efficacy through the mechanistic actions of its key ingredients. While the therapeutic effects of Kampo medicine on hot flashes have been inconsistent, it has demonstrated significant efficacy in improving emotional disturbances, sleep disorders, and somatic symptoms, particularly among individuals whose conditions are not driven solely by hormonal imbalances. In the management of osteoporosis, the integration of Kampo medicine with conventional Western treatments not only enhances overall therapeutic outcomes but also contributes to the reduction of adverse effects. One limitation of current research is the lack of randomized controlled trials (RCTs) evaluating the efficacy of Kampo medicine in managing Genitourinary Syndrome of Menopause (GSM), highlighting the need for further investigation in this area. The integration of Kampo medicine into menopausal symptom management may contribute to a more holistic, patient-centered approach that offers both traditional and Western medical options. This integrative model has the potential to support shared decision-making and improve personalized care for menopausal women.","PeriodicalId":520606,"journal":{"name":"Drug discoveries & therapeutics","volume":" ","pages":"136-147"},"PeriodicalIF":0.0,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144510306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On May 16, 2025, the FDA granted its first clearance to the Lumipulse G blood test, which utilizes the plasma pTau217/Aβ1-42 ratio, for the diagnosis of amyloid plaques in symptomatic patients age 55 or older. In clinical validation, concordance rates with amyloid PET brain scans/the results of cerebrospinal fluid biomarker detection were 91.7% (positive) and 97.3% (negative).

This study focused on mast cells involved in inflammation and examined the expression of photoreceptors and their effects on degranulation in mast cells. Photoreceptors expressed in two mast cell cultures (P-815 and RBL-2H3) were examined by RT-PCR and western blotting to demonstrate that OPN3 was expressed in RBL-2H3 cells. Next, the effect of visible light exposure on degranulation was evaluated by measuring β-hexosaminidase activity in the culture medium. The results show that β-hexosaminidase release was most strongly induced at wavelengths of ~460 nm, which corresponds to the absorption peak of OPN3. In addition, suppression of OPN3 expression by siRNA reduced β-hexosaminidase release at 460 nm. These results suggest that OPN3 expressed in mast cells mediates degranulation in skin inflammation that occurs upon exposure to intense light.","PeriodicalId":520606,"journal":{"name":"Drug discoveries & therapeutics","volume":" ","pages":"184-188"},"PeriodicalIF":0.0,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144510307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, targeting PLpro has emerged as an appealing therapeutic strategy against SARS-CoV-2 infection. Despite considerable efforts in the development of PLpro inhibitors, there is currently no drug available on the market that specifically targets PLpro. Improving drug screening strategies and identifying additional candidate compounds could significantly contribute to the advancement of antiviral agents targeting PLpro. To address this pressing issue, our present study has developed a highly efficient compound screening strategy based on a supervised machine learning approach. Integrated with further molecular simulation approaches such as molecular docking, molecular dynamics simulations, and quantum chemical calculations, we have identified seven compounds with potent inhibitory activity against PLpro. Notably, two of these compounds exhibited superior activity compared to Jun12682, which is currently considered the best-performing inhibitor against PLpro. Furthermore, some crucial residues in SARS-CoV-2 PLpro were recognized as favorable contributors to the binding with inhibitor, which would provide valuable insights for the development of more potent and highly selective SARS-CoV-2 PLpro inhibitors. The compound screening strategy and potential PLpro inhibitor candidates revealed in the present study would hold promise for advancing the development of antiviral drugs targeting SARS-CoV-2 and its variants.","PeriodicalId":520606,"journal":{"name":"Drug discoveries & therapeutics","volume":" ","pages":"189-199"},"PeriodicalIF":0.0,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144510304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the mechanisms and adaptive functions of these songs are well studied, knowledge about how songs develop within a generation is relatively scarce. Our previous work demonstrated a stable peak frequency at 5.7 kHz in the calling songs recorded from mature adult male crickets (Gryllus bimaculatus). In the present study, we monitored changes in the frequency component over time from the sexual maturity stage (early adult stage). We recorded 300 calling songs from a pool of 122 adults. The peak frequency distribution was lower and unstable (i.e., greater coefficient of variance) in the early adult stage. The mean peak frequency was 4.9 kHz on day 3, but gradually converged to 5.8 kHz over the 2-week adult stage. Immature adult males (emitting immature songs) produced an appropriately tuned song with a peak frequency of 5.8 kHz in an environment of 80% helium and 20% oxygen. These results suggest that the frequency component of the calling song is acquired during the early to mid-adult stage, and may be related to sexual maturation in males. Findings from the helium substitution experiment revealed that physical resistance from surrounding gas molecules negatively affect the stability of male singing, and that muscle development and forewing hardening may contribute to the maturation of singing, suggesting that females may adaptively select sexually mature males based on song traits.","PeriodicalId":520606,"journal":{"name":"Drug discoveries & therapeutics","volume":" ","pages":"204-209"},"PeriodicalIF":3.1,"publicationDate":"2022-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40356653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
