Binimetinib, in combination with encorafenib, has received marketing approval in several jurisdictions for the treatment of patients with BRAF V600E or V600K mutant melanoma. The absorption, distribution, metabolism, and excretion of binimetinib were evaluated by administering a carbon 14-labeled binimetinib 45 mg dose (containing 40 μCi of radiolabeled material) to 6 healthy male participants. A total of 62.3% of the radioactivity was eliminated in the feces, while 31.4% was eliminated in the urine. The overall recovery of radioactivity in the excreta for all 6 participants was 93.6% (3.27%), indicating that good mass balance was achieved. The total percentage of the dose in the excreta of all metabolites containing the N-demethylation clearance of binimetinib by CYP1A2 and CYP2C19 was approximately 17.8%. The contribution of direct glucuronidation to the clearance of binimetinib was estimated to be 61.2% and represented the majority of the clearance. Additionally, excretion of unchanged binimetinib into the urine was estimated to have contributed 6.9% to the overall clearance.

To counteract dopamine oxidation, newly synthesized dopamine is quickly transported into vesicles via vesicular monoamine transporter 2 (VMAT2) for storage. VMAT2 expression is reduced in patients with PD, and studies have shown increased accumulation of dopamine oxidation byproducts and α-synuclein in animals with low VMAT2 expression. Conversely, animals that overexpress VMAT2 show better protection for dopamine neurons. Based on these findings, this study used histone deacetylase inhibitors (HDACi) to increase VMAT2 expression, reduce dopamine-induced oxidative stress, and evaluate the resulting behavioral improvements in a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD animal model. LMK-235 not only increased VMAT2 expression at various concentrations in the SH-SY5Y cell line differentiated into dopaminergic cells but also demonstrated effective cytoprotective properties in several toxicity assays. It significantly raised VMAT2 expression in both the striatum and the ventral tegmental area of an MPTP-induced PD model, supporting its role in reversing behavioral abnormalities linked to PD. In addition to these results, coadministration of LMK-235 with L-DOPA, a standard therapy for PD, restored typical behavioral patterns, highlighting the potential of HDACi in alleviating PD symptoms. The expression of VMAT2 induced by LMK-235, an inhibitor of Class IIa histone deacetylases primarily found in the nervous system, aids in sequestering dopamine into vesicles, potentially enhancing cell survival by inhibiting dopamine oxidation. Additionally, upregulation of VMAT2 has been shown to offer effective protection against MPTP-induced toxicity and significantly improve behavioral abnormalities associated with PD. Coadministration with L-DOPA produced the most notable improvement in behavioral outcomes. Altogether, these findings suggest that the overexpression of VMAT2 may offer a promising strategy for developing treatments for PD by mitigating dopaminergic neuron death resulting from dopamine oxidation.</p>","PeriodicalId":19948,"journal":{"name":"Pharmacology Research & Perspectives","volume":"13 1","pages":"e70057"},"PeriodicalIF":2.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11729409/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142979430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A scan of the clinical landscape of non-commercially sponsored repurposed medicines is routinely conducted by the NIHR Innovation Observatory (IO). This ongoing project involves a horizon scan of clinical trial registries and the IO's internal horizon scanning Medicines Innovation Database to identify potential candidate medicines used as monotherapy or in combination to treat new indications outside the scope of their licensed indication. In addition to making these data publicly available, the output also supports the NHS England Medicines Repurposing Programme.

The technologies were classified according to their characteristics and targeted therapeutic indications as well as revealing the least treated disease conditions.

It may be tempting to use methods of estimation that are easy to implement, however selecting an incorrect method may lead to biased estimates (under- or overestimation) and change the research outcomes, for example, incorrect result of two-sample test about means when comparing two populations or biased estimation of regression line. In this article, we consider the use of four methods: ignoring unmeasured observations, replacing unmeasured observations with a multiple of the limit, using a truncated normal distribution, and using a normal distribution with censored observations.

These recommendations should be incorporated into guidelines for good statistical practice. If the amount of observations outside of measurable range exceeds 40%, we advise not to use the data for any statistical analysis.

This study developed an A549 alveolar carcinoma spheroid model for cytotoxicity assessment and mechanistic evaluation of functionalized AuNPs. A549 spheroids were generated using an agarose micro-mold and were characterized (morphology, acid phosphatase activity, protein content) over 21 culturing days. The 72-h cytotoxicity of carboxyl-polyethylene glycol- (PCOOH-) and amine-polyethylene glycol- (PNH₂-) functionalized AuNPs against Day 7 spheroids was assessed by determining spheroid morphology, acid phosphatase activity, protein content, caspase-3/7 activity, and cell cycle kinetics. Spheroids remained stable over the experimental period. Although the A549 spheroids' volume increased while remaining viable over the culturing period, structural integrity decreased from Day 14 onwards. The PCOOH-AuNPs lacked cytotoxicity at a maximum concentration of 1.2 × 10¹² nanoparticles/mL with no prominent alteration to the cellular processes investigated, while the PNH₂-AuNPs (at a maximum of 4.5 × 10¹² nanoparticles/mL) displayed dose- and time-dependent cytotoxicity with associated loss of spheroid compactness, debris formation, DNA fragmentation, and a 75% reduction in acid phosphatase activity. Differentiation between cytotoxic and non-cytotoxic AuNPs was achieved, with preliminary elucidation of cytotoxicity endpoints. The PNH₂-AuNPs promote cytotoxicity by modulating cellular kinetics while destabilizing the spheroid ultrastructure.

A systematic search of PubMed, EMBASE, SCOPUS, and Web of Science was conducted following PRISMA-ScR guidelines. Eligible studies included in vitro, in vivo, and clinical investigations. Data on cancer types, pathways, assays, and outcomes were extracted and synthesized to identify trends and gaps. Of 588 screened studies, 23 met inclusion criteria, spanning cancer types such as breast, colorectal, lung, and brain cancers. ARI modulates key pathways like PI3K/AKT/mTOR and Wnt/β-catenin, induces apoptosis through mitochondrial dysfunction and ER stress, and overcomes drug resistance by inhibiting P-glycoprotein activity and expression. It exhibits tumor-suppressive effects in vivo and synergizes with chemotherapy and radiotherapy. Retrospective population studies suggest ARI's prolactin-sparing properties may reduce the risk of hormone-sensitive cancers such as breast and endometrial cancer compared to antipsychotics with stronger dopamine receptor blockade. Additionally, ARI's ability to target multiple Hallmarks of Cancer highlights its promise as a repurposed anticancer agent. However, current evidence is primarily preclinical and observational, with limited clinical validation.
