BP-2 and BP-6 demonstrated micromolar-range antiproliferative activity against MDA-MB-231 cancer cells, with IC50 values of 8 and 4 µM, respectively, comparable to nocodazole (3 µM), and showed selective cytotoxicity over normal MCF-10A cells, with selectivity indices of approximately 3.3 and 8. In vitro analyses revealed that BP-2 and more notably BP-6 significantly inhibited cell proliferation in a time- and dose-dependent manner, disrupted microtubule organization through the downregulation of β-tubulin expression, and induced apoptosis, as evidenced by increased levels of Cleaved Caspase-3 and distinct apoptotic morphological changes. Among the tested compounds, BP-6 exhibited the most potent antiproliferative and proapoptotic activity, with an IC50 value close to that of NOC. Molecular docking supported these findings by showing strong binding affinities of BP-6 to both β-tubulin and Caspase-3, indicating a dual-targeted mechanism. Furthermore, molecular dynamics simulations confirmed the stable binding and dynamic integrity of BP-6 within both β-Tubulin and Caspase-3 targets, underscoring its potential as a robust candidate for anticancer drug development.","PeriodicalId":147,"journal":{"name":"ChemMedChem","volume":"20 17","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chemistry-europe.onlinelibrary.wiley.com/doi/epdf/10.1002/cmdc.202500320","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144726225","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}

However, there remain challenges, including complex chemical synthesis and linker screening. To address this, a proof-of-concept of a new modularized method by constructing DNA-PROTAC is presented by identifying the valid BRD4 and Sirt2 DNA-PROTACs. These findings may provide new approaches for linker design and ligand screening for PROTACs. Herein, a ligand modularization strategy is proposed that leverages the programmability of DNA to modulate the design and construction of PROTAC molecules to facilitate the programmatic discovery of new PROTAC molecules. The bromodomain-containing protein 4 (BRD4) is selected as a target for degradation to verify the effectiveness of DNA-PROTACs. The kinetics of BRD4 degradation were assessed by performing time-course experiments in HeLa cells. In addition, to evaluate the feasibility of the DNA-PROTAC strategy for degradation of other proteins, the silent mating type information regulation 2 homolog−2 (Sirt2) is selected as the degradation target. The design and synthesis procedures of BRD4 and Sirt2 DNA-PROTACs and their mechanisms of action, are systematically introduced, and the results may provide a new method for linker design and ligand screening of PROTACs.","PeriodicalId":147,"journal":{"name":"ChemMedChem","volume":"20 16","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144697208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It phosphorylates serine 2 of RNA polymerase II C-terminal domain, thereby promoting transcriptional elongation and 3'-end processing of replication-dependent histone genes. CDK11 also contributes to proper chromosome segregation during mitosis. As a key regulator of global pre-mRNA splicing, CDK11 activates the spliceosome, by phosphorylating Splicing Factor 3B Subunit 1, a core component of the U2 small nuclear ribonucleoprotein complex. Given the tight coupling between splicing, transcription, and cell proliferation, inhibition of CDK11 is hypothesized to impair both general transcription and cell cycle progression. CDK11 drives cancer cell proliferation, promotes HIV-1 mRNA 3'-end processing to enhance viral replication, and contributes to tau phosphorylation in Alzheimer's disease. Owing to itscentral role in key cellular processes and its dysregulation in various diseases, CDK11 has emerged as a compelling therapeutic target. This review provides a comprehensive overview of the biological functions and regulatory mechanisms of CDK11, discusses its role in cancer, viral, and neurodegenerative diseases, and highlights advances in the discovery and development of CDK11 inhibitors, including OTS964, which has expanded our understanding of the biological functions of CDK11 and its prospects as a cancer-specific vulnerability.","PeriodicalId":147,"journal":{"name":"ChemMedChem","volume":" ","pages":"e202500305"},"PeriodicalIF":3.4,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144582730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pyrazolopyrimidinones are fused nitrogen-containing heterocyclic systems which are a scaffold in several bioactive drugs and drug candidates. Here, a structure-activity relationship (SAR) study was performed where 23 substituted pyrazolo[1,5-α]pyrimidinones were screened for cytotoxicity against the GBM U-251 MG cell line and the noncancerous embryonic kidney HEK293 cell line to assess their potential as antiGBM agents capable of selectivity for cancer cells. Through analog synthesis of preliminary HIT compounds with varied structural substituents, a lead compound, 22, has been identified, which proved capable of inducing significant GBM cell death while having a marginal cytotoxicity against the noncancerous cells. The mode of cell death studies suggested that the structurally varied HIT compounds induced cell death through differential mechanisms including cell membrane permeabilization and mitochondria membrane depolarization-dependent mechanisms such as necrosis or apoptosis. The results highlight the potential of pyrazolo[1,5-α]pyrimidinones derivatives as a novel anti-GBM therapy, capable of selectively killing cancer cells. Furthermore, pyrazolo[1,5-α]pyrimidinones provide a scaffold for further development of selective GBM therapies.","PeriodicalId":147,"journal":{"name":"ChemMedChem","volume":" ","pages":"e202500337"},"PeriodicalIF":3.4,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144582731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compounds 6c (IC50 = 8.30 ± 0.33 μM) and 6b (IC50 = 14.0 ± 0.16 μM) exhibit promising inhibition of α-glucosidase in comparison to reference used (Acarbose, IC50 = 13.50 ± 0.32 μM). Five hybrids show better activity than precursor alkyne (IC50 = 19.57 ± 0.013 μM). The role of various covalent linkers between triazole and phenyl ring has been established using structure-activity relationship. The most probable mode of inhibition is studied by docking the most active compound 6c and Acarbose within the protein target (PDB ID: 3L4U). Compounds 2, 6c, and Acarbose show a docking score of -5.048, -6.14, and -12.118, respectively. Further, molecular dynamics simulations for 100 ns are performed to gain a detailed understanding of the complex stability. Binding energy for both the simulated complexes is calculated using MMGBSA and MMPBSA analysis, where, compound 6c exhibits a ΔGbind of -15.74 kcal mol-1.
