Moreover, it has become clear that coronaviruses mutate quite often, which reduces the effectiveness of available vaccines and forces the regular creation of new ones. The main viral protease M<sup>pro</sup> is a suitable target for direct-acting drugs. Currently, there is only one recommended anticoronavirus drug, nirmatrelvir, which, however, does not have all the properties necessary for widespread and effective use. Thus, the development of a highly selective and effective protease inhibitor that can be taken orally still remains relevant. In this work, we performed an in-depth literature review of M<sup>pro</sup> inhibitor studies and conducted extensive molecular dynamics simulations of M<sup>pro</sup>-inhibitor complexes with computational prediction of binding ability and ADME (absorption, distribution, metabolism and excretion) properties of new compounds. On the basis of the literature review we composed a set of criteria that a potent inhibitor must meet. Then we created a set of possible inhibitors and their parts, which presumably allows all the necessary properties, namely, high affinity for the viral enzyme, selectivity, bioavailability and solubility, to be achieved. </p></div>","PeriodicalId":621,"journal":{"name":"Journal of Computer-Aided Molecular Design","volume":"39 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145057638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the anti-diabetic potential of <i>Cotula cinerea</i> essential oil (EO) through in vivo, in vitro, and computational methodologies. In vitro enzyme inhibition assays demonstrated that <i>C. cinerea</i> EO effectively inhibits α-amylase and α-glucosidase, indicating its potential role in glucose regulation. In vivo studies further confirmed its hypoglycemic effects. GC–MS analysis identified 31 bioactive compounds within the EO. Molecular docking studies revealed that six of these compounds exhibited strong binding affinities to α-amylase and α-glucosidase, comparable to those of the standard drug acarbose (ARE). Among them, cis-verbenyl acetate (CVA) and β-terpineol (βTP) showed the highest docking scores against both enzymes. ADMET analysis confirmed their favorable pharmacokinetic properties, drug-likeness, and low toxicity risks. Molecular dynamics simulations demonstrated the stable binding of CVA and βTP with both enzymes, exhibiting lower RMSD and RMSF values compared to ARE, along with favorable Rg and SASA parameters. MM-PBSA calculations further validated their strong binding affinities. Density Functional Theory calculations provided deeper insights into the electronic characteristics of CVA and βTP, revealing their frontier molecular orbitals distributions and energy gap (∆E) values. The molecular electrostatic potential analysis identified key electron-rich and electron-deficient regions, suggesting potential interaction sites with the target enzymes. The observed reduction in ∆E values under aqueous conditions indicated increased molecular stability and reactivity within physiological environments, further supporting their role in enzyme inhibition. Overall, this study highlights <i>C. cinerea</i> EO as a promising natural source for diabetes management.

This research proposes a protein generation method based on the generalized diffusion model, which breaks through the traditional diffusion model’s reliance on Gaussian noise, enables more flexible protein sequence generation, and preliminarily verifies its advantages. Specifically, protein sequences were first encoded using one-hot encoding and input into the diffusion model to generate novel sequences. Subsequently, the tertiary structures of the generated proteins were predicted using AlphaFold, followed by structural alignment and backbone distance calculation via PyMOL to select the optimal sequences. The predicted derivative protein sequence A_005 was screened from the generated sequences and subjected to an affinity assay with Protein A parental. Experimental results revealed that A_005 exhibited remarkably high affinity, as well as a satisfactory dissociation rate and association rate. The findings demonstrate that the protein generation method based on the generalized diffusion model can effectively design protein sequences with high structural and functional similarity to target sequences. While prior studies have shown that both DDPM and generalized diffusion models achieve high generation quality, the generalized diffusion model outperforms in terms of task adaptability. Our research not only opens new technological pathways for protein design but also lays a solid foundation for future applications in biomedicine, providing significant theoretical and experimental evidence for subsequent drug development.</p></div>","PeriodicalId":621,"journal":{"name":"Journal of Computer-Aided Molecular Design","volume":"39 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144934499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In parallel, in silico ADMET descriptors were extracted via ADMETlab 3.0, providing quantitative insight into lipophilicity, permeability, distribution volume, and metabolic clearance. All features were normalized and integrated into a joint dataset for principal component analysis and hierarchical clustering.

Conventional approaches such as surgery, radiotherapy, and chemotherapy often fail to achieve satisfactory outcomes, underscoring the urgent need for more effective targeted therapies. In this study, we have developed novel AKT inhibitors—compounds 3260-0411, V012-5231, and V016-4965. These compounds demonstrate a substantial reduction in both AKT protein and mRNA levels in U251 and T98G glioma cells. Furthermore, our in vitro experiments reveal that these inhibitors effectively suppress AKT1 enzyme activity and induce apoptosis in glioma cells. Molecular dynamics simulations indicate that all three compounds exhibit excellent dynamic stability when bound to AKT; notably V016-4965 demonstrates the highest binding stability among them. Collectively, our findings suggest that compounds 3260-0411, V012-5231, and V016-4965 hold great promise as targeted therapies against AKT for treating glioma—a challenging malignancy with limited management options.</p></div>","PeriodicalId":621,"journal":{"name":"Journal of Computer-Aided Molecular Design","volume":"39 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144868772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
