Reportedly, a series of dietary lipids are identified as 1-cis-4-cis-pentadiene polyunsaturated fatty acids (PUFAs), which play a dominant role in prostate carcinogenesis. Four species of human lipoxygenases (LOXs), a family of nonheme iron-containing enzymes, mediate the deoxygenation of the aforementioned PUFAs. 15-LOX-1 in particular metabolizes the [Formula: see text]-6 lipids and generates certain metabolites (e.g., 13-(S)-hydroxyoctadecaenoic acid) which results in vascular homeostasis, cell proliferation and tissue differentiation in the prostate. Furthermore, in prostate cancer (PCa), the expression of 15-LOX-1 is elevated and positively correlated with the Gleason score of the tumor (an indicator of the disease severity). As membrane receptors, kinases and transcriptional factors are all affected by carcinogenic signals of 15-LOX-1, therapeutic agents that directly inhibit this enzyme can be advantageous in the treatment of PCa. To our knowledge, there are limited effective treatments for PCa, and there is no therapy for its metastatic condition. In this respect, 15-LOX-1, as an appropriate candidate for drug development, was subjected to homology modeling, phylogenic assessment, cross-docking analysis and molecular dynamics (MD) simulation to identify an eligible inhibiting agent amongst a library of 30 potential targeting compounds for PCa management.","PeriodicalId":15603,"journal":{"name":"Journal of Computational Biophysics and Chemistry","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46288457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to these high coefficients, the heat and mass transfer rates will be high in the appliances equipped with the jet flow. Further, the existence of the magnetic field helps in controlling the velocity and the presence of the gyrotactic microorganisms ensure proper mixing of nanoparticles. A dilute nanoparticle suspension is assumed so that it will not affect the movement of motile cells that leads to bioconvection. Hence, this paper aims to analyze the characteristics of heat transfer as well as mass transfer of the jet flow of Williamson nanofluid past a porous stretching sheet in the existence of microorganisms. The mathematical model obtained as a result of these assumptions is transformed into nonlinear ordinary differential equations for which acceptable solutions are obtained using the numerical method. The results thus obtained are presented graphically and based on the outcomes, it is perceived that the magnetic field has control over the velocity profile thus influencing the thermal profile. The increase in the Williamson parameter also reduces the velocity of the fluid flow. Further, an increase was noticed in the thermal and concentration profiles of the nanofluid for higher values of thermophoresis parameter and the increase in the porosity reduced the speed of the flow of nanofluid.","PeriodicalId":15603,"journal":{"name":"Journal of Computational Biophysics and Chemistry","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49394508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Docking studies have revealed that inhibitor binding affinity can be influenced by several key binding interactions with Phe114 and Lys116 from chain B and Val21, Phe25, His28 and Lys29 from chain C in the FLAP-binding site. A ligand-based alignment three-dimensional (3D)-quantitative structure–activity relationship (QSAR) was adopted, resulting in a robust model with a statistically significant noncross-validated coefficient ([Formula: see text]), a cross-validated correlation coefficient ([Formula: see text]) and a predictive squared correlation coefficient ([Formula: see text]). Overall, the analysis revealed the important electrostatic and steric attributes responsible for the FLAP inhibitory activity, which appeared to correlate well with the docking results. In addition, two statistically significant two-dimensional (2D)-QSAR models ([Formula: see text], [Formula: see text] and [Formula: see text], [Formula: see text]) were developed by a genetic function approximation (GFA). HypoGen 1, a proposed pharmacophore model, was used for database mining to identify potential new FLAP inhibitors. The bioactivity of the retrieved hits was then evaluated in silico based on the validated QSAR models, followed by pharmacokinetics and toxicity predictions.","PeriodicalId":15603,"journal":{"name":"Journal of Computational Biophysics and Chemistry","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47990079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
