چکیده

COVID-19 é uma doença altamente contagiosa causada pelo coronavírus da síndrome respiratória aguda grave 2 (SARS-CoV-2) tornando-se grande ameaça em todo o mundo devido à sua rápida natureza de disseminação e variantes mais agressivas, como caso Ômicron. A principal estrutura interação do vírus com a célula hospedeira região pico proteína Spike chamada RBD, que teve diversas mutações, dificultando busca fármacos. Com base nesse cenário, presente trabalho objetivo avaliar perfil interações entre moléculas origem naturais frente RBD (S) SARS-CoV-2, variante Na primeira etapa metodológica ocorreu modelagem molecular sequência obtida no Brasil testes para caracterização validação estrutural. Em seguida, foi realizado docking 6 ligantes fitoquímicos: Curcumina, Carvacrol (±)-Limoneno, Glicirrizina, Alicina Quercetina-3-Arabinoside na específica modelada, após obter os melhores resultados, complexos formados foram avaliados por RMSD RMSF. homologia obteve-se baixos erros estruturais. Nas cada fitoquímico, as glicirrizina quercetina apresentaram maior afinidade molecular, ligando-se ao sítio ativo encontrado RBD. dinâmica confirmou dos estabilidade durante simulações. um potencial molécula S, partir genoma ômicron inédita SARS-CoV-2 sequenciada Brasil.

Analysis of Sars-CoV-2 RBD Mutations in Khuzestan Province, Iran—A Retrospective Study, 2021

Background and Objective: One of the main reasons for the ongoing pandemic is the substitutions in the Receptor binding domain(RBD), which is involved in binding to the ACE2 receptor. Methods: Oro-nasopharyngeal swabs were collected from 41 confirmed patients between September 2020 and May 2021 to analyze the mutations of SARS-CoV-2 RBD in Khuzestan Province. Bi-Directional sequencing was use...

Reduced incorporation of SARS-CoV spike protein into viral particles due to amino acid substitutions within the receptor binding domain.

Cell clone #21 is a long-term producer of the infectious SARS-coronavirus, although the incorporation rate of spike (S) protein into virions is significantly lower. Sequencing analysis of the viral structural proteins revealed four and one amino acid substitutions in the S and membrane (M) proteins, respectively. We demonstrated, using a viral-like particle formation system, that the S mutation...

Cryo-EM structures of MERS-CoV and SARS-CoV spike glycoproteins reveal the dynamic receptor binding domains

The envelope spike (S) proteins of MERS-CoV and SARS-CoV determine the virus host tropism and entry into host cells, and constitute a promising target for the development of prophylactics and therapeutics. Here, we present high-resolution structures of the trimeric MERS-CoV and SARS-CoV S proteins in its pre-fusion conformation by single particle cryo-electron microscopy. The overall structures...

In silico design a multivalent epitope vaccine against SARS-CoV-2 for Iranian populations

Background: Due to high genetic variation in human leukocyte antigen )HLA( alleles, epitope-based vaccines don’t show equal efficacy in different human populations. therefore, we proposed a multi-epitope vaccine against SARS-CoV-2 for Iranian populations. Materials and Methods: For this purpose, the proteins without allergenicity and high antigenicity as well as conservancy level from SARS-CoV...
