Abstract The nucleocapsid (N) protein of SARS-CoV-2 is known to participate in various host cellular processes, including interferon inhibition, RNA interference, apoptosis, and regulation virus life cycles. Additionally, it has potential as a diagnostic antigen and/or immunogen. Our research focuses on examining structural changes caused by mutations the N protein. We have modeled complete tertiary structure native mutated forms using Alphafold2. Notably, contains 3 disordered regions....
To investigate the molecular cause of persistent fevers in a patient returning from working overseas, whom investigations for tropical diseases yielded negative results.DNA was extracted patient's whole blood, leukocyte subpopulations, saliva, hair root, and sperm. The TNFRSF1A gene analyzed by polymerase chain reaction (PCR), allele-specific PCR, Sanger sequencing, next-generation sequencing. In silico modeling performed to predict structural functional consequences tumor necrosis factor...
Familial Mediterranean fever (FMF) is a genetically determined disease transmitted through autosomal recessive inheritance. Recently, rare but similar to FMF, pyrin-associated autoinflammation with neutrophilic dermatosis (PAAND), has been discovered. PAAND inherited dominantly and characterized by recurrent fevers. The cause of the point mutations in MEFV gene. pyrin protein product this gene one main factors disease's progression. This paper examines interaction between 14-3-3 screens for...
Piperazine, norbornene, and their derivatives are valuable scaffolds in rational drug design, with promising therapeutic applications various diseases, including cancer. Given that hybridization of privileged structures is a highly effective strategy development, we synthesized piperazine containing norbornenyl fragment using straightforward synthetic pathway. Eight norbornenylpiperazine compounds (4a–4h) were evaluated for potential interactions target proteins, along an silico assessment...
African swine fever virus (ASFV) is the causal agent of a fatal disease domestic for which no effective antiviral drugs are available. Recently, it has been shown that microtubule-targeting agents hamper infection cycle different viruses. In this study, we conducted in silico screening against colchicine binding site (CBS) tubulin and found three new compounds with anti-ASFV activity. The most promising compound (6b) reduced ASFV replication dose-dependent manner (IC50 = 19.5 μM) cellular...
Starting from 1972, colchicine is known as the most useful drug for prevention of familial Mediterranean fever attacks. However, some patients do not respond to treatment, even taken in high doses. Despite fact, that different hypotheses have been proposed, molecular mechanisms resistance are completely clear. It generally known, binds β-tubulin and inhibits microtubules polymerization. The gene has SNPs, which lead amino acid substitutions, them located binding site (CBS). We assumed, this...
Pyrin protein is the product of MEFV gene, mutations in which cause manifestation familial Mediterranean fever (FMF). Functions pyrin are not completely clear. The secondary structure represented with four domains and two motifs. Mutations p.M680I, p.M694V, p.M694I, p.K695R, p.V726A, p.A744S, located B30.2 domain protein, responsible for most common severe forms FMF. All motifs pyrin, directly or indirectly, involved protein-protein interaction proteins apoptosis regulate cascade...
Abstract Human carbonic anhydrase XII (hCA XII) isozyme is of high therapeutic value as a pharmacological target and biomarker for different types cancer. The hCA one the crucial effectors that regulates extracellular intracellular pH affects cancer cell proliferation, invasion, growth metastasis. Despite fact interaction features hCAs inhibitors with catalytic site enzyme are well described, lack in selectivity traditional based on sulfonamide group or related motifs an urgent issue....
Influenza virus remains a major public health challenge due to its high morbidity and mortality seasonal surge. Although antiviral drugs against the influenza are widely used as first-line defense, undergoes rapid genetic changes, resulting in emergence of drug-resistant strains. Thus, new that can outwit resistant strains significant importance. Herein, we deep reinforcement learning (RL) algorithm design chemical entities (NCEs) able bind native H275Y mutant (oseltamivir-resistant)...
Abstract Human carbonic anhydrase XII (hCA XII) has gained therapeutic value in the field of medicinal chemistry as a pharmacological target and biomarker for different types cancer. Despite fact that interaction features hCAs inhibitors with catalytic site enzyme are well described, lack selectivity traditional hCA is an urgent issue. This study was devoted to identification novel potential using comprehensive set computational approaches, including generation structure-and ligand-based...
Pyrin protein is the product of MEFV gene, mutations in which cause manifestation Familial Mediterranean Fever (FMF). Complete tertiary structure pyrin and effects on it are still experimentally not studied. Mutations - E148Q, M680I, M694V, M694I, V726A, A744S R761H induce most widespread severe forms FMF. One striking feature FMF phenomenon complex allele mutations. In case mutations, will contain more than one mutated amino acids. From currently known there those that combine single...
The M680I and M694V mutations located in the B30.2 pyrin domain are responsible for manifestation of most common forms Familial Mediterranean fever. It is well known that a malfunction pyrin-caspase-1 complex main cause inflammation FMF. purpose this study was to identify possible changes tertiary structure mutated determine their potential consequences formation complex. Using computer modeling, it found above change domain, causing shifts binding sites altering energy interaction between caspase-1.
Mutations M680I, M694V and V726A of Pyrin - the product MEFV gene are localized at domain B30.2 (PB30.2D) responsible for manifestation most widespread severe forms FMF. From other hand, it is well known that malfunction pyrin-caspase-1complex main reason inflammation during Therefore, we suggest comparative investigation normal mutated pyrin caspase-1 interaction will help to reveal possible link between those mutations structural changes influence formation pyrin-caspase-1 complex.
Cytostatic colchicine is widely used in the treatment of Familial Mediterranean fever, but it has several side effects. For finding new, more effective drugs with higher affinity and diminishside effects we carried out virtual screening potential inhibitors main target colchicine, polymerization tubulin by evaluating 25745 compounds, structurally related to colchicine. We have identified 11 commercially available compounds tubulin. Compounds highest binding scores include trimethoxybenzene...
