Identification of natural anti-TMPRSS2 potential products through homology modeling, virtual screening and molecular dynamics simulation studies

The latest outbreak of the severe acute respiratory syndrome Coronavirus-2 (SARS-COV-2) has led to Covid-19 pandemic. The absence of therapeutic drugs and vaccines causes severe loss and economic losses throughout the world. SARS-COV and SARS-COV-2 employ host Serentease TMPRSSS2 for priming spike protein for viruses into the host cell. The potential way to reduce the initial site SARS-COV-2 infection is possible to inhibit TMPRSS2 activities. In this study, the three-dimensional structure of TMPRSSS2 was produced by homology modeling and then validated with a number of parameters.

Virtual screening based structure from the Selleckchem database is carried out through ‘virtual work flow’ (VSW) to determine the potential for tmprss2 inhibitors such as tin. Camostat and Bromhexine are known as TMPRSS2 inhibiting drugs, therefore this is used as a control molecule throughout the study. Based on better dock scores, binding free energy and binding interactions compared to control molecules, six molecules (neohesperidin, myricitrin, quercitrine, naringin, iCariin, and ambroxol) are found promising to TMPRSSS2.

Analysis of binding interactions reveals a number of significant binding interactions with the binding place of amino residue TMPRSS2. The simulation study of the All-Atom Molecular Dynamics (MD) indicates that all molecules proposed maintain in receptors in dynamic countries. Binding energy is calculated from the MD simulation trajectory also supports the strong affinity of molecules against TMPRSS2. The proposed molecules belong to the bioflavonoid phytochemical class and reported to have antivirus activity, our research shows possible potential applications in Covid-19.

Molecular characterization of Campylobacter spp. Restored from beef products, chicken, sheep and pork in retail in Australia

The Australian Campylobacteriosis level is one of the highest in developed countries, but only a limited job that has been done to characterize the Campylobacter spp. in Australian retail products. We did the whole seuensing genome (WGS) on 331 C. coli and 285 C. Jejuni from retail chicken meat, as well as beef, chicken, sheep and jeracles (organs). Campylobacter isolates are very diverse, with 113 types of order (STS) including 38 STS novels, which were identified from 616 isolates. Genome analysis shows a very low level (2.3-15.3%) resistance to aminoglycosides, beta-lactam, fluoroquinolone, macrolide and tetracycline antibiotics.

The majority (> 90%) of isolates (52/56) have a T86i mutation related to fluoroquinolone in the GYRA gene owned by ST860, ST2083 or ST7323. Devote 44 pig isolates very diverse, representing 33 STS (11 novels STS) and buried genes related to resistance to aminoglycosides, lincosamides and makrolides which are generally not found in isolates from other sources. The prevalence of very low multidrug resistant genotypes (<5%), but ten times higher in C. coli than C. Jejuni. This research highlights the Campylobacter spp. From retail products in Australia are very diverse genotypes and important differences in existing antimicrobial resistance between campylobacter species and animal sources.

Molecular identification and evaluation of wild yeast performance from various Ethiopian fermentation products

Various types of yeast and lactic acid bacteria dominate in spontaneous fermented products (food, beverage, and spices) which are usually consumed in Ethiopia. The purpose of this study is to identify efficient fermentation yeast from fermented food, fermented drinks, honey and molasses using the genotype method. Of the 70 samples tested, 180 different wild yeast isolates were restored.

A total of 23 isolates are chosen for genome analysis based on the basis of biomass results, fermentation capacity, and yeast performance. Analysis of nucleotide sequences of the internal transcript spacer-5.8s RDNA region revealed that the original yeast isolates have a close link with Saccharomyces cerevisiae, Candida Humilis, Kazachstania Botderi, Pichia Fermentans and Pichia Kudriavzevii with nucleotide similarities greater than 97%. This study shows a diversity of high indigenous wild yeats in strong fermented products and strains have higher biomass results, good gas production and extraordinary yeast capacity that shows the potential attached to the roasting industry.

Molecular targets of natural products for chondroprotection in damaging joint diseases

Osteoarthritis (OA) is the most common type of arthritis that occurs in age population. This affects all joints in the body and decreases articular cartilage and subchondral bones. Although OA pathophysiology becomes different, vulnerable resorption is still a symbol of osteoarthritis. Matrix Metalloproteinases (MMPS) is an important proteolytic enzyme that decreases cellular matrix protein (ECM) in the body. MMP contributes to the turnover of cartilage and damage; Their level has increased in the Joint network of OA patients. The application of condropotective drugs neutralizes MMP activities.

Natural products originating from herbs and plants developed as traditional drugs have been considered, due to their potential biological effects. The therapeutic value of natural products in OA has increased in a reputation due to their clinical impact and unsignificant side effects. Some MMP inhibitors have been used as therapeutic drugs, for a long time. Recently, various types of compounds were reviewed for their biological activities. In this review, we summarize many natural products for the development of MMP inhibitors in rheumatic diseases and describe the main signal targets involved for the treatment of damaging joint diseases.
