Tuberculosis (TB) is caused by a bacterium called Mycobacterium tuberculosis, identified as a global health emergency by the world health organization. The development of drug-resistance stains due to spontaneous gene mutation has been a major boost to research in the pathogenicity and biochemistry of Mtb. To combat drug resistance to tuberculosis, new drugs and methodologies are emerging. Since, starting itself mycobacterium complex cell wall has been a choice for widely selected targets for anti-TB drugs. Peptidoglycan, arabinogalactan, and mycolic acid are the basic layers supporting cell growth. The current work investigates virtual screening for optimal small molecule inhibitors targeted against selected mycolic acid targets (β-keto acyl ACP synthase, enoyl acyl ACP-reductase and Polyketide synthase 13). A small library of 485 compounds was designed and docked into a selected target core to identify the potential inhibitor. The designed compounds were subjected to docking studies using Glide (Schrodinger). InhA was the most suitable mycolic acid inhibitor target for the designed compounds. Further, the effectiveness of the study was evaluated by comparing the...

Pan-genome analysis can identify the core genome, which is the total number of genes present in all strains of a bacterial species. Further essential genes can be identified in this core set of genes which gives us a minimal number of genes required for the survival of the bacteria. This set of genes can be analyzed to develop new antimicrobial agents against pathogenic, multidrug-resistant bacteria such as Listeria monocytogenes which causes several primary and secondary infections in humans. Pan-genome analysis of 38 strains of Listeria monocytogenes was performed to estimate 2331 genes in core genome, 1056 genes in the dispensable genome, and 152 genes in the strain-specific genome. Essentiality analysis of 2331 core genome proteins predicted 965 essential core-genome families (ECGFs). Furthermore, the identification of host non-homologous proteins using BLASTP with the Homo sapiens proteome resulted in 485 non-homologous essential core-genome families (NH-ECGFs). These putative proteins can be analyzed to identify novel drug targets that could generate broad-spectrum, safe and effective therapeutic agents against Listeria monocytogenes infections in...

Medicinal plants belong to the Labiatae family, commonly known as the mint family. This family comprises the Anisomeles malabarica, which contain biologically important phytochemicals. Focus on solvent extraction of selected medicinal plant parts and its phytochemical analysis gives an insight for herbal drug discovery. A heat continuous percolation experiment was conducted for 24 hours using three different solvents, namely ethanol, methanol, and chloroform using the Soxhlet apparatus. The phytochemical examination of Anisomeles malabarica leaf extracts by the three solvents revealed that the extracts are abundant in alkaloids, saponins, tannins, flavonoids, and glycosides, all of which have been linked to the pharmacological effects of the plant. In the current study, derivatization procedures were employed to analyze both polar and non-polar compound present in the solvent extracts. Based on the GC-MS analysis, large amounts of carboxylic acids, which contain both saturated and unsaturated fatty acids, hydrocarbons, including alkanes and alkenes are responsible for the oily quality of all three extracts. According to analysis, the majority of polar molecules, such as alcohols,...

The development of Nanotechnology has paved the way to study various nanomaterials. Nanoparticles are structures that measure the size from 1-100nm. Widely used nanoparticles are usually prepared using noble metals, that is, gold, silver, palladium, and platinum. At the same time, they find their way into a wide range of applications in medicine, electronics, energy saving, environment, textile, cosmetics, biomedical, etc. The natural reducing agents in plants, such as carbohydrates, flavonoids, etc., reduce the silver, generating potential silver nanoparticles. Silver nanoparticles are intended to be used for the present study generated through green synthesis using millets. Millets are small-seeded grasses that are hardy and grow well in dry zones as rain-fed crops under marginal conditions of soil fertility and moisture. The different varieties of millets intended to be used in the project are Barnyard millet, Finger millet, Foxtail millet, Kodo millet, little millet, Pearl millet, Prosomillet, Sorghum. The Silver nanoparticles synthesized through an aqueous extract of different varieties were checked for their quality using UV-VIS spectrophotometer and Scanning electron...

An example of the human microbiota is Staphylococcus saprophyticus, a gram-positive, non-hemolytic pathogenic bacterium. It’s a prevalent culprit behind simple infections associated with the urinary tract, especially among sexually active young women. It has a high colonization rate in the perineum, rectum, urethra, cervix, and gastrointestinal system and is also quite lethal. Because of their ability to form a biofilm, these bacteria are highly resistant to antibiotics. Thus, unconventional methods, such as the use of silver nanoparticles, have been devised to counteract this type of biofilm. The silver nanoparticles are produced in an environmentally friendly way by utilizing an extract of water from banana peels. UV/Vis, FTIR, SEM, and EDAX are the four methods used to characterize the NPs and validate their production. Using the Screening method and SEM analysis, we show that silver nanoparticles inhibit the growth of Staphylococcus saprophyticus ATCC 15305, the most prevalent bacteria responsible for urinary tract infections....
