Given their unique properties, electrospun-medicated nanofibers can be used as oral fast-dissolving DDSs of poorly water-soluble drugs. However, significant issues, such as scalable productions and solid dosage form conversions, need to be investigated.

As the confirmed number of cases has reached 83 million worldwide, the potential severity and the deadly complications of the disease requires urgent development of effective drugs for prevention and treatment. No proven effective treatment for this virus currently exists. Most of the antiviral discovery efforts are focused on the repurposing of approved or clinical stage drugs. This review highlights the small-molecule repurposed antiviral agents that are currently under investigation in clinical trials for COVID-19. M344 These include viral polymerase and protease inhibitors remdesivir, galidesivir, favipiravir, ribavirin, sofosbuvir, tenofovir/emtricitabine, baloxavir marboxil, EIDD-2801, lopinavir/ritonavir; virus-/host-directed viral entry and fusion inhibitors arbidol chloroquine/hydroxychloroquine, chlorpromazine, camostat mesylate, nafamostat mesylate, bromhexine and agents with diverse/unclear mechanism of actions as oseltamivir, triazavirin, ivermectin, nitazoxanide, niclosamide and BLD-2660. The published preclinical and clinical data to date on these drugs as well as the mechanisms of action are reviewed.Over the past several years, remarkable progress towards the recognition of new therapeutic targets in tumor cells has led to the discovery and development of newer scaffolds of anti-tumor drugs. The exploration and exploitation of epigenetic regulation in tumor cells are of immense importance to both the pharmaceutical and academic biomedical literatures. Epigenetic mechanisms are indispensable for the normal development and maintenance of tissue-specific gene expression. Disruption of epigenetic processes to eradicate tumor cells is among the most promising intervention for cancer control. Polycomb repressive complex 2 (PRC2), a complex that methylates lysine 27 of histone H3 to promote transcriptional silencing, is involved in orchestrating significant pathways in a cell. Overexpression of PRC2 has been found in a number of cancerous malignancies, making it a major target for anti-cancer therapy. Despite its well-understood molecular mechanism, hyperactivation and drug resistance mutations in its subunits have become a matter of discussion. This review outlines the current understanding of the components of PRC2 in active complex formation and assesses their potential as a promising therapeutic target for cancer therapy. We also review the effects of mutations in the PRC2 components, in the purview of human cancers. Finally, we discuss some of the current challenges for therapeutic drug designs targeting the PRC2 complex.Post Translational Modification (PTM) is a process in which covalent addition of functional groups on protein occurs to maintain their structure, function and stability. Every PTM process in our living system occurs to enhance the functional diversity of a protein. But sometimes, it occurs without any regulation and that might lead to autoimmunity. Rheumatoid arthritis (RA) is one such chronic, inflammatory, autoimmune disease that affects the joints. Proper treatment can make the symptoms manageable for RA, but it is not curable. Delayed diagnosis of RA can cause severe bone pain, stiffness, inflammation, redness in joints and affect other parts of the body such as the liver, kidney, etc. Early diagnosis of RA is necessary to manage the aggressive symptoms. Currently, Rheumatoid factor (RF) and anti-citrullinated cyclic peptide (Anti-CCP) are considered as biomarkers to diagnose RA. Besides citrullination, several other PTMs are also involved in the generation of autoantibodies, such as carbamylation, glycosylation, glycation, acetylation, ubiquitination, proteolysis, phosphorylation, and lipidation. The aim of this review is to elucidate several changes in the form, nature, and function of PTMs in RA. This review will give a recent overview on the role of PTMs in the pathogenesis of RA with a focus on the post-translational modifications.Enzymes are the biocatalysts synthesized by living organisms having high specificity, catalytic activity, and a broad range of applicability. One such biotechnologically relevant enzyme is keratinase with various industrial applications that capture a significant place in the enzyme market. It belongs to the proteolytic enzyme group that cleaves the highly stable and fibrous protein, keratin through hydrolysis. Keratins are hard-degrading fibrous proteins insoluble in natural solvents and water. It is frequently aggregated in nature and expressively present in the plumes, hair, nail, horn, skins, feet, etc. The broad range of microorganisms, such as bacteria, fungi, and actinomycetes, have been accounted for producing keratinases with significant biotechnological applications. Successful application of this group of enzymes has been seen in various industries such as farming, laundry detergent, cosmetics, animal feed, pharmaceutical, leather, and textile. Moreover, they have found remarkable usability in environment friendly waste management also. This paper focuses on the structure, sources, and various applications of this industrially important enzyme.
Due to side-effects and low efficacy of common drugs on new resistant strains of Mycobacterium tuberculosis (Mtb), investigation on novel drugs and natural compounds from rich sources of endemic plants is required. Thus, in the present study, the anti-mycobacterial effects of 22 Iranian endemic or rare plant extracts on multi-drug resistance (MDR) and extensively-drug resistance (XDR) Mtb isolates were evaluated.

Twenty-two Iranian endemic and rare plant species from 9 families were collected and extracted by methanol. Their inhibitory-effects were then evaluated against Mtb H37Rv strain, seven clinical MDR-TB, and two XDR-TB isolates using the resazurin microtiter assay (REMA) method. The best of them were then fractionalized by five different polar solvents (Petroleum- Ether, Dichloromethane, Ethyl-Acetate, n-butanol, and water). To find anti-mycobacterial fractions, the inhibitory effect of isolated fractions was tested on Mtb H37Rv.

Out of the 22 plants, 14 plant extracts demonstrated anti-mycobacterial activity with minimum inhibitory concentration (MIC) ranging from 4 to 30μg/mL against Mtb H37Rv.
