Shenqi Jiangtang Granule (SJG), a classical prescription of traditional Chinese medicine, is widely used to treat diabetes and its complications. Although, the clinical efficacy of SJG, is sufficient, the pharmacokinetic behavior of various substances in the plasma of SJG is unknown.

The aim of this study was to investigate the plasma pharmacokinetics during absorption of SJG after oral administration in rats.

A rapid and accurate ultra-high performance liquid chromatography/tandem mass spectrometry (UPLC- MS/MS) method was developed for the simultaneous determination of eight analytes in SJG, including gomisin D, schisandrin A, schisandrin B, schizandrol A, schizandrol B, ginsenoside Rd, ginsenoside Re and notoginsenoside Ft1. The analysis was carried out on a BEH C18 column (2.1 mm × 50 mm, 1.7 μm) with gradient elution at a flow rate of 0.2 mL/min in a mobile phase consisting of 0.1% formic acid water and acetonitrile. In addition, lignans and saponins were detected in positive ion mode and negative absorbed. This approach could be applied to study the pharmacokinetic characteristics of various analytes in plasma after oral administration of SJG in rats.
The underlying cause of major neurodegenerative disorders remains a health-care mystery. read more The thoroughly investigated causes include oxidative stress, inflammation, environmental factor, mitochondrial dysfunction, and irregular neuronal protein aggregation. Withania somnifera has been used for more than 2500 years as a useful medicinal plant to improve disease defense, prevent aging, rejuvenate the body in a vulnerable situation, and generate a feeling of mental well-being. However, a persuasive paper emphasizing its neuroprotective nature is missing.

In the current review, we have delineated the protective role of W. somnifera against various neurological disorders and its progress in delivery systems.

The database used in the retrieval of data were PubMed, Scopus, Science direct, and SciFinder. The keywords used were W. somnifera, Ashwagandha, neuroprotective activities, etc. The principal source of the data retrieval includes research articles, review papers, and short communications from reputed publsia, stroke, and anxiety. Furthermore, natural compounds in nano sizes range possess the better neuroprotective activity. Consequently, polymeric nanomicelles, nanoparticles, and nanofibers of natural products are used in the treatment of neurodegenerative diseases Conclusion The current review substantially deciphered the protective role of W. somnifera against various neurological disorders. However, future studies are further required better to understand the molecular mechanisms behind their neuroprotective nature.
This paper is prepared to reveal about an urgent industrial scheme for a fast and facile total synthesis of umifenovir (arbidol) (by one-pot stages) as an antiviral agent for treating 2019-nCoV virus via inhibiting its viral replication in the human cells. As COVID-19, takes thousands of lives all around the world, it seems that the medicinal resources would not be enough to supply billions of peoples, currently living on the planet earth. Thus, this pandemic and its subsequent impacts on the natural order of our life, would be one of the most important threats against the entire human race. Aims & Objective Due to this, in this project, we have made attempts to find an operative approach for synthesizing this compound as an active pharmaceutical ingredient (API), which showed it could be effective in inhibiting the newly emerged coronavirus.

The designed scheme uses relatively cheap precursors, and contains one pot stages, instead of seven time consuming, and more costly, linear steps. Also, it is trntiometric titration), and related purity analysis (by High performance liquid chromatography-Ultraviolet Detector (HPLC-UV)) (about 99.8%) were performed and described to give a more clear industrial scheme.
Deubiquitinating enzymes (DUBs) protein family have been implicated in some deregulated pathways involved in carcinogenesis such as cell cycle, gene expression, and DNA damage response (DDR). Zinc finger with UFM1-specific peptidase domain protein (ZUFSP) is one of the recently discovered members of the DUBs Objectives To identify and cross validate the ZUFSP binding site using the bioinformatic tools including SiteMap & Metapocket respectively. link2 To understand the molecular basis of complementary ZUFSP-Ub interaction and associated structural events using MD Simulation Methods In this study, four binding pockets were predicted, characterized, and cross-validated based on physiochemical features such as site score, druggability score, site volume, and site size. Also, Molecular dynamics simulation technique was employed to determine the impact of ubiquitin-binding on ZUFSP Results Site 1 with a site score 1.065, Size 102, D scores 1.00, and size volume 261 was predicted to be the most druggable site. Structural studies revealed that upon ubiquitin-binding, the motional movement of ZUFSP was reduced when compared to the unbound ZUFSP. Also, the ZUFSP helical arm (ZHA) domain orient in such a way that it moves closer to the Ub, this orientation enables the formation of a UBD which is very peculiar to ZUFSP.

The impact of ubiquitin on ZUFSP movement and the characterization of its predicted druggable site can be targeted in the development of therapeutics.

Cell heterogeneity exists among different tissues even in the same type of cells. Cell heterogeneity leads to a difference in cell size, functions, biological activity, and for cancer cells it causes different drug responses and resistance. Meanwhile, microfluidics is a promising tool for single-cell research to reveal cell heterogeneity.

Through literature research conducted over the past ten years on microfluidics, we summarize and introduce the application of microfluidics in single-cell separation and manipulation, featuring techniques such as acoustic manipulation, optical manipulation, single-cell trapping, and patterning, as well as single-cell omics including single-cell genomics, single-cell transcriptomics, single-cell proteome, single-cell metabolome, and drug development.

Microfluidics is a flexible, precise tool, and it is easy to integrate with different functions. Firstly, it can be used as an important tool to separate rare but important cells according to the cell`s biological or physical properties. Secondly, microfluidics can provide the possibility of single-cell omics. Thirdly, microfluidics can be used in drug development specifically in drug delivery and drug combination. link3 Meanwhile, droplet microfluidics has gradually become the most powerful tool to encapsulate single-cells with other reagents for DNA, RNA, or protein analysis.

Microfluidics is a robust platform technology which is able to accomplish rare cell separation, efficient single-cell omics analysis and provide a platform for drug development and drug delivery.

It is characterized by a delay in cognitive capabilities, repetitive and restricted behaviors and deficit in communication and social interaction. Several factors seem to be associated with ASD development; its heterogeneous nature makes the diagnosis difficult and slow since it is essentially based on screening tools focused on stereotypical and repetitive behaviors, gait, facial emotion expression and speech assessments. Recently, artificial intelligence (AI) has been widely used to investigate ASD with the overall goal of simplifying and speeding up the diagnostic process as well as making earlier access to therapies possible. The aim of this review is to provide an overview of the state-of-the-art research in the ASD field identifying and describing machine learning (ML) approaches in ASD literature that could be used by clinicians to improve diagnostic capability and treatment efficiency. A systematic search was conducted and the resulting articles were subdivided into several categories reflecting the different fields of study associated with ASD research. The existing literature has widely demonstrated the potential of ML in several types of ASD study analyses behavior, gait, speech, facial emotion expression, neuroimaging, genetics, and metabolomics. Therefore, AI techniques are becoming increasingly implemented and accepted, so highlighting the power of ML approaches to extract and obtain knowledge from a large volume of data. This makes ML a promising tool for future ASD research and clinical endeavors suggesting possible avenues for improving ASD screening, diagnostic and therapeutic tools.
The MAO enzyme which is presented in the brain and peripheral tissues and is a significant enzyme that is responsible for the deamination of biogenic amines and thus regulation of neurotransmitter levels. The reaction of these neurotransmitters with MAO enzyme produces aldehyde and free amine. MAO enzyme consists of two isoforms, MAO-A and MAO-B, which are characterized by amino acid sequence, three-dimensional structure, substrate preference and inhibitor selectivity. Dopamine, tyramine, and tryptamine are substrates of both MAO isoforms and MAO inhibitors such as clorgiline, selegiline that are used as medications in neurodegenerative and neurological diseases. In particular, MAO-A inhibitors are used in the treatment of depression, while MAO-B inhibitors are used in the treatment of Parkinson's disease. It is also investigated whether MAO-B inhibitors are effective in the treatment of Alzheimer's disease. Nowadays, life expectancy has increased; as a result, neurodegenerative diseases such as Parkinson'so explain the multifaceted MAO-B inhibitor molecules.
A growing body of evidence suggests that Hsp70, which is overexpressed in human breast tumors, plays a role in tumorigenesis and tumor progression in breast cancer as well as in its aggressive phenotypes. Hsp70 constitutes a potential therapeutic target in the treatment of this disease.

We developed a new series of rhodacyanine-based Hsp70 inhibitors, represented by compounds 1 and 6, in which the cationic pyridin-1-ium or thiazol-3-ium ring of existing Hsp70 inhibitors (e.g., JG-40 and JG-98) was replaced by a corresponding benzo-fused N-heterocycle.

Several lines of evidence suggest that these benzo-fused derivatives may exert their antitumor activities, in part, by targeting Hsp70. These putative inhibitors displayed differential antiproliferative efficacy against breast cancer cells (IC50 as low as 0.25 µM) versus nontumorigenic MCF-10A breast epithelial cells (IC50 ≥ 5 µM). This was correlated with the corresponding Hsp70 expression levels. Using a protein refolding assay, we confirmed that these ashowed improved microsomal stability, these results suggest the translational potential of these putative Hsp70 inhibitors to foster new strategies for cancer therapy. However, whether these benzo-fused rhodacyanines act on kinases or other targets remains unclear, which is currently under investigation.
