Adult SCs, including mesenchymal stem cells (MSCs), can likewise participate in self-renewal and multilineage differentiation. MSCs are capable of differentiating into osteoblasts, adipocytes or chondrocytes. A third goal of this Perspective is to describe differentiation of MSCs into chondrogenic and osteogenic lineages. Small molecules can stimulate MSCs to specific cell fate both in vitro and in vivo. In this Perspective, some recent examples of applying small molecules for osteogenic and chondrogenic cell fate determination are summarized. Underlying molecular mechanisms and signaling pathways involved are described. Small molecule-based modulation of stem cells shows insight into cell regulation and potential approaches to therapeutic strategies for MSC-related diseases.

Glucose-6-phosphate isomerase (G6PI) catalyses the second step in glycolysis in the reversible interconversion of an aldohexose glucose 6-phosphate, a six membered ring moiety to a ketohexose, fructose 6-phosphate five membered ring moiety. This enzyme is of utmost importance due to its multifunctional role like neuroleukin, autocrine motility factor, etc. in various species. G6PI from Pseudomonas aeruginosa is less explored for its moonlighting properties. These properties can be predicted by studying the active site conservation of residues and their interaction with the specific ligand.

Here, we study the G6PI in a self-inducible construct in bacterial expression system with its purification using Ni-NTA chromatography. The secondary structure of pure G6PI is estimated using circular dichroism to further predict the proper folding form of the protein. The bioactivity of the purified enzyme is quantified using phosphoglucose isomerase colorimetric kit with a value of 12.5 mU/mL. Actinomycin D mw Differential scanning fluorimetry and isothermal titration calorimetry were employed to monitor the interaction of G6PI with its competitive inhibitor, erythrose 4-phosphate and calculated the Tm, Kd and IC50 values. Further, the homology model for the protein was prepared to study the interaction with the erythrose 4-phosphate. MD simulation of the complex was performed at 100 ns to identify the binding interactions.

We identified hydrogen bonds and water bridges dominating the interactions in the active site holding the protein and ligand with strong affinity.

G6PI was successfully crystallized and data has been collected at 6Å. We are focused on improving the crystal quality for obtaining higher resolution data.

The increasing and inappropriate use of antibiotics has increased the number of multidrug-resistant microorganisms to these drugs, causing the emergence of infections that are difficult to control and manage by health professionals. As an alternative to combat these pathogens, some monoterpenes have harmful effects on the bacterial cell membrane, showing themselves as an alternative in combating microorganisms. Therefore, the positive enantiomer α -pinene becomes an alternative to fight bacteria, since it was able to inhibit the growth of the species Escherichia coli ATCC 25922, demonstrating the possibility of its use as an isolated antimicrobial or associated with other drugs.

The aim of this study is to evaluate the sensitivity profile of E. coli ATCC 25922 strain against clinical antimicrobials associated with (+) -α-pinene and how it behaves after successive exposures to subinhibitory concentrations of the phytochemicals.

The minimum inhibitory concentration (MIC) was determined using the microdilunce of some type of existing toxicity reaction related to the herbal medicine and to understand the resistance mechanisms acquired by the microorganism.Benzothiazole is a heterocyclic aromatic and bicyclic compound in which, benzene ring is attached with thiazole ring. This nucleus is established in marine as well as terrestrial natural compounds. The benzothiazole skeleton is established in a broad variety of bioactive heterocycles and natural products. The benzothiazole nucleus is considered as the principle moiety in several biologically active compounds. Thus, over the decade, chemists are more and more paying attention towards the revision on the biological and therapeutic activities such including antimicrobial, analgesic, antininflammatory, antitubercular, antiviral and antioxidant of benzothiazole containing compounds. Additionally, the molecular structures of a number of potent drugs including Frentizole, Pramipexole, Thioflavin T and Riluzole etc are based on benzothiazole skeleton. The present work is the compilation and presentation of all available information in a systematic manner with an aim to present the findings in a way, which may be beneficial for future research.

The combination therapy of HMG-CoA reductase inhibitors (statins), which are anti-hyperlipidemia agents, and fibrates may increase the risk of hepatic dysfunction and myopathy, so this combination required careful administration for patients. In the present study, we evaluated the effects of combination therapy of pemafibrate, a novel fibrate and statins.

We administered pemafibrate for 6 months as an add-on to statin therapy in 27 type 2 diabetes patients with dyslipidemia already receiving statins for 6 months (combination group), and examined the efficacy and safety of the combination therapy in comparison with a pemafibrate monotherapy group.

In the combination group, decrease in serum total cholesterol levels was observed after 6 months of pemafibrate treatment compared to baseline, along with increase in HDL-cholesterol. While serum triglyceride level reduced, HbA1c level was elevated in both the groups. Serum creatinine kinase level, which is an indicator of myopathy, was lowered in the combination group. In addition, decrease in -glutamyl transpeptidase, a parameter of hepatic dysfunction, was observed in the combination group.

The statin-pemafibrate combination therapy in type 2 diabetes patients with dyslipidemia improved lipid metabolism safely without increasing the risk of hepatic dysfunction and myopathy.
