Phytochemical Repurposing of Natural Molecule: Sabinene for Identification of Novel Therapeutic Benefits Using In Silico and In Vitro Approaches

Repurposing of drugs/natural or synthetic chemicals is a promising approach to identify the new therapeutic indication/use and mode of action. In pharmaceuticals, this process is used to save the time and cost for the drug discovery process with reduced risk of failure. In the present studies, repurposing of a natural molecule: sabinene (major phytochemical in cardamom) was used to characterize the new biological activities using in silico as well as in vitro approaches. In silico similarity searching demonstrated that (+)-3-carene possessed the maximum structural similarity with sabinene. In vitro activities of (+)-3-carene were repurposed for sabinene based on similarity hypothesis (similar structures may have similar biological activities). In vitro studies demonstrated that sabinene is having antimicrobial activity and also showed concentration-dependent antioxidant activity by 2,2-diphenyl-1-picrylhydrazyl scavenging assay. Sabinene treatment protected the yeast cells from hydrogen peroxide-induced cytotoxicity in 3-(4,5-dimethylthiazole-2-yl)-2,5-diphenyltetrazolium bromide assay. Moreover, it was found that sabinene treatment decreased the generation of oxidative stress and also decreased the activities of antioxidant enzymes; glutathione S-transferase, catalase, and lipid peroxidase as compared with untreated yeast cells. Sabinene was also found to have angiostatic and antiangiogenic effects. These results were supported by molecular docking studies against antiangiogenic targets. Therefore, the results of these studies suggested that structurally similar molecules are having the same activity. The phytochemical repurposing using in silico similarity searching as well as in vitro approaches can also be applied for other phytochemicals whose activities are not/less known. Furthermore, this could also be useful in the novel lead/scaffold discovery and target fishing.

A general asymmetric copper-catalysed Sonogashira C(sp(3))-C(sp) coupling

Continued development of the Sonogashira coupling has made it a well established and versatile reaction for the straightforward formation of C-C bonds, forging the carbon skeletons of broadly useful functionalized molecules. However, asymmetric Sonogashira coupling, particularly for C(sp(3))-C(sp) bond formation, has remained largely unexplored. Here we demonstrate a general stereoconvergent Sonogashira C(sp(3))-C(sp) cross-coupling of a broad range of terminal alkynes and racemic alkyl halides (>120 examples) that are enabled by copper-catalysed radical-involved alkynylation using a chiral cinchona alkaloid-based P,N-ligand. Industrially relevant acetylene and propyne are successfully incorporated, laying the foundation for scalable and economic synthetic applications. The potential utility of this method is demonstrated in the facile synthesis of stereoenriched bioactive or functional molecule derivatives, medicinal compounds and natural products that feature a range of chiral C(sp(3))-C(sp/sp(2)/sp(3)) bonds. This work emphasizes the importance of radical species for developing enantioconvergent transformations.

Monitor application of multi-electrochemical sensor in extracting bromine from seawater

In this paper, a set of online measurement devices of multi-electrochemical sensor was investigated. Combined with industrial distributed control system, it was first applied in extracting bromine from seawater to realize the real-time adjustment of production process parameters. In the process of extracting bromine from seawater, the pH value of acidified raw brine, the addition amount of Cl-2 in the oxidation stage and the addition amount of SO2 in the absorption stage are key parameters to control the whole production process. The multi-electrochemical sensor realized a rapid and high-throughput detection of the above parameters by integrating an all-solid-stage bromide ion selective electrode (Br-ISE), Eh electrode and pH electrode. The Br-ISE and the pH electrode were self-developed electrodes and the Pt electrode was Eh electrode. The pH electrode was used to control the addition amount of H2SO4 during the acidification of the brine. The Eh electrode was used to control the addition amount of Cl-2 during the oxidation stage and the addition amount of SO2 during the absorption stage. The Br-ISE was used to monitor the Br- concentration change in the raw brine. Results showed the optimum range of Eh in the oxidation stage and absorption stage of brine were 950-1000 mV and 580-610 mV, respectively. The application of multi-electrochemical sensor in industrial bromine production can realize real-time control of material addition and save the cost of production.

Determination of optimum metam-potassium rate for weed, tomato, and pepper termination

Metam potassium (metam-K) is a soil fumigant used commonly in Florida at the end of the tomato and pepper production season. The fumigant essentially cleans a field by killing the established weeds and crops after harvest. The goal of this project was to determine the optimal rate of metam-K for the effective termination of tomato, pepper, and established weeds such as purple nutsedge, goosegrass, and dogfennel. Tomato, pepper, and purple nutsedge at bed center were effectively terminated with the metam-K rate of 65 kg ha(-1). Optimal rates required for the termination of goosegrass and dogfennel were 91 and 156 kg ha(-1), respectively. In contrast, metam-K at 500 to 680 kg ha(-1) was required to terminate purple nutsedge on bed edges. The reduced efficacy of metam-K at bed edge might be related to the limited movement of metam-K in soil.

Improved catalytic performance of mesoporous ZSM-5 nanocrystalline zeolite prepared by the cationic surfactant-ammonium salt mixed agent method in the methanol to gasoline reaction

A mixed organic agent system was employed to achieve mesoporous highly crystalline ZSM-5 zeolite. Decyltrimethylammonium bromide (DeTAB) and tetramethyl ammonium hydroxide (TMAOH) were used as the mesogenous and molecular templates respectively in the synthesis gel with a composition of 60SiO(2): 1Al(2)O(3):12Na(2)O:3150H(2)O:xDeTAB:8TMAOH. The sole presence of DeTAB as the mesogenous template in the synthesis gel led to the high degrees of mesoporosity in the ZSM-5/xD samples but negatively affected the intrinsic properties of zeolites. At the high concentration of DeTAB (x = 0.7), the mesopore volume dramatically increased while the relative crystallinity and the total acid sites critically decreased. By adding the TMA(+) ions as a microporous template to the ZSM-5/0.7D synthesis gel, not only a zeolite with well-developed mesoporosity was obtained but also its crystal structure and the intrinsic acidity were preserved. The catalyst samples were characterized by FESEM, TEM, XRD, FT-IR, nitrogen adsorption-desorption isotherms, NH3-TPD and TGA techniques. The ZSM-5/0.7D/T exhibited higher surface area, higher mesopore volume, higher crystallinity and more acid sites than the ZSM-5/0.7D. The catalytic conversion of methanol to gasoline was conducted in a fixed bed reactor at T = 390 degrees C and WHSV = 4.74 h(-1). In ZSM-5/0.7D/T catalyst the mesoporosity formation without severely damaging the crystal structure and the acidity of the zeolite led to the best catalytic performance including the highest liquid hydrocarbon yield, most stable catalytic performance and longest catalytic lifetime.

Innovative composite sorbent for thermal energy storage based on a SrBr2 center dot 6H(2)O filled silicone composite foam

This paper reports about the first experimental activity on a composite material for thermal energy storage, based on a SrBr2 center dot 6H(2)O filled silicone foam. The morphological and thermal features of the composite with different salt content (i.e. between 40 wt.% and 70 wt.%) were investigated. The dehydration behavior was studied by thermo-gravimetric analysis. Furthermore, scanning electron and 3D optical microscopy were used to compare the cellular microstructure of the composite foams. The synthesized foams are characterized by a well-interconnected cellular structure with a three-dimensional porous network. This, together with the high permeability to water vapor of the matrix favors water vapor diffusion and allows the reaction of all the salt embedded in the matrix. The main advantages of the composite material were analyzed and compared to other composites in literature. Since the production process, especially for higher salt content, seemed not sufficiently effective, causing a reduced foaming ration and lower ability to incorporate the salt hydrate, possible improvements were proposed and discussed.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 3081-61-6. Recommanded Product: 3081-61-6.

Gatifloxacin-Ionic Surfactant Interactions: Volumetric, Acoustic, Voltammetric, and Spectroscopic Studies

Surfactant systems have been frequently used as pseudomodels for investigating interactions of drugs with biological membranes because of their structural similarities with the latter. This helps to understand complicated yet very important biological processes like diffusion of bioactive moieties through biomembranes. The current study deals with voltammetric and spectroscopic studies to evaluate the interaction of a potential antibacterial drug, gatifloxacin (GTF), with a cationic surfactant, dodecyltrimethylammonium bromide (DTAB), and an anionic surfactant, sodium dodecyl sulfate (SDS), under physiological conditions (phosphate buffer, pH 7.4). For more detailed insight into the GTF-ionic surfactant interactions, density and acoustic data were also recorded and used to calculate several important parameters, namely, apparent molar volume (x278;(V)), isentropic compressibility (K-s), and apparent molar isentropic compressibility (x278;(K)) at T = 298.15, 303.15, 308.15, and 313.15 K. Values for partial molar volume (x278;Vo), partial molar expansivity x278;Eo, specific acoustic impedance (Z), relative association (RA), intermolecular free length (L-f), and sound velocity number (U) were also obtained. The interpretation of the concentration dependence of the above-mentioned quantities using a cosphere overlap model led to a better apprehension of solute-solute and solute-solvent intermolecular interactions present in the investigated system, whereas cyclic voltammetry and ultra violet (UV)-visible spectroscopic studies assisted in predicting the location of adsorbed GTF molecules within the DTAB and SDS micelles.

Potential use of 13-mer peptides based on phospholipase and oligoarginine as leishmanicidal agents

Phospholipase A(2) toxins present in snake venoms interact with biological membranes and serve as structural models for the design of small peptides with anticancer, antibacterial and antiparasitic properties. Oligoarginine peptides are capable of increasing cell membrane permeability (cell penetrating peptides), and for this reason are interesting delivery systems for compounds of pharmacological interest. Inspired by these two families of bioactive molecules, we have synthesized two 13-mer peptides as potential antileishmanial leads gaining insights into structural features useful for the future design of more potent peptides. The peptides included p-Acl, reproducing a natural segment of a Lys49 PLA(2) from Agkistrodon contortrix laticinctus snake venom, and its p-AclR7 analogue where all seven lysine residues were replaced by arginines. Both peptides were active against promastigote and amastigote forms of Leishmania (L.) amazonensis and L. (L.) infantum, while displaying low cytotoxicity for primary murine macrophages. Spectrofluorimetric studies suggest that permeabilization of the parasite’s cell membrane is the probable mechanism of action of these biomolecules. Relevantly, the engineered peptide p-AclR7 was more active in both life stages of Leishmania and induced higher rates of ethidium bromide incorporation than its native template p-Acl. Taken together, the results suggest that short peptides based on phospholipase toxins are potential scaffolds for development of antileishmanial candidates. Moreover, specific amino acid substitutions, such those herein employed, may enhance the antiparasitic action of these cationic peptides, encouraging their future biomedical applications.

Removal of iodides and bromides at parts per million concentrations using a novel bismuth composite material

Iodide and bromide ions in surface and ground waters (typically less than 0.05 mg/L for iodide and 0.5 mg/L for bromide) could react with natural organic matters under oxidative disinfection process and produce toxic disinfectant by-products. Therefore, removal of iodides and bromides in water treatment is desirable for improving drinking water quality. We have synthesized a micro-nano Bi2O3-Bi2S3 composite via a carbogenic sphere-supported synthesis strategy. A hydrothermal processing of sucrose resulted in uniform spherical carbogenic microspheres, which served as an excellent substrate for reaction between Bi(NO3)(3) and Na2SO4 in emulsion, forming Bi2O3-Bi-2(SO4)(3) composites, which was then converted into Bi2O3-Bi2S3 after calcination. Using 8 g/L of this material Bi2O3-Bi2S3, 87.69% of iodide at an initial concentration of 0.05 mg/L was removed after 3 h of contact, and 86.38% of bromide at an initial concentration of 0.5 mg/L was removed after 14 h. Such effective removal efficiency was retained when used in artificial groundwater treatment. Overall, this study developed a new method to produce the Bi2O3-Bi2S3 composite in high yield, and the as-synthesized Bi2O3-Bi2S3 composites exhibited high removal efficiencies toward I- and Br- through adsorption mechanism.
