Encapsulation of nodal segments of Allamanda cathartica for short-term storage and germplasm exchange

Synthetic seed has the potential to be used as a cost-effective tool for propagation and storage of germplasm. In the present study, synthetic seeds were produced by encapsulating nodal segments of Allamanda cathartica in calcium alginate gel. The best gel complex was achieved using 3% sodium alginate and 100 mM calcium chloride (CaCl2 center dot 2H(2)O). Maximum conversion response of encapsulated nodal segments into plantlets was obtained on Murashige and Skoog (MS) medium with 3.0 mu M meta-Topolin (mT) and 0.5 mu M alpha-naphthalene acetic acid (NAA). Encapsulated nodal segments could be stored at low temperature (4 degrees C) up to 6 weeks with a survival frequency of 85%. The regenerated shoots rooted on half-strength MS medium containing 0.5 mu M indole-3-butyric acid (IBA). Plantlets with adequate root and shoot systems were hardened off successfully with 90% success rate. Inter Simple Sequence Repeat (ISSR) markers were used to evaluate genetic stability among synthetic seed derived plantlets. The repeated high regeneration of plants from alginate-coated axillary buds and apparently good viability of the synseeds after four weeks of storage indicate that this is a viable strategy for the exchange of A. cathartica genetic resources. Key Message Synseed technology enhances the efforts of micropropagation and helps in the maintenance of rare, endangered and elite genotypes. Allamanda cathartica possesses high global market value due to the presence of phytoconstituent in leaves and roots of the plant. Plant has ornamental properties for its attractive funnel shaped yellow coloured flowers. Genetic stability of the regenerated plantlets were analyzed using PCR-based molecular markers.

Lewis Acid-Controlled Regioselective Phosphorylation of 2-Indolylmethanols with Diarylphosphine Oxides: Synthesis of Highly Substituted Indoles

The Lewis acid-promoted phosphorylation of 2-indolylmethanols with diarylphosphine oxides is described. The regioselectivity of the reaction can be modulated by the choice of rare earth metal Lewis acid, offering a highly selective approach to structurally diverse indole derivatives in up to 97% yield for over 50 examples. This strategy features high selectivity, good functional group tolerance, and easy scalability. The utility of this method is further highlighted by facile modification of the products to access novel indole-based phosphine ligand.

Mycelial culture extracts of selected wood-decay mushrooms as a source of skin-protecting factors

Objectives This study analyzed the content of substances with cosmetologic properties in the extracts obtained from the mycelial cultures of Ganoderma applanatum, Laetiporus sulphureus, and Trametes versicolor. The effect of these extracts on the inhibition of tyrosinase and hyaluronidase was determined, and their values of sun protection factor (SPF) were calculated. Results The total amount of phenolic acids in the extracts ranged from 2.69 (G. applanatum) to 10.30 mg/100 g dry weight (T. versicolor). The total amount of sterols was estimated at 48.40 (T. versicolor) to 201.04 mg/100 g dry weight (L. sulphureus), and that of indoles at 2.90 (G. applanatum) to 16.74 mg/100 dry weight (L. sulphureus). Kojic acid was determined in the extracts of L. sulphureus and G. applanatum. It was observed that L. sulphureus extract caused dose-dependent inhibition of hyaluronidase, while all the extracts inhibited tyrosinase. The extract of G. applanatum exhibited an SPF value of similar to 9. Conclusions The results showed that the mycelial cultures of the studied species may be used as an alternative source of substances used in cosmetology.

Application of gas sensors for modelling the dynamic growth of Pseudomonas in pork stored at different temperatures

Pseudomonas have a faster growth rate over other bacteria in chilled meat under aerobic conditions. A non-destructive method for modelling the dynamic growth of Pseudomonas in pork stored at different temperatures using gas sensors was presented in our work. Based on selected gas sensor data, the first-order kinetic equations (Gompertz and Logistic Functions) combined with the secondary model (Square-root Function) effectively simulated Pseudomonas growth in pork at different temperatures with R-2 and RMSE values of 0.71-0.97 and 0.27-0.84, respectively. Additionally, these models showed high accuracy with correlation coefficients greater than 0.90, in addition to several individual accuracy values. Furthermore, HS-SPME/GC-MS results demonstrated the presence of identified key volatiles in samples inoculated with Pseudomonas, including three amine compounds (mercaptamine, 1-octanamine and 1-heptadecanamine), phenol and indole. Our work showed that gas sensors are a rapid, easy and non-destructive method with acceptable feasibility in modelling the dynamic growth of spoilage microorganisms in meat.

Mechanochemical synthesis, linear and nonlinear optical properties of a new oligophenyleneimine with indole terminal moiety for optoelectronic application

A quadrupolar D-pi-A-pi-D oligophenyleneimine with indole moiety as terminal group (OIC-I) obtained by a green method of mechanosynthesis was obtained. The molecular structure of OIC-I was elucidated by FTIR and H1 NMR spectroscopies. DFT and TDDFT studies show possible intramolecular charge transfer (ICT) processes and a hyperpolarizability value that suggest a nonlinear behavior, which was verified by Z-scan technique. The linear optical characterization of OIC-I using UV-Vis spectroscopy and fluorescence in solution and solid state exhibits a bathochromic effect by increasing the polarity of the solvent. According to data obtained by the Z-scan technique, OIC-I could be used as a saturable absorb material, and this feature can be applied in nonlinear signal filtering, optical signal processing, and mode locking devices. OIC-I has attractive linear and nonlinear optical properties, good processability in solution, and thermal stability for its potential application as a saturated absorber in optoelectronic devices.

Co(III), Rh(III) & Ir(III)-Catalyzed Direct C-H Alkylation/Alkenylation/Arylation with Carbene Precursors

Metal carbenes play a pivotal role in transition-metal-catalyzed synthetic transfer reactions. The metal carbene is generated either from a diazo compound through facile extrusion of N-2 with a metal catalyst or in situ generated from other sources like triazoles, pyriodotriazoles, sulfoxonium ylides and iodonium-ylide. On the other hand, Co(III), Rh(III) & Ir(III)-catalyzed C-H functionalizations have been well established as a key synthetic step to enable the construction of various synthetic transformations. Interestingly, in recent years, merging of these two concepts C-H activation and carbene migratory insertion gained much attention, in particular group 9 metal-catalyzed arene C-H functionalizations with carbene precursors via carbene migratory insertion. In this review, we summarize recent advances in Co(III), Rh(III) & Ir(III)-catalyzed direct C-H alkylation/alkenylation/arylation with carbene precursors and also discuss key synthetic intermediates within the catalytic cycles.

Biodiversity of Convolvulaceous species that contain ergot alkaloids, indole diterpene alkaloids, and swainsonine

Convolvulaceous species have been reported to contain several bioactive principles thought to be toxic to livestock including the calystegines, swainsonine, ergot alkaloids, and indole diterpene alkaloids. Swainsonine, ergot alkaloids, and indole diterpene alkaloids are produced by seed transmitted fungal symbionts associated with their respective plant host, while the calystegines are produced by the plant. To date, Ipomoea asarifolia and Ipomoea muelleri represent the only Ipomoea species and members of the Convolvulaceae known to contain indole diterpene alkaloids, however several other Convolvulaceous species are reported to contain ergot alkaloids. To further explore the biodiversity of species that may contain indole diterpenes, we analyzed several Convolvulaceous species (n = 30) for indole diterpene alkaloids, representing four genera, Argyreia, Ipomoea, Stictocardia, and Turbina, that had been previously reported to contain ergot alkaloids. These species were also verified to contain ergot alkaloids and subsequently analyzed for swainsonine. Ergot alkaloids were detected in 18 species representing all four genera screened, indole diterpenes were detected in two Argyreia species and eight Ipomoea species of the 18 that contained ergot alkaloids, and swainsonine was detected in two Ipomoea species. The data suggest a strong association exists between the relationship of the Periglandula species associated with each host and the occurrence of the ergot alkaloids and/or the indole diterpenes reported here. Likewise there appears to be an association between the occurrence of the respective bioactive principle and the genetic relatedness of the respective host plant species.

Switchable regioselection of C-H thiolation of indoles using different TMS counterions

A switchable regioselectivity in C-H thiolation reaction by simply swapping the counteranions of TMS is reported here for the first time. An exclusive C3-H thiolation of indoles with sodium arylsulfinates was achieved in the presence of TMSCl as a promoter. In contrast, with the use of TMSOTf instead of TMSCl under otherwise identical conditions, a regiospecific C2-H thiolation of indoles was realized with the same set of substrates.
