Optical probe for the analysis of trace indole in shrimp

Indole is a chemical from the decomposition of shrimp and is used extensively to indicate seafood freshness. US Food and Drug Administration (FDA) sets its concentration of < 25 mu g/100 g shrimp as the threshold for Class I (fresh shrimp). A novel optical probe is reported to quantitatively analyze trace indole in shrimp, including the Class I threshold concentration. Based on an Ehrlich-type reaction, visible spectroscopic analysis of indole in petroleum ether gives a limit of detection (LoD) and quantification (LoQ) of 0.05 and 0.16 mu g mL(-1), respectively. For 25 mu g indole/100 g shrimp extracted into petroleum ether, the probe successfully detects it and the color change is visible to the naked eye. Analysis of the probe response by a visible spectrometer leads to quantification of <= 25 mu g indole/100 g shrimp, when recovery is accounted for. When a handheld colorimeter, based on the CIELAB color space, and a smartphone with Bluetooth connectivity are used, the probe demonstrates similar sensitivity for indole in shrimp. The current probe is made of 4-(dimethylamino)benzaldehyde (DMAB) and catalyst p-toluenesulfonic acid (PTSA) in thin films. Indole in shrimp samples after extraction reacts with DMAB to give red beta-bis(indolyl)methane.

Mesobacillus aurantius sp. nov., isolated from an orange-colored pond near a solar saltern

An endospore producing, strict aerobic, Gram-stain-positive, orange-colored colony forming bacterium designated as strain JC1013(T) was isolated from an orange pond near a solar saltern of Tamil Nadu, India. Phylogenetic analysis of the 16S rRNA gene sequences indicated that strain was affiliated to the family Bacillaceae of the phylum Firmicutes. Strain showed highest 16S rRNA gene sequence identity of 98.7% with Mesobacillus selenatarsenatis SF-1( T) and below 98.3% with other members of the genus Mesobacillus. Strain JC1013(T) produced carotenoid pigments and indole compounds. Major cellular fatty acids of strain JC1013(T) were iso-C-15:0,C- anteiso-C-15:0, C-16:0 3-OH, iso-C-17:0 omega 10c and summed feature 4 (iso-C-17:1 I/ anteisoB). Polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, two unidentified aminolipids and four unidentified phospholipids. Strain JC1013(T) constituted m-diaminopimelic acid as diagnostic cell wall amino acids. MK-7 is the predominant menaquinone of strain JC1013(T). The genome size of strain JC1013(T) was 4.6 Mbp and its G + C content was 42.7 mol%. For the affirmation of strain’s taxonomic status, a detailed phylogenomic study was done. Based on the phylogenetic analyses, low ANI (84.6%), AAI (88.5%) values, in-silico DDH (< 29%) value, morphological, physiological and chemo-taxonomical characteristics, strain JC1013(T) was clearly distinguished from the nearest phylogenetic neighbor, Mesobacillus selenatarsenatis SF-1(T) to conclude that it is a new species of the genus Mesobacillus. We propose the name as Mesobacillus aurantius with type strain JC1013(T) (= NBRC 114146(T) = KACC 21451( T)).

Design, stereoselective synthesis, computational studies and cholinesterase inhibitory activity of novel spiropyrrolidinoquinoxaline tethered indole hybrid heterocycle

A facile eco-friendly approach for the regioand stereoselective synthesis of structurally intriguing novel spiropyrrolidinoquinoxaline tethered indole hybrid heterocycle has been accomplished via a cascade reaction sequence involving 1,3-dipolar cycloaddition as the key step. Structural elucidation of the synthesized spiroheterocycle was performed by NMR spectroscopy, mass spectrometric analysis and the stereochemistry of asymmetric carbons have been confirmed by single crystal X-ray diffraction analysis. The mechanistic rationalization for the formation of spiroheterocyclic hybrid was investigated through density functional theory (DFT) calculations. In addition, the synthesized spiroheterocyclic hybrid was tested for its cholinesterase inhibitory activity against ChEs and displayed good activity when compared to the standard drug galantamine.

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.

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.

Local and Universal Action: The Paradoxes of Indole Signalling in Bacteria

Indole is a signalling molecule produced by many bacterial species and involved in intraspecies, interspecies, and interkingdom signalling. Despite the increasing volume of research published in this area, many aspects of indole signalling remain enigmatic. There is disagreement over the mechanism of indole import and export and no clearly defined target through which its effects are exerted. Progress is hindered further by the confused and sometimes contradictory body of indole research literature. We explore the reasons behind this lack of consistency and speculate whether the discovery of a new, pulse mode of indole signalling, together with a move away from the idea of a conventional protein target, might help to overcome these problems and enable the field to move forward.

Gold-Catalyzed Oxidative Arylations of 3-Butyn-1-ols and 2-Propyn1-ols with Nitrones to Yield Distinct Fused Indoles Bearing a Heterocyclic Ring

The catalytic formation of various fused indoles from the nitrone oxidations of 1-substituted n-yn-1-ols (n = 2, 3) is described. For 3-butyn-1-ols, the oxidations yield tetrahydropyrano[4,3-b]indoles, whereas 2-propynols deliver tetrahydro-[1,2]oxazino[5,4-b]indoles efficiently. When styryl nitrones were tested on 2-propyn-1-ols, dihydrooxazolo[3,4-a]indoles were produced efficiently. We postulate that the formation of these fused indoles arises from a common mechanism, involving a [3,3]-sigmatropic shift of an initial alkenyl gold intermediate to furnish an oxoarylation before preceding to these fused indoles.
