Annulated C-beta-D-glucopyranosyl heterocycles were synthesized and tested as inhibitors of glycogen phosphorylase. 2-(beta-D-Glucopyranosyl)-1H-imidazo[4,5-b] pyridine was formed by ring-closure of O-perbenzoylated C-beta-D-glucopyranosyl formic acid with 2,3-diaminopyridine in the presence of triphenylphosphite. Cyclisations of bromomethyl 2,3,4,6-tetra-O-benzoyl-beta-D-glucopyranosyl ketone with a set of 2-aminoheterocycles resulted in constitutionally reversed C-beta-D-glucopyranosyl imidazoles fused by pyridine, pyrimidine, thiazole, 1,3,4-thiadiazole, benzothiazole and benzimidazole. O-Debenzoylation of the above compounds was effected by standard transesterification to get the test compounds. The 1H-imidazo[4,5-b] pyridine proved to be a low micromolar inhibitor (K-i = 21.1 mu M) of rabbit muscle glycogen phosphorylase b, while the other heterocycles displayed weak or no inhibition against the same enzyme.

In higher plants, floral signals are mainly collected and transduced to FLOWERING LOCUS T (FT) in Arabidopsis and its orthologues. The movement of FT from leaves to the shoot apical meristem (SAM) is partially mediated by FT-INTERACTING PROTEIN1 (FTIP1). Although the functions of OsFTIP1 in rice and DOFTIP1 in orchid in FT transport have also been investigated, the FTIP1 homologue in lotus (Nelumbo nucifera Gaertn.), a type of horticultural plant with high economic and cultural value, has not been isolated, and the mechanism of NnFT1 transport has not been explored. Here, we revealed that NnFTIP1 mediates the transport of NnFT1 in ectopic transgenic lines in Arabidopsis. Overexpression of NnFTIP1 in the ftip1-1 background rescued the late flowering phenotype of ftip1-1, indicating that NnFTIP1 has a conserved function as FTIP1. NnFTIP1 and NnFT1 share similar tissue expression patterns and subcellular localization. NnFTIP1 and NnFT1 interact both in vitro and in vivo. In addition, NnFTIP1 affects NnFT1 transport from leaves to the SAM. Furthermore, we found that NnUOF8, a MYB-like transcription factor, directly regulates the expression of NnFTIP1. Our results suggest that the functions of FTIP1 and FT are conserved during evolution in flowering plants.

Background: Presently, rise in the infectious diseases and subsequent development of drug resistance, is a global threat to human health. However, much efforts are being made by scientists, to develop novel antimicrobials, and also to improve the efficacy of available drugs, in order to combat the life-threatening infections. Objective: Synthesis and characterization of azole functional polymer systems for antimicrobial applications. Materials and Methods: Poly(glycidyl methacrylate) (PGMA), was produced by free radical polymerization of the monomer, glycidyl methacrylate (GMA). Different azole functional PGMAs were produced, through chemical modification with imidazole (Im), 1H-1,2,4-triazole (Tri) and 3-amino-1,2,4-triazole (ATri), to get PGMA-Imi, PGMA-Tri and PGMA-ATri, respectively. The structure was confirmed by Fourier transform infrared spectroscopy (FT-IR), thermal properties were investigated by Thermogravimetric Analysis (TGA), and surface morphology was studied by scanning electron microscopy (SEM). Newly synthesized derivatives were further explored, for their antibacterial and anticandidal activities. Results: All the three synthesized and characterized derivatives, displayed a significant activity against the tested microorganisms. The minimum inhibitory concentration (MIC) and minimum bactericidal/fungicidal concentration (MBC/MFC), recorded against Staphylococcus aureus (S. aureus), was 0.5 &1mg/ml for PGMA-Imi, followed by PGMA-ATri & PGMA-Tri, respectively, followed by E. coli with, 1 & 2 mg/ml, 4 & 8 mg/ml, 4& 8 mg/ml, respectively, whereas the maximum MIC & MFC was recorded against C. albicans i.e., 8 & 16 mg/ml, 4 & 8 mg/ml ,4 & 8 mg/ml for PGMA-ATri, PGMA-Tri, PGMA-Imi, respectively. Conclusion: In the present work, we report on the state-of-the-art, azole functional polymer systems for antimicrobial applications. These findings suggest that the synthesized azole functional polymer films have antimicrobial properties, which could be potential candidates for coating applications in the biomedical and wastewater treatment field.

Little is known about the factors regulating carotenoid biosynthesis in flowers. Here, we characterized the REDUCED CAROTENOID PIGMENTATION2 (RCP2) locus from two monkeyflower (Mimulus) species, the bumblebee-pollinated species Mimulus lewisii and the hummingbird-pollinated species Mimulus verbenaceus. We show that loss-of-function mutations of RCP2 cause drastic down-regulation of the entire carotenoid biosynthetic pathway. The causal gene underlying RCP2 encodes a tetratricopeptide repeat protein that is closely related to the Arabidopsis (Arabidopsis thaliana) REDUCED CHLOROPLAST COVERAGE proteins. RCP2 appears to regulate carotenoid biosynthesis independently of RCP1, a previously identified R2R3-MYB master regulator of carotenoid biosynthesis. We show that RCP2 is necessary and sufficient for chromoplast development and carotenoid accumulation in floral tissues. Simultaneous down-regulation of RCP2 and two closely related paralogs, RCP2-L1 and RCP2-L2, yielded plants with pale leaves deficient in chlorophyll and carotenoids and with reduced chloroplast compartment size. Finally, we demonstrate that M. verbenaceus is just as amenable to chemical mutagenesis and in planta transformation as the more extensively studied M. lewisii, making these two species an excellent platform for comparative developmental genetics studies of closely related species with dramatic phenotypic divergence.

Chemical transformations of chromone-3-carbonitrile (1) with some substituted hydrazines, namely, thiosemicarbazide, S-methyl/benzyldithiocarbazate, 7-chloro-4-hydrazinoquinoline, and 3-hydrazino-5,6-diphenyl-1,2,4-triazine, led to substituted pyrazoles 2, 5-8. Ring opening of carbonitrile 1 followed by recyclization with 3-amino-1,2,4-triazole and 2-aminobenzimidazole gave triazolo[1,5-a]pyrimidine 9 and pyrimido[1,2-a]benzimidazole 10, respectively. Treatment of carbonitrile 1 with some heterocyclic amines produced 2-amino-3-substituted-chromones 11 and 12. The novel 3-hydroxychromeno[4,3-b]pyrazolo[4,3-e]pyridin-5(1H)-one (13) was efficiently synthesized from the ring conversion of carbonitrile 1 with cyanoacetohydrazide. A mixture of chromeno[2,3-b]naphthyridine 14 and chromeno[4,3-b]pyridine 15 was obtained from base catalyzed transformation of carbonitrile 1 with malononitrile dimer. A diversity of novel annulated chromeno[2,3-b]pyridines 16-22 was also synthesized. Chromeno[2,3-b]pyrrole-2-carboxylate 23 was obtained from the reaction of carbonitrile 1 with ethyl chloroacetate. Structures of the new synthesized products were deduced on the basis of their analytical and spectral data.

Development of the neurovascular unit (NVU) is a complex, multistage process that requires orchestrated cell signaling mechanisms across several cell types and ultimately results in formation of the blood-brain barrier. Typical high-throughput screening (HTS) assays investigate single biochemical or single cell responses following chemical insult. As the NVU comprises multiple cell types interacting at various stages of development, a methodology combining high-throughput results across pertinent cell-based assays is needed to investigate potential chemical-induced disruption to the development of this complex cell system. To this end, we implemented a novel method for screening putative NVU disruptors across diverse assay platforms to predict chemical perturbation of the developing NVU. HTS assay results measuring chemical-induced perturbations to cellular key events across angiogenic and neurogenic outcomes in vitro were combined to create a cell-based prioritization of NVU hazard. Chemicals were grouped according to similar modes of action to train a logistic regression literature model on a training set of 38 chemicals. This model utilizes the chemical-specific pairwise mutual information score for PubMed MeSH annotations to represent a quantitative measure of previously published results. Taken together, this study presents a methodology to investigate NVU developmental hazard using cell-based HTS assays and literature evidence to prioritize screening of putative NVU disruptors towards a knowledge-driven characterization of neurovascular developmental toxicity. The results from these screening efforts demonstrate that chemicals representing a range of putative vascular disrupting compound (pVDC) scores can also produce effects on neurogenic outcomes and characterizes possible modes of action for disrupting the developing NVU.

Herein, a novel and sensitive fluorescence method for cartap determination is established on the basis of the inner filter effect (IFE) of gold nanoparticles (Au NPs) on the fluorescence of glutathione protected Cu NCs (GSH-Cu NCs). In the presence of Au NPs, the fluorescence of GSH-Cu NCs was strongly quenched by the IFE because the absorption spectra of Au NPs overlap well with the emission spectra of GSH-Cu NCs. Upon addition of cartap, cartap could induce the aggregation of Au NPs whose absorption spectrum does not overlap with the emission spectrum of GSH-Cu NCs. Then, with the increase in cartap concentration, the IFE-decreased fluorescence was gradually recovered, realizing the fluorescence sensing of cartap. Under optimal conditions, the proposed method has a good linear relationship with cartap concentration in the range of 7-100 nM, and the detection limit is 3.34 nM. In addition, satisfactory results were obtained for cartap analysis using tap water and cabbage as real samples, which demonstrated that the method as-developed would have great practical application prospects.

Methylation of 3-amino-1,2,4-triazole and 1-methyl-3-nitro-1,2,4-triazole provides access to three NHC-precursors. For the nitro compound only a monomethylation to the triazolium salt 3(OTf) is observed. The aminotriazole could be subsequently converted to mono- and dicationic carbene precursors 1I and 2(OTf)(2), respectively. The nitro group on NHC 3 leads to a decrease of donor strength and a slightly enhanced acceptor character as compared to a related NHC lacking the nitro group. The cationic NHC 2 is the poorest donor within the series and shows a TEP value of 2072 cm(-1). The properties of this species are dominated by its cationic nature while the influence of the NMe2 group is surprisingly small. X-ray diffraction studies suggest a guanidinium-like character for the NMe2 substituted compounds. (C) 2020 Elsevier B.V. All rights reserved.
