Important Late-Stage Symbiotic Role of the Sinorhizobium meliloti Exopolysaccharide Succinoglycan

Sinorhizobium meliloti enters into beneficial symbiotic interactions with Medicago species of legumes. Bacterial exopolysaccharides play critical signaling roles in infection thread initiation and growth during the early stages of root nodule formation. After endocytosis of S. meliloti by plant cells in the developing nodule, plant-derived nodule-specific cysteine-rich (NCR) peptides mediate terminal differentiation of the bacteria into nitrogen-fixing bacteroids. Previous transcriptional studies showed that the intensively studied cationic peptide NCR247 induces expression of the exo genes that encode the proteins required for succinoglycan biosynthesis. In addition, genetic studies have shown that some exo mutants exhibit increased sensitivity to the antimicrobial action of NCR247. Therefore, we investigated whether the symbiotically active S. meliloti exopolysaccharide succinoglycan can protect S. mehloti against the antimicrobial activity of NCR247. We discovered that high-molecularweight forms of succinoglycan have the ability to protect S. meliloti from the antimicrobial action of the NCR247 peptide but low-molecular-weight forms of wild-type succinoglycan do not. The protective function of high-molecular-weight succinoglycan occurs via direct molecular interactions between anionic succinoglycan and the cationic NCR247 peptide, but this interaction is not chiral. Taken together, our observations suggest that S. meliloti exopolysaccharides not only may be critical during early stages of nodule invasion but also are upregulated at a late stage of symbiosis to protect bacteria against the bactericidal action of cationic NCR peptides. Our findings represent an important step forward in fully understanding the complete set of exopolysaccharide functions during legume symbiosis. IMPORTANCE Symbiotic interactions between rhizobia and legumes are economically important for global food production. The legume symbiosis also is a major part of the global nitrogen cycle and is an ideal model system to study host-microbe interactions. Signaling between legumes and rhizobia is essential to establish symbiosis, and understanding these signals is a major goal in the field. Exopolysaccharides are important in the symbiotic context because they are essential signaling molecules during early-stage symbiosis. In this study, we provide evidence suggesting that the Sinorhizobium meliloti exopolysaccharide succinoglycan also protects the bacteria against the antimicrobial action of essential late-stage symbiosis plant peptides.

A microporous, amino acid functionalized Zn(ii)-organic framework nanoflower for selective CO2 capture and solvent encapsulation

A new homochiral metal organic framework, {[Zn-4(mu(3)-OH)(2)(d-2,4-cbs)(2)(H2O)(4)].5H(2)O}(n) (Zn-CBS), has been solvothermally synthesized using a new chiral amino acid based tricarboxylic acid ligand, (2-((4-carboxybenzyl)amino)succinic acid), H-3(d-2,4-cbs). Zn-CBS was characterized by various techniques like Fourier transform infrared spectroscopy (FTIR), UV-Vis solid-state diffuse reflectance spectroscopy, elemental microanalysis, thermogravimetric analysis (TGA), powder X-ray diffraction (PXRD), field emission scanning electron microscopy (FESEM), high resolution transmission electron microscopy (HRTEM), and energy dispersive X-ray analysis (EDX) and elemental mapping. The nanoflower arrangement in Zn-CBS is clearly seen from the FESEM and TEM images. Its microporous nature is established by the nitrogen adsorption measurements which exhibit a reversible type I isotherm with a BET surface area of 282 m(2) g(-1). Similarly, it shows a reversible type I isotherm for H-2 with an uptake of 0.5 wt% at 77 K. Based on its CO2 sorption isotherm with an uptake of 85.9 cm(3) g(-1) at 195 K, a high isosteric heat of adsorption (Q(st)) of 35 kJ mol(-1) at zero coverage is obtained. This is illustrated by its high potential of selectivity towards CO2 over N-2 and CH4 under ambient conditions (298 K and 1 bar). With the help of configurational bias Monte Carlo molecular simulation, this selectivity is explained for an effective interaction between CO2 and basic amine sites of the framework. The porous nature and functionality of Zn-CBS have also been utilized in encapsulating various small molecules, which is followed by FTIR, TGA and PXRD.

Efforts Toward a Unified Kainoid Family Synthesis Approach: Unexpected Sulfinamide-Directed Conjugate Addition Results

A short asymmetric synthesis of an all-syn and all-trans kainoid core is reported. The synthetic route relies on the application of a new asymmetric [3+2] annulation reaction followed by a conjugate addition reaction to install this kainoid’s three stereocenters. A surprising intramolecular conjugate addition enabled by the chiral tert-butylsulfinyl group residing on the 3-pyrroline nitrogen atom surpassed its expected role as a steric spectator. Efforts to outcompete intramolecular 1,4-addition by further oxidizing the sulfoxide, or use of additives, and advancement of the all-syn addition product to the requisite kainoid common core are detailed.

Design and preparation of mesoporous silica carriers with chiral structures for drug release differentiation

In this study, twisted rod-like chiral mesoporous silicas (CMSs) with discriminating chiral characteristics (D/L) were designed and biomimetic synthesized by using L- and D-alanine derivatives as templates, and employed as poorly water-soluble chiral drug ibuprofen (IBU) carriers. The morphology and mesoscopic characteristics of CMSs were determined by transmission electron microscope (TEM) and small-angle X-ray scattering (SAXS). Meanwhile, the physicochemical properties of CMSs before and after drug loading were systematically characterized by infrared spectroscopy (IR), nitrogen adsorption, X-ray diffraction (XRD), differential scanning calorimetry (DSC) and induced circular dichroism (ICD). The results suggested that, the CMSs exhibited local chiral characteristics, which were successfully endowed by the alanine-derivative surfactants templates with a reversal of chirality. The crystalline state of IBU was effectively converted to amorphous state after being incorporated into CMSs, and the drug delivery systems shared the chiral characteristic of carriers. Besides, in vitro drug release experiments were respectively performed in simulated gastric fluid (SGF, pH 1) and simulated intestinal fluid (SIF, pH 6.8) medium, and the results demonstrated that both L-CMS and D-CMS could improve the dissolution of IBU in SGF medium, which could be explained by the amorphization of IBU. Particularly, due to the different pore geometry of these two materials, CMSs with different chirality (D/L) could be applied as carriers to accomplish drug release differentiation.

CHEMOSELECTIVITY-TUNABLE [5+2] CYCLOADDITIONS OF ALLENAMIDES AND OXIDOPYRYLIUMS

[5 + 2] Cycloadditions between allenamides and oxidopyryliums are described. A series of substituted cycloheptanones were synthesized by this method with moderate to good yields. Interestingly, the chemoselectivity of this reaction could be tuned by changing the electron-withdrawing groups on the allenamide nitrogen atom. When oxazolidinone chiral auxiliaries were introduced in the allenamide substrate, [5 + 2] cycloadducts could be obtained with high diastereoselectivities. This reaction provides a useful synthetic protocol for the construction of highly substituted seven-membered rings.

Enantioselective approach to indolizidine and quinolizidine scaffolds. Application to the synthesis of peptide mimics

An enantioselective approach to substituted indolizidine and quinolizidine frameworks has been developed. Key steps of the synthesis are the enantioselective, palladium-catalyzed N-allylation of an imide, the nucleophilic allylation of an acyliminium ion and a ring closing metathesis. This general strategy has been applied to the synthesis of indolizidine peptide mimics, starting from a chiral imide derived from L-aspartic acid. It was observed that the preexisting stereogenic center of this substrate has a moderate influence on the stereoselectivity of the electrophilic allylation, which is mainly determined by the sense of chirality of the catalyst.

Methods for Synthesis of Chiral Alcohols and Their Conversion to Heterocycles Containing Bi-2-Naphthyl Moiety

Convenient methods were developed for the preparation of chiral alcohols containing bi-2-naphthyl moiety in 92-96% yields. The substituted 1,4-diols containing bi-2-naphthyl moiety were further converted to N-substituted pyrrolidine derivatives in 72%-76% yields via the corresponding dimesylate followed by reaction with primary amines. Interestingly, the corresponding chiral tetrahydrofuran derivative was obtained in 90% yield by self condensation of the dimesylate in the absence of primary amines.
