New salicylic acid and pyroglutamic acid conjugated derivatives confer protection to bread wheat against Zymoseptoria tritici

BACKGROUND: To promote sustainable agriculture and healthy food, research that contributes towards a new generation of eco-friendly phytosanitary compounds is increasingly encouraged. The plant hormone salicylic acid (SA) is known for its ability to induce resistance in plants against a wide range of pathogens, whereas pyroglutamic acid (PGA), a constrained analogue of gamma-aminobutyric acid, has never been studied in the context of plant protection. RESULTS: The present study investigated for the first time the protection efficacy of SA and PGA and five new conjugated derivatives against Zymoseptoria tritici, the main pathogen in wheat crops. SA and four derivatives showed significant disease severity reductions in planta (up to 49%). In vitro assays revealed that some molecules, including SA, displayed a small direct antifungal activity, whereas others, such as PGA, showed no effect. This finding suggests that, especially for molecules without any direct activity, the mode of action relies mainly on the induction of plant resistance. CONCLUSION: Further investigations are needed to identify the defence pathways involved in plant resistance mechanisms elicited or primed by the molecules. The manufacture of these products was easily achieved on a scale of tens of grams of raw materials, and is easily scalable. The synthetic pathway is simple, short and inexpensive. For all of these reasons, the production of the target molecules is attractive for producers, whereas the prospect of a generation of non-polluting compounds with lasting efficiency against Z. tritici in wheat comes at a key moment for the sustainability of agriculture.

Synthesis of novel phenyl substituted dibenzonaphthyridines

The reaction of 2,4-dichloroquinolines with 2-amino-5-chlorobenzophenone yielded 2-[(2-benzoyl-4-chlorophenyl) amino]-4-chloroquinolines which with sodium methoxide afforded 2-[(2-benzoyl-4-chlorophenyl)amino]-4- methoxyquinolines. These on PPA-catalysed cyclisation gave 2-chloro-12- phenyldibenzo[b,g][1,8]naphthyridin-11(6H)-ones. Temperature differences for the formation of the final products were due to the in situ formation of the 2-[(2-benzoyl-4-chlorophenyl)amino]quinolin-4-ones from the chloro and methoxy intermediates. The dibenzonaphthyridin-11-ones were N-methylated at N(6); a methyl group at C(7) was found to hinder the methylation reaction sterically, when a considerably longer reaction time was needed.

Using human neural progenitor cell models to conduct large-scale drug screens for neurological and psychiatric diseases

High-throughput drug screen (HTS) has become a viable approach for new treatment discovery in human diseases. Advances in gene editing technology and human pluripotent stem cell differentiation techniques have expanded the capability of HTS to identify potential treatments for human diseases of the central nervous system. Here, we describe techniques to use a human patient-derived neural progenitor cell luciferase reporter line to screen a large small molecule library.

Chiral ferrocenylthiazolidines, new ligands for palladium complexes

The reaction of ferrocene with methyl or ethyl esters of L-cysteine in the presence of paraformaldehyde is studied. This process yields the optically pure derivatives: methyl or ethyl (R)-3-(ferrocenylmethyl)thiazolidine-4-carboxylates (1a or 1b), together with the corresponding N,N-bisthiazolidine derivatives (2a or 2b). When the reaction was carried out using the ethyl ester of L-cysteine, small amounts (ca. 9%) of the 1,1′-disubstituted ferrocene derivative (3b) were also isolated. The reactivity of compounds 1 versus palladium(II) species is studied, and has allowed us to isolate and characterise: [Pd(eta3-C3H5)Br(1a)] (4a) and [Pd(eta3-C3H5)Br(1b)] (4b), in which the ferrocenyl ligand behaves as a monodentate S-donor group. Compounds 4 evolve in the presence of dimethylsulfoxide to produce: [Pd(eta1-C3H5)Br(1)(dmso)] (5) in which the palladium(II) is bound to the terminal carbon of the C3H5 group. The reactivity of ligands 1 with Na2[PdCl4] is also reported and has allowed us to isolate the dinuclear compounds [Pd2Cl4(mu-1a)2] (6a) and [Pd2Cl4(mu-1b)2] (6b)] in which the thiazolidine behaves as a bridging (N,S) donor group.

Discovery of 1,3-diphenyl-1H-pyrazole derivatives containing rhodanine-3-alkanoic acid groups as potential PTP1B inhibitors

Two series of 1,3-diphenyl-1H-pyrazole derivatives containing rhodanine-3-alkanoic acid groups were identified as competitive protein tyrosine phosphatase 1B (PTP1B) inhibitors. Among the compounds studied, IIIv was found to have the best in vitro inhibition activity against PTP1B (IC50 = 0.67 ¡À 0.09 muM) and the best selectivity (9-fold) between PTP1B and T-cell protein tyrosine phosphatase (TCPTP). Molecular docking studies demonstrated that compounds IIIm, IIIv and IVg could occupy simultaneously at both the catalytic site and the adjacent pTyr binding site. These results provide novel lead compounds for the design of inhibitors of PTP1B as well as other PTPs.
