The chemical behavior of 4,9-dimethoxy-5-oxo-5H-furo[3,2-g]-chromene-6-carbonitrile (khellin-6-carbonitrile) (1) was examined towards a variety of nitrogen nucleophiles. Some novel Schiff bases 5-7 were prepared from reaction of carbonitrile 1 with some heterocyclic amines. Treatment of carbonitrile 1 with some hydrazine derivatives in boiling ethanol afforded pyrazole derivatives 8-13. Khellin-6-carbonitrile (1) reacted with hydrazine hydrate and phenylhydrazine in acetic acid to afford angular heteroannulated furo[3′,2′:6,7]-chromeno [4,3-c]pyrazol-4(1H)-one derivatives 14 and 15. Triazolo[1,5-a]pyrimidine 16 and pyrimido[1,2-a]benzimidazole 17 were synthesized through ring opening and recyclization reactions of compound 1 with 3-amino-1,2,4-triazole and 2-aminobenzimidazole, respectively. Reaction of compound 1 with guanidine and cyanoguanidine in ethanolic potassium hydroxide solution resulted in ring conversion giving the novel angular furo [3 ‘,2’ :6,7] chromeno [4,3-d]pyrimidin-5-ones 18 and 19. The antimicrobial activity of the prepared compounds appeared distinguish activity against the selected microorganisms.

The rice receptor-like cytoplasmic kinase 185 (OsRLCK185) interacts with the chitin receptor complex OsCERK1/CEBiP and positively regulates chitin-induced immune responses including MAP kinase activation, ROS production and defense gene expression. To elucidate the regulatory mechanisms of OsRLCK185-mediated immunity, we searched for interactors of OsRLCK185. OsDRE2a, rice homologs of the yeast Dre2 protein, were identified as novel interactors of OsRLCK185. OsDRE2a interacted with OsRLCK185 at plasma membrane. The conserved cysteine residues in CIAPIN1 domain of OsDRE2a were essential for tight interaction of OsRLCK185. OsDRE2a was phosphorylated by OsRLCK185. The expression of OsDRE2a and OsDRE2b was induced after chitin treatment. Reduction of OsDRE2a and OsDRE2b mRNA levels by RNA interference resulted in the decreased chitin-induced ROS production. Thus, it is likely that OsDRE2 regulates OsRLCK185-mediated immune responses.

Two Cu(II) coordination complexes, C1 and C2 of the formula [Cu(4)2(H2O)(2)], have been prepared by reaction between CuCl2 center dot 2H(2)O and 7-ethoxycarbonylmethyl-5-methyl-1,2,4[1,5-a]pyrimidine (L) in a 1:2 M:L molar ratio. The L molecule decomposes during the reaction process into 7-carboxy-5-methyl-[1,2,4]-triazolo[1,5-a]pyrimidine (4) through an intermediate, ethyl 2,2-dihydroxy-2-(5-methyl-[1,2,4]triazolo[1,5-a]pyrimidin-7-yl) acetate (5), which has been isolated and its crystal structure determined by X-ray diffraction. The X-ray analysis of the single crystals of [Cu(4)(2)(H2O)(2)] obtained from the slow evaporation of EtOH and MeOH, separately, revealed the formation of solvent induced polymorphs C1 and C2, respectively. The primary supramolecular synthon for C1 and C2 are six membered ring, and square shaped hydrogen bonded architecture, respectively. The self-assembly of such synthons resulted in a two dimensional hydrogen bonded sheet supported by O-H center dot center dot center dot O interactions. In addition, the antioxidant properties of the ligands and its complexes were evaluated in vitro using 1,1-diphenyl-2-picrylhydrazyl acid, 2,2′-azino-bis (3-ethylbenzothiazoline-6 sulfonic acid radical scavenging methods and ferric reducing antioxidant power.

INDETERMINATE DOMAIN (IDD) family proteins are plant-specific transcription factors. SomeArabidopsisIDD (AtIDD) proteins regulate the expression ofSCARECROW(SCR) by interacting with GRAS family transcription factors SHORT-ROOT (SHR) and SCR, which are involved in root tissue formation. Some AtIDD proteins regulate genes involved in the synthesis (GA3ox1) or signaling (SCL3) of gibberellic acid (GA) by interacting with DELLA proteins, a subfamily of the GRAS family. We analyzed the DNA binding properties and protein-protein interactions of select AtIDD proteins. We also investigated the transcriptional activity of the combination of AtIDD and GRAS proteins (AtIDD proteins combined with SHR and SCR or with REPRESSOR ofga1-3(RGA)) on the promoters ofSCR,SCL3, andGA3ox1by conducting a transient assay usingArabidopsisculture cells. Our results showed that theSCRpromoter could be activated by the IDD and RGA complexes and that theSCL3andGA3ox1promoters could be activated by the IDD, SHR, and SCR complexes, indicating the possibility that these complexes regulate and consequently coordinate the expression of genes involved in GA synthesis (GA3ox1), GA signaling (SCL3), and root formation (SCR).

The EFSA ‘Guidance on tiered risk assessment for edge-of-field surface waters’ underscores the importance of in silico models to support the pesticide risk assessment. The aim of this work was to use in silico models starting from an available, structured and harmonized pesticide dataset that was developed for different purposes, in order to stimulate the use of QSAR models for risk assessment. The present work focuses on the development of a set of in silico models, developed to predict the aquatic toxicity of heterogeneous pesticides with incomplete/unknown toxic behavior in the water compartment. The generated models have good fitting performances (R-2 : 0.75-0.99), they are internally robust (Q(2) loo: 0.66-0.98) and can handle up to 30% of perturbation of the training set (Q(2) Imo: 0.64-0.98). The absence of chance correlation was guaranteed by low values of R-2 calculated on scrambled responses (R-2 Y-scr: 0.11-0.38). Different statistical parameters were used to quantify the external predictivity of the models (CCCext: 0.73-0.91, Q(2) ext-Fn: 0.53-0.96). The results indicate that all the best models are predictive when applied to chemicals not involved in the models development. In addition, all models have similar accuracy both in fitting and in prediction and this represents a good degree of generalization. These models may be useful to support the risk assessment procedure when experimental data for key species are missing or to create prioritization lists for the general a priori assessment of the potential toxicity of existing and new pesticides which fall in the applicability domain.

Based on the previous studies that revealed the valuable role of pyrazole scaffold in cancer management and VEGFR-2 inhibition, a new set of pyrazole conjugated with pyrazoline, triazolopyrimidine and pyrazolone moieties were synthesized and investigated for their anticancer efficiency against human breast cancer MCF-7. The anticancer screening revealed the significant sensitivity of breast carcinoma towards compounds 4b, 5c, 6c, 7b, 7c and 12c with IC50 values ranging from 16.50 – 26.73 mu M in comparison with tamoxifen (IC50 = 23.31 mu M). Moreover, the new analogues were further examined for their VEGFR-2 inhibitory activity, among the tested derivatives 5c, 6c, 7b, 7c and 12c displayed prominent inhibitory efficiency versus VEGFR-2 kinase with % inhibition ranging from 70 to 79%. Compounds 6c, 7c and 12c revealed inhibitory efficiency in nanomolar level with IC50 (913.51, 225.17 and 828.23 nM, respectively) comparing to sorafenib (IC50 = 186.54 nM). Flow cytometric analysis revealed that the promising compound 12c prompted pre-G1 apoptosis and cell growth cessation at G2/M phase and stimulated apoptosis via activation of caspase-3. Moreover, molecular docking study of the promising derivatives was performed to highlight their binding modes and interactions with the amino acid residues of VEGFR-2 enzyme.

A key step in the risk assessment process of a substance is the assessment of its genotoxic potential. Irrespective of the industry involved, current approaches rely on combinations of two or three in vitro tests and while highly sensitive, their specificity is thought to be limited. A refined in vitro genotoxicity testing strategy with improved predictive capacity would be beneficial and 3R friendly as it helps to avoid unnecessary in vivo follow-up testing. Here, we describe a proof of concept study evaluating a balanced set of compounds that have in vivo negative or positive outcomes, but variable in vitro data, to determine if we could differentiate between direct and indirect acting genotoxicants. Compounds were examined in TK6 cells using an approach in which the same sample was used to evaluate both early genomic markers (Affymetrix analysis 4 hr post treatment), and the genotoxic outcome (micronuclei [MN] after 24 hr). The resulting genomic data was then analyzed using the TGx-DDI biomarker, Connectivity mapping and whole genome clustering. Chemicals were also tested in the ToxTracker assay, which uses six different biomarker genes. None of the methods correctly differentiated all direct from indirect acting genotoxicants when used alone, however, the ToxTracker assay, TGx-DDI biomarker and whole genome approaches provided high predictive capacity when used in combination with the MN assay (1/18, 2/18, 1/18 missed calls). Ultimately, a fit for purpose combination will depend on the specific tools available to the end user, as well as considerations of the unique benefits of the individual assays.

Heterotrimeric G-protein a and beta-subunits regulate H2O2-mediated aerenchyma formation. The rice G-protein gamma-subunit, dense and erect panicle 1 (DEP1), is known to interact with the a-subunit and regulate nitrogen utilization and yield. However, it is unclear whether DEP1 regulates cell death for aerenchyma formation in rice roots. Using wild-type WYJ8 and its transgenic line WYJ8(DEPJ), we confirmed that DEP1 is involved in H2O2-mediated aerenchyma formation. The rates of aerenchyma formation varied in different parts of the roots in both varieties, with the highest rate in the 4-7 cm segments, reaching a plateau in the 7-8 cm segments. Compared with WYJ8, the aerenchyma area and H2O2 content in WYJ8(DEP1) were increased by 55.98% and 53.37%, respectively; however, the responses of aerenchyma formation to exogenous H2O2 were basically the same in the two varieties. Diphenylene iodonium (DPI) treatment had no effect on H2O2 production and elimination processes in WYJ8, but significantly reduced the activity of the key enzyme that catalyzes H2O2 biosynthesis in WYJ8(DEP1). Importantly, exogenous H2O2 treatment did not offset the effect of the decrease in endogenous H2O2 level caused by DPI on aerenchyma formation. These results indicated that DEP1 enhanced H2O2 biosynthesis and promoted the cell death of the root cortex, thus contributing to aerenchyma development in WYJ8(DEP1).
