The invention relates to a triazole and nicotine compound seed treating agent and a preparation method thereof. The effective component is a mixture of triazole bactericide and nicotine insecticide in a mass ratio of 1: (0.5-5), the triazole bactericide is tetraconazole, and the nicotine insecticide is thiamethoxam or clothianidin. The treating agent can be prepared into dispersable seed treating granule or suspending agent or seed coating agent. Compared with single preparations, the bactericidal effect of the composition tetraconazole is obviously improved, which proves that the effect of single pesticide is better due to the mixing of the triazole and nicotine, the prevention and control effect and scope are improved; the prevention and cure range of the compound is enlarged and the effect of killing both aphid and bacteria is realized, as compared with the single preparations in markets.

Colistin is a ?last resort? antibiotic for treatment of infections caused by some multidrug resistant Gram-negative bacterial pathogens. Resistance to colistin varies between bacterial species. Some Gram-negative bacteria such as Burkholderia spp. are intrinsically resistant to very high levels of colistin with minimal inhibitory concentrations (MIC) often above 0.5 mg/ml. We have previously shown DedA family proteins YqjA and YghB are conserved membrane transporters required for alkaline tolerance and resistance to several classes of dyes and antibiotics in Escherichia coli. Here, we show that a DedA family protein in Burkholderia thailandensis (DbcA; DedA of Burkholderia required for colistin resistance) is a membrane transporter required for resistance to colistin. Mutation of dbcA results in >100-fold greater sensitivity to colistin. Colistin resistance is often conferred via covalent modification of lipopolysaccharide (LPS) lipid A. Mass spectrometry of lipid A of DeltadbcA showed a sharp reduction of aminoarabinose in lipid A compared to wild type. Complementation of colistin sensitivity of B. thailandensis DeltadbcA was observed by expression of dbcA, E. coli yghB or E. coli yqjA. Many proton-dependent transporters possess charged amino acids in transmembrane domains that take part in the transport mechanism and are essential for function. Site directed mutagenesis of conserved and predicted membrane embedded charged amino acids suggest that DbcA functions as a proton-dependent transporter. Direct measurement of membrane potential shows that B. thailandensis DeltadbcA is partially depolarized suggesting that loss of protonmotive force can lead to alterations in LPS structure and severe colistin sensitivity in this species.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.1826-11-5, Name is 2-Phenylthiazole, molecular formula is C9H7NS. In a Article£¬once mentioned of 1826-11-5, name: 2-Phenylthiazole

The challenge of achieving selective and predictable functionalizations at C-H bonds with complex poly(hetero)aromatic substrates was addressed by two different approaches. Site-selectivity can be obtained by applying various reaction conditions that are (hetero)arene specific to substrates that contain indoles, pyridine N-oxide, and polyfluorinated benzenes. An experimental classification of electron-rich heteroarenes based on their reactivity toward palladium-catalyzed C-Hfunctionalization was established, the result of which correlated well with the order of reactivity predicted by the DFT-calculated concerted metalation-deprotonation (CMD) pathway. Model substrates containing two reactive heteroarenes were then reacted under general reaction conditions to demonstrate the applicability this reactivity chart in predicting the regioselectivity of the palladium-catalyzed direct arylation and benzylation reactions.

FLT3-ITD mutant has been observed in about 30% of AML patients and extensively studied as a drug discovery target. On the basis of our previous study that ibrutinib (9) exhibited selective and moderate inhibitory activity against FLT3-ITD positive AML cells, through a structure-guided drug design approach, we have discovered a new type II FLT3 kinase inhibitor, compound 14 (CHMFL-FLT3-213), which exhibited highly potent inhibitory effects against FLT3-ITD mutant and associated oncogenic mutations (including FLT3-D835Y/H/V, FLT3-ITD-D835Y/I/N/A/G/Del, and FLT3-ITD-F691L). In the cellular context 14 strongly affected FLT3-ITD mediated signaling pathways and induced apoptosis by arresting cell cycle into G0/G1 phase. In the in vivo studies 14 demonstrated an acceptable bioavailability (F = 19%) and significantly suppressed the tumor growth in MV4-11 cell inoculated xenograft model (15 mg kg-1 day-1, TGI = 97%) without exhibiting obvious toxicity. Compound 14 might be a potential drug candidate for FLT3-ITD positive AML.
