  Design, synthesis and molecular modelling of novel 4-thiazolidinones of potential activity against Gram positive bacteria

  摘要：

  A series of novel 4-thiazolidinones (2-21) incorporating 2-(2,4,5-trichlorophenoxy)propanamide was synthesised. Reaction of 2-(2,4,5-trichlorophenoxy)propanohydrazide (1) with the corresponding carbonyl compounds afforded 2-(2,4,5-trichlorophenoxy)propanehydrazide hydrazones (2-11) which upon reaction with thioglycolic acid revealed 4-thiazolidinone derivatives (12-21). Structure elucidation of the synthesised compounds was done based on analytical and spectral data. The newly synthesised compounds were evaluated for their antimicrobial activity. Compounds 13 and 17 showed the equipotent activity with MIC value 6.25 mu g ml(-1) compared with chloramphenicol as reference drug. Docking studies of the promising compounds was done on MurB using Dock6.4 docking program to study their observed activity.

  A versatile and sustainable approach to one of the most commonly employed families of herbicides has been developed, which is based on a biocatalytic reductive dehalogenation followed by simple chemical manipulations. A range of commercially relevant target molecules have been obtained in good yield and moderate to excellent enantioselectivity (to either enantiomer), without chromatographic purifications

  对于最常用的除草剂家族之一，已经开发出一种通用且可持续的方法，该方法基于生物催化还原脱卤，然后进行简单的化学操作。一系列商业相关的目标分子已经以良好的收率和中等至极好的对映选择性（对任一对映异构体）获得，无需色谱纯化和使用粗酶制剂。

  Disclosed is an electronic ID database and detection method for pesticide compounds in edible agro-products based on GC-Q-Orbitrap. The electronic ID database includes a collection of various pesticide compounds electronic ID information and is sorted according to retention time in the electronic ID. The electronic ID contains pesticide compounds information, retention time, mass spectrum, fragment ions information and intelligent matching value. The detection method includes sample pretreatment procedures, setting GC-Q-Orbitrap operating conditions and screening procedures for pesticide residues in samples, wherein setting GC-Q-Orbitrap operating conditions includes setting suitable chromatography and mass spectrometry conditions. In pesticide residue screening procedures, firstly, the retention time is used to find out pesticide compounds in electronic ID database. If there is a match, the corresponding electronic ID information is extracted. Then the intelligent matching value is compared, if it is less than threshold value, the result is recorded and displayed, and the screening is completed.
