  二和三有机锡（IV）与硫代氨基脲衍生物的合成，抗菌活性和分子对接

  摘要：

  已经合成了六种有机锡（IV）配合物，具有两个分别来自2,3-丁二酮和硫代氨基脲的配体，并通过多种光谱技术进行了全面表征，包括119 Sn NMR和单晶X射线衍射。配体二乙酰基-2-（硫代半碳carb）-3-（3-羟基-2-萘hydr）L 1 H 2与SnR 2 Cl 2（R = Me，Bu，Ph）的反应导致获得络合物1 – 3具有通式[SnR 2 L 1 ]（R = Me 1，R = Bu 2，R = Ph 3），其中配体被双去质子化并且表现为N2 SO供体，而从二乙酰基-2-硫代半碳胺，HATs与相同的有机锡前体的反应中，可以分离出任何络合物。与此相对，SNR帽子反应3氯诱导配体环化以形成1,2,4-三嗪-3-硫酮，其结合到所述金属如单或双齿方式形式的化合物的单阴离子供体4 - 6与公式[SnR 3 L 2 ]（R = Me 4，R = Bu 5，R = Ph 6）。测试了配体和六种复合

  Environmental controls of NDVI and sheep production in the Tierra del Fuego steppe of Argentina

  摘要：

  Abstract. We analysed vegetation dynamics in Tierra del Fuego steppes using Normalized Difference Vegetation Index (NDVI) data provided by advanced very high‐resolution radiometer (AVHRR) on board the National Oceanic and Atmospheric Administration (NOAA) polar satellite. Our objective, at a regional scale, was to analyse the spatial variability of NDVI dynamics in relation to parent material and geographic location, representing the fertility and climate gradients respectively; at a local scale, it was to analyse the inter‐annual variability associated with climate and its relation with sheep production indices. The general pattern of NDVI dynamics was analysed with Principal Component Analysis. We found that the geographic location was more important than landscape type in explaining NDVI dynamics despite the fact that the variation in landscape type reflects a fertility gradient strongly associated with floristic composition and secondary productivity.Discriminant Analysis was performed to identify the variables that better distinguish geographic units. The Northern region (with the lowest precipitation and the highest temperatures) had lower NDVI values over the year. In the Central region, NDVI reached the highest value of the season, surpassing both other regions. The Southern region (the coldest and moistest) had its growth pattern displaced towards the summer. For the Central region we analysed 10 years of monthly NDVI data with PCA. We found that precipitation from August to December and winter temperature are the most important determinants of overall NDVI values. Lamb production was correlated with spring and early summer NDVI values. Sheep mortality is affected by low NDVI values in late summer and high annual amplitude. Satellite information allowed us to characterize the vegetation dynamics of three ecological areas across the Fuegian steppe.

• N*-N*-S* Tridentate ligand system as potential antitumor agents

  Compounds containing an N*-N*-S* tridentate ligand were synthesized and tested for antitumor activity against P-388 lymphocytic leukemia in mice. Of these, only 2,2'-bipyridyl-6-carbothioamide (1a) showed antitumor activity at relatively high dosage levels. Compound 1a was also evaluated against L-1210 and S180 cells in culture and found to have significant activity.
