四唑

Methods Compounds were isolated and purified by various column chromatographic techniques and their structures were elucidated on the basis of spectral analysis (IR, ESIMS, 1HNMR, 13CNMR). The inhibitory activity against the proliferation of HL60, REH and Raji cell lines was determined by using MTT assay.

The adipose derived stem cells of inbreds train of rat wereinduced to differentiate into schwann-like cells and the cells were injectedinto the acellular nerve allograff.The proliferation or adhersion of these cells on the graft were observed by inverted microscope or ScanningElectronic Microscope. Activity of cells were detected using MTT. 10mmnerve gap of inbreds train of rats in two group were bridged by tissue-engineered peripheral nerve or autogenous nerve, the effect wereappraised by naked eye, recovery rate of sciatic function index,nerve-electrophysiological, histology, Transmission ElectronMicroscopy and quantitative analysis of recovery rate of myelinated fiberpopulations,diameter of myelinated fiber and thickness of myelin sheat.

The gaseous tetrazole compounds exist mainly in the 2H-form whereas the 1H-tetrazole derivatives dominate in the condensed phase.

气相中四唑主要以2H-式存在而在极性溶剂中则相反。

They have tested the sensitivity of a series of tetrazole complexes and obtained the relative magnitude of sensitivity of a number of 5- substituted tetrazole derivatives.

但文献调研表明，整体而言，前人在该领域的实验和理论工作数量较少(多数仅为氨基和烷基四唑衍生物)、涉及面较窄、精确性较差，更缺乏系统性。

Comparisons show that there is no correlation between the experimental sensitivity of tetrazole compounds and various previously proposed theoretical static criteria, such as the bond length and bond order of relevant bonds, net atomic charges and electronegativity and the content of 2H-teterazole isomers in both gaseous and condensed states.

把四唑衍生物的实验感度与前人曾提出过的各种感度理论判据—一些静态结构性质(如相关键的键长、键级、原子电荷和电负性等)以及平衡体系中2H-异构体的含量—进行比较，均未找到它们之间的规律性联系。
