重要的新发现

Among those hydrogenbonding residues, Tyr119, His227, Asn392 and Leu451 could form hydrogen bond with the benzofuran inhibitots and Tyrl07, Asn175, Thr211 and Asp412 were newly discovered hydrogen-bonding residues, which were highly conserved residues across the NMT family and would play an important role in the design of NMT inhibitots with novel chemical scaffold.

CaNMT活性位点发现有两个氧键作用区域，其中Tyrll9，His227，Asn392和Leu451是与已有抑制剂的氢键结合位点，Tyr107，Asn175，Thr211和Asp412是新发现的氢键结合位点，而且在NMT家族中高度稳定，它们对设计新结构类型的CaNMT抑制剂具有重要作用。

The great potentials for exploration of litho-stratigraphic reservoirs do not appear until new methods and technologies have been applied and in-depth understandings have been gained. In recent two or three years, big discoveries have been made in Jilin oilfield, in which 80 percent of reserves are found in some areas of thin sand-shale interbedding of its delta front. There still exist petroleum potentials amounting to 6×10^8 t for exploration in this area, especially in southern Songliao basin where the litho-stratigraphic traps will be more important domains and deserve extra attention. Hence, geologically speaking, this study on the hydrocarbon accumulation of litho-stratigraphic reservoirs in Songliao basin is of vital significance to exploration of the southern Songliao basin.

但通过新方法、新技术的应用和地质认识的不断深入，岩性－地层油气藏展现出了较大的勘探潜力，吉林油田近2-3年来的大发现和新增储量的80％是在有一定面积的三角洲前缘薄互层中获得的，在这个领域中仍有6×10^8t的石油资源有待勘探，特别是松辽盆地南部地层－岩性圈闭是未来油气勘探的重要领域，具有进一步解剖研究和勘探价值，因此，对松辽盆地岩性－地层油气藏成藏规律进行研究，对于松辽盆地南部勘探有着十分重要的意义。

First,we have discovered stone artefacts in caves, which have similar features to that were broadly scattered in laterite terraces in Bose basin(0.8 Ma B.P),next study on deposits and fauna will be hopefully contributed to document paleoenvironmental background of early human;Second,early human fossils,Gigantopithecus and mammalian fossils unearthed in Mohui cave provide new evidence of early human origin; Third,after our scientific excavation in Fengshudao site in Bose basin, we have found five pieces of bi-face LCT with 10 tektites and nearly 100 stone artefacts form original laterite deposit.This important discovery is very answerable to international question about stratigraphic suspect of LCT; Fourth, abounding mammallian fossils with human fossils and remains from early Pleistocene to Holocene have been uncovered after systematically excavation in marginal cave of Bose basin.These discoveries are significant to the study on human evolution and establishment of sequence of Quarternary biological-stratigraphic in southern China.

These compounds are of substantial interest both inviewpoints of theory and practical applications, mainlyunder the stimulus to achieve synthetic models either foractive sites of iron-sulfur proteins or for transitionmetal catalysts. This thesis describes the synthesis, structures andconformations of 51 new iron-sulfur cluster complexes,which have been characterized by elemental analysis andstandard spectroscopic methods. In addition, single-crystalX-ray diffraction analyses were performed for 4 representa-tive new compounds. Reactivities of μ-〓 with mono- and di- Grig-nard reagents derived intermediates toward various organicelectrophilic substrates were studied, along with complexa-tion of arynyl-containing iron-sulfur clusters by 〓Thus, several bridged, non-bridged, monomeric, dimeric,homonuclear, heteronuclear iron-sullfur and iron-sulfur co-balt-carbon cluster complexes were synthesized. A novelreaction and convenient route for the synthesis in highyield of tetranuclear iron complexes 〓 containing atetracoordinated sulfur atom was discovered, whereas aplausible mechanism based on experimental results was propo-sed for the formation of the new cluster type.

Several anti-tumor cell lines and carbonic anhydrase Ⅱ model were established. More than 10000 compounds and extracts from plants were screened using these models and about 10 compounds showed strong inhibitory activities. Two species of plants Inula helianthus-aquatica and Saussurea deltoidea were chosen to investigate chemical and bioactivity constituents based on the results of screening of extracts and fractions. 58 compounds were isolated and identified from these two plants, 6 compounds were found to be new and 14 compounds showed anti-tumor activities. We also studied the anti-tumor mechanism of the compound bigelovin isolated from Inula helianthus-aquatica. Bigelovin was found with apoptotic activity against cell line U266 by lowering the amount of important transcription factor E2F-1 which inhibits the cell cycle at G0/G1 stage. Docking study on 7 natural new phenolic inhibitors of CA Ⅱ and 3D-QSAR study on 61 sulfonamide inhibitors of CA Ⅱwere also investigated. The calculated results were in good correlation with experimental results.
