Synthesis of α-(p-Toluenesulfonamido)-Phosphonic Acid Derivatives and Phosphonopeptides and Their Biologic Activity PH.D.

为寻找高效选择性除草剂，我们设计、合成了新型含磺酰基α-氨基膦酸和膦肽衍生物共96个，并研究了有关的化学反应。

We screened a set of Lewis base organocatalysts derived from chiral pipecolinic acid and tert-butanesulfinamide for the reduction of-N-Cbz-1- phenylpropenamine, including newly designed ones and some of those previously developed in our lab. However, only moderate stereoselectivities, albeit high yields were obtained.

在本课题组前期研究的基础上，我们筛选并设计了一系列以手性哌啶酸和叔丁基亚磺酰胺为母体的有机小分子路易斯碱催化剂，它们能催化三氯氢硅对-N-苄氧羰基-1-苯基丙烯胺的不对称还原，获得很高的收率和中等的对映选择性，并且具有很好的底物普适性。

Taurocholic Acid is a kind of tauro-conjugated bile acid which exists in many kinds of animals' bile.

牛磺胆酸(Taurocholate acid， TCA)是存在于多种动物胆汁中的一种结合型胆汁酸。

PBMC treated with inhibitor N-tosyl phenylalanine chlormethyl ketone, Astragalus can increase the activity of NF-κ B and the concentration of IL-8 in patients with PNS. it also increases the the activity of NF-κ B in normal children , but can ' t affected the concentration of IL-8 in normal children. ConclusionIn patients with PNS , the activity of NF-κ B was up-regulated and the level of IL-8 was significantly elevated.

结果肾病患儿 NF-κ B 活性及 IL-8含量增高，2者呈正相关； IL-1β刺激后，黄芪降低肾病患儿 NF-κ B 活性及 IL-8含量、降低正常儿童 NF-κ B 活性而不影响 IL-8含量；用对甲苯磺酰-L-苯丙氨酸氯甲基甲酮抑制后，黄芪可提高肾病患儿 NF-κ B 活性及 IL-8含量、提高正常儿童 NF-κ B 活性；而不影响 IL-8含量。
