制备了一系列Nα-(芳基磺酰基)-L-精氨酸酯,并测试了它们作为凝血酶凝血活性的抑制剂。Nα-丹磺酰基-L-精氨酸甲酯对Nα-(芳基磺酰基)-L-精氨酸甲酯的抑制作用最大。最有效的抑制剂是Nα-丹磺酰基-L-精氨酸的正丙酯和正丁酯,其I50为2 X 10(-6)M。链长为四个碳的不饱和直链醇的酯也具有与正丁酯一样的抑制作用。抑制剂被凝血酶和胰蛋白酶水解的速度比Nα-甲苯磺酰基-L-精氨酸甲酯慢。

used to treat type-II diabetes mellitus, but also linked to several harmful effects. Therefore, it is essential to explore new and nontoxic antidiabetic agents with additional antioxidant properties. In this connection, a series of new N-sulfonohydrazide substituted indazoles 1-19 were synthesized by multistep reaction scheme and assessed for in vitro α-amylase inhibitory and radical (DPPH and ABTS)
Two fluorescentsubstrates for protein tyrosine phosphatase (PTPase) reaction were prepared by conjugation of commercially available O-phosphotyrosine and dansyl chlorides. They were hydrolyzed by CD45 tyrosine phosphatase, and proved to be useful for PTPase assay.
Furo- and thienopyrimidine derivatives, which are useful as TIE-2 and/or VEGFR-2 inhibitors are described herein. The described invention also includes methods of making such furo- and thienopyrimidine derivatives as well as methods of using the same in the treatment of hyperproliferative diseases.

This invention concerns the remote detection of threat clouds and evaluation of their components. Also included is the remote detection and evaluation of contamination on surfaces or in air streams. To enable this detection, fluorophores that are attached to POSS are used with two-photon LIF imaging that provides enhanced background-free imaging even in the presence of scattering particles such as dust, sand and water droplets.
