  Design and characterization of mechanism-based inhibitors for the tyrosine aminomutase SgTAM

  摘要：

  The synthesis and evaluation of two classes of inhibitors for SgTAM, a 4-methylideneimidazole-5-one (MIO) containing tyrosine aminomutase, are described. A mechanism-based strategy was used to design analogs that mimic the substrate or product of the reaction and form covalent interactions with the enzyme through the MIO prosthetic group. The analogs were characterized by measuring inhibition constants and X-ray crystallographic structural analysis of the co-complexes bound to the aminomutase, SgTAM.

  A novel and simple procedure was developed for the regioselective synthesis of α-bromo (di)ketones from electron-rich epoxides via visible light photoredox catalysis. Through optimization of solvent and light source, the reaction can be rapidly achieved under mild conditions. Moreover, the possible reaction mechanism was proposed and further supported by control experiments.

  日期：2010.2.22

  Divergent reactivity: Various ethynylaziridines behave as strained propargyl amines and can be directly converted into unprotected α‐amino allenes by a highly diastereoselective SN2′ hydride delivery (see scheme). Additional reaction routes involve chemo‐ and regioselective transformation into either bicyclic aziridine/enol ethers or highly strained azirine alkynes.

  In order to improve the potency and duration of biological actions of diltiazem, a number of 1, 5-benzothiazepine derivatives having the substituents at the 8 position were prepared and evaluated for their antihypertensive activity in spontaneously hypertensive rats. The introduction of methyl, ethyl, isopropyl, benzyl, methoxy, ethoxy, phenoxy, and methylthio groups increased the antihypertensive activity and prolonged duration of action, whereas cyclohexyl, cyclopentoxy, tolyloxy, p-methoxyphenoxy and phenylthio derivatives were less active than diltiazem. Among them, the 8-benzyl and phenoxy derivatives showed the most potent and long-lasting antihypertensive action.
