  A Simple and Efficient Method for Synthesis of Benzothiazepine Derivatives

  摘要：

  A series of 1,5-benzothiazepines were synthesized using disulfides and alpha,beta-unsaturated carbonyl or nitrite compounds as reaction substrates. After reductive cleavage of the S-S bond of disulfides, the resulting thiols were reacted with alpha,beta-unsaturated carbonyl or nitrite compounds to generated seven-membered heterocyclic compounds. In the presence of ammonium thioglycolate, the Michael reaction occurred between disulfides (1) and 4-methyl-3-penten-2-one to give 2,2,4-trymethyl-3H-1,5-benzothiazepine derivatives in good yields. When ethyl acrylate or acrylonitrile was used as the Michael acceptor, 90-99% of (2-amino-phenylsulfanyl)propionitriles (3) and/or 92-99% of (2-amino-phenylsulfanyl)propionic acid ethyl esters (4) were produced. Subsequently, the 1,5-benzothiazepine compounds 5 and 6 were obtained due to the cyclization reaction.

  and ammonium thiocyanate (1.0 equiv) in DMSO:H2O (9:1) at 70 °C gave the corresponding 2-aminobenzothiazoles in excellent isolated yields (75–97%; ave. yield for all substrates = 90%). The reaction worked well for 2(4)-mono-, 2,4-di-, or 3,4,5-tri-substituted anilines, and a wide range of both electron donating groups (MeO, HO, CF3O, Me) and electron withdrawing groups (NO2, CN, CO2Et, CO2H, Cl, F)

  unrecognized binding site on the aldose reductase (AR) enzyme with strong affinity for benzothiazoles was pursued for the design of novel, potent aldose reductase inhibitors (ARIs). The first application of this hypothesis led to a novel series of 3,4-dihydro-4-oxo-3-(benzothiazolylmethyl)-1-phthalazineacetic+ + + acids. The parent of this series (207) was a potent inhibitor of AR from human placenta (IC50

  为了设计新型有效的醛糖还原酶抑制剂（ARI），人们寻求了一个新的工作假设，即在醛糖还原酶（AR）酶上具有迄今无法识别的结合位点，该结合位点对苯并噻唑具有很强的亲和力。该假设的首次应用产生了一系列新的3,4-二氢-4-氧代-3-（苯并噻唑基甲基）-1-酞嗪乙酸+ + +酸。该系列的母体（207）是一种有效的人胎盘AR抑制剂（IC50 = 1.9 x 10（-8）M），在糖尿病合并症的急性试验中，口服有效预防山楂醇在大鼠坐骨神经中的蓄积（ ED50 ＝ 18.5mg / kg）。通过药物化学原理（包括与其他药物系列的比喻）优化该线索，导致产生更有效的207同类药物，并最终设计出3，4-二氢-4-氧代-3-[[[5-（三氟甲基）-2-苯并噻唑基]甲基] -1-酞嗪乙酸（216，CP-73,850，zopolrestat）。在体外和体内，Zopolrestat被发现比207更有效。在急性试验中，其针对AR和ED50的IC50分别为3
