  Anthranilic acid based CCK1 receptor antagonists: preliminary investigation on their second “touch point”

  摘要：

  In this phase of structure-affinity relationship study of VL-0395, a new anthranilic acid based CCK1 selective antagonist, we propose a series Of Unnatural aminoacidic derivatives. The result of this work is the identification of a new CCK ligand, which possesses an affinity (IC50 = 35 nm) one order of magnitude greater than the lead and, as a general rule, it points out how the hypothesized receptorial pocket which accommodates the Phe residue allows much more structural modification than that interacting with the N-terminal group. Hence, the modification of the C-terminal pharmacophoric group of our lead VL-0395 can not only enhance the affinity of anthranific acid derivatives but can modulate the selectivity for one CCK receptor subtype or afford mixed antagonists.

  An approach to the parallel synthesis of hydantoin libraries by reaction of in situ generated 2,2,2-trifluoroethylcarbamates and α-amino esters was developed. To demonstrate utility of the method, a library of 1158 hydantoins designed according to the lead-likeness criteria (MW 200–350, cLogP 1–3) was prepared. The success rate of the method was analyzed as a function of physicochemical parameters

  开发了一种通过原位生成的2,2,2-三氟乙基氨基甲酸酯与α-氨基酯反应平行合成乙内酰脲文库的方法。为了证明该方法的实用性，准备了根据铅样标准（MW 200–350，cLogP 1-3）设计的1158个乙内酰脲文库。分析了该方法的成功率与产品理化参数的关系，发现该方法可以被认为是用于铅导向合成的工具。通过合理设计，使用开发的方法进行平行合成，计算机模拟和体外筛选相结合的方法，发现了一种含乙内酰脲的超微摩尔主要分子，可作为Aurora激酶A抑制剂。

  日期：——

  Asymmetric alkynylation of thiazolones and azlactones with alkynylbenziodoxolones as the electrophilic alkyne source catalyzed by thiourea phosphonium salt is described. By using thiazolones as nucleophiles, the desired alkyne functionalized thiazolones were obtained in 55–89% yields with 31–86% ee. Azlactones gave the desired products in comparable yields with lower enantioselectivities. Ring-opening
