  Amide-modified prenylcysteine based Icmt inhibitors: Structure–activity relationships, kinetic analysis and cellular characterization

  摘要：

  Human protein isoprenylcysteine carboxyl methyltransferase (hIcmt) is the enzyme responsible for the alpha-carboxyl methylation of the C-terminal isoprenylated cysteine of CaaX proteins, including Ras proteins. This specific posttranslational methylation event has been shown to be important for cellular transformation by oncogenic Ras isoforms. This finding led to interest in hIcmt inhibitors as potential anti-cancer agents. Previous analog studies based on N-acetyl-S-farnesylcysteine identified two prenylcysteine-based low micromolar inhibitors (1a and 1b) of hIcmt, each bearing a phenoxyphenyl amide modification. In this study, a focused library of analogs of 1a and 1b was synthesized and screened versus hIcmt, delineating structural features important for inhibition. Kinetic characterization of the most potent analogs 1a and 1b established that both inhibitors exhibited mixed-mode inhibition and that the competitive component predominated. Using the Cheng-Prusoff method, the K-i values were determined from the IC50 values. Analog 1a has a K-IC of 1.4 +/- 0.2 mu M and a K-IU of 4.8 +/- 0.5 mu M while 1b has a K-IC of 0.5 +/- 0.07 mu M and a K-IU of 1.9 +/- 0.2 mu M. Cellular evaluation of 1b revealed that it alters the subcellular localization of GFP-KRas, and also inhibits both Ras activation and Erk phosphorylation in Jurkat cells. (C) 2011 Elsevier Ltd.

• Structure-Based Design, Synthesis, and Biological Evaluation of New Triazolo[1,5-<i>a</i>]Pyrimidine Derivatives as Highly Potent and Orally Active ABCB1 Modulators

  ABCB1 is a promising therapeutic target for overcoming multidrug resistance (MDR). In this work, we reported the structure-based design of triazolo[1,5-a]pyrimidines as new ABCB1 modulators, of which WS-691 significantly increased sensitization of ABCB1-overexpressed SW620/Ad300 cells to paclitaxel (PTX) (IC50 = 22.02 nM). Mechanistic studies indicated that WS-691 significantly increased the intracellular

  ABCB1是克服多药耐药性（MDR）的有希望的治疗靶标。在这项工作中，我们报道了作为新的ABCB1调节剂的三唑并[1,5- a ]嘧啶的结构设计，其中WS-691显着提高了ABCB1过表达的SW620 / Ad300细胞对紫杉醇（PTX）的敏感性（IC 50 = 22.02 nM）。机理研究表明，WS-691通过抑制ABCB1的外排功能，显着增加PTX和[ 3 H] -PTX的细胞内浓度，同时降低SW620 / Ad300细胞中[ 3 H] -PTX的外排。细胞热位移分析表明，WS-691可通过直接结合ABCB1来稳定ABCB1。WS-691可以刺激ABCB1 ATPase的活性，但对CYP3A4几乎没有抑制活性。重要的是，WS-691在体内没有观察到毒性的情况下提高了SW620 / Ad300细胞对PTX的敏感性。总体而言，WS-691是一种高效且口服的ABCB1调节剂，能够克服MDR。三唑并[1，5-

  A serendipitous discovery of a novel one-pot synthesis of 4,6-disubstituted 5-azaindoles is reported herein. In the presence of Hunig's base, various N-substituted pyrrole-2-carboxaldehydes have been efficiently transformed into their corresponding 4,6-disubstituted 5-azaindoles through an imine mediated cascade condensation-heteroannulation. The synthetic value of the methodology is established by
