  Design, synthesis and 3D-QSAR studies of novel 1,4-dihydropyridines as TGFβ/Smad inhibitors

  摘要：

  Targeting TGF beta/Smad signaling is an attractive strategy for several therapeutic applications given its role as a key player in many pathologies, including cancer, autoimmune diseases and fibrosis. The class of b-annelated 1,4-dihydropyridines (DHPs) represents promising novel pharmacological tools as they interfere with this pathway in a novel fashion, i.e. through induction of TGF beta receptor type II degradation. In the present work, >40 rationally designed, novel DHPs were synthesized and evaluated for TGF beta inhibition, substantially expanding the current understanding of the SAR profile. Key findings include that the 2-position tolerates a wide variety of polar functionalities, suggesting that this region could possibly be solvent-exposed within the (thus far) unknown cellular target. A structural explanation for pathway selectivity is provided based on a diverse series of 4"-substituted DHPs, including molecular electrostatic potential (MEP) calculations. Moreover, the absolute configuration for the chiral 4-position was determined by X-ray crystal analysis and revealed that the bioactive (+)-enantiomers are (R)configured. Another key objective was to establish a 3D-QSAR model which turned out to be robust (r(2) = 0.93) with a good predictive power (r(pred)(2) = 0.69). This data further reinforces the hypothesis that this type of DHPs exerts its novel TGF beta inhibitory mode of action through binding a distinct target and that unspecific activities that would derive from intrinsic properties of the ligands (e.g., lipophilicity) play a negligible role. Therefore, the present study provides a solid basis for further ligand-based design of additional analogs or DHP scaffold-derived compounds for hit-to-lead optimization, required for more comprehensive pharmacological studies in vivo.

  固定在多壁碳纳米管上的镍 (II) Schiff 碱配合物用于 Hantzsch 四组分缩合的合成、表征和多相催化应用

  摘要：

  摘要 合成了一种固定在多壁碳纳米管 (MWCNTs) 表面的镍 (II) Schiff 碱配合物作为一种高效的多相催化剂，并通过 IR、X 射线衍射图、扫描电子显微镜、能量色散 X 射线光谱进行表征。 、电感耦合等离子体、元素分析和热重分析。然后，在上述合成催化剂的存在下，在无溶剂条件下，通过芳香醛、1,3-二酮、乙酰乙酸乙酯和乙酸铵的 Hantzsch 一锅缩合反应，开发了一种简便且环境友好的方法合成聚氢喹啉衍生物。该方案具有催化剂稳定性、易得性、可回收性和环保性，实验和后处理程序简单等优点，并且产量也很高。考虑到模型反应的无溶剂条件以及温度、时间和产率，这里报道的纳米催化剂是迄今为止报道的用于合成聚氢喹啉的最佳催化剂之一。

  A novel, green and reusable nano ionic liquid and catalyst, namely 1-methylimidazolium trinitromethanide [HMIM]C(NO2)3}, was designed and fully characterized by 1H NMR, 13C NMR, IR, mass, X-ray diffraction patterns (XRD) and Transmission electron microscopy (TEM) analysis. The catalytic application of the presented catalyst was successfully tested on the Hantzsch four-component reaction of various aromatic aldehydes, 1,3-dione, β-ketoester and ammonium acetate at room temperature under solvent-free and mild conditions to give the polyhydroquinoline derivatives in good to excellent yields.

  A convenient and environmentally friendly procedure for the synthesis of polyhydroquinolines via a one-pot, four component condensation of different aromatic aldehydes with dimedone, ethyl acetoacetate and ammonium acetate has been developed. Upon heating at 100 °C, the desired products were produced in good to excellent yields with short reaction times under catalyst- and solvent-free conditions.
