  Acyl derivatives of p-aminosulfonamides and dapsone as new inhibitors of the arginine methyltransferase hPRMT1

  摘要：

  Arginine methylation is an epigenetic modification that receives increasing interest as it plays an important role in several diseases. This is especially true for hormone-dependent cancer, seeing that histone methylation by arginine methyltransferase I (PRMT1) is involved in the activation of sexual hormone receptors. Therefore, PRMT inhibitors are potential drugs and interesting tools for cell biology. A dapsone derivative called allantodapsone previously identified by our group served as a lead structure for inhibitor synthesis. Acylated derivatives of p-aminobenzenesulfonamides and the antilepra drug dapsone were identified as new inhibitors of PRMT1 by in vitro testing. The bis-chloroacetyl amide of dapsone selectively inhibited human PRMT1 in the low micromolar region and was selective for PRMT1 as compared to the arginine methyltransferase CARM1 and the lysine methyltransferase Set7/9. It showed anticancer activity on MCF7a and LNCaP cells and blocked androgen dependent transcription specifically in a reporter gene system. Likewise, a transcriptional block was also demonstrated in LNCaP cells using quantitative RT-PCR on the mRNA of androgen dependent genes. (C) 2011 Elsevier Ltd. All rights reserved.

  摘要：

  The reactions of aryl benzenesulfonates (YC6H4SO2OC6H4Z) with benzylamines (XC6H4CH2NH2) in acetonitrile at 65.0 degrees C have been studied. The reactions proceed competitively by S-O (kS-O) and C-O (kC-O) bond scission, but the former provides the major reaction pathway. On the basis of analyses of the Hammett and Brönsted coefficients together with the cross-interaction constants rho(XY), rho(YZ)

  研究了芳基苯磺酸盐（YC6H4SO2OC6H4Z）与苄胺（XC6H4CH2NH2）在乙腈中于65.0摄氏度下的反应。反应通过SO（kS-O）和CO（kC-O）键分裂而竞争地进行，但前者提供了主要的反应途径。在分析Hammett和Brönsted系数以及交叉相互作用常数rho（XY），rho（YZ）和rho（XZ）的基础上，提出了通过限速形成SO键裂解的逐步机理三角-双锥体五元（TBP-5C）中间体，而CO键断裂则是通过限速从Meisenheimer型络合物中排出磺酸根阴离子（YC6H4SO3-）来进行的。

The construction of one C−C bond and two C−N bonds via cleavage of one N−S, one C−S, and one C−X (X=F, Cl, Br, O) bond is achieved under transition‐metal‐free conditions in one step. This transformation generates 1 equiv. of sulfur dioxide and 1 equiv. of hydrogen halide as the byproducts. The broad substrate
