    Discovery of a Clinical Stage Multi-Kinase Inhibitor Sodium (E)-2-{2-Methoxy-5-[(2′,4′,6′-trimethoxystyrylsulfonyl)methyl]phenylamino}acetate (ON 01910.Na): Synthesis, Structure–Activity Relationship, and Biological Activity
    摘要:
    Cyclin D proteins are elevated in many cancer cells, and targeted deletion of cyclin D1 gene in the mammary tissues protects mice from breast cancer, Accordingly, there is an increasing awareness of this novel nonenzymatic target for cancer therapeutics. We have developed novel, nonalkylating styrylbenzylsulfones that induce cell death in wide variety of cancer cells without affecting the proliferation and survival of normal cells. The development of derivatized styrylbenzylsulfones followed logically from a tumor cell cytotoxicity screen performed in our laboratory that did not have an a priori target profile. Modifications of some of the precursor molecules led to lead optimization with regard to tumor cell cytotoxicity. In this report we describe the synthesis and structure-activity relationships of novel, nonalkylating (E)-styrylbenzylsulfones and the development of the novel anticancer agent sodium (E)-2-{2-methoxy-5-[(2',4',6'-trimethoxystyrylsulfonyl)methyl]phenylamino}acetate (ON 01910.Na), which is in phase III trials for myelodysplastic syndromes (MDS) associated with aberrant expression of cyclin D proteins.

  • Basicity and Solvatochromism of Concave Pyridines with Extended π-Systems in Protic and Nonprotic Solvents

    4-positions of concave pyridines to give substituted concave pyridines 3, which possess absorption maxima above 300 nm in their UV spectra. Their protonation and their interaction with polar solvents have been studied. Firstly, with strong acids, protonation occurs, and relative basicities (logKass) have been determined. Substitution at the remote aryl ring influences the basicity of the pyridine, and Hammett
    芳炔取代基与凹吡啶的 4 位相连,得到取代的凹吡啶 3,其紫外光谱在 300 nm 以上具有最大吸收。已经研究了它们的质子化和它们与极性溶剂的相互作用。首先,使用强酸会发生质子化,并确定相对碱度 (logKass)。远程芳环上的取代会影响吡啶的碱性,哈米特图显示 logKass 与远程芳环的电子密度之间存在线性关系。其次,凹形吡啶 3 能够“感知”其吡啶氮原子和醇之间的氢键。当加入一定量的酒精时,观察到吸收最大值向更长波长的移动。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany,

    A stereoselective and efficient method for free radical addition of benzyl thiol to aryl acetylene in the presence of Et3B-hexane has been developed for the synthesis of (Z) and (E)-styryl benzyl sulfides where base catalyzed hydrothiolations have failed. The scope of this reaction was successfully extended for the synthesis of (E)-ON 01910·Na, a phase III clinical stage anti-cancer agent and its inactive

    Iridium‐catalyzed formal alkyne hydroboration with cage B−H of o ‐carborane has been achieved, leading to the controlled synthesis of a series of 3,6‐[trans ‐(AlkCH=CH)]2‐o ‐carboranes (Alk=alkyl), 3‐cis ‐(ArCH=CH)‐o ‐carboranes (Ar=aryl), and 3‐cis ‐(ArCH=CH)‐6‐trans ‐(AlkCH=CH)‐o ‐carboranes in high yields with excellent regio‐ and very good cis –trans selectivity.
