  • CYCLOSPORINE ANALOGUE MIXTURES AND THEIR USE AS IMMUNOMODULATING AGENTS
    申请人:Aurinia Pharmaceuticals Inc.
    公开号:US20160075741A1
    公开(公告)日:2016-03-17
    The invention is directed to isomeric mixtures of cyclosporine analogues that are structurally similar to cyclosporine A. The mixtures possess enhanced efficacy and reduced toxicity over the individual isomers and over naturally occurring and other presently known cyclosporines and cyclosporine derivatives. Embodiments of the present invention are directed toward cis and trans-isomers of cyclosporin A analogs referred to as ISA TX 247, and derivatives thereof. Mixtures of ISA TX 247 isomers exhibit a combination of enhanced potency and reduced toxicity over the naturally occurring and presently known cyclosporins. ISA TX 247 isomers and alkylated, arylated, and deuterated derivatives are synthesized by stereoselective pathways where the particular conditions of a reaction determine the degree of stereoselectivity. The ratio of isomers in a mixture comprises greater than about 80 percent by weight of the E-isomer and less than about 20 percent by weight of the Z-isomer, based on the total weight of the mixture.
    这项发明涉及与环孢霉素A结构相似的环孢霉素类似物的异构混合物。这些混合物具有比单个异构体以及自然存在和其他目前已知的环孢霉素和环孢霉素衍生物具有增强的功效和降低毒性。本发明的实施例涉及被称为ISATX247的环孢霉素A类似物的顺式和反式异构体,以及其衍生物。ISATX247异构体的混合物表现出比自然存在和目前已知的环孢霉素具有更强效和降低毒性的组合。ISATX247异构体和烷基化、芳基化和氘化衍生物是通过立体选择性途径合成的,其中反应的特定条件决定了立体选择性的程度。混合物中异构体的比例包括E-异构体的重量大约超过80%,Z-异构体的重量小于混合物的总重量的20%。

  • Titanium-Mediated Fragment Union Processes in Complex Molecule Synthesis: Development of a Branched Reaction Pathway of High Step Economy for the Synthesis of Complex and Diverse Polyketides
    作者:Glenn Micalizio、Lark Perez
    DOI:10.1055/s-2008-1032160
    日期:2008.2
    We describe a synthetic pathway to structurally complex and diverse polyketides based, in part, on regio- and stereoselective titanium-mediated coupling reactions. The sequences described allow for rapid assembly of polyketide-inspired architecture while providing significant flexibility for the establishment of diverse stereochemical relationships and substitution patterns along the carbon backbone (including stereodefined alkenes and 1,3-dienes, saturated and unsaturated lactones, hemiketals, α,β-unsaturated carbonyls, and spiroketals).
    我们描述了一条合成路径,用于合成结构复杂且多样的多酮类化合物,部分基于区位和立体选择性的钛介导耦合反应。所描述的合成序列允许快速组装多酮类启发的结构,同时在碳主链上建立多样的立体化学关系和取代模式(包括立体定义的烯烃和1,3-二烯、饱和和不饱和内酯、半缩醛、α,β-不饱和碳基化合物以及螺环醇)。
