Discovery of novel non-peptidic β-alanine piperazine amide derivatives and their optimization to achiral, easily accessible, potent and selective somatostatin sst1 receptor antagonists
摘要:
Structural simplification of the core moieties of obeline and ergoline somatostatin sst(1) receptor antagonists, followed by systematic optimization, led to the identification of novel, highly potent and selective sst(1) receptor antagonists. These achiral, non-peptidic compounds are easily prepared and show promising PK properties in rodents. (C) 2009 Elsevier Ltd. All rights reserved.

A new class of liquid polysiloxane materials obtainable from cost-effective commodity precursors allow tailoring a plurality of (multi)-functional properties. The materials are classified in terms of their chemical identity, which comprises Q-type non-organofunctional, T-type monoorganofunctional and optional D-type diorganofunctional moieties. The T-type organofunctional species within a polymeric MBB can be present in various preferred combinations defined by spatial, stereochemical and compositional factors. The corresponding method of production for the liquid polymeric polysiloxanes involves a scalable, non-hydrolytic acetic anhydride method either in a simple one-step format to create statistically distributed "core-only" hyperbranched poly-alkoxysiloxanes or as a two- or multistep process to create "core-shell" materials.
一类新型液态聚硅氧烷材料可从具有成本效益的商品前体中获得,可定制多种(多功能)特性。这些材料按其化学特性分类,包括 Q 型非有机官能团、T 型单有机官能团和可选的 D 型二有机官能团。聚合物 MBB 中的 T 型有机官能团可以通过空间、立体化学和组成因素确定的各种优选组合出现。液态聚合聚硅氧烷的相应生产方法包括一种可扩展的非水解醋酸酐方法,该方法可以是简单的一步法,用于生产统计分布的 "纯核 "超支化聚烷氧基硅氧烷;也可以是两步法或多步法,用于生产 "核壳 "材料。
