  摘要：

  制备了19种具有吡啶基、吡咯基、咪唑基、吡唑基、哌啶基、哌嗪基和吡咯烷基部分结构的低聚胺。其中13种在20-80μmol/L的浓度下半数抑制胶原诱导的血小板聚集。在低聚胺的疏水取代基中引入碱性 (pKB <7) 功能通常会导致有效性急剧下降。胺官能团之间的杂芳族间隔基与碳芳族系统相比没有优势。

  A modified conjugated diene-based polymer having high Mooney viscosity and good shape stability and exhibiting excellent processability and low heat build-up is obtained in as few steps as possible. The modified conjugated diene-based polymer is produced by a method of reacting a conjugated diene-based polymer having an active chain end, obtained by polymerizing a monomer containing a conjugated diene compound in the presence of an initiator that contains at least either of an alkali metal compound and an alkaline earth metal compound, with a compound [M] having at least two groups selected from the group consisting of a group “—C(R 1 )N-A 1 ” and a group “—N═C(R 1 )-A 1 ”, where R 1 is a hydrogen atom or a hydrocarbyl group and A 1 is a monovalent group having an alkoxysilyl group.

  A new class of imidazolines as 4-position acids or esters with very potent anti-inflammatory as well as antimicrobial activity is described. The synthesis of these imidazolines includes a multicomponent reaction applicable to a combinatorial synthetic approach. The combination of these two key characteristics provides an effective therapeutic drug in the treatment of septic shock as well as many other inflammatory (arthritis and asthma) and infectious disorders. The use of this novel class of non-steroidal agents as anti-inflammatory agents (for the treatment of asthma, etc.), antibacterial agents, and antiseptic agents is described. The compounds are also useful in the treatment of tumors (such as cancers). The imidazolines are potent inhibitors of the transcription factor NF-&kgr;B as well as potent activity against the Gram (+) bacterium. The compositions are also useful for treating autoimmune diseases and for inhibiting rejection of organ and tissue transplants.
