The present invention relates generally to the field of anti-infective, anti-proliferative, anti-inflammatory, and prokinetic agents. More particularly, the invention relates to a family of bifunctional compounds useful as therapeutic agents. These compounds have both a macrolide ring and at least one heterocyclic moiety. The present invention further relates to processes for the preparation of such compounds, to intermediates useful in their preparation, to the use of the compounds as therapeutic agents, and to pharmaceuticals compositions containing them.

Structure–activity relationships for inhibitors of Pseudomonas aeruginosa exoenzyme S ADP-ribosyltransferase activity
recombinant ExoS ADPRT domain. Herein, we report structure–activity relationships of this compound class by comparing a total of 51 compounds based on a thieno [2,3-d]pyrimidin-4(3H)-one and 4-oxo-3,4-dihydroquinazoline scaffolds. Improved inhibitors with in vitro IC50 values of 6 μM were identified. Importantly, we demonstrated that the most potent inhibitors block ADPRT activity of native full-length
在感染期间,革兰氏阴性机会性病原体铜绿假单胞菌利用其III型分泌系统将毒素外切酶S(ExoS)转移到真核宿主细胞的细胞质中。ExoS是一种必不可少的体内毒力因子,可使铜绿假单胞菌避免吞噬作用并最终杀死宿主细胞。ExoS主要通过ADP-核糖基转移酶(ADPRT)活性引起其致病性。我们最近鉴定了具有体外IC 50的新型ExoS ADPRT抑制剂使用重组ExoS ADPRT结构域进行酶促测定时,大约20μM的核酸。在这里,我们通过比较基于噻吩并[2,3- d ]嘧啶-4(3 H)-one和4-oxo-3,4-dihydroquinazoline支架的51种化合物来报告该化合物类别的结构-活性关系。鉴定出体外IC 50值为6μM的改良抑制剂。重要的是,我们证明了最有效的抑制剂在酶促试验中能阻断铜绿假单胞菌分泌的天然全长ExoS的ADPRT活性,IC 50值为1.3μM 。该化合物类别有望成为开发新型抗菌剂的起点。
