  摘要：

  我们合成了两个新系列的融合杂己基双膦酸盐（5、8），它们在结构上与incadronate（YM175）和相关化合物有很大不同，并利用甲状旁腺激素（PTH）诱导的大鼠高钙血症模型（PIH 模型）对它们的抗骨吸收活性进行了评估。在这些化合物中，有几种表现出比帕米膦酸钠更强的抗骨吸收活性。其中，[1-羟基-2-（咪唑并[1，2-α]吡啶-3-基）亚乙基]双膦酸（5b，minodronate）不仅在 PIH 模型中，而且在大鼠固定骨萎缩模型（DA 模型）中的活性都比帕米膦酸高出 100 倍，因此被选中用于临床开发。本文讨论了这些新系列双膦酸盐的结构-活性关系。

• Modulation of Amyloidogenic Protein Self-Assembly Using Tethered Small Molecules

  Protein-protein interactions (PPIs) are involved in many of life's essential biological functions yet are also an underlying cause of several human diseases, including amyloidosis. The modulation of PPIs presents opportunities to gain mechanistic insights into amyloid assembly, particularly through the use of methods which can trap specific intermediates for detailed study. Such information can also provide a starting point for drug discovery. Here, we demonstrate that covalently tethered small molecule fragments can be used to stabilize specific oligomers during amyloid fibril formation, facilitating the structural characterization of these assembly intermediates. We exemplify the power of covalent tethering using the naturally occurring truncated variant (ΔN6) of the human protein β2-microglobulin (β2m), which assembles into amyloid fibrils associated with dialysis-related amyloidosis. Using this approach, we have trapped tetramers formed by ΔN6 under conditions which would normally lead to fibril formation and found that the degree of tetramer stabilization depends on the site of the covalent tether and the nature of the protein-fragment interaction. The covalent protein-ligand linkage enabled structural characterization of these trapped, off-pathway oligomers using X-ray crystallography and NMR, providing insight into why tetramer stabilization inhibits amyloid assembly. Our findings highlight the power of "post-translational chemical modification" as a tool to study biological molecular mechanisms.
• Identification of non-peptidic cysteine reactive fragments as inhibitors of cysteine protease rhodesain

  Rhodesain, the major cathepsin L-like cysteine protease in the protozoan Trypanosoma brucei rhodesiense, the causative agent of African sleeping sickness, is a well-validated drug target. In this work, we used a fragment-based approach to identify inhibitors of this cysteine protease, and identified inhibitors of T. brucei. To discover inhibitors active against rhodesain and T. brucei, we screened a library of covalent fragments against rhodesain and conducted preliminary SAR studies. We envision that in vitro enzymatic assays will further expand the use of the covalent tethering method, a simple fragment-based drug discovery technique to discover covalent drug leads.
