This invention is related to the field of PCSK9 biology and the composition and methods of use of small molecule ligands for modulation of PCSK9 biological activity. In particular, the invention provides compositions of small molecule compounds that modulate circulating levels of low density lipoproteins by altering the conformation of the protein PCSK9. Binding these small molecule ligands to PCSK9 alters the conformation of the protein, modifying the interaction between PCSK9 and an endogenous low density lipoprotein receptor, and can lead to reduced or increased levels of circulating LDL-cholesterol. High LDL-cholesterol levels are associated with increased risk for heart disease. Low LDL-cholesterol levels may be problematic in other conditions, such as liver dysfunction; thus, there is also utility for small molecule ligands that can raise LDL levels.

A chemoselective strategy for oligosaccharide-peptide ligation is described in which alpha-thio analogues of mucin-related glycoconjugates can be readily accessed through site-selective conjugate addition of complex oligosaccharide thiolates to dehydroalanine-containing peptides. The efficiency of the ligation is highlighted by the rapid convergent assembly of thio-isosteres of the four tumor-associated
A concept for the rational design of sequence-selectivepeptide receptors has been extended: in addn. to recognitionmodules for polar, arom. and basic amino acids, the series has now been completed with new receptor units for apolar and acidic amino acids. The underlying strategy uses the intermol. b-sheet stabilization of a dipeptide as a prerequisite to bind its N-terminal amino acid side chain
合理设计序列选择性肽受体的概念已得到扩展:另外。到 polar、arom 的识别模块。和碱性氨基酸,该系列现在已经完成了新的非极性和酸性氨基酸受体单元。底层策略使用 intermol。二肽的 b 片层稳定性,作为通过从受体部分突出的 U 形转弯末端的战略性放置的识别尖端结合其 N 端氨基酸侧链的先决条件。因此,二氨基吡唑已通过环状酰亚胺共价连接到肯普氏三酸,而间位取代的苯胺作为酰胺偶联到第三个羧酸酯悬垂臂上,形成两个芳基。在紧密的构象锁定中将单位转换为子范德华距离。核磁共振滴定,Karplus 分析和蒙特卡洛模拟证明了丙氨酸-contg 的有效序列选择性识别。二肽。以前不存在这样一组合理设计的肽受体的例子。

Substrate mimicry: Substratepeptidomimetics were designed and showed potent inhibition of plasmepsinX (PMX). The peptidomimetics block PMX ligand processing, arrest asexual parasites at the schizont stage and potently kill P. falciparum parasites. The peptidomimetics will further assist in the understanding of PMX selectivity and in the development of PMX targeted antimalarials.
