The present disclosure relates to novel pyridine-containing macrocyclic compounds and libraries thereof that are useful as research tools for drug discovery efforts. This disclosure also relates to methods of preparing these compounds and libraries and methods of using these libraries, such as in high throughput screening. In particular, these libraries are useful for evaluation of bioactivity at existing and newly identified pharmacologically relevant targets, including G protein-coupled receptors, nuclear receptors, enzymes, ion channels, transporters, transcription factors, protein-protein interactions and nucleic acid-protein interactions. As such, these libraries can be applied to the search for new pharmaceutical agents for the treatment and prevention of a range of medical conditions.

Simply reacting equal equivalents of symmetricdiamines with esters or carbonates in the presence of a suitable amount of water gave mono-acylated products in good to quantitative yields.
在适量的水存在下,简单地将等当量的对称二胺与酯或碳酸酯反应,即可得到定量产率良好的单酰化产物。
Novel method for the synthesis of urea backbone cyclic peptides using new Alloc-protected glycine building units
properties. Backbone cyclic peptides are prepared by the incorporation of special building units, capable of forming amide, disulfide and coordinative bonds. Urea bridge is often used for the preparation of cyclic peptides by connecting two amine functionalized side chains. Here we present urea backbone cyclization as an additional method for the preparation of backbone cyclic peptide libraries. A
Utilising alkyl phenyl carbonates, an economical, practical and versatile method for selective Boc, Cbz and Alloc protection of polyamines has been developed. This method allows Boc, Cbz and Alloc protection of primary amines in the presence of secondary amines by reaction of the polyamines with the alkyl phenyl carbonates. Also, this method allows mono carbamate protection of simple symmetrical aliphatic α,Ï-alkanediamines in high yields with respect to the diamine. Finally, the method allows selective carbamate protection of a primary amine located on a primary carbon in the presence of a primary amine located on a secondary or a tertiary carbon in excellent yields.

example to explore push–pull chromophores as privileged platforms for such “ion pair–π” interactions. In antiparallel orientation with respect to the push–pull dipole, a bathochromiceffect is observed. A red shift of 41 nm found in the least polar solvent is in good agreement with the 70 nm expected from theoretical calculations of ground and excited states. Decreasing shifts with solvent polarity, protonation
