据报道,从1-或d-丝氨酸和乙醛酸乙酯开始直接合成(S)-和(R)-N -Boc-5-氧代-哌嗪-2-羧酸。通过1 H NMR光谱研究它们的二级结构,将它们评估为两个四肽的组成。在Boc-Val-(S)-PCA-Gly-Leu-OMe的情况下,观察到两个易于相互转化的构象(比例为40%:60%),不同之处在于叔酰胺键的顺式-反式异构化,而Boc-Val-(R)-PCA-Gly-Leu-OMe在γ-转角和II型β-转角构象之间显示出平衡。
A straightforward synthesis of (S)- and (R)-N-Boc-5-oxo-piperazine-2-carboxylic acid is reported starting from l- or d-serine and ethyl glyoxylate. Those were evaluated as constituents in two tetrapeptides by studying their secondary structure by 1H NMR spectroscopy. In the case of Boc-Val-(S)-PCA-Gly-Leu-OMe, two readily interconverting conformations (in a 40%:60% ratio) were observed, differing for

The present disclosure relates to compounds which modulate the activity of Toll-like receptor (TLR) proteins, including agonists or activators, partial agonists, and antagonists. Of particular interest of compounds that modulate the activity of TLR2, as well as methods of using such compounds to treat cancer and other disorders associated with a TLR2 pathway.
