  Systematic Comparison of Sets of ¹³C NMR Spectra That Are Potentially Identical. Confirmation of the Configuration of a Cuticular Hydrocarbon from the Cane Beetle Antitrogus parvulus

  摘要：

  A systematic process is introduced to compare (13)C NMR spectra of two (or more) candidate samples of known structure to a natural product sample of unknown structure. The process is designed for the case where the spectra involved can reasonably be expected to be very similar, perhaps even identical. It is first validated by using published (13)C NMR data sets for the natural product 4,6,8,10,16,18-hexamethyldocosane. Then the stereoselective total syntheses of two candidate isomers of the related 4,6,8,10,16-pentamethyldocosane natural product are described, and the process is applied to confidently assign the configuration of the natural product as (4S,6R,8R,10S,16S). This is accomplished even though the chemical shift differences between this isomer and its (16R)-epimer are only ±5-10 ppb (±0.005-0.01 ppm).

  Discovery of an 8-Aza-5-thiaProstaglandin E1 Analog as a Highly Selective EP4 Receptor Agonist

  摘要：

  为了发现一种口服可用的EP4亚型选择性激动剂，合成并评估了一系列8-氮原子前列腺素E1（PGE1）类似物对PGE2受体亚型的亲和力。此外，还研究了这些化合物的结构-活性关系。在测试的化合物中，8-氮PGE1类似物6和8-氮-5-硫PGE1类似物12对EP4受体具有高效的亲和力、良好的功能活性和优异的亚型选择性。此外，这些类似物在人体肝微粒体中表现出良好的稳定性。因此，我们得出结论，这两系列的8-氮PGE1类似物可能是口服可用的EP4亚型选择性激动剂的有前景的化学先导物。

  Formation and behaviors of chiral aggregates of methylated tetraenoic fatty acids (TE-FAs) were reported. In the C-24 TE-FA series, the aggregate prepared by dispersing an ethanol stock solution of C-24 TE-FA 1b into sodium phosphate buffer gave a strong positive Cotton effect, whereas the aggregate prepared from a methanol stock solution gave a negative Cotton effect. In the C-20 TE-FA series, the

  甲基化的丁烯二酸（TE-FAs）的手性聚集体的形成和行为已有报道。在C-24 TE-FA系列中，通过将C-24 TE-FA 1b的乙醇储备溶液分散到磷酸钠缓冲液中制备的聚集体产生很强的棉花效应，而由甲醇储备溶液制备的聚集体产生负的棉花效应。棉花效果。在C-20 TE-FA系列中，由C-20 TE-FA 2b的乙醇储备溶液制得的聚集体表现出随时间变化的手性反转。[见文字]。

  For the purpose of discovering an orally available EP4 subtype-selective agonist, a series of 8-aza prostaglandin E1 (PGE1) analogs were synthesized and evaluated for their affinity for PGE2 receptor subtypes. Additionally, the structure–activity relationships of these compounds were studied. Among the tested compounds, the 8-aza PGE1 analog 6 and 8-aza-5-thiaPGE1 analog 12 had highly potent EP4 receptor affinity, good functional activity, and excellent subtype-selectivity. Furthermore, these analogs demonstrated good stability in human liver microsomes. As a result, we concluded that these two series of 8-aza PGE1 analogs could be promising chemical leads for an orally available EP4 subtype-selective agonist.
