The present invention relates to novel spiro-oxadiazoline compounds that are suitable as agonists or partial agonists of a7-nAChR, and pharmaceutical compositions of the same, methods of preparing these compounds and compositions, and the use of these compounds and compositions in methods of maintaining, treating and/or improving cognitive function. In particular, methods of administering a spiro-oxadiazoline cx7-nAChR agonist or partial agonist, to a patient in need thereof, for example a patient with a cognitive deficiency and/or a desire to enhance cognitive function, that may derive a benefit therefrom.
The synthesis and biologicalevaluation of analogues of uridylpeptide antibiotics were described, and the molecular interaction between the 3′-hydroxy analogue of mureidomycin A (3′-hydroxymureidomycin A) and its target enzyme, phospho-MurNAc-pentapeptide transferase (MraY), was analyzed in detail. The structure–activity relationship (SAR) involving MraY inhibition suggests that the side chain at the

heterocycles (triazoles, oxazoles, thiazoles, or pseudoprolines) along the macrocyclic backbone. The syntheses of these derivatives employ several approaches that can be applied to convert a macrocyclic peptide into its peptidomimetic counterpart. These approaches include peptide modifications to generate the alkyne and azide for click chemistry, a serine conversion into an oxazole, a Hantzsch reaction
与用肽类似物观察到的相比,基于肽模拟物的大环化合物通常具有改进的药代动力学特性。描述了基于活性 sansalvamide A 结构的 13 种拟肽衍生物的合成,其中这些类似物沿大环骨架包含杂环(三唑、恶唑、噻唑或假脯氨酸)。这些衍生物的合成采用了几种可用于将大环肽转化为其拟肽对应物的方法。这些方法包括肽修饰以生成用于点击化学的炔烃和叠氮化物、丝氨酸转化为恶唑、Hantzsch 反应生成噻唑以及保护苏氨酸生成假脯氨酸衍生物。此外,我们展示了两种不同的拟肽部分,三唑和噻唑,
Design and synthesis of new tripeptide-type SARS-CoV 3CL protease inhibitors containing an electrophilic arylketone moiety
We describe here the design, synthesis and biologicalevaluation of a series of molecules toward the development of novel peptidomimetic inhibitors of SARS-CoV 3CLpro. A docking study involving binding between the initial lead compound 1 and the SARS-CoV 3CLpro motivated the replacement of a thiazole with a benzothiazole unit as a warhead moiety at the P1′ site. This modification led to the identification

The first total synthesis of symplostatin 4, a marine cyanobacterium-derived natural product, is described. Notable features of the route include the efficient preparation of three key fragments and final assembly to the natural product via sequential imide and amide couplings. Symplostatin 4 was also demonstrated to possess significant antimalarial activity (ED50 of 74 nM against Plasmodium falciparum
