The present invention relates to cyclopentanone derivatives of formula (I), their method of synthesis and uses thereof. Concretely, the compounds disclosed have proved to be inhibitors of glycogen synthase kinase 3β, GSK-3 β, which is known to be involved in different disease and conditions, such as Alzheimer's disease or non-insulin dependent diabetes mellitus. The present invention also relates to pharmaceutical compositions comprising the same. Further, the present invention is directed to the use of the compounds in the manufacture of a medicament for the treatment and/or prevention of a GSK-3 mediated disease or condition.

In a three-step protocol involving regioselective enzymatic acylation, per-O-trimethylsilylation, and a one-pot α-glycosidationâdeprotection sequence, cholesteryl-6-O-tetradecanoyl-α-D-glucopyranoside (α-CAG) of Helicobacter pylori is afforded starting from glucose in an overall yield of 45%. The production of CAG can be scaled to make purified quantities available to the biological community for the first time.

complicated due to its complex composition. All of the current PSG methods are demonstrated with refined oils or do not employ eco-friendly methods like enzymatic synthesis. Our current project entails studying sugar alcohol-derived amphiphiles for their phase-selective gelation in crude oil; the PSGs are derived from renewable, benign materials and synthesized via a simple, single-step, enzymatic
the development of new materials that can act as scaffolds for in situ tissue regeneration and regrowth is necessary. In this report, we present a new class of injectable oleogel and composite gel derived fromglycolipids that provide reversible interlinked 3D fiberous network architecture for effective wound closure by tissue regrowth and regeneration. Glycolipids were derived from α-chloralose and
在发展中国家,伤口是一个主要的健康问题,是一个重大问题。因此,有必要开发可作为原位组织再生和再生支架的新材料。在本报告中,我们提出了一种新的可注射油凝胶和源自糖脂的复合凝胶,它们提供可逆的互连 3D 纤维网络结构,通过组织再生和再生来有效闭合伤口。使用 Novozyme 435(一种来自南极假丝酵母的固定化脂肪酶 B)从 α-氯醛糖和各种乙烯基酯中提取糖脂作为催化剂,收率良好。这些糖脂在石蜡油中发生自发自组装形成油凝胶,其中姜黄素成功掺入以产生复合凝胶。油凝胶和复合凝胶的形态分析清楚地揭示了 3D 纤维网络的形成。流变学研究揭示了油凝胶和复合凝胶在各种实验条件下的热和机械加工性能。有趣的是,开发的可注射油凝胶和复合凝胶能够通过调节炎症、细胞增殖和细胞外基质重塑的重叠阶段来加速伤口愈合过程。由于氯醛糖具有麻醉特性,本研究将为未来开发麻醉伤口愈合油凝胶建立新策略。

the TAGs possess two different saturated fatty acyl groupslocated in the sn-1 and sn-2 positions with an unsaturated fatty acyl group in the remaining sn-3 position of the glycerol skeleton, whereas the remaining four possess two different saturated acyl groups in the terminal sn-1 and sn-3 positions with an unsaturated acyl group in the sn-2 position. The former group was synthesised by a six-step
