  Mitochondrial Affinity of Guanidine-rich Molecular Transporters Built on Monosaccharide Scaffolds: Stereochemistry and Lipophilicity

  摘要：

  我们合成了八种基于四种不同单糖支架的G8分子转运体（MTs），并研究了它们的生物特性，特别关注可能的线粒体靶向性和组织选择性。这些MT的线粒体亲和力明显与支架的立体化学相关，也与疏水性有一定联系。可以建议，在针对大脑和线粒体疾病的药物实际递送策略中，应将血脑屏障渗透性和线粒体亲和力视为关键参数，并且通过进一步研究富含胍的分子转运体的结构—性质关系，增强线粒体亲和力是可行的。

• Homogeneous Gold-Catalyzed Glycosylations in Continuous Flow

  The use of versatile alkynyl-building blocks that are activated by gold(I)-catalysis is demonstrated to efficiently generate a variety of glycosides in continuous flow. The application of a continuous flow setting to gold(I)-catalyzed glycosylations enables very short reaction times and excellent control of the reaction conditions.
• Synthetic studies toward pyruvate acetal containing saccharides. Synthesis of the carbohydrate part of the Mycobacterium smegmatis pentasaccharide glycolipid and fragments thereof for the preparation of neoantigens

  A series of 2,3-di-O-benzoyl-4,6-O-[(S)-1-(methoxycarbonyl)ethylidene]-D-glucopyranosyl donors (beta-phenylthio 3, bromide 4, alpha-chloride 5, beta-fluoride 6, and trichloroacetimidate 7) were prepared from the corresponding alpha-allyl glucoside 1 via the deallylated glucose 2 and were tested in glycosylation reactions with methanol to give the pyruvylated methyl glucosides 8 and 9 and with methyl 2,4,6-tri-O-benzoyl-beta-D-glucopyranoside 10 to give the disaccharide 11. Best results with respect to yield and beta-selectivity of the coupling were achieved with imidate 7. Thus, the 2-O-benzoyl-4,6-O-[(S)-1-(methoxycarbonyl)ethylidene]-3-O-methyl-D-glucopyranosyl trichloroacetimidate 14 was prepared from its benzyl glucoside 12 and used for the synthesis of fragments related to the Mycobacterium smegmatis lipopentasaccharide. Trimethylsilyl trifluoromethanesulfonate-mediated condensation of 14, 5-[(benzyloxycarbonyl)amino]pentanol, and 10, respectively, followed by deblocking of the products 15 and 17 gave the pyruvylated aminopentyl glucoside 16 and methyl laminaribioside 18. Treatment of 17 with dichloromethyl methyl ether gave the laminaribiosyl chloride 19, coupling of which with protected 5-aminopentanol gave 20 also obtained from 14 and the monosaccharide nucleophile 26. The trisaccharide 5-aminopentyl glycoside fragment 42 was prepared by first coupling of 14 and benzyl 2-O-benzoyl-4,6-O-[(S)-1-(methoxycarbonyl)ethylidene]-alpha-D-glucopyranoside 30 that was converted to the bispyruvylated laminaribiose imidate 33, followed by condensation with thioglycoside 38 obtainable in four steps from 1,2,4,6-tetra-O-acetyl-3-O-benzyl-beta-D-glucopyranose to give the trisaccharide ethyl thioglycoside 40. Next, NIS-mediated condensation of 40 and 5-[(benzyloxycarbonyl)amino]pentanol followed by deblocking gave 42. Pentasaccharide 45 was similarly prepared from 40 and hepta-O-benzoyltrehalose 43 to give first the blocked saccharide 44, deblocking of which afforded the target pentasaccharide.

  We synthesized eight G8 molecular transporters (MTs) based on 4 different monosaccharide scaffolds, and studied their biological properties with a special focus on possible mitochondrial targeting and tissue selectivity. The mitochondrial affinity of these MTs was found to be clearly related to the scaffold stereochemistry and also tenuously with the lipophilicity. It may be suggested that in the practical delivery strategy of drugs for the brain and mitochondrial diseases the BBB permeability and mitochondrial affinity should be considered as key parameters, and that an enhanced mitochondrial affinity appears possible by further research on the structure-property relationship of guanidine-rich molecular transporters.
