, said medicament being preferably intended to regulate inflammatory mechanisms. The reducing sugar is preferably selected from the group containing rhamnose, fucose and glucose. The invention also relates to a cosmetic treatment method involving the topical application of a composition comprising at least one reducing alkyl-sugar monomer having a hydroxyl function which is substituted by an alkoxy radical at C

work, we synthetized new synthetic mono-rhamnolipids (smRLs) consisting in a rhamnose connected to a simple acyl chain and differing by the nature of the link and the length of the lipid tail. We then investigated the effects of these ether, ester, carbamate or succinate smRL derivatives on Botrytis cinerea development, symptoms spreading on tomato leaves and immuneresponses in tomato plants. Our results
天然鼠李糖脂是潜在的生物防治剂,可用于保护植物免受细菌和真菌病害。在这项工作中,我们合成了新的合成单鼠李糖脂 (smRLs),其中包含连接到简单酰基链的鼠李糖,其不同之处在于链接的性质和脂质尾的长度。然后,我们研究了这些醚、酯、氨基甲酸酯或琥珀酸酯 smRL 衍生物对灰霉病菌发育、番茄叶片上蔓延的症状和番茄植株免疫反应的影响。我们的结果表明,合成 smRL 能够在番茄中触发早期和晚期免疫相关的植物防御反应,并在受控条件下增加植物对 B. cinerea 的抗性。
