A series of anacardic acid analogues possessing different side chains viz. phenolic, branched, and alicyclic were synthesized and their antibacterial activity tested against methicillin-resistant Staphylococcus aureus (MRSA). The maximum activity against this bacterium occurred with the branched side-chain analogue, 6-(4',8'-dimethylnonyl)salicylic acid, and the alicyclic side-chain analogue, 6-cyclododecylmethyl salicylic acid, with the minimum inhibitory concentration (MIC) of 0.39 microg/mL, respectively. This activity was superior to that of the most potent antibacterial anacardic acid isolated from the cashew Anacardium occidentale (Anacardiaceae), apple and nut, that is, the 6-[8'(Z),11'(Z),14'-pentadecatrienyl]salicylic acid.
合成了一系列具有不同侧链（即酚类、支链和脂环族）的腰果酚酸类似物，并测试了它们对耐甲氧西林金黄色葡萄球菌（MRSA）的抗菌活性。对该细菌具有最大活性的是支链侧链类似物6-(4',8'-二甲基壬基)水杨酸和脂环族侧链类似物6-环十二烷基甲基水杨酸，其最低抑菌浓度（MIC）分别为0.39μg/mL。该活性优于从腰果（漆树科）、苹果和坚果中分离出的最有效的抗菌腰果酚酸，即6-[8'(Z),11'(Z),14'-十五碳三烯基]水杨酸。
