Four analogues of ochratoxin A (OTA) differing for the aminoacidic moiety were synthesised using ochratoxin α (OTα) as the starting material. The condensation reaction between protected amino acids and OTα, carried out in the presence of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (EDC • HCl) and N-hydroxybenzotriazole (HOBt) as coupling agents, followed by deprotection and PTLC purification
赭曲霉毒素A(OTA)的四个不同的类似物为aminoacidic部分使用赭曲霉毒素合成α(OT α)作为起始材料。保护的氨基酸和OT之间的缩合反应α,在1-乙基-3-(3-二甲基氨基丙基)碳二亚胺盐酸盐(EDC•HCl)中和的存在下进行Ñ羟基苯并三唑(HOBt)作为偶联剂,接着脱保护和PTLC纯化得到OTA丙氨酸,亮氨酸,丝氨酸和在令人满意的产率色氨酸类似物(33-47%,基于OT α)。
