Arahypin-16 (1), a new prenylated resveratrol with a unique dihydrobenzofuran ring, has been isolated as a microbial metabolite of resveratrol (2) from whole-cell fermentation of Aspergillus sp. SCSIOW2. The stereochemistry of 1 was determined by ECD calculations. 1 showed about half of the extracellular radical scavenging effect (IC50 = 161.4 μM) compared with resveratrol (IC50 = 80.5 μM), while on biomembranes it exhibited the same range of protection effects against free radicals generated from AAPH (IC50 = 78.6 μM and 87.9 μM).
Arahypin - 16(1)是一种新的带有独特二氢苯并呋喃环的异戊烯基化白藜芦醇,它是从曲霉属真菌SCSIOW2的全细胞发酵中作为白藜芦醇(2)的微生物代谢产物分离得到的。1的立体化学结构通过电子圆二色(ECD)计算确定。与白藜芦醇(IC50 = 80.5 μM)相比,1表现出约一半的细胞外自由基清除效果(IC50 = 161.4 μM),而在生物膜上,它对2,2'-偶氮二异丁基脒二盐酸盐(AAPH)产生的自由基表现出相同范围的保护作用(IC50 = 78.6 μM和87.9 μM)。
