secondary metabolites produced by cellular slime molds to evaluate if they are valuable resources for biologically potential substances. From the methanol extract of fruiting bodies of Dicyostelium firmibasis, we obtained new α-pyranoids, dihydrodictyopyrones A (1) and C (2). Their structures including absolute configurations were determined by spectral means and asymmetric total synthesis. Compounds 1 and
我们已经探索了细胞粘液霉菌产生的次生代谢产物的多样性,以评估它们是否是生物潜在物质的宝贵资源。从果蝇双胞胎的子实体的甲醇提取物中,我们获得了新的α-吡喃类化合物,二氢双嘧啶酮A(1)和C(2)。它们的结构,包括绝对构型,是通过光谱方法和不对称总合成来确定的。化合物1和2是dictyopyrone家族的新成员,它们是Dictyostelium细胞粘液霉菌各种物种的特征性次生代谢产物。
