A new cytotoxic substance was isolated following acid treatment of fermented broth of a Streptomyces strain numbered MJ915-WF12. The structure was elucidated by spectroscopic analyses to be 5-dihydro-4-formyl-6-hydroxy-2-hydroxymethyl-6-methyl-2H-pyran. It was thought to be generated by dehydration and ring reformation of the precursor material in cultured broth by acid.
对编号为MJ915-WF12的链霉菌菌株发酵液进行酸处理后，分离出一种新的细胞毒性物质。通过光谱分析确定其结构为5-二氢-4-甲酰基-6-羟基-2-羟甲基-6-甲基-2H-吡喃。据认为它是由培养液中的前体物质经酸脱水和环化重排生成的。
