Abstract

Dibohemamines A-C (5-7), three new dimeric bohemamine analogues dimerized through a methylene group, were isolated from a marine-derived Streptomyces spinoverrucosus. The structures determined by spectroscopic analysis were confirmed through the semi-synthetic derivatization of monomeric bohemamines and formaldehyde. These reactions, which could occur under mild conditions, together with the detection of formaldehyde in the culture, revealed that this dimerization is a non-enzymatic process. In addition to the unique dimerization of the dibohemamines, dibohemamines B and C were found to have nm cytotoxicity against the non-small cell-lung cancer cell line A549. In view of the potent cytotoxicity of compounds 6 and 7, a small library of bohemamine analogues was generated for biological evaluation by utilizing a series of aryl and alkyl aldehydes.
