Novel signaling molecule(s) that induce lankacidin and lankamycin production in Streptomyces rochei were extracted from the culture filtrate and purified by Sephadex LH20 and silica gel chromatography with the help of bioassay. Chiral HPLC and ESI-MS analyses indicated the presence of two active components, SRB1 and SRB2, and their molecular formulae were established to be C15H24O5 and C16H26O5, respectively. Based on extensive NMR analysis, SRB1 and SRB2 were determined to be 2-(1’-hydroxyl-6’-oxo-8’-methylnonyl)-3-methyl-4-hydroxybut-2-en-1,4-olide and 2-(1’-hydroxyl-6’-oxo-8’-methyldecyl)-3-methyl-4-hydroxybut-2-en-1,4-olide, respectively. These structures were finally confirmed by chemical synthesis and the absolute configuration of C-1’ was determined to be R. The synthetic 1’R-isomers induced production of lankacidin and lankamycin at around 40 nM concentration. Thus, SRB1 and SRB2 are distinct from the well-known 2,3-disubstituted γ-butyrolactone molecules such as A-factor, virginia butanolide, and SCB1 and belong to the γ-butenolide family following avenolide which has been recently isolated from Streptomyces avermitilis.
