GRAPHICAL ABSTRACT

ABSTRACT

Two new 2(1H)-pyrazinone derivatives, 3,6-diisopropyl-5-methylpyrazin-2(1H)-one (1) and 5-(hydroxymethyl)-3,6-diisopropylpyrazin-2(1H)-one (2), were isolated from the fermentation broth of endophytic actinomycete Streptomyces sp. KIB-H1992. Their structures were established based on the detailed spectroscopic analyses, including ESI-MS, HR-ESI-MS, 1D- and 2D NMR spectra.
