As a part of our continuing work to discover bioactive leading molecules from marine microorganism, ethyl acetate fraction of organic extract of the train Stachybotrys longispora FG216 showed fibrino.ytic activity in our primary screen. The bioassay-guided purification of the active fractions resulted in isolation of a new isoindolone, FGFC2 （1）（FGFC2, Fungi fibrino.ytic compound 2）, together with two kno.n compounds, LL-Zl272β （2） and ergosterol （3）. The structure of compound 1 was elucidated by the spectral analysis of 1D （^1H, ^13C） NMR, 2D （COSY, HSQC, and HMBC） and ESI-MS. Three compounds were evaluated for fibrino.ytic activities in vitro. Compared to FGFC1 （EC50=47 μmol/L） as a reference drug, compound 1 and ergosterol （3） showed moderate fibrino.ytic activities in vitro with EC50 values of 108.16 and 156.30 μmol/L, respectively. LL-Z127213 （2） had no.fibrino.ytic activity.

Background: There is increasing research interest in using short-chain fatty acids(SCFAs) including butyrate as potential alternatives to antibiotic growth promoters in animal production. This study was conducted to evaluate the effects of supplementation of sodium butyrate(SB) in liquid feeds(milk, milk replacer, and the mixture of both)on the growth performance, rumen fermentation, and serum antioxidant capacity and immuno.lobins in dairy calves before weaning. Forty healthy female Holstein calves(4-day-old, 40 ± 5 kg of body weight) were housed in individual hutches and randomly allocated to 1 of 4 treatment groups(n = 10 per group) using the RAND function in Excel. The control group was fed no.SB(SB0), while the other three groups were supplemented with 15(SB15),30(SB30), or 45(SB45) g/d of SB mixed into liquid feeds offered. The calves were initially fed milk only(days 2 to 20), then a mixture of milk and milk replacer(days 21 to 23), and finally milk replacer only(days 24 to 60).Results: The SB supplementation enhanced growth and improved feed conversion into body weight gain compared with the SB0 group, and the average daily gain increased quadratically with increasing SB supplementation. no.significant effect on rumen pH;concentrations of NH_3-N, individual and total VFAs;or acetate:propionate(A:P) ratio was found during the whole experimental period. Serum glutathione peroxidase activity increased linearly with the increased SB supplementation, while the serum concentration of maleic dialdehyde linearly decreased. Serum concentrations of immuno.lobulin A, immuno.lobulin G, or immuno.lobulin M were no. affected by the SB supplementation during the whole experimental ***: Under the conditions of this study, SB supplementation improved growth performance and antioxidant function in pre-weaned dairy calves. We recommended 45 g/d as the optimal level of SB supplementation mixed into liquid feeds(milk or milk replacer) to improve the growth and ant
