Abstract
Four new sesquiterpene lactones, 8α-(2'Z-tigloyloxy)-hirsutinolide (1), 8α-(2'Z-tigloyloxy)-hirsutinolide-13-O-acetate (2), 8α-(4-hydroxytigloyloxy)-hirsutinolide (3), and 8α-hydroxy-13-O-tigloyl-hirsutinolide (4), along with seven known derivatives (5-11), three norisoprenoids (12-14), a flavonoid (15), and a linoleic acid derivative (16), were isolated from the chloroform partition of a methanol extract from the combined leaves and stems of Vernonia cinerea. Their structures were established by 1D and 2D NMR, UV, and MS analyses. Compounds 1-16 were evaluated for their inhibitory effects against the viability of U251MG glioblastoma and MDA-MB-231 breast cancer cells that harbour aberrantly-active STAT3, compared to normal NIH3T3 mouse fibroblasts that show no evidence of activated STAT3. Among the isolates, compounds 2 and 7 inhibited the aberrant STAT3 activity in glioblastoma or breast cancer cells. Further, compounds 7 and 8 inhibited viability of all three cell lines, compounds 2, 4, and 9 predominantly inhibited the viability of the U251MG glioblastoma cell line.

Abstract
Hydroxy fatty acids are widely used in chemical, food, and cosmetic industries as starting materials for the synthesis of polymers and as additives for the manufacture of lubricants, emulsifiers, and stabilizers. They have antibiotic, anti-inflammatory, and anticancer activities and therefore can be applied for medicinal uses. Microbial fatty acid-hydroxylation enzymes, including P450, lipoxygenase, hydratase, 12-hydroxylase, and diol synthase, synthesize regio-specific hydroxy fatty acids. In this article, microbial fatty acid-hydroxylation enzymes, with a focus on region-specificity and diversity, are summarized and the production of mono-, di-, and tri-hydroxy fatty acids is introduced. Finally, the production methods of regio-specific and diverse hydroxy fatty acids, such as gene screening, protein engineering, metabolic engineering, and combinatory biosynthesis, are suggested.

Abstract
This paper reviews Bacillus genes encoding monooxygenase enzymes producing unique fatty acid metabolites. Specifically, it examines standard monooxygenase electron transfer schemes and related domain structures of these fused domain enzymes on route to understanding the observed oxygenase activities. A few crystallographic analyses of the standard bearer enzyme P450(BM-3) are discussed to try to rationalize the common chemistries of this important enzyme family. Detailed P450(BM-3) enzyme activities toward different substrates and the unique substrate-specific primary oxidation products are examined. A few orthologs to the recurring P450(BM-3) enzyme as well as related small single-to-triple nucleotides changed mutants are also discussed. Finally, preliminary data characterizing unique in vivo-based primary and secondary products of a novel ortholog, the ALA2 strain, are presented. This later strain synthesizes several unique multi-oxidized reaction products that require additional study to further understand. It is hoped that a better understanding of these oxygenase reactions, particularly the ALA2 strain, will allow for realistically priced production of target multiple-oxygenated compounds with potential uses as specialty chemicals or as therapeutic agents.

Abstract
In previous studies, a new microbial strain ALA2 was isolated which produced many new products from linoleic acid [Gardner H.W., Hou C.T., Weisleder D. and Brown W. 2000. Lipids 35: 1055-1060; Hou C.T. 1998. 12,13,17-Trihydroxy-9(Z)-Octodecenoic acid and derivatives and microbial isolate for production of the acid. US Patent No. 5, 852, 196]. Strain ALA2 was preliminary identified as Clavibacter sp. based on its physiological and fatty acid profiles. To determine if strain ALA2 is the optimal strain for industrial applications, other related strains were screened for their abilities to convert linoleic acids. Two strains from Clavibacter and 20 type strains from the phylogenetically related genus Microbacterium were studied. Surprisingly, all of these strains tested showed very little or no activity in converting linoleic acid. On reexamination of the identification of strain ALA2, the sequence of the 16S ribosomal RNA gene of ALA2 was found to be 99% identical to that of Bacillus megaterium and the strain was also found to have 76.3% DNA homology to the B. megaterium type strain. Therefore, strain ALA2 is now reclassified as B. megaterium. Screening of 56 strains of B megaterium strains showed that many of them were able to produce reasonable amounts of hydroxyl fatty acids from linoleic acid, although strain ALA2 possessed the greatest activity.

Abstract
Previously, it was reported that a newly isolated microbial culture, Clavibacter sp. strain ALA2, produced trihydroxy unsaturated fatty acids, diepxoy bicyclic fatty acids, and tetrahydroxyfuranyl fatty acids (THFAs) from linoleic acid (C. T. Hou, J. Am. Oil Chem. Soc. 73:1359-1362, 1996; C. T. Hou and R. J. Forman III, J. Ind. Microbiol. Biotechnol. 24:275-276, 2000; C. T. Hou, H. Gardner, and W. Brown, J. Am. Oil Chem. Soc. 75:1483-1487, 1998; C. T. Hou, H. W. Gardner, and W. Brown, J. Am. Oil Chem. Soc. 78:1167-1169, 2001). In this study, we found that Clavibacter sp. strain ALA2 produced novel THFAs, including 13,16-dihydroxy-12-THFA, 15-epoxy-9(Z)-octadecenoic acid (13,16-dihydroxy-THFA), and 7,13,16-trihydroxy-12, 15-epoxy-9(Z)-octadecenoic acid (7,13,16-trihydroxy-THFA), from alpha-linolenic acid (9,12,15-octadecatrienoic acid). The chemical structures of these products were determined by gas chromatography-mass spectrometry and proton and (13)C nuclear magnetic resonance analyses. The optimum incubation temperature was 30 degrees C for production of both hydroxy-THFAs. 13,16-Dihydroxy-THFA was detected after 2 days of incubation, and the concentration reached 45 mg/50 ml after 7 days of incubation; 7,13,16-trihydroxy-THFA was not detected after 2 days of incubation, but the concentration reached 9 mg/50 ml after 7 days of incubation. The total yield of both 13,16-dihydroxy-THFA and 7,13,16-trihydroxy-THFA was 67% (wt/wt) after 7 days of incubation at 30 degrees C and 200 rpm. In previous studies, it was reported that Clavibacter sp. strain ALA2 oxidized the C-7, C-12, C-13, C-16, and C-17 positions of linoleic acid (n-6) into hydroxy groups. In this case, the bond between the C-16 and C-17 carbon atoms is saturated. In alpha-linolenic acid (n-3), however, the bond between the C-16 and C-17 carbon atoms is unsaturated. It seems that enzymes of strain ALA2 oxidized the C-12-C-13 and C-16-C-17 double bonds into dihydroxy groups first and then converted them to hydroxy-THFAs.
