Texto completo(–)-Callystatin A is a bioactive marine natural product. Our interest in the total synthsis of Callystatin A was triggered by its inherent complexity and potent biological activities. This thesis starts with a bibliographic part devoted to the previously reported nine total syntheses of Callystatin A and an overview of the use of meso compounds desymmetrisation in total synthesis. Our convergent synthesis is based on the original synthesis of three main fragments. The Western one was obtained by an enantioselective desymmetrisation of a meso diol and a diastereoselective crotylation to form the polypropionate part. A [2+2] cycloaddition and a translactonization of a β-lactone led the δ-lactone unit of the Eastern moiety. The Central part was obtained in its racemic form. Our strategy was validated by the backbone synthesis precursors. A palladium-mediated coupling combined with an olefination reaction should afford the target

Texto completoOur PhD work is in the process of valorization of the Cambodian plant biodiversity. The objectives focused on phytochemical and pharmacological studies of two Cambodian plants of the Vernonia genus: Vernonia cinerea and Vernonia elliptica.An analytical HPLC method was developed and validated to quantify the major compound 8α-tigloyloxyhirsutinolide 13-O-acetate (H1) of Vernonia cinerea. We found that the compound H1 content ranges from 0.08% to 0.17% in samples collected from cambodian regions. We thus evaluated the anti-proliferative activity in vitro of extracts of V. cinerea and H1 compound against two human cancer cell lines HT29 and HepG2. For HepG2 cell line, the compound H1 has a similar IC50 to the positive control 5FU, 4.3 ± 0.2 versus 5.4 ± 0.9 µM. The interesting results on V. cinerea encouraged us to study other species of Vernonia genus growing in Cambodia, Vernonia elliptica. The phytochemical study conducted on this plant led to isolate a lignan [(+)-syringaresinol] and two sesquiterpene lactones [(+)-8,13-diacetyl-piptocarphol and Glaucolide B]. These compounds were described in this plant for the first time. The in vitro study of the anti-proliferative activity of the extracts of V. elliptica shows that the dichloromethane extract obtained from aqueous extract is very active

Four new diterpenoids, cespitulactones A-B (1-2), C4B1 (7) and E3A (8), were isolated from the soft coral Cespitularia taeniata collected in Taiwan, at a depth of 25 m, together with five known compounds, cespitularin F (3), 6-O-acetylcespitularin F (4), cespitularin D (5), flaccidoxide-13-acetate (6) and florlide A (9). Compound 1 possesses a novel structure with a bond cleavage between C-10 and C-11, and having a 14-membered lactone ring junction between C-10 and C-12. Compounds 2 and 8 have the verticillane skeleton, and compound 9 possesses the cespitularane skeleton. Their structures were elucidated on the basis of extensive spectroscopic analysis and chemical derivatization. The isolated compounds were also evaluated for cytotoxicity toward human cancer cell lines. Compound 1 exhibited significant cytotoxicity against human cervical epitheloid carcinoma (HeLa) and colon adenocarcinoma (DLD-1) cancer cells with IC50 of 3.69 and 9.98 μg/mL, respectively. Flaccidoxide-13-acetate (6) showed mild activity against human medulloblastoma (Daoy) and colon (WiDr) cancer cells at 16.9 and 13.8 μg/mL, respectively.

Sesquiterpene lactones contain α,β-unsaturated-γ-lactone as a major structural feature, which in recent studies have been shown to be associ- ated with anti-tumor, cytotoxic, anti-microbial and phytotoxic activities. Previous researchers isolated sesquiterpene lactones from Eupatorium formosanum Hay. Thus, we studied Eupatorium hualienense, a unique speces in Taiwan that grows near the eastern coast. Five new sesquiter- pene lactones of the germacranolide type, eupahualins A-E (1-5) along with the known lactone, eupasimplicin B (6). Their structures were determined by 1D-NMR(1H-NMR,13C-NMR) and 2D-NMR(COSY、NOESY、HMQC、HMBC). Eupahualin A (1) exhibits an aldehyde at C-10 and an a,b-unsatura ted acyl group at C-8. Eupahualin B (2) also has an aldehyde at C-10. The Z-form of C-4, C-5 double bond in eupahualin B (2) is the main difference from the trans-form C-4, C-5 double bond in eupahualin A (1). The difference of eupahualin C (3) and eupahualin A (1) lies in structure of a ester group at C-8. The methyl at C-4'''' in eupahualin A (1) was changed into hydroxy methyl while the hydroxy methyl of eupahualin A (1) was changed to methyl in eupahualin C (3). Eupahualin D (4) shows exocyclic double bond at C-10, OH at C-1 and OAc at C-3. An carboxylic group (COOH) at C-10 in eupahualin E (5) is the only difference from which in eupahualin A (1).

Vernonia cinerea Less. (Compositae) is an annual herb which is used medicinally for a variety of purposes, including reducing fever, and promoting digestion. Previous investigations have shown that crude extracts of V. cinerea possess analgesic, antipyretic, antimalarial, antimicrobial, and cytotoxic activities. By a series of chromatography and bioassay-directed fractionation, seventeen hirsutinolide-type sesquiterpene lactones containing six new compounds, vernolides-E~J (V1~V6), eleven known ones, 8α-(2-methylacryloyloxy)-1β,4β-epoxy-1α-methoxy-13-O-acetate- 10βH-germacra-5E,7(11)-dien-12,6-olide (V7), vernolide-B (V8) , hirsutinolide 13-O-acetate (V9), 8α-(2-methylacryloyloxy)-hirsutinolide-13-O- acetate (V10), 8α-tigloyloxyhirsutinolide-13-O-acetate (V11), vernolide-A (V12), 8β-(2-methylacryloloxy)-1-O-methyl-hirsutinolide (V13), 8α-(2-hydroxymethacryloyloxy)-hirsutinolide-13-O-acetate (V14), vernobockolide B (V15), vernolide-D (V16), and 8α-tiglogloxy-hirsutinolide (V17), together with six flavonoids, 6,7,8,4'-tetramethoxyflavone (V18), 5,6,7,4'-tetramethoxyflavone (V19), 6,7,8,3',4'-pentamethoxyflavone (V20), apigenin (V21) , luteolin-7-O-β-D-glucopyranoside (V22), and genkwanin (V23) were isolated from 95% EtOH extract of Taiwanese V. cinerea. Structural elucidation of these compounds were based on spectroscopic analyses (MS, UV, IR, and NMR techniques), as well as comparison with the reported data. Cytotoxic assay showed that compounds V3, V4, V7, V8, V11, and V16 possess cytotoxicity against four human tumor cell lines (HEp-2, WiDr, A549, Hep-G2, ED50: 17~39 μM). The inhibitory effects on nitric oxide (NO) produced by RAW264.7 macrophages in response to lipopolysaccharide (LPS) showed that V3, V4, V7, V8, and V11 (IC50: 0.2~1.9 μM) have potent anti-inflammatory activity. These results indicated that the bioactive isolates from V.cinerea could be served as lead compounds for the development of anti- inflammatory drug.
