The cytotoxicities of 2 derivatives of artemisinin B and 2 derivatives of artemisic acid (designated as Compound A, B, C, and D) were investigated, using trypan blue dye exclusion test and colony-forming units assay. At the concentration of 5 micrograms.ml-1, the inhibition rates of these 4 compounds against murine leukemia cell line P388 were > 85%. When tested against human hepatoma cell line SMMC-7721 at 25 micrograms.ml-1, the inhibition rates of Compound A, B, C, and D were found to be 92.3%, 96.9%, 84%, and 82.1%, respectively, and 27%, 8%, 37.8%, 1.7% against normal human embryonic lung cell line WI-38, respectively. These 4 compounds all showed an inhibition rate of 100% against human gastric cancer cell line SGC-7901 at 50 micrograms.ml-1.

The present study establishes the in vitro system for studying the oncosuppression activity of parvovirus and discovers that parvovirus H-1 can be grown cytolytically in various human cancer cell lines, which include 4 hepatoma cell lines (QGY-7703, SMMC-7721, Bel-7402, PLC/PRF/5), 3 gastric cancer cell lines (SGC-7901, MGC-80-3, MKN-28) and 1 naspharynx cancer cell line (CNE). The growth of two primary gastric cancer cell cultures from surgical cancer tissue were also inhibited by the infection of H-1. The sensitivity of cancer cells to H-1 may relate to their differentiation states. On the contrary, H-1 can neither be grown cytolytically in normal liver or stomach cells, nor inhibit their growth. Transformation of human skin fibroblasts with Simian Virus 40 activated their sensitivity to H-1. Our results thus indicate that the antineoplastic activity of H-1 in vivo involves at least its direct inhibiting or killing malignant cells.

We have investigated the cytotoxic and antitumour activity of an octadecenoic acid extract, mainly containing oleic and linoleic acids, from Euphorbia kansui on human gastric (SGC-7901), hepatocellular carcinoma (BEL-7402), and leukaemia (HL-60) tumour cell strains. Significant and dose-dependent antiproliferation effects were observed on tumour cells from the dose of 3.2 microg mL(-1), which were comparable with or better than those of the common antitumour agent 5-fluorouracil. Results from the clone formation assay and flow cytometry indicated that the mixture of octadecenoic acids resulted in a dose-dependent reduction in the number of tumour cells and significantly inhibited cell proliferation, with induced apoptosis and G(0)/G(1) phase cell cycle arrest. Also, the octadecenoic acids could not only cause cell apoptosis/necrosis but also functionally and structurally damage the tumour cell membrane and cell ultra-structures. These observations encourage further clinical evaluation of the inhibitory effects of octadecenoic acids on various forms of cancer.

Reaction of di-n-butyltin(IV) dichloride with 4-chlorobenzohydroxamic acid at 1:1 ratio yielded a new mixed-ligand diorganotin(IV) complex, di-n-butyl-(4-chlorobenzohydroxamato)tin(IV) chloride(DBDCT). It was fully characterized by IR, (1)H, (13)C, (119)Sn NMR spectra and single crystal X-ray analysis. In DBDCT, the tin atom is five-coordinated in a trigonal bipyramidal geometry. DBDCT exhibited strong in vitro cytotoxic activity toward human immature granulocyte leukemia (HL-60), human salivary-gland carcinoma (SGC-7901), human henrietta carcinoma (Hela) and human urinary bladder (T24) cell lines which, in some cases, were equal to, or even higher than those of cis-dichlorodiammineplatinum(II) (cisplatin, DDP), the widely clinically used drug. The further in vivo antitumor tests of DBDCT towards the transplantation tumor models of sarcoma carcinoma (S(180)), hepatocellular carcinoma (H(22)) and Ehrlich's ascites carcinoma (EAC) on mice were carried out via injection intraperitoneally with cisplatin as positive contrast drug. The results showed that DBDCT displayed in vivo antitumor activity against the hepatocellular carcinoma H(22) and sarcoma carcinoma S(180) which were close to those of cisplatin, meanwhile, the survival-extending rates at middle dose and high dose on mice Ehrlich's ascites tumor EAC were higher than those of cisplatin, and there was a good dose-effect relationship.

Two new dimeric phenanthrenes, bulbophythrins A (1) and B (2), were isolated from Bulbophyllum odoratissimum. Their structures were elucidated by HR-ESI-MS, 1D and 2DNMR spectroscopy. They were evaluated in vitro for their inhibitory ability against the growth of human leukemia cell lines K562 and HL-60, human lung adenocarcinoma A549, human hepatoma BEL-7402 and human stomach cancer SGC-7901. Both compounds showed significant cytotoxicity against the tested cell lines. Compound 1 exhibited some selectivity against HL-60 and BEL-7402 with IC(50) values of 1.27 x 10(-3) and 1.22 x 10(-3) micromol/ml respectively, whereas 2 was most active against A549 with IC(50) value of 1.18 x 10(-3) micromol/ml.

Complexes of copper (II) with hesperetin, naringenin, and apigenin of general composition [CuL(2)(H(2)O)(2)] nH(2)O (1-3) have been synthesized and characterized by elemental analysis, UV-Vis, FT-IR, ESI-MS, and TG-DTG thermal analysis. The free ligands and the metal complexes have been tested in vitro against human cancer cell lines hepatocellular carcinoma (HepG-2), gastric carcinomas (SGC-7901), and cervical carcinoma (HeLa). Complexes 1 and 3 were found to exhibit growth inhibition of SGC-7901 and HepG2 cell lines with respect to the free ligands; the inhibitory rate of complex 1 is 43.2% and 43.8%, while complex 3 is 46% and 36%, respectively. The interactions of complex 1 and its ligand Hsp with calf thymus DNA were investigated by UV-Vis, fluorescence, and CD spectra. Both complex 1 and Hsp were found to bind DNA in intercalation modes, and the binding affinity of complex 1 was stronger than that of free ligand.

A new cytotoxic roridin-type trichothecene macrolide named roritoxin E(1) was characterized from the solid culture of Myrothecium roridum IFB-E091 (residing originally inside Artemisia annua root), together with the known compounds lumichrome (2), (22 E,24 S)-cerevisterol (3), and (22 E,24 R)-6 beta-methoxy-ergosta-7,22-diene-3 beta,5 alpha-diol (4). The structure of the new macrolide (1) was elucidated by a combination of spectroscopic (UV, IR, MS, and 1D and 2D NMR) analyses. Compound 1 was demonstrated to be inhibitory in vitro against the gastric carcinoma SGC-7901 and hepatocarcinoma SMMC-7721 cell lines, with IC (50) values of 0.26 and 10.54 microg/mL, respectively. 5-Fluorouracil co-assayed as a positive control had an IC (50) value of 6.66 microg/mL against SGC-7901 cells, and it demonstrated only a 9.98 % growth inhibition against SMMC-7721 cells at 10 microg/mL.

Two new isoprenylated flavonoids, artotonins A and B (1 and 2), along with 13 known compounds (3-15), were isolated from the roots of Artocarpus tonkinensis A. Chev. ex Gagnep. The structures were elucidated by spectroscopic methods. Cyclocommunol (6), isocyclomulberrin (7), cudraflavone C (11), and morusin (13) exhibited cytotoxicity against hepatocellular carcinoma (SMMC-7721) and gastric carcinoma (BGC-823 and SGC-7901) cell lines.

Two novel alkaloids, saprosmine A (1) and saprosmine B (2), were isolated from the stem of Saprosma hainanense MERR., along with five known alkaloids: marcanine A (3); cleistopholine (4); 4-methoxycarbonyl-5,10-benzogquinolinequinone (5); liriodenine (6); and quinoline (7). The chemical structures were established on the basis of extensive spectroscopic (IR, 1D-NMR, 2D-NMR, MS) data analysis and by comparison with spectroscopic data reported in the literature. Compounds 1 to 6 were evaluated for in vitro cytotoxic activities against the SPC-A-1 (human lung cancer), BEL-7402 (human hepatocellular carcinoma), SGC-7901 (human gastric cancer), and K-562 (human myelogenous leukaemia) cancer cell lines. Compounds 1 and 2 exhibited weak cytotoxic activities against K-562 cells. Compounds 3 and 5 showed cytotoxic activities against all four cancer cell lines.

Bioassay-guided fractionation of the ethanolic extract from the seeds of Antiaris toxicaria led to the isolation of three new cardiac glycosides named toxicarioside J, toxicarioside K, and toxicarioside L, together with a known glucostrophalloside. The structures of the new compounds were elucidated by spectroscopic methods including HRESIMS, UV, IR, and 1D, 2D NMR techniques. The cytotoxic activities of these cardiac glycosides against human gastric (SGC-7901) and human hepatoma (SMMC-7721) cell lines were evaluated, and all of them exhibited significant cytotoxicity.
