AB  - This study aimed to screen in vitro antitumour activity of the redox couple avarol/avarone against the human malignant glioma cell line U-251 MG for the first time. Compared both with avarol and positive controls used (temozolomide and doxorubicin), avarone was found to be the most active compound with IC50 value below 1 mu M (IC50 0.68 +/- 0.04 mu M, 96 h). Considerable less DNA damage in the cells treated with avarol and avarone vs. doxorubicin (105 & 123% vs. 299%, respectively; untreated U-251 MG cells were used as a control, 100%), coupled with no sign of cytotoxicity against the normal human foetal lung fibroblast MRC-5 cells (IC50 > 100 mu M), has actually pointed out the importance of this marine sesquiterpenoid quinone structure as a promising lead compound in development of novel brain chemotherapeutics.

AB  - The growth inhibition of stictic acid, a secondary metabolite isolated from the lichen Lobaria pulmonaria (L.) Hoffm. (Lobariaceae), was evaluated in vitro on three human cell lines for the first time. The cell lines HT-29 and MCF-7 were utilized for measuring the activity of stictic acid against cancer cells, while the cell line MRC-5 was selected for estimation of its effect on normal cells. The results suggest a moderate anticancer activity (IC50 value for the cell line HT-29 was 29.29 mu g/ml) and a low growth inhibition on nonmalignant cells (IC50 value for the cell line MRC-5 was 2478.40 mu g/ml) of stictic acid. This natural product can be considered as a promising lead compound for the design of novel human colon adenocarcinoma drugs.

AB  - The cytotoxicity of avarol, a main secondary metabolite of the Mediterranean sponge Dysidea avara, was in vitro screened by MTT assay against four human tumour cell lines. The colon HT-29 tumour cells practically showed to be the only sensitive ones towards this organic compound. No toxicity was found against the fetal lung fibroblast MRC-5 cells at the concentrations tested. In comparison with doxorubicin, used as a positive control, avarol actually exhibited at least 588-fold less toxicity towards normal MRC-5 cells. Finally, comet assay indicated that DNA fragmentation was almost fivefold higher upon the treatment with doxorubicin, compared to avarol. The obtained results have actually confirmed that avarol scaffold may contribute to development of new cytostatics inspired by nature.

Its anticandidial activity was evaluated by microdilution method against eight Candida strains, two ATCC and six clinical ones. At a different extent this compound was proven to be active against all the strains tested (MIC 0.8-6.0g/mL and MFC 1.6-12.0g/mL, respectively). According to the best of our knowledge, this is the first report on avarol activity towards any yeast strain which may be of relevance for Alzheimer's disease. Indeed, avarol derivatives showing moderate AChE activity should be screened for anticandidial activity both in vitro and in vivo. [GRAPHICS] .

The compound tested induced dose-dependent cytotoxic response in all cancer cells showing better activity towards the lung A-549 and colon HT-29 cell lines (IC50 7.40M and 9.62M, respectively) than towards the breast adenocarcinoma ER positive MCF-7 and ER negative MDA-MB-231 cells (IC50 11.64M and 17.31M, respectively), the prostate adenocarcinoma PC-3 and epiteloid cervix carcinoma HeLa cells (IC50 14.24M and 15.54M, respectively). No toxicity was found towards the foetal lung fibroblast MRC-5 cell line at the concentrations used. According to experimental data obtained, the sesquiterpenoid quinone structure of avarone may inspire development of new drug-like substances with improved cytotoxicity on lung cancer in humans.

The IC50 values towards the other five tumours (HeLa, HT-29, A-549, Hs294T and MDA-MB-231) ranged from 15.51 to 69.67 mu M. However, mild toxicity was detected against the foetal lung fibroblast MRC-5 cells at the concentrations used (IC50 124.84 +/- 1.59 mu M). According to the experimental data obtained, this cost-effective natural product widely present in the biosphere may inspire the development of new drug-like substances with improved cytotoxic activity on breast cancer.

AB  - The immunomodulatory and anticarcinogenic activity of the freshwater bryozoan Hyalinella punctata methanolic extract (MEx) was evaluated in vitro on selected biosystems for the first time. Murine lymphocytes and macrophages were used for testing of MEx effects on cell proliferation and nitric oxide (NO) production, respectively, while human cancer cell lines were utilized for measuring its activity against cancer cells. The results suggest a strong and tissue-specific immunomodifying activity (IC50 values for inhibition of proliferation of lymph node and spleen-derived lymphocytes were 4.1 mu g/ml and 9.7 mu g/ml, respectively) and moderate anticancer activity of MEx (IC50 value for the MCF-7 cell line was 24.13 mu g/ml). Down-regulation of macrophage NO production was also obtained. The potential use of H. punctata-derived natural products for the treatment of human chronic inflammatory diseases and cancer is worthy of further investigation.

abstract = "The immunomodulatory and anticarcinogenic activity of the freshwater bryozoan Hyalinella punctata methanolic extract (MEx) was evaluated in vitro on selected biosystems for the first time. Murine lymphocytes and macrophages were used for testing of MEx effects on cell proliferation and nitric oxide (NO) production, respectively, while human cancer cell lines were utilized for measuring its activity against cancer cells. The results suggest a strong and tissue-specific immunomodifying activity (IC50 values for inhibition of proliferation of lymph node and spleen-derived lymphocytes were 4.1 mu g/ml and 9.7 mu g/ml, respectively) and moderate anticancer activity of MEx (IC50 value for the MCF-7 cell line was 24.13 mu g/ml). Down-regulation of macrophage NO production was also obtained. The potential use of H. punctata-derived natural products for the treatment of human chronic inflammatory diseases and cancer is worthy of further investigation.",
