The methanol extract of an assemblage of Halimeda stuposa and a Dictyota sp., yielded three natural products characteristic of Dictyota sp., and one of Halimeda sp. These included the xenicane diterpene 4-hydroxydictyolactone (1), and the diterpenes dictyol E (2), 8α,11-dihydroxypachydictyol A (3) and indole-3-carboxaldehyde (4). A minor revision of 1 and new spectroscopic data for 1 and 2 are provided, along with associated anti-cancer activities of compounds 1–4.

Pachydictyols B and C: New Diterpenes from Dictyota dichotoma Hudson
Two new diterpenoids, pachydictyol B and C, were isolated from the dichloromethane extract of the marine brown alga, Dictyota dichotoma, collected from the Red Sea coast of Egypt and demonstrated a weak and unselective cytotoxicity against twelve human tumor cell lines with a mean IC50 of >30.0 µM.
Anti-microfouling properties of compounds isolated from several Mediterranean Dictyota spp.
Brown algae of the genus Dictyota are widespread around the world and are common along the coasts of the Mediterranean Sea and are known for their ability to produce a wide array of bioactive compounds, mostly diterpenes, whose ecological functions are not clearly defined.
Theoretical Study on the Structures, Spectral Properties, and Drugability of Xenicane-type Diterpenoids from Dictyota dichotoma
T here are few reports on the relationship between the biological activity and structure of secondary metabolites from Dictyota dichotoma . In this work, the geometric and electronic structures,
Terpenoids with Special Pharmacological Significance: A Review
The tricyclic sesquiterpene (–)-englerin A isolated from the stem bark of the Phyllanthus engleri plant (Euphorbiaceae) is highly active against certain renal cancer cell lines, and recent studies showed that engler in A is also a potent and selective activator of TRPC4 and TRPC5 calcium channels.
Enzymatic hydrolysis and ion exchange fractionation of sulfated polysaccharides extracted from Ulva lactuca and evaluation of their biological activity.
All my colleagues and friends were very cooperative and the study wouldn’t be successful without their support.

Anticancer agents derived from marine algae
The present review consolidates the available information on marine algae-derived anticancer principles and their possible mode of action and concludes that marine algae, which are rich in phytochemicals and show a wide species diversity, are a promising source.
Apoptosis-like cell death upon kinetoplastid induction by compounds isolated from the brown algae Dictyota spiralis
Three isolated diterpenes could inhibit the tested parasites by inducing an apoptosis-like cell death in the kinetoplastid, demonstrating the mechanism of action of these compounds on parasitic cells.


New nine-membered ring diterpenes from the brown alga Dictyota prolificans
Five new diterpenes, related to 'dictyodial' (7), have been isolated from the brown alga Dictyota prolificans. The gross structures and, where possible, stereochemistry were solved by spectral
Cytotoxic Hydroazulene Diterpenes from the Brown Alga Cystoseira myrica
Cytotoxicity-guided fractionation of the alcohol extract of the brown alga, Cystoseira myrica, afforded four new cytotoxic hydroazulene diterpenes, dictyone acetate, isodictytriol monoacetate, and cystoseirol monoacetates, which were determined on the basis of spectroscopic and chemical evidence.
Structures and conformations of new nine-membered ring diterpenoids from the marine alga Dictyota dichotoma.
New nine-membered ring diterpenes acetyldictyolal (2), hydroxyacetyldictyolal (4) isodictyohemiacetal (5) and dictyodiacetal (7) have been isolated. Their structures and approximate conformations
Hydroxydictyodial, an antifeedant diterpene and a key intermediate in the biogenesis of several related diterpenes, has been isolated from the brown alga Dictyota spinulosa, and its structure was
