Antiviral activity of diterpenes isolated from the Brazilian marine alga Dictyota menstrualis against human immunodeficiency virus type 1 (HIV-1).
The effects of the diterpenes isolated from the Brazilian brown algae Dictyota pfaffii and Dictyota menstrualis against the herpes simplex type-1 replicative cycle.
TLDR
The results suggest that the structures of compounds 1 and 2, Brazilian brown algae diterpenes, might be promising for future antiviral design, suggesting that these compounds inhibit initial events during HSV-1 replication.
Potential cytotoxic activity of some Brazilian seaweeds on human melanoma cells
In vitro screening of the crude extracts of some Brazilian coastal seaweeds for cytotoxic activity against a cultured human melanoma cancer cell line using the sulphorhodamine B assay was performed.…
A VANADIUM BROMOPEROXIDASE CATALYZES THE FORMATION OF HIGH‐MOLECULAR‐WEIGHT COMPLEXES BETWEEN BROWN ALGAL PHENOLIC SUBSTANCES AND ALGINATES 1
TLDR
It is proposed that VBPO promotes the binding of PS molecules to the ALG uronic acids residues, and it is suggested that PS are components of the brown algal cell walls.
Caulerpin as a potential antiviral drug against herpes simplex virus type 1
TLDR
It is shown that caulerpin could be an alternative to acyclovir as an anti-HSV-1 drug that inhibits the alpha and beta phases of the replication cycle.
The dolabellane diterpene Dolabelladienetriol is a typical noncompetitive inhibitor of HIV-1 reverse transcriptase enzyme.
Ecological roles of natural products of the Brazilian red seaweed Laurencia obtusa.
TLDR
Direct protection against two herbivore species and indirect protection against herbivory by fouling inibition constitute evidence that the major natural product from Brazilian L. obtusa plays multiple environmental roles, thereby increasing the adaptive value of these metabolites.
Dolabelladienetriol, a Compound from Dictyota pfaffii Algae, Inhibits the Infection by Leishmania amazonensis
TLDR
Dolabelladienetriol significantly inhibits Leishmania in macrophages even in the presence of factors that exacerbate parasite growth, such as IL-10, TGF-β and HIV-1 co-infection.
