Abstract

Hypertension and obesity are two significant factors that contribute to the onset and exacerbation of a cascade of mechanisms including activation of the sympathetic and renin-angiotensin systems, oxidative stress, release of inflammatory mediators, increase of adipogenesis and thus promotion of systemic dysfunction that leads to clinical manifestations of cardiovascular diseases. Seaweeds, in addition to their use as food, are now unanimously acknowledged as an invaluable source of new natural products that may hold noteworthy leads for future drug discovery and development, including in the prevention and/or treatment of the cardiovascular risk factors. Several compounds including peptides, phlorotannins, polysaccharides, carotenoids, and sterols, isolated from brown, red and green macroalgae exhibit significant anti-hypertensive and anti-obesity properties. This review will provide a comprehensive overview of the recent advances on bioactive pure compounds isolated from different seaweed sources focusing on their potential use as drugs to treat or prevent hypertension and obesity. On the other hand, although it is obvious that macroalgae represent promising sources of antihypertensive and anti-obesity compounds, it is also clear that further efforts are required to fully understand their cellular mechanisms of action, to establish structure-inhibition relationships and mainly to evaluate them in pre-clinical and clinical trials.

  • Seaweed-derived peptides from Undaria pinnatifida, Neopyropia yezoensis, Ulva rigida, and Ulva clathrata have shown ACE inhibitory activity.

    “Among seaweed-derived peptides, species such as Undaria pinnatifida (Phaeophyceae), Neopyropia yezoensis (formerly Porphyra yezoensis) (Rhodophyta), Ulva rigida, and Ulva clathrata (formerly Enteromorpha clathrata) have shown ACE inhibitory activity [53–57].”

    From Navigating the potential of algal peptides: health effects, market applications, and scientific challenges (2026) · cites this paper as [54]

    Section 2.1 reports ACE I-inhibitory peptides from Undaria pinnatifida, Porphyra yezoensis (listed there as Pyropia yezoensis), and Ulva rigida. It also reports an inhibitory peptide attributed to Enteromorpha clathrata, but explicitly says that seaweed was not properly identified and only notes a suggested equivalence between Enteromorpha and Ulva. The source therefore does not firmly establish the claim for Ulva clathrata. (LLM, conf=0.85)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
