Widespread but variable toxicity in scleractinian corals
1Department of Zoology, University of Queensland, St Lucia, Brisbane, Australia.
Summary
Coral extracts from the Great Barrier Reef show significant bioactivity. Most species tested exhibited toxicity to mice, cytolysis, or antibacterial properties, highlighting their potential medicinal value.
Area of Science:
- Marine Biology
- Pharmacology
- Biochemistry
Background:
- Scleractinian corals are a diverse group of marine invertebrates.
- Coral reef ecosystems harbor a vast array of bioactive compounds.
- Previous research has indicated potential medicinal properties of coral extracts.
Purpose of the Study:
- To investigate the bioactivity of extracts from scleractinian corals.
- To identify novel bioactive compounds from coral species.
- To explore the potential pharmacological applications of coral extracts.
Main Methods:
- Aqueous and aqueous ethanol extracts were prepared from 58 scleractinian coral species.
- Extracts were tested against various bioassay systems, including toxicity to mice, cytolysis of red blood cells, and antibacterial activity.
- Generalized Linear Interactive Modelling (GLIM) was used to analyze variable results.
Main Results:
- 91% of coral species tested exhibited bioactivity in at least one assay.
- Extracts from 41 species were toxic to mice, 49 showed cytolytic activity, and 37 had antibacterial properties.
- This study reports novel bioactivity for 46 coral species and five coral families.
Conclusions:
- Coral extracts possess significant and diverse bioactivities.
- Antimicrobial activity is influenced by collection timing and coral reproductive status.
- Environmental factors like temperature may affect coral extract toxicity.

161.6K
OverviewElements are the smallest units of matter that cannot be broken down further by chemical processes. There are 118 known elements, but not all of these are naturally-occurring, and fewer still are essential for life. Living matter is composed primarily of carbon, nitrogen, hydrogen, and oxygen, with smaller amounts of other elements like calcium, phosphorus, potassium, and sulfur. Other elements are also necessary for life but only in trace amounts.The Periodic Table Provides Information...

01:26Toxic Reactions: Overview
4.2K
When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

295
Drug toxicity quantifies the harm a compound causes to an organism, varying by dose and potentially impacting whole systems or specific organs like the liver. Toxic reactions may arise from venomous insect or spider bites, with effects ranging from mild symptoms to severe outcomes such as brain damage or death. Common forms of acute poisoning include ethanol intoxication and overdose of pain or fever medications, with substances like GHB and heroin being particularly lethal at doses close to...

01:24Drug Toxicity: Dose-Dependent Reactions
229
Drug toxicities can be stratified into pharmacological, pathological, or genotoxic based on their mechanisms. The incidence and severity of these toxicities generally increase with the drug's concentration in the body and exposure time.Pharmacological toxicity is evident when the therapeutic effects of drugs overshoot into adverse reactions in a predictable, dose-dependent manner. Central nervous system (CNS) depression from barbiturates is a classic example, with effects escalating from...

01:23Toxicity Testing in Animals
204
Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...
