Summary
Marine invertebrates, specifically bryozoans, yielded novel brominated compounds. Terminoflustrindole A shows potent antifungal and cytotoxic activity, while related compounds lack antimicrobial effects.
Area of Science:
- Marine biology
- Natural product chemistry
- Pharmacology
Background:
- Marine invertebrates are a rich source of bioactive natural products.
- The phylum Bryozoa remains underexplored for novel compounds with therapeutic potential.
- Previous research has identified compounds with medical applications from bryozoans.
Purpose of the Study:
- To investigate novel brominated metabolites from the bryozoan Terminoflustra membranaceatruncata.
- To analyze the biological activities of these newly identified compounds.
- To elucidate the structures of related dibrominated variants.
Main Methods:
- Isolation and structural elucidation of brominated metabolites.
- Antimicrobial activity assays.
- Cytotoxicity testing against tumor cell lines.
- Liquid chromatography-mass spectrometry (LC-MS) analysis for compound distribution.
Main Results:
- A novel group of brominated metabolites, including terminoflustrindoles A, B, and C, were identified.
- Tribrominated terminoflustrindole A (Cm-1) demonstrated significant antifungal and potent cytotoxic activities against tumor cell lines.
- Dibrominated terminoflustrindoles B and C exhibited no antimicrobial activity in the same assays.
- LC-MS analysis revealed a gradient distribution of terminoflustrindole A within the bryozoan colony.
Conclusions:
- Terminoflustra membranaceatruncata is a source of bioactive brominated compounds.
- Terminoflustrindole A possesses promising antifungal and anticancer properties.
- Structural variations (bromination) significantly impact the biological activity of these metabolites.
- Further research into bryozoan natural products may yield novel therapeutic agents.

02:36Regioselectivity and Stereochemistry of Hydroboration
9.6K
A significant aspect of hydroboration–oxidation is the regio- and stereochemical outcome of the reaction.
Hydroboration proceeds in a concerted fashion with the attack of borane on the π bond, giving a cyclic four-centered transition state. The –BH2 group is bonded to the less substituted carbon and –H to the more substituted carbon. The concerted nature requires the simultaneous addition of –H and –BH2 across the same face of the alkene giving syn stereochemistry.

01:27Radical Substitution: Allylic Bromination
6.8K
In organic synthesis, the formation of products can be altered by changing the reaction conditions. For example, a dibromo addition product is formed when propene is treated with bromine at room temperature. In contrast, propene undergoes allylic substitution in non-polar solvents at high temperatures to give 3-bromopropene. In order to avoid the addition reaction, the bromine concentration must be kept as low as possible throughout the reaction. This can be achieved using N-bromosuccinimide...

02:46Halogenation of Alkenes
20.6K
Halogenation is the addition of chlorine or bromine across the double bond in an alkene to yield a vicinal dihalide. The reaction occurs in the presence of inert and non-nucleophilic solvents, such as methylene chloride, chloroform, or carbon tetrachloride.
Consider the bromination of cyclopentene. Molecular bromine is polarized in the proximity of the π electrons of cyclopentene. An electrophilic bromine atom adds across the double bond, forming a cyclic bromonium ion intermediate.

02:41Formation of Halohydrin from Alkenes
14.9K
An alkene, such as propene, reacts with bromine in the presence of water to yield a halohydrin. Halohydrins contain a halogen and a hydroxyl group attached to adjacent carbons. When the halogen is bromine, it is called a bromohydrin, while a chlorohydrin has chlorine as the halogen.

3.9K
The method to achieve α-brominated carboxylic acids using a mixture of phosphorus tribromide and bromine is known as the Hell–Volhard–Zelinski reaction. The reaction is catalyzed by phosphorus tribromide, which can be used directly or produced in situ from red phosphorus and bromine. The mechanism comprises PBr3 catalyzed conversion of acid to acid bromide and hydrogen bromide. The acid bromide enolizes to its enol form in the presence of HBr. The nucleophilic enol attacks the...

03:08Hydroboration-Oxidation of Alkenes
11.9K
In addition to the oxymercuration–demercuration method, which converts the alkenes to alcohols with Markovnikov orientation, a complementary hydroboration-oxidation method yields the anti-Markovnikov product. The hydroboration reaction, discovered in 1959 by H.C. Brown, involves the addition of a B–H bond of borane to an alkene giving an organoborane intermediate. The oxidation of this intermediate with basic hydrogen peroxide forms an alcohol.
