Summary
Nine new ent-kaurane diterpenoids were isolated from Isodon parvifolius leaves. These compounds, along with known analogues, were tested for anticancer activity against A549, HT-29, and K562 cell lines.
Area of Science:
- Natural Products Chemistry
- Organic Chemistry
- Pharmacology
Background:
- Isodon parvifolius is a plant source of bioactive compounds.
- Diterpenoids are a class of natural products with diverse biological activities.
Purpose of the Study:
- To isolate and characterize new ent-kaurane diterpenoids from Isodon parvifolius.
- To evaluate the cytotoxic potential of isolated compounds against cancer cell lines.
Main Methods:
- Isolation of compounds using chromatographic techniques.
- Structure elucidation of new compounds via spectroscopic methods (1D and 2D NMR).
- In vitro evaluation of inhibitory activity against A549, HT-29, and K562 cell lines.
Main Results:
- Nine new 7alpha,20-epoxy-ent-kaurane diterpenoids, named parvifolines C-K (1-9), were identified.
- Twelve known diterpenoids were co-isolated.
- Compounds 1-9 and lasiodonin (12) exhibited varying degrees of inhibitory activity against the tested cancer cell lines.

02:36Crown Ethers
Crown ethers are cyclic polyethers that contain multiple oxygen atoms, usually arranged in a regular pattern. The first crown ether was synthesized by Charles Pederson while working at DuPont in 1967. For this work, Pedersen was co-awarded the 1987 Nobel Prize in Chemistry. Crown ethers are named using the formula x-crown-y, where x is the total number of atoms in the ring and y is the number of ether oxygen atoms. The term 'crown' refers to the crown-like shape that these ether molecules take.

Carboxylic acid derivatives are formed by replacing the hydroxyl group of carboxylic acids with a different functional group. The most common carboxylic acid derivatives are:
03:00Preparation of Epoxides
Overview
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of peroxy acids to...

02:26Base-Catalyzed Ring-Opening of Epoxides
Due to their highly strained structures, epoxides can readily undergo ring-opening reactions through nucleophilic substitution, either in the presence of an acid or a base. The nucleophilic substitution reactions in the presence of acid are called acid-catalyzed ring-opening reactions, and nucleophilic substitution reactions in the presence of a base are called base-catalyzed ring-opening reactions. Epoxides undergo base-catalyzed ring-opening reactions in the presence of a strong nucleophile...
02:38Structure and Nomenclature of Epoxides
Cyclic ethers are heterocyclic compounds with an oxygen atom in the ring along with carbon atoms. They are named depending on the number of carbon atoms present in their ring system. Cyclic ethers with a three-membered ring system are called “oxirane”, four-membered ring systems as “oxetane”, five-membered ring systems as “oxolane”, and six-membered ring systems as “oxane”. The cyclic structure of these rings imposes angle strain, and this strain is more in the ring having a smaller number of...
02:24Acid-Catalyzed Ring-Opening of Epoxides
Epoxides that are three-membered ring systems are more reactive than other cyclic and acyclic ethers. The high reactivity of epoxides originates from the strain present in the ring. This ring strain acts as a driving force for epoxides to undergo ring-opening reactions either with halogen acids or weak nucleophiles in the presence of mild acid. The acid catalyst converts the epoxide oxygen, a poor leaving group, into an oxonium ion, a better leaving group, making the reaction feasible. The...
