Antifungal Agents

Antifungal Agents

Amphotericin B is a broad-spectrum antifungal agent that exploits structural differences between fungal and mammalian cell membranes. Its amphipathic structure—featuring a hydrophobic polyene-lactone ring and a hydrophilic region containing mycosamine and carboxylic acid groups—enables selective binding to ergosterol, a sterol predominantly found in fungal plasma membranes. This selective interaction underlies the drug’s antifungal activity, although weak binding to cholesterol contributes to...

Defenses Against Pathogens and Herbivores

Defenses Against Pathogens and Herbivores

Plants present a rich source of nutrients for many organisms, making it a target for herbivores and infectious agents. Plants, though lacking a proper immune system, have developed an array of constitutive and inducible defenses to fend off these attacks.

C4 Pathway and CAM

C4 Pathway and CAM

Most plants use the C3 pathway for carbon fixation. However, some plants, such as sugar cane, corn, and cacti that grow in hot conditions, use alternative pathways to fix carbon and conserve energy loss due to photorespiration. Photorespiration is the process that occurs when the oxygen concentration is high. Under such conditions, the rubisco enzyme in the Calvin cycle binds O2 instead of CO2, which halts photosynthesis and consumes energy.

The C4 pathway is used by plants such as...

Area of Science:

Natural Product Chemistry
Pharmacology
Medicinal Plant Research

Background:

Cichorium intybus L. (chicory) is a plant with a history of medicinal use.
Phytochemical investigations aim to identify bioactive compounds from medicinal plants.

Purpose of the Study:

To isolate and characterize chemical constituents from Cichorium intybus L.
To evaluate the cytotoxic activity of isolated compounds against the A2780 cell line.

Main Methods:

Isolation of compounds using chromatographic techniques.
Structure elucidation employing 1D and 2D Nuclear Magnetic Resonance (NMR) spectroscopy and mass spectrometry.
In vitro cytotoxic activity assay against the A2780 ovarian cancer cell line.

Main Results:

A new sesquiterpenoid (1) and four known compounds (lactucin (2), 1beta-hydroxy-eudesmolide (3), 13,14-seco-stigma-dien-ol (4), and bacosterol glucoside (5)) were isolated.
Lactucin (2) exhibited an IC50 value of 1.81 microM against A2780 cells.
13,14-seco-stigma-dien-ol (4) displayed potent activity with an IC50 value of 0.07 microM against A2780 cells.

Conclusions:

Cichorium intybus L. is a source of diverse phytochemicals, including novel sesquiterpenoids.
Compounds lactucin and 13,14-seco-stigma-dien-ol possess significant cytotoxic potential against the A2780 cell line, warranting further investigation for anticancer drug development.
