Antifungal agents are drugs used to treat fungal infections. Depending on their mechanism of action and chemical structure, antifungal agents can be categorized into several classes. Here are some of the main classes and examples of antifungal agents:
- Fluconazole: A triazole antifungal mainly used for the treatment and prevention of superficial and systemic fungal infections.
- Ketoconazole: An imidazole antifungal used to treat a wide variety of fungal infections, though its oral use has become less common due to potential side effects. It’s still frequently used topically.
- Climbazole: An imidazole antifungal primarily used in hair care products to treat dandruff.
- Clotrimazole: An imidazole antifungal used to treat various fungal infections including vaginal yeast infections, oral thrush, and ringworm.
- Itraconazole: A triazole antifungal used primarily to treat a variety of systemic fungal infections.
- Terbinafine: This compound belongs to the allylamine class. It’s mainly used to treat fungal infections of the nails and skin, like athlete’s foot and ringworm.
- Econazole: An imidazole antifungal used mainly for skin infections such as athlete’s foot and ringworm.
- Miconazole: An imidazole antifungal with a broad spectrum of activity. It’s used for a variety of skin infections and also as a vaginal cream for yeast infections.
- Triclosan: This is a broad-spectrum antimicrobial agent. While it has some antifungal activity, it’s more commonly known for its antibacterial properties. Due to concerns regarding its safety and potential contribution to antibiotic resistance, its use in hand soaps and some other personal care products has been phased out in several regions.
Of these, fluconazole, itraconazole, ketoconazole, climbazole, clotrimazole, econazole, and miconazole belong to the azole class, which primarily acts by inhibiting the fungal enzyme lanosterol 14α-demethylase. This enzyme is crucial for ergosterol synthesis, a vital component of fungal cell membranes. Terbinafine, on the other hand, inhibits squalene epoxidase, another enzyme important in ergosterol synthesis. Triclosan works through a different mechanism, targeting bacterial and fungal fatty acid synthesis.
Antifungal Agents can be separated, retained, and analyzed on a Primesep B mix mode phase column using an gradient analytical method with a simple mobile phase of water, Acetonitrile (MeCN), and sulfuric acid as a buffer. This analysis method can be detected in the UV 200 nm.

HPLC Method for Analysis of Fluconazole on Primesep B Column

HPLC Method for Analysis of Fluconazole on Primesep B by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Fluconazole
Fluconazole is an antifungal medication used to treat and prevent various fungal infections. Here are some key points about fluconazole:
1. Mechanism of Action:
- Fluconazole belongs to a class of drugs known as triazole antifungals. It works by inhibiting a fungal enzyme crucial for producing ergosterol, a key component of the fungal cell membrane. Without ergosterol, the fungal cell membrane becomes leaky and the fungal cells die, leading to the clearance of the infection.
2. Indications (Uses):
- Candidiasis: Fluconazole is often prescribed for vaginal yeast infections, which are caused by the fungus Candida. It’s also used for oropharyngeal candidiasis (thrush), systemic candidiasis, and other Candida infections.
- Cryptococcal Meningitis: This is a serious fungal infection of the brain and spinal column, commonly seen in individuals with HIV/AIDS. Fluconazole can be used for treatment and to prevent a recurrence.
- Prophylaxis: In certain at-risk populations, like those with weakened immune systems or patients undergoing bone marrow transplants, fluconazole can be given to prevent fungal infections.
Fluconazole can be retained, and analyzed on a Primesep B mixed-mode stationary phase column using an isocratic analytical method with a simple mobile phase of water, Acetonitrile (MeCN), and a ammonium format a buffer. This analysis method can be detected in the UV 270 nm.
