Candidiasis

Candidiasis

Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...

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...

Area of Science:

Ethnobotany
Pharmacology
Phytochemistry

Background:

Ocimum gratissimum, a tropical plant, is recognized in folk medicine for various applications.
Research has identified five distinct chemotypes of Ocimum gratissimum essential oils.
Traditional uses suggest potential therapeutic benefits, warranting scientific investigation.

Purpose of the Study:

To investigate the antifungal properties of Ocimum gratissimum essential oil.
To characterize the chemical composition of a specific Indian chemotype.
To evaluate the in vitro efficacy of ethyl cinnamate-rich Ocimum gratissimum oil.

Main Methods:

Essential oil extraction from Ocimum gratissimum.
Gas chromatography-mass spectrometry (GC-MS) for chemotype analysis.
In vitro antifungal assays to determine efficacy.

Main Results:

Five distinct chemotypes of Ocimum gratissimum essential oil were identified.
An Indian chemotype was found to be particularly rich in ethyl cinnamate.
This specific chemotype exhibited a notable spectrum of in vitro antifungal activity.

Conclusions:

Ocimum gratissimum possesses significant antifungal potential.
The Indian chemotype, high in ethyl cinnamate, is a promising source for antifungal agents.
Further research into Ocimum gratissimum could lead to new antifungal therapies.
