AI Article Synopsis
- A new triterpenoidal compound called 'amnomopin' was identified from the extract of Petriella setifera and has a complex chemical structure.
- The extract shows significant anti-Candida activity against various Candida species, such as Candida albicans and Candida kefyr, with high effectiveness measured in millimeters of inhibition.
- Both the total extract and amnomopin have low minimum inhibitory concentrations, indicating strong potency, and the oral administration of the extract did not adversely affect liver or kidney functions.
Article Abstract
A novel triterpenoidal compound named 'amnomopin' (3β-diglucoside-5,12-28-oic acid), which is named IUPAC as 3-O-(2' ➔ 1″diglucoside)1,2,3,4,4a,5,6,6a,6b,7,9,10,11,12,12a,12b,13,14b-octadecahydro-10-hydroxy-2,2,6a,6b,9,9,12a-heptamethylpicene-4a-carboxylic acid, was isolated from the extract Petriella setifera. The total alcoholic extract of P. setifera showed a great activity against clinically isolated Candida species, including Candida albicans, Candida dubliniensis, Candida famata, Candida glabrata, Candida inconspicua, Candida kefyr, Candida krusei, Candida norvegensis, Candida parapsilosis and Candida tropicalis. Also, the new compound amnomopin was active against all the investigated Candida species. The highest anticandidal activity of P. setifera extract was obtained against C. kefyr (22.6 ± 1.5 mm), C. albicans and C. norvegensis (21.3 ± 0.63 mm) and C. krusei (20.6 ± 1.5 mm). Moreover, the minimum inhibitory concentrations of both the total extract and the isolated compound were low. The minimum inhibitory concentration of the compound isolated from P. setifera was 0.49 μg/mL against C. kefyr, 0.98 μg/mL against C. albicans and C. norvegensis and 1.95 μg/mL against C. krusei. The oral dosing of the extract and the isolated compound did not show any significant effect on the activity of alanine aminotransferase, aspirate aminotransferase and the levels of blood urea and serum creatinine.

Background: Vulvovaginal candidiasis (VVC), caused primarily by Candida albicans, is currently treated with either prescription or over-the-counter antifungal drugs, often with variable efficacy and relapses. New and improved therapeutic strategies, including drug-free treatment alternatives, are needed. Upon overgrowth or environmental triggers, C.

This response has been implicated in controlling the invasive form of the fungus and maintaining the yeast as an innocuous commensal. However, the specific targets of this response are still unknown.
