Pothomorphe umbellata: Antifungal activity against strains of Trichophyton rubrum
Trichophyton rubrum is a dermatophyte, which can cause infections in human skin, hair and nail. Pothomorphe umbellata (L.) Miq. (Piperaceae) is a native Brazilian plant, in which phytochemical studies have demonstrated the presence of steroids, 4-nerolidylcatechol, sesquiterpenes and essential oils....

description | Trichophyton rubrum is a dermatophyte, which can cause infections in human skin, hair and nail. Pothomorphe umbellata (L.) Miq. (Piperaceae) is a native Brazilian plant, in which phytochemical studies have demonstrated the presence of steroids, 4-nerolidylcatechol, sesquiterpenes and essential oils. The objective of this study was to analyze the in vitro activity of extracts and fractions of P. umbellata on resistant strains of T. rubrum. The microdilution plate method was utilized to test Tr1, H6 and ΔTruMDR2 strains of T. rubrum; ΔTruMDR2 strain was obtained from H6 by TruMDR2 gene rupture, which is involved in multiple drugs resistance. The highest antifungal activity to all strains was observed for dichloromethane and hexane fractions of the 70% ethanolic extract which showed minimal inhibitory concentration (MIC) and minimal fungicide concentration (MFC) of 78.13μg/mL. This antifungal activity was also obtained by 70% ethanolic extract, which presented MIC and MFC of 78.13μg/mL to ΔTruMDR2, whereas the MIC values for Tr1 and H6 were 78.13 and 156.25μg/mL, respectively. Our results suggest the potential for future development of new antifungal drugs from P. umbellata, especially to strains presenting multiple resistance.
Trichophyton rubrum est un dermatophyte qui peut provoquer des infections de la peau humaine, des cheveux et des ongles. Pothomorphe umbellata (L.) Miq. (Piperaceae) est une plante originaire du Brésil où les études phytochimiques ont démontré la présence de stéroïdes, de 4-nerolidylcatechol, de sesquiterpènes et d’huiles essentielles. L’objectif de cette étude est analyser l’activité in vitro d’extraits et de fractions de P. umbellata sur les souches de T. rubrum. La méthode de plaque de microdiluition a été utilisée pour faire les essais sur les souches Tr1, H6 et ΔTruMDR2 de T. rubrum ; la souche ΔTruMDR2 a été obtenue à partir de H6 par la délétion du gène TruMDR2, qui est impliqué dans la résistance aux multiples médicaments. La plus forte activité antifongique pour toutes les souches a été observée pour les fractions dichlorométhane et hexane de l’extrait éthanolique 70 % qui ont présenté une concentration minimale inhibitrice (CMI) et une concentration minimale fongicide (CMF) de 78,13μg/mL. Cette activité antifongique a été aussi obtenue pour l’extract éthanolique à 70 %, qui a présenté CMI et CMF de 78,13μg/mL pour la souche ΔTruMDR2, tandis que les valeurs de CMI pour Tr1 et H6 ont été 78,13 et 156,25μg/mL respectivement.
