En este trabajo examinamos los efectos de PAM quiméricos que contienen el motivo mínimo de LfcinB y BFII en C. albicans (CAAL), C. glabrata (CAGL) y C. auris (CAAU), con la evaluación de la concentración mínima inhibitoria (CMI) y concentración mínima fungicida (CMF), cinética de crecimiento y la combinación de la quimera QC2 con FLU. Nuestros resultados indicaron que las quimeras QC1 y QC2 exhibieron actividad fungistática y fungicida dependiente de la concentración contra Candida spp resistente, mayor actividad en comparación con el motivo mínimo de LfcinB, el palíndromo de BFII y las otras cinco quimeras estudiadas; y un efecto de aditividad con fluconazol contra CAAL256 (resistente a FLU), C. glabrata 2001 y C. auris 001. Estas quimeras pueden ser consideradas promisorias ya que además de presentar actividad antifúngica contra cepas de referencia y aislados clínicos de Candida spp, también se ha reportado que exhiben actividad antibacteriana, tanto en bacterias Gram positivas como Gram negativas(1). Los resultados sugieren que estas quimeras pueden ser de amplio espectro antimicrobiano. (Texto tomado de la fuente)The reduced number of molecules with antifungal activity and the appearance of resistant clinical isolates, such as yeasts of the genus Candida spp., have limited the therapeutic efficacy of antifungal agents in recent years. In this work, we examined the effects of chimeric PAMs containing the minimal motif of LfcinB and BFII in C. albicans (CAAL), C. glabrata (CAGL), and C. auris (CAAU), with the evaluation of minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC), growth kinetics, and combination of QC2 chimera with FLU. Our results indicated that QC1 and QC2 chimeras exhibited concentration-dependent fungistatic and fungicidal activity against resistant Candida spp, higher activity compared to minimal motifs of LfcinB, BFII palindrome and other five chimeras studied, and an additivity effect with fluconazole against CAAL256 (resistant to FLU), C. glabrata 2001 and C. auris 001. In addition to present antifungal activity against reference strains and clinical isolates of Candida spp, they also presented antibacterial activity, both in Gram-positive and Gram-negative bacteria (1). These chimeras show a broad antimicrobial spectrum and can be considered as promising molecules for therapeutic applications.MaestríaMagister en Ciencias--Microbiologíaxii, 93 páginasapplication/pdfspaUniversidad Nacional de ColombiaBogotá - Ciencias - Maestría en Ciencias - MicrobiologíaFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede BogotáPéptidos quiméricos derivados de Lactoferricina Bovina y Buforina II: actividad antifúngica contra aislados clínicos y cepas de referencia de Candida sppChimeric peptides derived from Bovine Lactoferricin and Buforin II: antifungal activity against clinical isolates and reference strains of Candida sppTrabajo de grado - Maestríainfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/acceptedVersionOtherhttp://purl.org/redcol/resource_type/TMPineda-Castañeda HM, Huertas-Ortiz KA, Leal-Castro AL, Vargas-Casanova Y, Parra-Giraldo CM, García-Castañeda JE, et al.
