Abstract

The ceragenins, designed to mimic the activities of antimicrobial peptides, are a new class of antimicrobial agent. In this study, in vitro antif ungal activities of the novel cationic steroid molecules CSA-8, CSA-13, CSA-44, CSA-131 and CSA-138, were assessed against Candida albicans strains isolated f rom blood cultures. MICs and MBCs were determined by microdilu- tion technique according to CLSI guidelines. Susceptibility testing demonstrated that the MICs were ranging 0.125-128 µg/ ml. The MIC50 values of CSA-8, CSA-13, CSA-44, CSA-131 and CSA-138 were 0.5 µg/ml, 1 µg/ml, 1 µg/ml, 2 µg/ml and 8 µg/ml, respectively. The MFCs were equal to or two-f old greater than those of the MICs. According to our results, cationic steroid antibiotics especially, CSA-131 and CSA-138 appear to be good candidates in the treatment of C.albicans inf ections. Future studies should be perf ormed to correlate its saf ety, eff icacy and pharmacoki- netic parameters of these molecules.

Özet

Cerageninler, antimikrobiyal peptitlere benzer aktivite gösteren, yeni bir grup katyonik steroid antimikrobiyal molekül- lerdir. Bu çalışmada kan kültürlerinden izole edilmiş Candida albicans suşlarına karşı katyonik steroid antibiyotiklerden olan CSA-8, CSA-13, CSA-44, CSA-131 ve CSA-138in in vitro antif ungal duyarlılıklarının belirlenmesi amaçlanmıştır. MİK ve MBK değerleri CLSI kurallarına uygun olarak mikrodilüsyon yöntemi ile belirlenmiştir. Duyarlılık test sonuçlarına göre MİK değerleri 0.125-128 µg/ml arasında değişmektedir. CSA-8, CSA-13, CSA-44, CSA-131 ve CSA-138 için MİK50 değerleri sırasıyla 0.5 µg/ml, 1 µg/ml, 1 µg/ml, 2 µg/ml ve 8 µg/mldir. MFK değerleri ise MİK değerlerine eşit yada iki katıdır. Çalışmamızın sonuçlarına göre, CSA-131 ve CSA-138 C.albicans inf eksiyonlarının tedavisinde kullanılabilecek iyi birer aday moleküldür. İleriki çalışmalarda bu moleküllerin güvenilirlik, etkinlik ve f armakokinetik parametrelerinin belirlen- mesi gerekmektedir.
