Evaluation of amlodipine against strains of spp. in planktonic cells, developing biofilms and mature biofilms.

To evaluate the antifungal activity of amlodipine against strains of spp. and to its possible mechanism of action. Broth microdilution tests were used to determine the minimum inhibitory concentration, while the synergistic activity was evaluated by calculating the fractional inhibitory concentration index.

Analysis of the anti-Candida activity of tricyclic antidepressants in association with amphotericin B and their antifungal mechanisms.

Candida species are among the priority pathogens in the area of research and development. Due to the problems associated with resistance to antifungals, new therapeutic alternatives are necessary. In this regard, drug repositioning has gained prominence.

Antifungal activity of propafenone on spp. strains: interaction with antifungals and possible mechanism of action.

The development of new antifungal drugs has become a global priority, given the increasing cases of fungal diseases together with the rising resistance to available antifungal drugs. In this scenario, drug repositioning has emerged as an alternative for such development, with advantages such as reduced research time and costs. Propafenone is an antiarrhythmic drug whose antifungal activity is poorly described, being a good candidate for further study.

Synergistic activity of diclofenac sodium with oxacillin against planktonic cells and biofilm of methicillin-resistant strains.

To evaluate the activity of diclofenac sodium and synergism with oxacillin against clinical strains of SARM in plactonic cells, antibiofilm and biofilm. Synergism activity was assessed using the fractional inhibitory concentration index and its possible mechanism of action by flow cytometry. The synergistic activity of diclofenac sodium with oxacillin was observed against plactonic cells, antibiofilm and in biofilm formed from clinical methicillin-resistant strains.

Etomidate inhibits the growth of MRSA and exhibits synergism with oxacillin.

The purpose of this study was to evaluate the antimicrobial activity of the anesthetic etomidate against strains of MRSA and biofilms. The antibacterial effect of etomidate was assessed by the broth microdilution method. To investigate the probable action mechanism of the compound flow cytometry techniques were used.
