Development of anti-acanthamoebic approaches.

Area of Science:

• Ophthalmology
• Microbiology
• Drug Discovery

Background:

• Acanthamoeba keratitis is a serious, sight-threatening infection.
• Increasing contact lens use exacerbates public health concerns.
• Current treatments are challenging and often ineffective against Acanthamoeba.

Purpose of the Study:

• To identify novel compounds with anti-amoebic activity against Acanthamoeba.
• To evaluate the efficacy and safety of potential therapeutic agents.

Main Methods:

• Bioassay-guided screening of various compounds targeting cellulose, ion channels, and biochemical pathways.
• Testing anti-amoebic effects of selected compounds.
• Assessing compound toxicity on human cells.

Main Results:

• Acarbose, indaziflam, terbuthylazine, glimepiride, inositol, vildagliptin, and repaglinide demonstrated significant anti-amoebic effects.
• The identified compounds exhibited low toxicity against human cells.
• These findings suggest potential for developing new treatments.

Conclusions:

• Several tested compounds show promise for treating Acanthamoeba keratitis.
• Future research should explore nanoparticle conjugation for enhanced delivery and efficacy.
• This study provides leads for novel therapeutic interventions against this challenging infection.
