Abstract
INTRODUCTION: Quebrachitol, an optically active cyclitol derived from plants, has attracted interest as a possible natural product inspiration for pharmaceuticals due to its potential medicinal therapeutic qualities in diabetes, cancer, and drug production. However, the antimicrobial properties of quebrachitol were indefinite. This is the first systematic review to specifically determine, appraise, and consolidate the antimicrobial effects of quebrachitol.
METHODS: A comprehensive database search from PubMed, Scopus, and Google Scholar from January 2000 to February 2024 was conducted. All English, full-text, original articles involving experimental, in vivo, or in vitro research were included. Data pertaining to quebrachitol’s effectiveness (nil, partial, or total inhibition) against microorganisms was extracted. In the presence of antimicrobial effects, the minimum effective dosage or duration and mechanism of action were determined. The quality assessments of the articles were performed with QUIN (in vitro) and SYRCLE RoB (in vivo).
RESULTS: The research yielded 866 studies, but only 11 met the inclusion criteria, comprising 7 in vitro, 1 in vivo, 1 in ovo, and 2 papers, which combined both in vitro and in vivo trials. Quebrachitol was found to have an anti-infectious effect against Salmonella sp., Candida albicans, infectious bursal disease virus, Newcastle disease virus, and Plasmodium sp. Additionally, there was significant evidence of inhibitions against biofilm in Staphylococcus epidermidis and methicillin-resistant Staphylococcus aureus (MRSA). QUIN tool revealed that 60% of in vitro studies had a low risk of bias, with overall scores ranging from 56.25 to 87.5%. SYRCLE, however, showed that none of the studies contained more than 50% of the studies exhibited low-risk bias. The allocation sequence demonstrated high-risk bias due to a lack of random sequence generation and reliance on non-random approaches like availability or predetermined rules.
CONCLUSION: Quebrachitol had demonstrated significant and promising antimicrobial potential in the in vitro studies, showing efficacy against pathogens associated with typhoid, malaria, avian flu disease, and biofilm-related diseases. However, the in vivo findings were inconclusive due to high-risk bias. Thus, further well-designed in vivo research is required to establish the antimicrobial efficacy and safety of quebrachitol and to assess its potential role in developing alternative treatments to address current antimicrobial resistance and pharmacovigilance concerns.
