RESUMEN
Due to the excessive and inappropriate use of antibiotics in farming and clinic, pathogens developed resistance mechanisms to currently used drugs. Thus, because of this resistance, drugs become ineffective, leading to public health problems worldwide. According to the World Health Organization (WHO), microbial resistance to drugs is one of the most threats that humanity must face. Therefore, it is imperative to seek alternative methods to overcome microbial resistance. Here, the potential of natural or synthetic antimicrobial peptides to overcome microbial resistance will be discussed, and how peptides could be a source for new therapeutics molecules. In this context, antimicrobial peptides (natural or synthetic) are considered promising molecules based on their antifungal, antiviral, and antibacterial properties, making them eligible for developing new drugs. In addition, they can act synergistically with existing drugs on the market, revealing a broad spectrum of applications.
