                                        Multidrug-resistant (MDR), extensively drug-resistant (XDR), and totally drug-
                                        resistant  bacteria  can  cause  sepsis  and  death  in  patients  due  to  their  ability
                                        to inactivate most antibiotics,  including ampicillin, tetracycline,  streptomycin,
                                        chloramphenicol, erythromycin, and ciprofloxacin.  This paper aims to review
                                        recent advancements in synthetic antibiotics, lantibiotics, and phytoantibiotics
                                        and to present our research on phytoantibiotics, specifically focusing on CU1 and
