antibacterial activitiesagainst laboratory and clinically isolated Gram-positive bacteria, including vancomycin-resistantEnterococcus faecium and methicillin-resistant Staphylococcus aureus. We further expanded its antibacterial spectrum into against Gram-negative bacteria with the assistance of polymyxin B nonapeptide, which helps haloemodin to penetrate through the bacterial outer membrane.

The invention generally relates to emodin derivatives of general structure (I), to pharmaceutical compositions comprising same and to their uses in medicine, especially in the treatment of bacterial or viral infections. The invention further relates to textiles, such as fabrics, comprising at least one emodin derivative of general structure (I). R1- R2- R3and R4are independently selected from the group consisting of hydrogen, halogen, NO2, SO3H and COOR; R is H, C1-6-alkyl, C2-6alkenyl or C2-6alkynyl; with the proviso that at least one of R1, R2, R3and R4is not hydrogen.
Antiviral Activities of Halogenated Emodin Derivatives against Human Coronavirus NL63
improve its antiviral activity. The most active compound in this study was the iodinated emodin analogue E_3I, whose anti-HCoV-NL63 activity was comparable to that of remdesivir. Evaluation of the emodin analogues also revealed some unwanted toxicity to Vero cells. Since new synthetic routes are now available that allow modification of the emodin structure, it is reasonable to expect that analogues with
