SPR720 disodium is an orally active and potent phosphate VXc-486 prodrug,has potent bactericidal activities in vivo.

Linopristin is a streptogramin B class antibiotic. It is one of the components of the antibiotic combination NXL103.

Psicofuranine: a nucleoside antibiotic inhibiting GMP synthase and P. falciparum growth with an IC50 of 0.3 mM.

PD-L1/LpxC-IN-1 (Compound 12b) is an inhibitor of PD-L1 and LpxC, with IC50 values of 5.2 μM and 0.081 μM, respectively. This compound disrupts bacterial lipopolysaccharide biosynthesis, leading to bacterial cell lysis and death. It effectively inhibits Gram-negative bacteria, exhibiting a minimum inhibitory concentration (MIC) of 0.25-0.5 μg/mL against K. pneumoniae ATCC 13883, E. coli ATCC 8739, S. typhimurium ATCC 14028, and P. aeruginosa ATCC 9027. Additionally, PD-L1/LpxC-IN-1 modulates the immune response by downregulating the expression of inflammatory cytokines IL-2 and IFN-γ, and upregulating CD4+ and CD8+ cells, thus activating the immune system and mitigating excessive inflammatory responses. In a mouse model of K. pneumoniae ATCC 13883 infection, PD-L1/LpxC-IN-1 demonstrated antibacterial activity.

Antimicrobial agent-40 exhibits antibacterial activity against fungi, Gram-negative, and Gram-positive bacteria. It also shows anticancer properties, displaying significant cytotoxicity towards MCF-7 cells with an IC50 of 33.52 μM.

<p>Arylomycin B1 is a lipid hexapeptide antibiotic (antibiotic) effective against Gram-positive bacteria.</p>
