It has a broad-spectrum antimicrobial effect in vitro, including aerobic Gram-negative and Gram-positive bacteria, anaerobes, Rickettsia, spirochetes and Chlamydia. It has a bactericidal effect on Haemophilus influenzae, Streptococcus pneumoniae and Neisseria meningitidis; it only has an antibacterial effect on anaerobic bacteria such as Staphylococcus aureus, Streptococcus pyogenes, Streptococcus viridans, Group B hemolytic Streptococcus, Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Salmonella typhi, Salmonella paratyphi, Shigella, Bacteroides fragilis, etc. Pseudomonas aeruginosa, Acinetobacter, Enterobacter, Serratia marcescens, indole-positive Proteus, methicillin-resistant Staphylococcus and Enterococcus are usually resistant to chloramphenicol. Chloramphenicol is fat-soluble, enters bacterial cells by diffusion, and reversibly binds to the 50S subunit of bacterial ribosomes, inhibiting the formation of peptide chains, thereby preventing protein synthesis.

Mycophenolate mofetil (MMF) is a 2-ethyl ester derivative of mycophenolic acid (MPA). MPA is a highly effective, selective, non-competitive, and reversible inhibitor of inosine mononucleotide dehydrogenase (IMPDH) and can inhibit the classical synthesis pathway of guanine nucleotides. MPA has a highly selective effect on lymphocytes. Mycophenolate mofetil tablets are extremely effective in preventing rejection reactions after renal transplantation and treating refractory rejection.

Restores the imbalance between the excitation and inhibition processes of the cerebral cortex, and has central inhibitory effects such as sedation, hypnosis and analgesia

Antibacterial drug. It is relatively stable against the β-lactamase produced by Staphylococcus aureus, so it has a strong antibacterial effect against Gram-positive bacteria; it is unstable against the β-lactamase produced by Gram-negative bacteria, so it has a weaker effect against Gram-negative bacteria, and is ineffective against Pseudomonas aeruginosa and anaerobic bacteria.
