This product is a dipeptide compound isolated from the culture fluid of Streptomyces of ivoreticuli, which can competitively inhibit aminopeptidase B and leucine peptidase. It can enhance the function of T cells, enhance the killing activity of NK cells, and increase the synthesis of colony stimulating factors to stimulate the regeneration and differentiation of bone marrow cells. This product can interfere with the metabolism of tumor cells, inhibit tumor cell proliferation, cause tumor cell apoptosis, activate human cellular immune function, stimulate the production and secretion of cytokines, and promote the production and proliferation of anti-tumor effector cells.

Antihistamines with selective peripheral H1 receptor antagonism, inhibiting the release of histamine from peritoneal mast cells, without anticholinergic, α1-adrenergic or β-adrenergic receptor blocking effects, without sedation or other central nervous system effects, and cannot cross the blood-brain barrier

Gatifloxacin is a racemic compound of 8-methoxyfluoroquinolone, which has a broad spectrum of activity against Gram-negative and Gram-positive microorganisms in vitro. Its R- and S-enantiomers have the same antibacterial activity. The antibacterial effect of this product is through inhibiting bacterial DNA gyrase and topoisomerase IV, thereby inhibiting bacterial DNA replication, transcription and repair processes. It has antibacterial activity against most strains of the following microorganisms: 1 Gram-positive bacteria: Staphylococcus aureus (limited to strains sensitive to methicillin), Streptococcus pneumoniae (strains sensitive to penicillin). 2 Gram-negative bacteria: Escherichia coli, Haemophilus influenzae and parainfluenzae, Klebsiella pneumoniae, Moraxella catarrhalis, Neisseria gonorrhoeae, Proteus mirabilis. 3 Other microorganisms: Chlamydia pneumoniae, Legionella pneumophila, Mycoplasma pneumoniae.
