This product has a strong cytotoxic effect in vitro and has a significant anti-tumor effect on a variety of transplanted tumors in vivo. It is first converted into 5-fluoro-2-deoxyuridine by enzymes in the body, which inhibits thymidine synthetase and blocks the conversion of deoxyuridine nucleotides into deoxythymidine nucleotides, thereby inhibiting the biosynthesis of DNA. In addition, it can also be incorporated into RNA, and inhibit RNA synthesis by preventing uracil and orotic acid from incorporating into RNA. This product is a cell cycle-specific drug that mainly inhibits tumor cells in the S phase.

This product is an acetanilide antipyretic analgesic. It inhibits the prostaglandin synthase in the hypothalamic temperature regulation center, reduces the synthesis and release of prostaglandin PGE1, causes peripheral vasodilation and sweating, and achieves an antipyretic effect. Its antipyretic effect is similar to that of aspirin; it inhibits the synthesis and release of prostaglandin PGE1, bradykinin and histamine, increases the pain threshold and has an analgesic effect. It is a peripheral analgesic, weaker than aspirin, and is only effective for mild and moderate pain. This product has no obvious anti-inflammatory effect.

Extract from the above information

This product is a broad-spectrum antibacterial agent with bactericidal effect at high concentrations. In addition to common Gram-positive bacteria, Gram-negative bacteria and anaerobic bacteria, most Rickettsia, Mycoplasma, Chlamydia, atypical mycobacteria and spirochetes are also sensitive to this product. This product is better than Gram-positive bacteria for Gram-negative bacteria, but Enterococcus is resistant to it. Others such as Actinomycetes, Bacillus anthracis, Listeria monocytogenes, Clostridium, Nocardia, etc. are sensitive to this product. This product has certain antibacterial activity against Neisseria gonorrhoeae, but penicillin-resistant gonococci are also resistant to tetracycline. This product has good antibacterial effect on Gram-negative bacteria such as Vibrio, Yersinia pestis, Brucella, Campylobacter, Yersinia, etc., has no antibacterial activity against Pseudomonas aeruginosa, and has certain antibacterial effect on some anaerobic bacteria.
