Thiamphenicol 15318-45-3 Antibiotic Powder Pharmaceutical Raw Material
Methamphenicol is a broad-spectrum chloramphenicol antibiotic, which has a stronger effect on Gram-negative bacteria than that on positive ones. Under normal temperature, it is white to almost white crystalline powder or crystal, which can be absorbed rapidly and completely by oral administration. In terms of metabolism, it is mainly excreted from urine in prototype. Clinically, it is mainly used for the treatment of respiratory, urinary, hepatobiliary, typhoid and other intestinal surgery, gynecology and obstetrics, and facial infections, especially for mild and moderate infections. Its chemical structure is similar to that of chloramphenicol. Its methylsulfone group replaces the nitro group of chloramphenicol, so its toxicity is 2.5-5 times higher than that of chloramphenicol. It has a strong antibacterial effect on Gram-positive bacteria such as pneumococcus and hemolytic streptococcus. It also has a strong antibacterial effect on Gram-positive bacteria such as gonococcus, meningococci, pulmonary bacilli, Escherichia coli, Vibrio cholerae, dysentery bacteria and influenza bacteria. It also has a certain antibacterial effect on anaerobic bacilli, Rickettsia, amoeba, etc. Its mechanism of action and chloromyces Same element. It is mainly to inhibit the synthesis of bacterial protein. The drug can be absorbed rapidly by oral administration, and the blood concentration can reach the peak within 2 hours, with a half-life of 5 hours, which is longer than chloramphenicol. The bacteria have complete cross resistance between the product and chloramphenicol, and partial cross resistance between the product and tetracycline.
Methamphenicol also has strong immunosuppressive effect and is an excellent immunosuppressant. Its mechanism of action is significantly different from other immunosuppressive agents, and its immunosuppressive effect is several times higher than that of chloramphenicol. To reflect the effective prolongation of transplantation and surgical homograft
Thiamphenicol (also known as thiophenicol and dextrosulphenidol) is an antibiotic. It is the methyl-sulfonyl analogue of chloramphenicol and has a similar spectrum of activity, but is 2.5 to 5 times as potent. Like chloramphenicol, it is insoluble in water, but highly soluble in lipids. It is used in many countries as a veterinary antibiotic, but is available in China and Italy for use in humans. Its main advantage over chloramphenicol is that it has never been associated with aplastic anaemia.
Thiamphenicol is also widely used in Brazil, particularly for the treatment of sexually transmitted infections and pelvic inflammatory disease.
Unlike chloramphenicol, thiamphenicol is is not readily metabolized in cattle, poultry, sheep, or humans, but is predominantly excreted unchanged. In pigs and rats the drug is excreted both as parent drug and as thiamphenicol glucuronate.
