≥5mg/ml Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明 Tulathromycin A is a novel long-acting semi-synthetic tribasic macyocyclic antibiotic of the triamilide group and used for the treatment of pulmonary diseases of swine and cattle.
in vitro Tulathromycin A is a macrolide antibiotic that inhibits bacterial protein synthesis (IC50 = 0.26 µM) by targeting the 50S ribosomal subunit, blocking the progression of nascent polypeptide chains[2].
in vivo In cattle and swine, tulathromycin is characterized by a rapid rate of absorption and large systemic availability after subcutaneous (s.c.) and intramuscular (i.m.) administration. In contrast, oral administration of tulathromycin, using a compounded formulation, has a lower systemic availability (~50%). In plasma, tulathromycin has a long terminal half-life, ranging across species from ~2 to ~5 days except in mice in which the terminal half-life is <20 h. The longest terminal half-life in plasma is seen in foals (~140 h). Lung pharmacokinetic studies in cattle, pigs, horses, and mice show that tulathromycin accumulates in lung tissue. In general, tulathromycin is absorbed rapidly and extensively after parenteral administration. Recent published data generated in pigs, cattle and horses show that tulathromycin also accumulates rapidly and extensively in the intra-airway compartment (PELF, BELF, and cells)[1].
