In addition, the proposed compounds derived from intermediates show high urinary excretion, high blood levels, prolonged blood levels and high integral blood levels depending on the duration of action compared with oral cephalosporins, such as cefuroxime (UK) , SCE 21 Ik (Japan) and T-2588 and CS-807 (Japan). Compounds derived from intermediates show an excellent in vivo i of 2.88 mg / kg compared with T-2588 (10.8 mg / kg) and CS-807 (7.8 mg / kg), which is a significant advantage of the proposed compounds in comparison with the known. Biological testing of new cephalosporin antibiotics obtained from the proposed compounds by removing the protective amino groups in the thiazole ring. Male rats weighing 20-25 g are abundantly fed with an aqueous solution of kQ% glucose and vitamins for one day instead of a diet. The next day, the rats were orally administered a suspension of amoxicillin (compounds for comparison) or one of the esters (test compounds) in an aqueous 5% emergency gum with a concentration of 2 mg / ml, the dose administered is 0 mg / kg for each compound used either as a reference or as a test. Then every 15 minutes, blood is taken for analysis to determine plasma activity. The determination is carried out by planting on aha pe, Escherichia coli is used for esters, and for amoxicillin, Micrococcus luteus. The test results are shown in Table. 2 The proposed compounds in the tested doses show no signs of toxicity and belong to the category of low-toxic compounds. Thus, the proposed compounds are intermediate compounds that allow to synthesize new antibiotics of the cephalosporin series, possessing an improved antibacterial .5 activity and injected oralrial but.
