Chemotherapeutic properties of the new cephalosporin antibiotic HR810 in laboratory animals.
The chemotherapeutic properties of the new aminothiazolyl cephalosporin HR810 were investigated in experimental animals. Unlike other cephalosporins of the third generation, HR810 had good activity against Staphylococcus aureus as well as some activity against enterococci. In murine protection tests with these strains, it was clearly superior to ceftazidime, cefotaxime, ceftriaxone, cefoperazone and latamoxef. The compounds most effective in protecting mice from infections caused by Enterobacteriaceae were HR810 and ceftriaxone followed by ceftazidime, latamoxef and cefotaxime; cefoperazone was less active. HR810 was less active against Pseudomonas aeruginosa than ceftazidime but was considerably more effective than the other cephalosporins tested. HR810 also proved effective against localised infections such as thigh lesions, as well as against meningo-encephalitis in mice and pyelonephritis in rats. These results in laboratory animals make HR810 a promising candidate for clinical studies.
