5-Amino-1-(2-Hydroxyethyl)pyrazole (CAS: 73616-27-0) is an intermediates of Cefoselis (CAS: 122841-10-5) & Cefoselis Sulfate (CAS: 122841-12-7). Cefoselis is a new fourth-generation cephalosporin and was launched in Japan as a parenteral antibiotic for a variety of infections including Staphylococcus aureus (particularly the methicillin-resistant MRSA) and Pseudornonas aeruginosa. It can be prepared in 3 related ways, all using 2- pyrazolomethyl-3-cephem-4-carboxylic as the key intermediate. In preclinical studies, Cefolesis had better MIC50s than Ceftazidime against Streptococcus pneurnoniae or Staphflococcus aureus (methicillin-sensitive MSSA or resistant MRSA) and showed significant antibacterial activity against Citrobacter and Enterobacter. Cefolesis is well tolerated in clinical studies, being eliminated mainly via glomerular filtration in humans.
