Ceftofur Hydrochloride (103980-44-5)
Mafotokozedwe Akatundu
Ceftiofur ndi mankhwala amtundu wa cephalosporin (m'badwo wachitatu), wololedwa kugwiritsidwa ntchito pachipatala cha Chowona Zanyama.Idafotokozedwa koyamba mu 1987.
Imagonjetsedwa ndi ma antibiotic resistance enzyme beta-lactamase, ndipo imakhala ndi zochita motsutsana ndi mabakiteriya a gram-positive ndi gram-negative.Mitundu ya E. coli yosamva ceftiofur yanenedwa.
Ceftiofur Hydrochloride ndi mtundu wa mchere wa hydrochloride wa ceftiofur, semisynthetic, beta-lactamase-stable, wide-spectrum, cephalosporin wa m'badwo wachitatu wokhala ndi antibacterial zochita.Ceftiofur amamanga ndi inactivates penicillin-binding mapuloteni (PBPs) amene ali pa nembanemba wa mkati mwa bakiteriya cell khoma.Ma PBP ndi ma enzyme omwe amaphatikizidwa m'magawo omaliza a kusonkhanitsa khoma la cell ya bakiteriya ndikukonzanso khoma la cell panthawi yakukula ndi kugawikana.Kutsegula kwa ma PBP kumasokoneza kulumikizana kwa unyolo wa peptidoglycan kofunikira kuti ma cell a bakiteriya akhale olimba komanso olimba.Izi zimabweretsa kufooka kwa khoma la bakiteriya cell ndikuyambitsa cell lysis.
