Shanghai Ruifu Chemical Co., Ltd. ndiwopanga komanso ogulitsa (1S,2S)-(+)-2-Amino-1-(4-nitrophenyl)-1,3-propanediol (CAS: 2964-48-9) ) ndi khalidwe lapamwamba, lotchedwanso L-(+)-threo-2-Amino-1- (4-nitrophenyl) -1,3-propanediol.Iwondi wapakatikati wa Chloramphenicol (CAS: 56-75-7).
Chloramphenicol (CAS: 56-75-7), yomwe imadziwikanso kuti chlornitromycin, ndi mankhwala opha tizilombo toyambitsa matenda omwe amachokera ku Streptomyces venezuelae.Poyamba idasiyanitsidwa ndi zikhalidwe za Streptomyces venequelae mu 1947 koma tsopano idapangidwa mopanga.Zopangira zopangidwa ndi racemic, zomwe zimatchedwanso synthomycin.Syntomycin ndi chisakanizo cha chloramphenicol L-isomer ndi d-isomer.Chifukwa cha dextroisomer antibacterial effect, zotsatira za synthomycin ndi theka la zinthu zachilengedwe.Kapangidwe kake kamakhala kosavuta ndipo anali mankhwala oyamba ophatikizika kwambiri omwe anapezeka.Ndiwothandiza polimbana ndi mabakiteriya angapo a gram-positive ndi gram-negative ndipo amagwiritsidwa ntchito pofufuza kaphatikizidwe ka mapuloteni ndikusankha maselo osinthika osamva chloramphenicol kapena jini ya bakiteriya ya CAT.
