Taupānga:

Ko Shanghai Ruifu Chemical Co., Ltd. te kaihanga matua me te kaiwhakarato o (1S,2S)-(+)-2-Amino-1-(4-nitrophenyl)-1,3-propanediol (CAS: 2964-48-9 ) me te kounga teitei, ko L-(+)-threo-2-Amino-1-(4-nitrophenyl)-1,3-propanediol.Kohe takawaenga o Chloramphenicol (CAS: 56-75-7).

Ko te Chloramphenicol (CAS: 56-75-7), e mohiotia ana ko te chlornitromycin, he momo paturopi huakita bacteriostatic i ahu mai i Streptomyces venezuelae.I wehe tuatahi mai i nga ahurea o Streptomyces venequelae i te tau 1947 engari inaianei ka hangaia ma te waihanga.Ko te hua waihanga he racemic, e kiia ana ko te synthomycin.Ko te Syntomycin he ranunga o te chloramphenicol L-isomer me te d-isomer.Na te paanga antibacterial dextroisomer, ko te hua o te synthomycin he haurua noa o nga hua taiao.He ahua ngawari noa tona hanganga, a ko te paturopi whaanui tuatahi i kitea.He whai hua ki te maha o nga huakita karamu-pai me te karamu-kino, me te whakamahia nuitia ki te rangahau i te whakahiato pūmua me te whiriwhiri mo nga pūtau huri-atete-chloramphenicol, te ira CAT huakita ranei.
