D-(+)-Cycloserine (CAS: 68-41-7) e malosi lona natura hygroscopic, e soluble i le vai, soluble i lalo ifo alcohols, acetone ma dioxane, ma e faigata ona soluble i chloroform ma suauu eter.E fai si mautu i vaifofo alkaline ma e vave ona pala i vaifofo oona po'o le le tutusa.I le avea ai o se vailaʻau faʻamaʻi lautele, o le cycloserine e faʻalavelave i le tele o siama Gram-positive ma Gram-negative, rickettsia ma nisi protozoa, sei vagana ai Mycobacterium tuberculosis., E aoga foi i nisi o Mycobacterium tuberculosis strains ma le faapalepale i streptomycin, vinactane para-aminosalicylic acid, isoniazid ma pyrazinamide.O le cycloserine e fa'afefiloi laititi ma le isoniazid i le taofiofia o le Mycobacterium tuberculosis H37RV, ae e le fa'atasi pe fa'afeagai i le streptomycin.O le oloa o se vaila'au fa'ama'i, ma o le a le fa'aolaina ai le fa'ama'i e tusa lava pe fa'atuputeleina le fua po'o le fa'aumiina o le taimi fa'atino i siama.
O le Mechanism of D-cycloserine's antibacterial action o le taofia lea o le biosynthesis o le peptidoglycan o le puipui sela.Talu ai o se faʻataʻitaʻiga o le D-alanine, e mafai e le D-cycloserine ona faʻatauvaʻa le gaioiga o le alanine racemase ma le D-alanyl-D-alanine synthetase, e lua enzymes taua i le peptidoglycan synthesis.O le D-cycloserine o loʻo faʻaalia ai le vaivai o le faʻalavelave faʻasaga i le Mycobacterium tuberculosis lea e naʻo le 1/10 i le 1/20 o le streptomycin.O le lelei o le oloa e aoga i vailaʻau faʻamaʻi Mycobacterium tuberculosis strains ma faʻaitiitia ai le faʻamalosia o fualaau faʻasaina.O le oloa e mafai ona faʻaaogaina ma isi vailaʻau faʻamaʻi faʻamaʻi i le togafitiga o le mamapala e mafua mai i le Mycobacterium tuberculosis e tetee i vailaʻau.
Cycloserine ose vaila'au fa'ama'i fa'ama'i fa'ama'i laina lona lua.E mafai ona taofia ai le tuputupu aʻe o le Mycobacterium tuberculosis, ae o le aʻafiaga e sili atu le vaivai nai lo fualaau muamua.O lona aoga i togafitiga mamapala e fai si maualalo.Fa'aaoga na'o le vaila'au e mafai ona maua ai le tete'e i vaila'au, ae e tupu malie le tete'e pe a fa'atusatusa i isi vaila'au fa'ama'i mamapala.E leai se fa'afeagai na maua i le va o le cycloserine ma isi vaila'au fa'ama'i mamapala.Ole faiga ole gaioiga ole antibacterial ole fa'alavelaveina ole tu'ufa'atasiga ole peptidoglycan ole puipui sela siama, ma mafua ai le faaletonu ile fausaga puipui puipui.Ole vaega autu ole fausaga ole puipui ole siama ole peptidoglycan, lea e aofia ai le N-acetylglucosamine (GNAc) ma le N-acetylmuramic acid (MNAc).O le N-acetylmuramic acid e fesoʻotaʻi ma le pentapeptide ma faʻafesoʻotaʻi le N-acetylglucosamine i se faiga faʻapipiʻi ma isi auala.O le faʻavaeina o le cytoplasmic peptidoglycan precursor e mafai ona faʻalavelaveina e le cycloserine, ona o le mea mulimuli e mafai ona faʻalavelaveina le racemase ma le synthetase D-Alanine, ma faʻapea ona poloka le faʻavaeina o le N-acetylmuramic acid.

Gaosiga Fa'agasologa:

E mafai ona maua le D-Cycloserine e ala ile faiga fa'apa'u po'o le tu'u sa'o.O le siama o loʻo faʻaaogaina i le faʻafefe o le Actinomyces laven-dulae.O le auala faʻafefete e aofia ai le dextrin, dextrose, starch, paʻu soya, paʻu fefete, ammonium sulfate, ammonium nitrate, calcium carbonate, sodium chloride, magnesium sulfate ma suauu soya.I le faʻagasologa o le faʻasologa, e maua mai le D-Cycloserine mai le β-Aminooxy alanine ethyl ester hydrochloride e ala i le tali atu i le potassium hydroxide i se faʻalavelave faʻafefe.
