Action mechanism
Cov txheej txheem ntawm kev ua ntawm polycidin yog qhov tshiab thiab tshwj xeeb, uas txawv ntawm cov macrolides dav dav, thiab nws cov qauv tshuaj tshwj xeeb txiav txim siab nws cov tshuaj tua kab tshwj xeeb. Polycidin muaj kev sib cuag sai thiab noj tshuaj lom rau kab. Nws muaj cov tsos mob tshwj xeeb ntawm cov paj hlwb. Nws cov txheej txheem ntawm kev ua haujlwm yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws nws nws cov txheej txheem nws, nws yog ib qho tsim nyog yuav tsum ua kom lub paj hlwb ntawm cov kab tsuag, ua kom nws cov kev ua haujlwm tsis tu ncua, thiab ua rau cov leeg tsis ua haujlwm, tsis ua haujlwm, nrog rau kev co thiab tuag tes tuag taw. Nws tau pom tias nicotinic acetylcholine receptor (nChR) tau ua haujlwm tsis tu ncua los ua kom lub sijhawm ntev acetylcholine (Ach) tso tawm. Polycidin kuj ua rau γ-aminobutyric acid (GAGB) receptors, hloov pauv txoj haujlwm ntawm GABA gated chlorine raws thiab ntxiv dag zog rau nws cov tshuaj tua kab.
Txoj kev degradation
Cov residue ntawm cov tshuaj tua kab nyob rau hauv ib puag ncig yog hais txog "qhov siab tshaj plaws" ntawm cov tshuaj tua kab uas ib puag ncig yuav muaj, uas yog, nyob rau hauv ib cheeb tsam thiab ib lub sij hawm, ob qho tib si los xyuas kom meej cov roj ntsha zoo thiab cov txiaj ntsig ntawm cov khoom ua liaj ua teb thiab tsis ua rau tawg. ib puag ncig zoo. "Maximum load" kuj yog tus nqi pib los ntsuas qhov kev nyab xeeb ntawm ib puag ncig ntawm cov tshuaj tua kab, thiab nws kuj yog qhov sib txawv uas maj mam txo nrog kev hloov ntawm lub sijhawm thiab ib puag ncig. Tsuav nws tsis tshaj qhov pib no, ib puag ncig kev nyab xeeb ntawm cov tshuaj tua kab yog tsim nyog. Polycidin sai degrades nyob rau hauv ib puag ncig los ntawm ntau yam kev sib xyaw ua ke, feem ntau yog photodegradation thiab microbial degradation, thiab thaum kawg decomposes rau hauv tej yam ntuj tso xws li carbon, hydrogen, oxygen, thiab nitrogen, yog li tsis muaj kuab paug rau ib puag ncig. Lub photodegradation ib nrab-lub neej ntawm polycidin hauv av yog 9 ~ 10 hnub, nplooj nplooj yog 1.6 ~ 16 hnub, thiab cov dej tsawg dua 1 hnub. Yog lawm, ib nrab-lub neej muaj feem xyuam nrog kev siv ntawm lub teeb, thaum tsis muaj lub teeb, ib nrab-lub neej ntawm multicidin los ntawm aerobic av metabolism yog 9 mus rau 17 hnub. Tsis tas li ntawd, cov av loj hloov pauv coefficient ntawm polycidin yog nruab nrab K (5 ~ 323), nws solubility hauv dej yog tsawg heev thiab tuaj yeem degraded sai, yog li cov leaching kev ua tau zoo ntawm polycidin yog tsawg heev, yog li nws tsuas yog siv rationally, thiab nws tseem muaj kev nyab xeeb rau cov dej hauv av.
