Khoom piav qhia
2, 3-dimercaptosuccinic acid (DMSA), tseem hu ua 2, 3-dimercaptosuccinic acid, yog cov organic sulfur compound, dawb crystalline hmoov nyob rau hauv chav tsev kub. Vim hais tias cov molecule muaj ob pawg sulfhydryl, nws muaj cov yam ntxwv tsw ntawm sulfhydryl tebchaw. Ob qho tib si dimercaptosuccinic acid thiab nws cov ntsev ntsev tuaj yeem siv los ua cov tshuaj tua kab mob los kho mob hnyav hlau lom. Dimercaptosuccinic acid muaj ob lub diastereoisomers, ib qho yog meso thiab lwm yam yog racemic. Racemes tuaj yeem siv los ua cov tshuaj chelates, thiab cov ntsev sodium feem ntau siv.
Succimer yog siv rau hauv kev kho mob ntawm cov kab mob ua rau mob hnyav kom tshem tawm cov hlau lead ntau dhau ntawm lub cev, tshwj xeeb tshaj yog rau cov menyuam yaus. Sucimer ua ke nrog cov hlau lead hauv cov hlab ntsha. Kev sib xyaw ua ke ntawm cov hlau lead thiab succimer yog tom qab ntawd tshem tawm ntawm lub cev los ntawm lub raum.
DMSA kuj yog ib qho tshuaj tiv thaiv kab mob ua rau muaj tshuaj lom, tshwj xeeb tshaj yog rau cov menyuam yaus vim tias nws tsis muaj tshuaj lom ntau dua li DMPS. Meso-DMSA muaj ntau qhov zoo dua li lwm cov chelators, xws li cov tshuaj lom neeg tsawg, tsis muaj kev faib tawm ntawm cov hlau los ntawm ib lub cev mus rau lwm qhov.

Yuav ua li cas yog lub mechanism ntawm kev txiav txim ntawm succimer?
Succimer yog ib qho hnyav hlau chelator. Nws khi nrog qhov tshwj xeeb siab rau ions ntawm cov hlau lead hauv cov ntshav los tsim cov dej-soluble complex uas yog tom qab tso tawm los ntawm ob lub raum. Succimer kuj tseem tuaj yeem chelate mercury, cadmium, thiab arsenic li no. Ceev tab sis txawv txav.
DMSA puas siv tau?
Txawm hais tias DMSA muaj txiaj ntsig zoo rau kev kho mob ntawm cov hlau lead intoxication, cov teebmeem tshwm sim tau raug tshaj tawm. Lawv suav nrog kev tsis xis nyob hauv plab, cov tshuaj tiv thaiv ntawm daim tawv nqaij, me me neutropenia, thiab siab siab enzymes.
Puas yog DMSA muaj kev nyab xeeb?
DMSA muaj kev nyab xeeb heev thiab feem ntau zam tau zoo, nrog rau qee qhov kev mob tshwm sim raug sau tseg. Qee cov neeg mob yuav muaj kev cuam tshuam me ntsis ntawm plab hnyuv lossis urticaria, tab sis feem ntau tsis tas yuav tsum txiav kev kho mob. 25Txhua yam kev ua kom tshem tawm cov tshuaj lom kom lub plab zom mov kom ua haujlwm tag nrho.
