Vinca alkaloids yog muaj peev xwm vesicants [80–82] thiab kev siv tshuaj tsis raug cai tuaj yeem ua rau cov nqaij mos mob hnyav.
YPuas yog vinca alkaloids cytotoxic?
Lawv tau siv los kho ntshav qab zib, ntshav siab thiab tau siv los ua tshuaj tua kab mob thiab tiv thaiv qog noj ntshav. Cov vinca alkaloids muaj cytotoxic teebmeemuas tuaj yeem ntes kev faib cov hlwb thiab ua rau cov cell tuag. Muaj plaub qhov loj vinca alkaloids hauv kev kho mob: VBL, VRL, VCR thiab VDS.
Vinca alkaloids ua dab tsi?
Vinca alkaloids yog siv hauv tshuaj kho mob qog noj ntshav Lawv yog cov chav kawm ntawm lub voj voog ntawm tes-cov tshuaj cytotoxic tshwj xeeb uas ua haujlwm los ntawm inhibiting lub peev xwm ntawm cov qog nqaij hlav qog noj ntshav: Ua raws li tubulin, Lawv tiv thaiv nws los ntawm kev tsim mus rau hauv microtubules, ib qho tseem ceeb tivthaiv rau cellular faib.
Dab tsi yog tshuaj vinca alkaloids?
21.2.
Vinca alkaloids suav nrog vinblastine, vincristine, vindesine, thiab vinorelbinekeeb kwm los ntawm Catharanthus roseus (Apocynaceae). Lawv yog cov paub zoo hauv kev kho mob cytotoxic tshuaj inhibiting lub peev xwm ntawm cov qog nqaij hlav qog nqaij hlav [17].
YPuas yog vinca alkaloids DNA khi?
Kev tshawb fawb Fluorescence ntawm indole alkaloids vinblastine sulfate, vincristine sulfate, vincamine thiab catharanthine tau pom tias DNA khi muaj peev xwm ntawm cov molecules. Kev khi hom ntawm cov molecules hauv qhov me me ntawm DNA tsis yog tshwj xeeb.
Pom zoo:
Qhov twg hauv qab no yog cov tshuaj lom neeg ntawm vinca?
Cov tshuaj lom neeg: Vinca muaj indole alkaloids ntau, feem ntau yog vincristine thiab vinblastine. Vinca kuj muaj lwm cov alkaloids xws li ajmalicine, serpentine thiab lochnerine ua cov tshuaj lom neeg . Dab tsi ntawm vinca yog tshuaj?
Koj puas tuaj yeem hloov vinca?
Vinca minor, tseem hu ua tsawg dua periwinkle thiab creeping myrtle, loj hlob hauv US Department of Agriculture cog hardiness zones 4 txog 10. Lwm thaj chaw ntawm koj lub vaj . Yuav ua li cas khawb vinca? Khawb ib pawg ntawm cov nroj tsuag loj periwinkle, siv ib ntse ntse.
Dab tsi ntawm cov hauv qab no yog cov pob txha ntawm cinchona alkaloids?
Cinchona alkaloids, suav nrog cov neeg uas muaj quinoline skeleton, koom nrog pab pawg no. Quinine thiab quinidine yog siv los ua tshuaj thiab tseem yog cov ntaub ntawv tseem ceeb hauv kev lag luam khoom noj. Cinchonine thiab cinchonidine kuj nquag tshawb xyuas alkaloids .
Cov tshuaj chemo twg yog vesicants?
Vesicants: Cov tshuaj uas tuaj yeem ua rau cov ntaub so ntswg necrosis lossis tsim cov hlwv thaum yuam kev nkag mus rau hauv cov ntaub so ntswg ncig ib leeg [14]. Lawv suav nrog Actinomycin D, Dactinomycin, Daunorubicin, Doxorubicin, Epirubicin, Idarubicin, Mitomycin C, Vinblastine, Vindesine, Vincristine, thiab Vinorelbine YPuas paclitaxel yog vesicant?
Vim li cas thiaj muab cov vesicants ua ntej?
Yog tias yuav tsum tau siv tshuaj ntau ntxiv, cov vesicants yuav tsum tau muab thawj zaug vim cov leeg yuav tsis ua rau lwm tus neeg ua rau khausthiab vim tias tom qab vesicant flushing yuav khaws cov venous integrity (BIII) . Yuav ua li cas koj tswj cov tshuaj vesicant?
