I-S)-(+)-Camptothecin CAS:7689-03-4

(S) -(+)-I-Camptothecin inesithembiso ekwelapheni izinhlobo ezahlukene zomdlavuza, ikakhulukazi emkhakheni we-chemotherapy. Indlela esebenza ngayo ihilela ukuqondisa nokuvimbela umsebenzi we-topoisomerase I, i-enzyme ebalulekile ekukhululeni i-DNA ngesikhathi sokuhlukaniswa kwamaseli. Ngokuphazamisa le nqubo, i-(S)-(+)-I-Camptothecin ivimbela amaseli omdlavuza ukuthi aphindaphindeke futhi ande, ekugcineni okubangela i-apoptosis noma ukufa kwamaseli okuhleliwe. Le khompawundi ibonise ukusebenza kahle ngokumelene nezinhlobo eziningana zomdlavuza, okuhlanganisa umdlavuza wamaphaphu we-colorectal, we-ovarian, kanye noweseli elincane, phakathi kwezinye. Imizamo yocwaningo igxile ekwakheni ama-derivatives kanye nokwakheka kwe-(S)-(+)-I-Camptothecin ukuze kuthuthukiswe ukuncibilika kwayo kanye nokutholakala kwayo, kuthuthukiswe ukusetshenziswa kwayo kwezokwelapha. Izifundo zemitholampilo kanye nokuhlolwa kuhlole ukusetshenziswa kwe-(S)-(+)-I-Camptothecin njenge-ejenti eyodwa noma kuhlanganiswe nezinye izidakamizwa zokwelapha ngamakhemikhali ukuze kukhuliswe imiphumela yayo yokulwa nomdlavuza ngenkathi kunciphisa ukusabela okubi. Kodwa-ke, kubalulekile ukuqaphela ukuthi i-(S)-(+)-Camptothecin ingabonisa ubuthi nemiphumela emibi, okudinga ukuqapha nokuphathwa ngokucophelela ochwepheshe bezempilo. Ukuhlolwa kwe-(S)-(+)-Camptothecin kanye nemikhiqizo yayo kuyaqhubeka nokuqhubekisela phambili intuthuko ekwelashweni komdlavuza, okunikeza ithemba lemiphumela yokwelapha ethuthukisiwe kanye nekhwalithi yokuphila kweziguli ezilwa nomdlavuza ohlukahlukene.
