Ingabe usemakethe yempuphu ye-RU58841 futhi uzibuza ukuthi uzoyitholaphi? Ukuthenga impuphu ye-RU58841 ngqo efektri kunikeza izinzuzo eziningi, okuhlanganisa ukuqinisekiswa kwekhwalithi, ukusebenza kahle kwezindleko, izinketho zokwenza ngokwezifiso, ukwesekwa kobuchwepheshe, ukulawulwa kochungechunge lokuhlinzeka kanye nokucaca. Ngokusungula ubuhlobo obuqondile nomenzi, ungathola impuphu ye-RU58841 esezingeni eliphezulu ehlangabezana nezidingo zakho ezithile ngenkathi wenza ngcono izindleko kanye nokusebenza kahle. Uma ucabanga ukuthenga impuphu ye-RU58841, cabanga ngezinzuzo zokuthola ngqo efektri ukuze wandise inani kanye nokusebenza komkhiqizo wakho.
RU58841, eyaziwa nangokuthi i-PSK-3841 noma i-HMR-3841, iyi-antiandrogen engeyona i-steroidal. Le nhlanganisela yasungulwa ngawo-1990 futhi izifundo zakuqala zelebhu zabonisa amandla ayo okwelapha i-androgenic alopecia, noma i-pattern baldness. . Ngokungafani nezindlela eziningi zokwelapha, ivimbela ukuncipha kwezinwele ngokusebenza endaweni ekhanda ngaphandle kwemiphumela emibi yesistimu. Isebenza ngokuvimbela imiphumela ye-dihydrotestosterone (DHT), i-hormone eyaziwa ngokubangela ukulahlekelwa izinwele kokubili kwabesilisa nabesifazane. Ngokuvimbela imiphumela ye-DHT kuma-follicle ezinwele, i-RU58841 yenzelwe ukuvimbela ukulahlekelwa izinwele okuqhubekayo futhi okungenzeka ikhuthaze ukukhula kabusha kwezinwele.
Ngaphezu kwalokho, amanye ama-antiandrogen asebenza ngokunciphisa noma ukuvimba ukwenziwa kwe-dihydrotestosterone (DHT). Indlela yokusebenza kwe-RU58841 ihluke ngokuphelele kwamanye ama-antiandrogen. Nasi isizathu:
I-RU58841 ibopha ngokuncintisana kuma-receptor e-DHT. Ngakho-ke, empeleni ivimbela i-DHT ekunamatheleni kuma-receptor. Ayinciphisi ukukhiqizwa kwe-DHT. Ngakho-ke, imiphumela emibi yesistimu ngenxa yokukhiqizwa kwe-DHT okuncishisiwe, njengemiphumela emibi yezocansi, ayiveli.
Njenge-finasteride (kodwa ngaphandle kwemiphumela emibi), i-RU58841 isebenza kanje:
●Ivimbela isenzo sokusindisa se-DHT (dihydrotestosterone)
●Yandisa iphesenti lezinwele ze-anagen
●Kuthuthukisa ukuqina kwezinwele nobubanzi bazo
Isetshenziswa phezulu, okusho ukuthi isebenza kuphela lapho isetshenziswa khona futhi cishe ayinakuba nemiphumela ebanzi.
I-Finasteride umuthi kadokotela osetshenziswa kakhulu ekwelapheni impandla yabesilisa (i-androgenic alopecia) kanye ne-benign prostatic hyperplasia (BPH). Umuthi ophuzwa kanye ngosuku. I-Finasteride yavunyelwa yi-US Food and Drug Administration (FDA) ngo-1997 ukwelapha impandla yabesilisa.
Kusukela lapho isetshenziswe kabanzi futhi yacwaningwa kahle, kanye nobufakazi obuningi bezokwelapha obusekela ukusebenza kwayo.
Lo muthi ungowesigaba semithi ebizwa ngokuthi ama-5-alpha-reductase inhibitors.
I-Finasteride isebenza ngokuvimbela i-5-alpha-reductase, i-enzyme ebangela ukuguqula i-testosterone ibe yi-dihydrotestosterone (DHT). Ngokuvimba lokhu kuguqulwa, i-finasteride yehlisa amazinga e-dihydrotestosterone (DHT), i-hormone ebalulekile ehilelekile ekunciphiseni izinwele zekhanda.
Lo mphumela ungasiza ekunciphiseni ukulahleka kwezinwele futhi, kwezinye izimo, kukhuthaze ukukhula kabusha kwezinwele kwabesilisa abane-androgenic alopecia noma impandla yephethini yabesilisa.
I-RU58841 kanye ne-finasteride zombili ziyimithi yokwelapha ukulahleka kwezinwele, kodwa ziyahlukahluka ngezindlela zazo zokusebenzisa, izindlela zokusebenza, kanye nesimo sokulawula.
Imiyalelo
I-RU58841 iyisisombululo sokwelapha isikhumba, okusho ukuthi ingafakwa ngqo esikhumbeni sezinwele. Lokhu kwelashwa ngokwelapha isikhumba kusiza ekuqedeni izinwele ngqo emsukeni. I-Finasteride, ngakolunye uhlangothi, umuthi ophuzwa ngomlomo futhi onemiphumela emihle emzimbeni.
Indlela yokusebenza
I-RU58841 isebenza ngokuvimba i-DHT ezingeni le-receptor yesikhumba, iyivimbele ekubangeleni ukulahleka kwezinwele, ngaphandle kokuthinta kakhulu amazinga e-DHT kwezinye izingxenye zomzimba. Kodwa-ke, i-finasteride isebenza ngokuvimbela i-5-alpha-reductase, i-enzyme ebhekene nokuguqula i-testosterone ibe yi-DHT, ngaleyo ndlela yehlise amazinga e-DHT kuwo wonke umzimba.
Isimo sokulawula
I-Finasteride ivunyelwe yi-FDA ukwelapha impandla yabesilisa futhi ifundwe kabanzi ezivivinyweni zemitholampilo. I-RU58841 ayivunywanga yi-FDA futhi ayifundwanga kabanzi, ngakho-ke kuncane okwaziwayo ngemiphumela yayo engaba khona yesikhathi eside kanye nokuphepha.
I-RU58841 vs. I-Finasteride: Yimuphi Okufanele?
I-Finasteride iyindlela yokwelapha ukulahleka kwezinwele eqinisekisiwe, evunyelwe yi-FDA. Ihlolwe ngokucophelela ezivivinyweni zemitholampilo, inikeza ukuqonda okugcwele kokusebenza kwayo kanye nemiphumela emibi engaba khona. Ngakolunye uhlangothi, i-RU58841 iyintsha ethembisayo endaweni yokwelapha ukulahleka kwezinwele. Isetshenziswa ngaphandle, ihlose ukulahleka kwezinwele ngqo emnyombweni futhi inikeza enye indlela kulabo abangathandi imithi yomlomo.
Ucwaningo lwasekuqaleni lusikisela ukuthi lungaba usizo kakhulu ekukhuthazeni ukukhula kwezinwele ngaphandle kokubangela imiphumela emibi ohlelweni.
Okokuqala, ake sibheke ukukhiqizwainqubo ye-RU58841. Le nhlanganisela iyi-antiandrogen engeyona i-steroidal, okusho ukuthi isebenza ngokuvimbela imiphumela ye-androgens efana ne-DHT kuma-follicle ezinwele. Ukwenziwa kwe-RU58841 kuhilela ukusabela kwamakhemikhali amaningi kanye nezinqubo. Ngokuvamile kukhiqizwa ngamasu e-organic chemistry, kuqala ngokukhethwa kwezinto ezithile zamakhemikhali kanye nama-reagent. Lezi zinto zokusetshenziswa zithola ukusabela okuhlukahlukene njengokufinyela, ukunciphisa, kanye nokuhlanzwa ukuze kukhiqizwe inhlanganisela yokugcina ye-RU58841.
Ubumsulwa kanye nekhwalithi ye-RU58841 yizinto ezibalulekile ekusebenzeni kwayo kahle ekwelapheni ukulahleka kwezinwele. Abakhiqizi kumele balandele izindinganiso eziqinile kanye nezinqubo ukuqinisekisa ukuthi ama-compounds awanakho ukungcola kanye nokungcola. Lokhu kubalulekile ekugcineni ukusebenza kwayo kahle kanye nokuphepha ekusetshenzisweni kwezinwele.
I-RU58841 isebenza ngokuvimbela imiphumela ye-dihydrotestosterone (DHT), i-hormone ehlotshaniswa ne-androgenic alopecia, noma i-pattern baldness. Isebenza njengomphikisi oncintisanayo we-androgen receptor, okusho ukuthi incintisana ne-DHT ngezindawo ezifanayo zokubopha kuma-follicle ezinwele. Uma i-RU58841 ibopha kula ma-receptor, ivimbela i-DHT ekunamatheleni nasekusebenziseni imiphumela yayo yokunciphisa izinwele, okungenzeka inciphise noma imise ukulahleka kwezinwele.
Kubikwa ukuthi i-RU58841 iyasebenza ezifundweni zokuqala kanye nobufakazi obungacacile, ikakhulukazi ngenxa yendlela yayo yokusebenza eyingqayizivele engaphazamisi ukwenziwa kwe-dihydrotestosterone (DHT) kanye ne-testosterone.
Lo msebenzi wokukhetha uyakhanga ngoba unamandla okuhlinzeka ngezinzuzo zokuvimbela ukulahleka kwezinwele ngaphandle kwemiphumela emibi yesistimu evamile kwezinye izindlela zokwelapha.
Le nhlanganisela isetshenziswa ngaphandle kokusebenzisa i-topical futhi ingakhiwa ibe yisisombululo esifakwe ngaphandle njenge-serum noma i-foam bese ifakwa ngqo esikhumbeni sezinwele. Lokhu kulethwa okuqondiwe kuvumela i-compound ukuthi isebenze ngqo endaweni ye-follicle yezinwele, ikhulise ukusebenza kwayo ngenkathi inciphisa imiphumela emibi yesistimu. Yakhelwe ukuvimba imiphumela ye-DHT ngqo ezingeni lesikhumba sezinwele ngaphandle kokuthinta kakhulu amazinga e-DHT emzimbeni.
Lesi sici siyakhanga kubasebenzisi abaningi ngoba sinciphisa ingozi yemiphumela emibi yomzimba, njengokungasebenzi kahle kocansi, okuvame ukuhlotshaniswa nezithibi ze-DHT zomzimba njenge-finasteride.
