Ukuthuthukiswa Kwekhemisi Yesimanje
Ukuthuthukiswa kwekhemisi yesimanje kuyingqophamlando ebalulekile emlandweni wezokwelapha, okuletha izinguquko ezinkulu endleleni esiphatha ngayo impilo nezifo. Lokhu kuthuthuka akubandakanyi nje kuphela ukutholakala kwemithi emisha kodwa futhi nentuthuko kwezobuchwepheshe, imithethonqubo, kanye nemikhuba yemithi esebenza kahle nephephile. Lesi sihloko sizohlola izici ezahlukahlukene zokuthuthukiswa kwekhemisi yesimanje, kusukela emlandweni wayo wokuqala kuya kokusungula izinto ezintsha kwamanje.
Umlando Wokuqala Wekhemisi
Kusukela ezikhathini zasendulo, abantu bebefuna izindlela zokwelapha izifo besebenzisa izithako zemvelo. Ikhemisi, elisuselwa egameni lesiGreki elithi "pharmakon," elisho umuthi, lishintshe lisuka enkambisweni yendabuko laba yisifundo sesayensi esiyinkimbinkimbi. Ezikhathini zasendulo, osokhemisi babaziwa ngokuthi abaphilisi noma ososayensi be-alchemy, behlanganisa izithako zemvelo ukuze benze imithi elula.
I-Renaissance yabona intuthuko enkulu kwezesayensi nobuchwepheshe eyathonya intuthuko yekhemisi. Ukusetshenziswa kwezindlela zesayensi kwasiza osokhemisi ukuqonda izindlela zokusebenza kwemithi nokuthuthukisa ukusebenza kahle nokuphepha kwayo. Ukusungulwa kwe-microscope kanye namanye amasu amakhemikhali kwavula indlela yokuhlonza izithako ezisebenzayo ezitshalweni namaminerali.
Isikhathi Sokuthuthukiswa Kwesimanje
Ukuthuthukiswa kwemithi yesimanje kwaqala ngempela ukubonakala ngekhulu le-19 nasekuqaleni kwelama-20 ngokutholakala kwemithi eyahlukahlukene yokwenziwa. Enye yezinto ezibaluleke kakhulu ezatholwa yi-aspirin yiBayer ngasekupheleni kwawo-1890. I-aspirin ayizange nje ibe ngomunye wemithi yokudambisa izinhlungu ethandwa kakhulu kodwa futhi yavula indlela yokuthuthukiswa kweminye imithi yokulwa nokuvuvukala.
Ekuqaleni kwekhulu lama-20, inkolelo-mbono yamagciwane yayisivele yamukelwa kabanzi, okwaholela ekuthuthukisweni kwama-antibiotic. Ukutholakala kuka-Alexander Fleming kwe-penicillin ngo-1928 kwaba yinguquko enkulu emlandweni wekhemisi. I-Penicillin ayizange nje ibe umuthi osebenza kahle kakhulu wokulwa nokutheleleka ngamagciwane kodwa futhi yakhuthaza ucwaningo olwengeziwe ekuthuthukisweni kwamanye ama-antibiotic.
Ukusungula Izinto Ezintsha Nobuchwepheshe
Ngokuthuthuka kwesayensi nobuchwepheshe, umkhuba wekhemisi usuthuthuke kakhulu futhi wahleleka. Ubuchwepheshe bolwazi nokuxhumana bushintshe indlela osokhemisi abenza ngayo imisebenzi yabo, kusukela ekuphathweni kwemithi kuya ekunakekelweni kweziguli. Izinhlelo zokunikeza imithi nge-elekthronikhi, amarekhodi ezokwelapha nge-elekthronikhi, kanye nemikhakha yokunakekela imithi kuye kwandisa ukusebenza kahle nokuphepha ekusebenzeni kwekhemisi.
I-biosynthesis kanye ne-biotechnology yimikhakha emibili ethintwe kakhulu yintuthuko yezobuchwepheshe. I-biosynthesis ivumela ukukhiqizwa kwemithi esebenzisa izinto eziphilayo, njengebhaktheriya noma imvubelo, ukukhiqiza izinto eziwusizo ekwelapheni. I-insulin iyisibonelo esivelele somuthi we-biosynthesis, oye waba nomthelela omkhulu ekuphathweni kwesifo sikashukela.
Eminyakeni eyishumi edlule, ucwaningo lwe-pharmacogenomics kanye nokwelashwa okusekelwe ku-gene luye lwanezela isici esisha kwezokwelapha. I-Pharmacogenomics ihlola ukuthi ukuhlukahluka kofuzo komuntu ngamunye kuthinta kanjani impendulo yemithi, okwenza kube nendlela yokwelapha eyenzelwe wena. Ukwelashwa okusekelwe ku-gene kunikeza ithuba lokwelapha izifo ezazingelapheki ngaphambilini ngokufaka noma ukulungisa izakhi zofuzo ezinephutha.
Umthethonqubo Nokuphepha
Umthethonqubo uyisici esibalulekile sokuthuthukiswa kwemithi yesimanje, okuqinisekisa ukuphepha nokusebenza kahle kwemithi. Izinhlangano ezilawulayo ezifana ne-Food and Drug Administration (FDA) e-United States kanye ne-European Medicines Agency (EMA) eYurophu zidlala indima ebalulekile ekuhlolweni, ekuvunyelweni, nasekuqondisweni kwemithi emisha.
Inqubo yokuthuthukiswa kwemithi kanye nokuvunyelwa kwayo ihilela izivivinyo zemitholampilo eziqinile ukuqinisekisa ukuphepha nokusebenza kahle kwayo. Izivivinyo zemitholampilo zenziwa ngezigaba eziningana, kusukela ekuhlolweni kokuqala kwezilwane kuya ekuhlolweni okukhulu kwabantu. Yonke idatha eqoqwe ngesikhathi sezivivinyo zemitholampilo ihlaziywa ngokuningiliziwe ngaphambi kokuba umuthi uvunyelwe ukumaketha.
Ngaphezu kwalokho, imikhuba eqinile yokuqapha imithi iyadingeka ukuze kuqashwe imiphumela emibi noma ukusabela okubi ngemva kokumakethwa komuthi . Lokhu kubalulekile ukuqinisekisa ukuthi izinzuzo zomuthi zidlula izingozi zawo.
Umkhuba Wekhemisi Yezokwelapha Nokunakekelwa Kweziguli
Emashumini eminyaka amuva nje, indima yabasokhemisi ishintshe kusukela ekuhlinzekeni ngemithi kuya ekubeni yingxenye ebalulekile yethimba lezokunakekelwa kwempilo. Ikhemisi lezokwelapha liyigatsha lekhemisi eligxile ekwenzeni ngcono ukwelashwa ngemithi yeziguli. Abasokhemisi bezokwelapha babambisana nodokotela kanye nabanye ochwepheshe bezokunakekelwa kwempilo ukuthuthukisa izinhlelo zokwelapha ezisebenza kahle kakhulu nezenzelwe wena uqobo zeziguli.
Indima yosokhemisi ekubonisaneni ngemithi, ukuphathwa kokwelashwa, kanye nokufundiswa kweziguli nayo iba yinto ebaluleke kakhulu. Isibonelo, osokhemisi banikeza izeluleko ngokusetshenziswa kahle kwemithi, ukusebenzisana okungenzeka kwemithi , kanye nokulawula imiphumela emibi.
Izinselele Nekusasa
Naphezu kwentuthuko enkulu kwezesayensi nobuchwepheshe bezokwelapha, imboni ibhekene nezinselele eziningi. Enye yalezi ukwanda kokumelana nama-antibiotic, okudinga ukutholakala kwama-antibiotic amasha noma ezinye izindlela zokulawula ukutheleleka ngamagciwane.
Izindleko eziphezulu zokuthuthukiswa kwemithi nazo ziyinselele enkulu. Inqubo yocwaningo nokuthuthukiswa kusukela ezigabeni zokuqala kuya ekuvunyelweni ingathatha iminyaka futhi ibize izigidigidi zamaRandi. Lokhu kuholela emananini aphezulu emithi emisha, okungaba umthwalo ezinhlelweni zezempilo kanye neziguli.
Noma kunjalo, ikusasa lemithi liyathembisa, kunezindlela eziningi ezintsha eziseduze. Ubuchwepheshe obufana nobuhlakani bokwenziwa (AI) kanye nokufunda komshini buyasetshenziswa ukusheshisa ukutholakala kwemithi nokuthuthukisa ukuxilongwa nokwelashwa kwezifo. I-AI ingahlaziya idatha eningi ukuthola amaphethini angase angabonakali kubacwaningi babantu, isheshise ukuthuthukiswa kwezindlela zokwelapha ezintsha.
I-nanotechnology ivula nomnyango wokulethwa kwemithi okuphumelelayo kakhudlwana. Ngokusebenzisa ama-nanoparticles, imithi ingaqondiswa ngqo kumaseli noma ezicutshini ezidingayo, kuncishiswe imiphumela emibi futhi kwandiswe ukusebenza kahle.
Ukusetshenziswa kwe-big data ekunakekelweni kwezempilo kuvumela ukuqoqwa nokuhlaziywa kwedatha eningi engasiza ekubikezeleni imiphumela emibi, ukuhlonza amaphutha emithi angaba khona, nokuthuthukisa ukuphepha kwesiguli.
Isiphetho
Intuthuko yekhemisi yesimanje ihambe ibanga elide, kusukela ekusetshenzisweni kwamakhambi endabuko kuya kubuchwepheshe obuthuthukisiwe esibaziyo namuhla. Intuthuko kwezesayensi yezemithi, ubuchwepheshe, imithethonqubo, kanye nokusebenza kube nomthelela omkhulu empilweni yomphakathi. Naphezu kwezinselelo eziningi, ikusasa lekhemisi lisathembisa, kanye nezinto ezintsha ezizoqhubeka nokuguqula indlela esiqonda futhi siphatha ngayo impilo.
Osokhemisi namuhla badlala indima ebalulekile hhayi nje kuphela njengabahlinzeki bemithi kodwa futhi njengengxenye ebalulekile yethimba lezokunakekelwa kwempilo, behlinzeka ngokunakekelwa okuphelele kweziguli. Ngokuthuthuka kobuchwepheshe nolwazi, ikhemisi yesimanje inikeza izixazululo ezisebenzayo, eziphephile, neziqondene nomuntu siqu ezinseleleni ezahlukene zezempilo ezibhekene nomphakathi.
