Aikace-aikacen Sodium Cyanide a cikin Masana'antar Magunguna

sodium cyanide, tare da tsarin sinadarai NaCN, fari ne, mai narkewa, kuma fili mai guba. Duk da sanannen suna saboda gubarsa, yana taka muhimmiyar rawa a cikin Masana'antu a matsayin wani muhimmin sinadaran reagent a daban-daban roba tafiyar matakai.

1. Haɗin Matsakaici

1.1 Cyanohydrin Synthesis

Daya daga cikin muhimman aikace-aikace na sodium Cyanide a Pharmaceutical kira ne a cikin samuwar cyanohydrins. Lokacin da aldehyde ko ketone ya amsa sodium cyanide A gaban sinadarin acid catalyst (yawanci acid mai rauni), ana samar da cyanohydrin. Tsarin amsawar ya haɗa da ƙara sinadarin cyanide ion (CN-) zuwa nucleophilic. Carbonyl carbon na aldehyde ko ketone. Misali, a cikin hada mandelonitrile, benzaldehyde yana amsawa da Sodium cyanide. Ana wakilta wannan martani kamar haka:

Mandelonitrile da sauran cyanohydrins sune mahimman tsaka-tsaki a cikin haɗin magunguna daban-daban. Za a iya ƙara rikiɗa su zuwa mahadi tare da ayyuka daban-daban na ilimin halitta, kamar alpha - hydroxy acid da alpha - amino acid, waɗanda ke cikin sassan magunguna da yawa.

1.2 Nitrile Synthesis

Sodium cyanide kuma ana amfani dashi sosai don haɗa nitriles. A cikin SN2 (masanya nucleophilic bimolecular dauki), alkyl halides suna amsawa da sodium cyanide don samar da nitriles. Alal misali, lokacin da bromoethane ya amsa tare da sodium cyanide, an kafa propionitrile:

Nitriles tubalan gini iri-iri ne a cikin sinadarai na harhada magunguna. Ana iya sanya su cikin hydrolyzed zuwa acid carboxylic, a rage su zuwa amines, ko kuma a kara mayar da martani don samar da mahadi na heterocyclic. Magunguna da yawa sun ƙunshi ƙungiyoyin aikin nitrile, waɗanda ke ba da gudummawa ga kaddarorin su na harhada magunguna, kamar a cikin wasu magungunan antifungal da ƙwayoyin cuta.

2. Samar da Magunguna na Musamman

2.1 Cyanocobalamin (Vitamin B12) Haɗin kai

Cyanocobalamin, wanda aka fi sani da bitamin B12. bitamin ne mai mahimmanci ga lafiyar ɗan adam. Haɗin cyanocobalamin ya ƙunshi amfani da sodium cyanide. A mataki na ƙarshe na wasu hanyoyi na roba, an mayar da cobalt - dauke da matsakaici tare da sodium cyanide don gabatar da ƙungiyar cyanide, wanda shine halayyar cyanocobalamin. Ƙungiyar cyanide a cikin cyanocobalamin yana da ɗan kwanciyar hankali a ƙarƙashin yanayin yanayin jiki kuma yana taka rawa a cikin ayyukan nazarin halittu na bitamin. Vitamin B12 yana da mahimmanci ga haɗin DNA, aikin jijiya, da kuma samar da jajayen ƙwayoyin jini, da kuma samar da shi ta hanyar yin amfani da sodium cyanide yana taimakawa wajen biyan buƙatun kayan abinci da kayan aikin magunguna.

2.2 Haɗin Wasu Magungunan Magungunan Kansa

A cikin ci gaban wasu magungunan ciwon daji, ana amfani da sodium cyanide a cikin haɗin maɓalli masu mahimmanci. Alal misali, a cikin haɗakar wasu indole-based anti-cancer mahadi, ana amfani da sodium cyanide a cikin jerin halayen don gina tsarin kwayoyin halitta. Ƙungiyoyin nitrile da sodium cyanide suka gabatar za a iya ƙara gyaggyarawa don haɓaka alaƙar miyagun ƙwayoyi ga ƙwayoyin cutar kansa, hana takamaiman enzymes da ke cikin haɓakar ƙwayar cutar kansa, ko rushe hanyoyin rayuwa na ƙwayar cutar kansa.

3. Kalubale da Rigakafin Amfani da Sodium Cyanide

Yin amfani da sodium cyanide a cikin masana'antar harhada magunguna yana zuwa tare da ƙalubale masu mahimmanci saboda matsananciyar guba. Ana buƙatar matakan tsaro mai ƙarfi a cikin sarrafa shi, ajiya, da amfani. Kayan aiki na musamman da ƙwararrun ma'aikata suna da mahimmanci don hana kowane yatsa ko fallasa. A cikin tsarin masana'antu, ana shigar da tsarin samun iska mai kyau don kauce wa shakar kowane cyanide - mai dauke da hayaki. Bugu da ƙari, sarrafa sharar gida abu ne mai mahimmanci. Duk wani sharar da ke ɗauke da sodium cyanide ko samfuran amsawa dole ne a kula da su a hankali don tabbatar da amincin muhalli. Yawancin lokaci, ana amfani da hanyoyin oxidation don canza mahaɗan cyanide masu guba sosai zuwa abubuwan da ba su da illa kafin zubar.

4. Ra'ayoyin gaba

Yayin da masana'antar harhada magunguna ke ci gaba da bunƙasa, ana ci gaba da neman ƙarin ingantattun hanyoyin haɗin gwiwa da aminci. Duk da yake sodium cyanide ya kasance mai mahimmanci reagent a halin yanzu pharmaceutical kira, ana kokarin samar da madadin hanyoyin da ko dai rage ko kawar da amfani da wannan sosai m fili. Duk da haka, nan gaba kadan, saboda sake kunnawa na musamman na sodium cyanide a wasu hanyoyi na roba, yana yiwuwa ya ci gaba da taka rawa wajen samar da wasu magunguna. Bincike na iya mayar da hankali kan haɓaka ƙarin yanayin amsawa don rage haɗarin da ke tattare da amfani da shi da kuma gano ingantattun analogs ko wasu dabarun roba waɗanda zasu iya cimma samfuran magunguna iri ɗaya tare da rage damuwa mai guba.

A ƙarshe, sodium cyanide, duk da gubarsa, ya ba da gudummawa mai mahimmanci ga masana'antar harhada magunguna a cikin haɗin magunguna daban-daban da masu tsaka-tsaki. Amfani da shi daidai da aminci, tare da ci gaba da ƙoƙarin nemo wasu hanyoyi, zai zama mahimmanci ga ci gaba mai dorewa na masana'antar magunguna.
