ʻO ke koʻikoʻi o ka sodium cyanide i ka ʻoihana lāʻau lapaʻau

ʻOiai kona ʻano ʻawahia loa, he kuleana koʻikoʻi a multifaceted ka sodium cyanide (NaCN) i ka ʻoihana lāʻau lapaʻau . Ma ke ʻano he mea maka koʻikoʻi i ka synthesis organik, lawelawe ia ma ke ʻano he poloka hale kumu no ke kūkulu ʻana i nā ʻano molekala lāʻau like ʻole. Ke ʻeli nei kēia ʻatikala i nā hana koʻikoʻi o ka Sodium cyanide i ka hana lāʻau lapaʻau a me nā hana palekana koʻikoʻi e pili ana i kona hoʻohana ʻana.

ʻO Sodium Cyanide ma ke ʻano he Synthetic Intermediate: He "Molecular Scalpel"

ʻO ka hui cyano (-CN) i hāʻawi ʻia e Sodium Cyanide ke kumu o kona waiwai i ka hana ʻana i nā lāʻau lapaʻau. Ke komo nei kēia hui i kekahi mau ʻanuʻu koʻikoʻi:

Introduction of Nitrogen - loaʻa nā Pūʻulu Hana

Hiki ke hoʻololi ʻia ka hui cyano i mau pūʻulu hana pono ʻē aʻe. No ka laʻana, ma o ka hydrolysis, hiki ke hoʻololi ʻia i hui carboxylic acid (-COOH), a ma o ka hoʻemi ʻana, hiki ke lilo i pūʻulu amino (-NH₂). ʻO kēia mau pūʻulu he mau wahi hana i nā lāʻau lapaʻau he nui. I loko o nā lāʻau lapaʻau, hiki i ka hui carboxylic acid ke komo i ka hoʻopaʻa ʻana i nā paia cell bacteria, e kāohi ana i ko lākou ulu ʻana. I loko o nā lāʻau lapaʻau anti-cancer, hiki i nā hui amino ke launa pū me nā mea loaʻa kikoʻī i nā maʻi maʻi maʻi, ke keʻakeʻa nei i kā lākou hoʻonui ʻana. No ka laʻana, i ka synthesis o kekahi cephalosporin - type antibiotics, ʻo ka hoʻololi ʻana o ka pūʻulu cyano i kahi hui carboxylic acid kahi hana nui i ka hana ʻana i ka lāʻau lapaʻau ikaika.

Ke kūkulu ʻia ʻana o nā iwi molekala paʻakikī

He mea pono ʻole ka sodium cyanide no ke kūkulu ʻana i nā ʻano molekala paʻakikī. ʻO ka synthesis o ka huaora B12, kahi meaʻai koʻikoʻi no ke olakino kanaka, e hilinaʻi ana i ka hoʻohui ʻana o ka hui cyano me nā iona cobalt. He mea koʻikoʻi kēia hoʻohui ʻana no ka hoʻokumu ʻana i ke ʻano kū hoʻokahi o ka huaora B12, he mea nui ia no ka hana nerve a me ka synthesis DNA. I ka synthesis o nā β-blockers e like me propranolol, hoʻohana ʻia ka sodium cyanide e hoʻolauna i kahi kaulahao ʻaoʻao koʻikoʻi. ʻO kēia kaulahao ʻaoʻao ke kuleana no ka hiki o ka lāʻau ke ālai i nā mea loaʻa beta-adrenergic, no laila e hōʻemi ana i ka helu o ka puʻuwai a me ke koko. ʻO kekahi laʻana i ka synthesis o ka lāʻau anti-cancer 5-fluorouracil. Pili ka sodium cyanide i ke kūkulu ʻana o ke apo pyrimidine, kahi e hoʻopilikia pololei ai i ka hana anti-tumor o ka lāʻau. ʻO ka hoʻonohonoho pololei ʻana o nā ʻātoma i loko o ke apo pyrimidine, i hoʻomaʻamaʻa ʻia e ka hoʻohana ʻana o ka sodium cyanide i ke kaʻina hana synthesis, e ʻae iā 5-fluorouracil e hoʻopilikia i ka synthesis DNA a me RNA i loko o nā cell cancer.

Ke hoʻokele nei i nā ʻano hana kemika nui

ʻO ka pane ʻana o ka cyanidation

Komo ka sodium cyanide i nā hopena hoʻololi nucleophilic (e like me SN2). Ma kēia hopena, hiki i ka hui cyano ke pani i ka ʻātoma halogen o kahi hydro Carbon halogenated e hana i kahi hui nitrile. No ka laʻana, i ka synthesis o ka lāʻau antimalarial chloroquine, ua hoʻokumu ʻia ka α - chloro valeronitrile, kahi waena, ma o ia ʻano hopena. A laila hiki ke hoʻololi hou ʻia ka hui nitrile ma α - chloro valeronitrile ma o nā hopena ma hope e kūkulu i ka ʻano paʻakikī o ka chloroquine, kahi mea kūpono i ka mālama ʻana i ka malaria ma ke keakea ʻana i ke ala detoxification heme o ka parasite.

Strecker Synthesis

Hoʻopili kēia pane ʻana i ka sodium cyanide e hana ana me kahi aldehyde/ketone a me ka amonia e hana i kahi α - amino nitrile, hiki ke hoʻoheheʻe ʻia no ka loaʻa ʻana o kahi amino acid. ʻO nā amino acid nā mea kūkulu hale o nā lāʻau protein. No ka laʻana, hiki ke hana ʻia ka alanine, kahi amino acid ma o ka Strecker reaction. I loko o ka ʻoihana lāʻau lapaʻau, hoʻohana ʻia nā amino acid non-natural a kūlohelohe i kēia ala ma ke ʻano he lāʻau lapaʻau ikaika iā lākou iho a i ʻole he mau mea koʻikoʻi no nā molekala lāʻau paʻakikī. Ke hilinaʻi nei kekahi mau lāʻau lapaʻau peptide i nā waikawa amino kikoʻī i hoʻohui ʻia me ka sodium cyanide - nā hopena mediated e hoʻokō ai i kā lākou hopena therapeutic, e like me ke ʻano o kekahi mau analogs insulin kahi e pono ai ke kaʻina pololei a me ke ʻano o nā waikawa amino, me nā mea i loaʻa mai Strecker - type syntheses, he mea koʻikoʻi no ka hana hoʻoponopono glucose kūpono.

Pane Kaʻikala

Hiki i ka hui cyano ke komo i ka intramolecular cyclization e hana i ka nitrogen - i loko o nā heterocycles, e like me pyridine a me pyrimidine. Loaʻa kēia mau hale i nā lāʻau antiviral e like me oseltamivir (Tamiflu) a me nā lāʻau anti-AIDS. I loko o ka oseltamivir, ke apo pyrimidine, i hana ʻia me ke kōkua o nā hopena e pili ana i ka hui cyano mai ka sodium cyanide, he mea nui ia no ka hiki o ka lāʻau lapaʻau ke kāohi i ka maʻi influenza neuraminidase enzyme. ʻO kēia keʻakeʻa e pale i ka hoʻokuʻuʻiaʻana mai nā pūnaewele i hoʻopiliʻia, pēlā e ho'ēmi ai i ka laha o ka maʻi i loko o ke kino. I nā lāʻau anti - AIDS, hiki i ka nitrogen - loaʻa nā heterocycles ke launa pū me ka enzyme reverse transcriptase o ka maʻi HIV, e pale ana i kāna kaʻina hana.

Hoʻomalu maikaʻi a me ka mālama palekana

Hāʻawi ʻia i ka ʻona nui o ka sodium cyanide, ua hoʻoponopono paʻa ʻia kāna noi i ka ʻoihana lāʻau lapaʻau:

Hoʻomalu kaʻina hana piha

Mai ke kūʻai ʻana i ka sodium cyanide a hiki i kona mālama ʻana a me ka hoʻohana ʻana, pono nā hana āpau e hoʻokō me nā "Regulations on the Safety Management of Hazardous Chemicals." Hoʻokomo pinepine ʻia nā ʻōnaehana laka pālua, kahi e koi ʻia ai ʻelua mau mea ʻae e komo i ka sodium cyanide i mālama ʻia i ka manawa like. Hoʻohana ʻia ka nānā ʻana i ka manawa maoli e nānā i ka nui a me kahi o ka sodium cyanide i nā manawa āpau. E hōʻoia kēia e ʻike koke ʻia kahi komo ʻole a i ʻole leakage paha. No ka laʻana, i loko o kahi hale hana lāʻau lapaʻau, hoʻokomo ʻia nā mea ʻike i nā wahi mālama e ʻike ai i ka neʻe ʻana o ka cyanide i ka lewa, a ua kaupalena ʻia ke komo ʻana i ka wahi e waiho ai ma o ka hōʻoia biometric a me nā code palekana, me nā moʻolelo o nā hanana komo āpau e hoʻopaʻa ʻia.

Kaʻina Hana

Ke hoʻohana nui ʻia nei nā ʻenehana holomua e like me nā microchannel reactors. Hāʻawi nā microchannel reactors i nā pono he nui. Hiki iā lākou ke hoʻomalu pono i nā kūlana pane, e like me ka mahana, ke kaomi, a me nā kahe kahe o ka reactant, ma kahi pae micro-scale. ʻAʻole kēia e hōʻemi wale i ka hopena o ka hoʻolaha ʻana o ka sodium cyanide i ka wā e loaʻa ai nā hopena i loko o kahi kaiapuni i hoʻopaʻa ʻia a hoʻopaʻa ʻia akā hoʻomaikaʻi pū i ka maikaʻi o ka hopena a me ke koho. No ka laʻana, i ka hopena e pili ana i ka sodium cyanide e synthesize i kahi kikowaena lāʻau kūikawā, hiki i ka microchannel reactor ke hōʻoia i ka hopena o ka hopena me kahi hua kiʻekiʻe o ka huahana i makemake ʻia me ka hōʻemi ʻana i ke kūkulu ʻia ʻana o nā huahana makemake ʻole, hiki ke loaʻa ke koena cyanide.

ʻImi i nā ʻenehana ʻokoʻa

I ka hoʻoikaika ʻana e hōʻemi i ka pōʻino o ke kaiapuni, ke ʻimi ʻia nei nā ʻano ʻōmaʻomaʻo e like me ka biocatalysis (e hoʻohana ana i nā enzymes like nitrile hydratase) a me ka cyanidation electrochemical. Hāʻawi ʻo Biocatalysis i kahi ala ʻoi aku ka maikaʻi o ke kaiapuni no ka mea e hoʻohana ana i nā enzymes e hoʻokalakupua i nā hopena ma lalo o nā kūlana ʻoluʻolu. Hiki i ka Nitrile hydratase ke hoʻololi i nā nitriles (hiki ke loaʻa mai ka sodium cyanide - based reactions) i loko o nā amides me ka ʻole o ka pono o nā reagents kemika. Hiki i ka electrochemical cyanidation, ma ka ʻaoʻao ʻē aʻe, hiki ke hōʻemi i ka nui o ka sodium cyanide i hoʻohana ʻia e ka ʻae ʻana i nā hopena ʻoi aku ka maikaʻi a me ka manaʻo ma o ka hoʻohana ʻana i kahi au uila. ʻOiai aia kēia mau ʻenehana ʻē aʻe i ka pae hoʻomohala i kekahi mau hihia, paʻa lākou i ka ʻōlelo hoʻohiki nui no ka wā e hiki mai ana o ka ʻoihana lāʻau lapaʻau i ka hōʻemi ʻana i kona hilinaʻi ʻana i ka sodium cyanide nui loa i ka wā e mālama ana i ka hiki ke hoʻohui i ka lāʻau.

Nā ʻano o ka wā e hiki mai ana: Ke kaulike ʻana i ka palekana a me ka maikaʻi

Hoʻonohonoho ʻana o ke Kemika ʻōmaʻomaʻo

ʻO ka wā e hiki mai ana o ka hoʻohana ʻana i ka sodium cyanide i ka ʻoihana lāʻau lapaʻau e pili ana i ka hoʻomohala ʻana i nā ala hoʻokō cyanide - manuahi. ʻO kahi ala e hoʻohana ai i ka metala - organic frameworks (MOFs). ʻO nā MOF he mau mea porous me nā hale kūʻokoʻa e hiki ke koho a hoʻoulu i ka hui cyano. Hāʻawi kēia i ka hoʻohana pono ʻana o ka hui cyano i nā hopena ʻoiai e hōʻemi ana i ka nui o ka sodium cyanide e pono ai ma ke ʻano he mea maka. Ma ka hōʻemi ʻana i ka hoʻohana ʻana i nā mea maka, ʻaʻole kēia e hōʻemi wale i ka hopena o ke kaiapuni e pili ana i ka sodium cyanide akā hiki ke hoʻohaʻahaʻa i nā kumukūʻai hana. No ka laʻana, i loko o kahi noiʻi noiʻi ʻenehana, ua hoʻohana ʻia nā MOF no ka hoʻoulu ʻana i kahi pane e koi pinepine ai i ka sodium cyanide. Ua hōʻike ʻia nā hopena i hiki i ka MOF - catalyzed reaction ke hoʻokō i kahi hua like o ka huahana i makemake ʻia me ka hoʻemi nui ʻana o ka nui o ka sodium cyanide input.
