Mkpa Sodium Cyanide dị na nrịbama ọgwụ

Okwu Mmalite

sodium cyanide, na usoro ọgwụ NaCN, bụ kristal ọcha siri ike. N'agbanyeghị ọdịdị na-egbu egbu ya, sodium cyanide na-arụ a dị mkpa na irreplaceable ọrụ na ubi nke Ngwakọta ọgwụ. Isiokwu a na-abanye n'ime mkpa dị omimi nke sodium cyanide na nchịkọta ọgwụ, na-enyocha ngwa ya, usoro ya, na ntinye aka na mmepe nke ndụ - ịzọpụta ọgwụ.

Njirimara kemịkalụ dị mkpa na ngwa ọgwụ

Sodium cyanide bụ ntọala siri ike - nnu acid na-adịghị ike. Ọ bụ nke ukwuu soluble na mmiri, na aqueous ngwọta bụ ike alkaline. Mgbe ọ na-emeghachi omume na acid, ọbụna acid na-adịghị ike, ọ na-etolite ngwa ngwa hydrogen cyanide. Na pharmaceutical njikọ, ndị a chemical Njirimara na-enyere sodium cyanide isonye na mmeghachi omume dị iche iche. Dịka ọmụmaatụ, ike ya ịnye ion cyanide (CN⁻) dị oke mkpa. Ion cyanide nwere ike ime dị ka nucleophile na ọtụtụ mmeghachi omume organic, na-awakpo ebe electrophilic na ogige organic. Ngwongwo nucleophilic a na-enye ohere iwebata otu cyano (-CN) n'ime ụmụ irighiri ihe mgbaru ọsọ, nke bụ nzọụkwụ dị mkpa na njikọ nke ọtụtụ. Ndị na-ere ọgwụ.

Ngwa dị na Synthesis ọgwụ

Nkwekọrịta nke ndị isi ahịa ọgwụ

1. Ọgwụ nje: Na njikọ nke ụfọdụ ọgwụ nje, sodium cyanide na-eji ewebata otu ọrụ. Dịka ọmụmaatụ, n'imepụta ụfọdụ ọgwụ nje β-lactam, otu cyano nke sodium cyanide webatara na-ekere òkè n'ịmepụta njirimara mgbanaka β-lactam. Enwere ike gbanwee otu cyano site na mmeghachi omume dị iche iche, na-eduga n'ịwube usoro mgbagwoju anya nke ọgwụ nje, nke dị mkpa maka ọrụ nje ha.

2. Ọgwụ mgbochi ọrịa kansa: Ọtụtụ ọgwụ mgbochi ọrịa cancer na-adabere n'ụdị molekụla akọwapụtara maka ịdị irè ha. Sodium cyanide na-etinye aka na njikọ nke ndị isi etiti maka ọgwụ ndị a. Site na iwebata otu cyano, ndị na-ahụ maka kemịkalụ nwere ike gbanwee pharmacokinetic na pharmacodynamic akụrụngwa nke mkpụrụ ndụ ọgwụ ikpeazụ. Ụfọdụ ọgwụ anticancer nwere cyano - nwere ihe ndị nwere ike ịchekwa mkpụrụ ndụ kansa n'ụzọ dị irè karị, na-etinye aka na usoro metabolic ha, mmegharị DNA, ma ọ bụ cell - ụzọ mgbaàmà.

3. Ọgwụ gbasara obi: Na njikọ nke ọgwụ maka ịgwọ ọrịa obi, sodium cyanide - mmeghachi omume mgbasa ozi na-ejikarị eme ihe. Dịka ọmụmaatụ, na nkwadebe nke ụfọdụ ndị na-egbochi ọwa calcium, iwebata otu cyano nwere ike imetụta lipophilicity na ngwá electronic nke molecule. Nke a, n'aka nke ya, nwere ike imetụta ikike nke ọgwụ na-agafe sel cell, na-ejikọta ya na ndị na-anabata ya kpọmkwem na usoro obi, ma na-achịkwa ọwa calcium ion, si otú ahụ nweta mmetụta ọgwụgwọ a chọrọ.

Ịmepụta Ọdịdị Molecular mgbagwoju anya

1. Mgbanaka - akpụ mmeghachi omume: Sodium cyanide nwere ike itinye aka na mgbanaka - na-emepụta mmeghachi omume, nke dị oke mkpa maka iwulite usoro cyclic nke a na-ahụkarị n'ọtụtụ mkpụrụ ndụ ọgwụ. Dịka ọmụmaatụ, na njikọ nke ogige heterocyclic dị ka pyrimidine na purines, nke bụ akụkụ dị mkpa nke acid nucleic na ọtụtụ ọgwụ, sodium cyanide nwere ike isonye na mmeghachi omume multi-step nke na-eduga na nguzobe nke usoro cyclic ndị a. Enwere ike itinye otu cyano n'ime usoro mmeghachi omume, na site na hydrolysis na-esote, cyclization, na mmeghachi omume ndị ọzọ, a na-emepụta mgbanaka heterocyclic ikpeazụ.

2. Synthesis stereoselective: N'ime usoro ọgwụ, imezu stereoselectivity (nhazi nke otu stereoisomer) na-adịkarị mkpa dịka ndị stereoisomer dị iche iche nke ọgwụ nwere ike inwe nnukwu ọrụ ọgwụ dị iche iche. Enwere ike iji sodium cyanide mee ihe na mmeghachi omume nke ejiri nlezianya mee ya iji nweta nsonaazụ stereoselective. Dịka ọmụmaatụ, na njikọ nke ọgwụ chiral, enwere ike ịme ụfọdụ mmeghachi omume metụtara sodium cyanide n'ihu nke chiral catalysts ma ọ bụ n'okpuru ọnọdụ mmeghachi omume kpọmkwem iji chịkwaa stereochemistry nke ngwaahịa ahụ, na-ahụ na enwetara stereoisomer nke ọgwụ ahụ chọrọ.

Ntụnye aka na mmepe nke ọgwụ ọhụrụ

1. Ịgbasa ụdịdị kemịkalụ: Iji sodium cyanide mee ihe na nhazi ọgwụ na-enye ndị na-ahụ maka chemist ohere ịnweta ụdị kemịkal dị iche iche nke nwere ike ọ gaghị adị mfe ịnweta site n'ụzọ ndị ọzọ. Site n'iwebata otu cyano, enwere ike ịmepụta ihe ọkpụkpụ kemịkalụ ọhụrụ, nke enwere ike gbanwee ma gbasaa ọzọ. Mgbasawanye nke kemịkal dị iche iche dị mkpa maka nchọpụta ọgwụ ọhụrụ. Ụlọ ọrụ na-emepụta ọgwụ na ụlọ ọrụ nyocha na-achọkarị ndị na-achọ ọgwụ ọhụrụ, na mmeghachi omume pụrụ iche nke sodium cyanide na-enye ngwá ọrụ dị ike maka ịmepụta ụmụ irighiri ihe nwere uru ọgwụgwọ.

2. Na-akwalite nrụpụta ọgwụ na nchekwa: Iwebata nke otu cyano n'ime mkpụrụ ndụ ọgwụ nwere ike inwe mmetụta dị ukwuu na njirimara ha na nchekwa profaịlụ. Dịka ọmụmaatụ, otu cyano nwere ike ịbawanye lipophilicity nke ọgwụ, na-eme ka ike ya banye n'ime akpụkpọ anụ cell ma ruo ebe a na-achọsi ike n'ime ahụ. N'otu oge ahụ, ntinye kwesịrị ekwesị nke otu cyano nwekwara ike imetụta metabolism nke ọgwụ ahụ, na-ebelata ohere nke ịmepụta metabolites na-egbu egbu. Nke a dị mma - nlegharị anya nke ọgwụ ọgwụ site na iji sodium cyanide na njikọ nwere ike iduga n'ịmepụta ọgwụ na-eme ka usoro ọgwụgwọ dịkwuo mma, nke pụtara na ha dị irè karị ma nwee mmetụta dị ole na ole.

Nlekọta ihe egwu na nchebara echiche na iji sodium Cyanide

1. Nsi na ịkpachapụ anya: Sodium cyanide na-egbu egbu nke ukwuu. Ọbụlagodi ntakịrị ego nwere ike igbu mmadụ ma ọ bụrụ na etinyere ya ọnụ, kuru ya ume, ma ọ bụ banye ya n'ahụ. N'ebe a na-emepụta ọgwụ ebe a na-eji sodium cyanide, usoro nchekwa nchekwa siri ike dị. A chọrọ ka ndị ọrụ na-eyi ihe nchebe pụrụ iche, gụnyere ihe iku ume, uwe aka, na uwe nchebe. A na-arụ ọrụ niile metụtara sodium cyanide na mpaghara ikuku ventilashị nke ọma, mgbe mgbe n'ime mkpuchi uzuzu, iji gbochie ntọhapụ nke uzuzu na-egbu egbu. Na mgbakwunye, enwere iwu siri ike gbasara nchekwa na njikwa sodium cyanide iji belata ohere nke ihe mberede.

2. Mmetụta gburugburu ebe obibi na Mbelata: Ojiji nke sodium cyanide n'ime mmepụta ọgwụ na-ebutekwa nchegbu gbasara gburugburu ebe obibi. Ọ bụrụ na ihe mberede wụfuo ma ọ bụ mkpofu na-ezighi ezi, sodium cyanide nwere ike imerụ ala na mmiri. Iji dozie nke a, ụlọ ọrụ ọgwụ na-eme atụmatụ zuru oke maka ijikwa ihe mkpofu. A na-eji nlezianya agwọ iyi mkpofu nwere sodium cyanide iji mee ka cyanide ahụ dị ọcha tupu a chụpụ ya. Nke a nwere ike ịgụnye usoro oxidation kemịkalụ iji gbanwee cyanide dị oke njọ ka ọ bụrụ ihe ndị na-adịghị emerụ ahụ dịka cyanate ma ọ bụ nitrogen na carbon Na mgbakwunye, a na-eme nlekota gburugburu ebe obibi mgbe niile iji hụ na mmetụta nke ọrụ mmepụta ọgwụ na gburugburu ebe obibi belatara.

mmechi

Sodium cyanide, n'agbanyeghị nsi sitere na ya, bụ reagent dị mkpa na njikọ ọgwụ. Ngwongwo kemịkalụ ya pụrụ iche na-enyere aka ịmepụta ụdị dị iche iche nke ọgwụ etiti na iwu ihe owuwu molekụla dị mgbagwoju anya. Ọ na-ekere òkè dị mkpa na mmepe nke ọgwụ maka ịgwọ ọrịa dị iche iche, site na ọgwụ nje maka ọrịa na-efe efe na ọgwụ mgbochi ọrịa cancer na ọgwụ maka ọnọdụ obi. Agbanyeghị, ojiji ya ga-esonyere ya na usoro nchekwa siri ike na njikwa gburugburu ebe obibi.
