MAHARA RADICALS & ZVIRWERE

Kazhinji, mahara radicals anodikanwa kumitumbi, asi yakanyanyisa yemahara radicals inogona kukonzera kusaenzana kweiyo muviri kushanda, zvobva zvaendesa kune oxidative kusagadzikana kuchichinjika muzvirwere zvakasiyana siyana (zvinyorwa zvinoratidza kuti mahara radicals ndiwo manyuko ezvirwere zvakasiyana siyana).

ANTIOXIDANT

Miviri yedu haigone kushanda isina oxygen, uye kana huwandu hwakawanda hwemahara radicals hwakawedzera, muviri uri pasi peiyo oxidative kushushikana unozokonzeresa iyo yekugadzirisa system kutadza mukubvisa yakawandisa emahara radicals. Muzviitiko zvakakosha, muviri unoda kuzadza antioxidants in vitro kubvisa zvakanyanyisa mahara radicals.

L-ERGOTHIONEINE - RUDZIDZO Rutsva RWEZVINHU ZVINODZIDZA

EGT iri yechisiki chiral amino-acid antioxidant biosynthesized mune mamwe mabhakitiriya uye fungi. Iyo yakakosha bioactive komputa iyo yanga ichishandiswa seyakanyanya scavenger, iyo ultraviolet ray firita, mutongi weiyo oxidation-yekudzora maitiro uye maseru bioenergetics, uye yehupenyu cytoprotector, nezvimwe.
L-Ergothioneine (EGT, ERGO, CAS: 497-30-3), inozivikanwawo se (S) -pi-Carboxy-2,3-dihydro-N, N, N-trimethyl-2-thioxo-1H-imidazole- 4-ethanaminium yemukati munyu, yakatanga yakabviswa kubva ergot naTanret C muna 1909, ipapo yakawanikwawo muropa remhuka. Yakachena EGT yakachena kristaro, inonyungudirwa mumvura, (yakanyungudika 0.9mol / L pamhepo tembiricha). Autoxidation haigone kuitika pahupi pH kukosha kana mune yakasimba alkaline mhinduro. EGT inogona kuvapo mune maviri ma isomer mafomu - thiol fomu uye thione fomu, sezvakaratidzwa pasi apa:

KUSANGANISIRA

Nebatsiro remazhinji-mabasa, EGT inomira pakati pemamwe akawanda antioxidants.

ZVAKANAKIRA

pasina

Iine mabhenefiti eakawanda-mabasa, EGT inomira pakati pezvimwe zvakawanda antioxidantsMakomborero (achienzaniswa ne glutathione, cysteine ​​nezvimwewo):
----EGT zviri nyore kuunganidza mumasero uye iko kusungwa kunodzikama kupfuura mamwe antioxidants.
——EGT inonyanya kushanda pakudzora kufa kwemuviri kunokonzerwa nepyrogallol.
--—EGT inonyanya kutsvaira ROS kudzivirira oxidation, nepo glutathione nevamwe vachitsvaga radicals yemahara, ndokuti, zvimwe antioxidants scavenge oxidation zvigadzirwa.

KUFANANA KWEMWE ANTIOXIDATION

Results: EGT ndiye ainyanya kutsvagisa rusununguko radicals kana ichienzaniswa neyekare antioxidants seGSH, uric acid uye trolox. Kunyanya, iyo yepamusoro antioxidant kugona inoratidzwa neEGT vs.poxyl radicals kwakakonzera 25% kukwira kupfuura kukosha kunowanikwa nereferensi antioxidant trolox. Iko kugona kwekutsvaira kweEGT kuenda kuhydroxyl radicals yaive 60% yakakwira, zvichienzaniswa neuric acid, inomiririra chirevo antioxidant vs. hydroxyl radicals. Chekupedzisira, EGT yakaratidza yakanyanya antioxidant chiitiko zvakare kune peroxynitrite, ine simba rekutsvaira 10% yakakwira kupfuura iyo yeuric acid.
