INGINGO ZOSE N'AMAKURU Y’IBICURUZWA BITANZWE KURI URU RUBUGA BISANZWE KUBONA AMAKURU N'INTEGO Z'UBUREZI.
Ibicuruzwa byatanzwe kururu rubuga bigenewe gusa mubushakashatsi bwa vitro. Mu bushakashatsi bwa vitro (Ikilatini: * mu kirahure *, bisobanura mu bikoresho by'ibirahure) bikorwa hanze y'umubiri w'umuntu. Ibicuruzwa ntabwo ari imiti, ntabwo byemejwe n’ikigo cy’Amerika gishinzwe ibiryo n’ibiyobyabwenge (FDA), kandi ntigomba gukoreshwa mu gukumira, kuvura, cyangwa gukiza indwara iyo ari yo yose y’ubuvuzi, indwara, cyangwa indwara. Birabujijwe rwose n'amategeko kwinjiza ibyo bicuruzwa mumubiri wabantu cyangwa inyamaswa muburyo ubwo aribwo bwose.
Peptide Solubility ni iki?
Peptide solubilité bivuga umubare ntarengwa wa peptide ushobora gushonga mubunini bwumubyimba wubushyuhe bwihariye nubushyuhe bwa pH, mubisanzwe birangwa nubushuhe bwinshi (g / L) cyangwa kwibumbira hamwe (mol / L). Nkumutungo wingenzi wa fiziki-chimique, bigira uruhare runini muburyo bwo kwinjiza, gukwirakwiza, metabolisme, no gusohora (ADME) ya peptide muri vivo, kandi ikanagena ikoranabuhanga ryitegura, ihagarikwa ryububiko, hamwe nubuvuzi bukoreshwa nubuvuzi bwa peptide.
Ibintu by'ingenzi bigira ingaruka kuri Peptide
Peptide solubile igenwa nuburyo bwimiterere ya molekuline hamwe nibidukikije byo hanze. Kurwego rwa molekile, acide polar amino yongerera hydrophilicity binyuze mumigozi ya hydrogène cyangwa imiyoboro ya ionic, bityo igatezimbere; acide aminide acide ikunda kwegeranya kubera imikoranire ya hydrophobique, igabanya ubukana. Peptide ngufi ikunze kwerekana imbaraga nyinshi kuruta peptide ndende kubera ubunini bwa molekile ntoya ningaruka zo gukiza gukomeye. Peptide hamwe nogukwirakwiza kwishyurwa bifite solubilité nyinshi kubiciro bya pH bikwiye kubera kugabanuka kwegeranya biterwa no kwanga electrostatike. Mubintu byo hanze, solvent polarite, pH agaciro, nimbaraga za ionic byose bigira ingaruka zikomeye kumyitwarire yo gusesa.
Uburyo busanzwe bwo gupima Peptide Solubility
Uburyo bwa equilibrium burimo kuvanga peptide irenze hamwe na solde, gukurura ubushyuhe burigihe kugeza igihe iringaniza rigeze, hanyuma ukamenya ubunini bwindengakamere nyuma ya centrifugation. Ubu buryo buroroshye gukora ariko busaba umwanya muremure wo kuringaniza, bigatuma bukwiranye na peptide ifite imbaraga nke. Uburyo bwa spekitroscopique bukoresha isano iri hagati yo kwinjiza ibintu no kwibanda ku kwiyemeza byihuse, nubwo bisaba kwirinda kwivanga. Amazi meza cyane ya chromatografiya (HPLC) atuma hamenyekana neza kwibumbira hamwe kwa peptide muri sisitemu igoye bitewe nubushobozi bwayo bwo gutandukana no kumva neza, cyane cyane kuburugero burimo isomeri cyangwa umwanda. Uburyo butangaje bwo gukwirakwiza urumuri rusuzuma mu buryo butaziguye uko iseswa ryifashe hamwe n’imyitwarire ya peptide ikurikirana impinduka z’umucyo utatanye.
Ingamba zifatika zo kuzamura Peptide Solubility
Guhindura imiti bikubiyemo kumenyekanisha amatsinda ya polar kuri peptide termini cyangwa gusimbuza aside amine acide hamwe n ibisigazwa bya polar kugirango byongere hydrophilique kandi bigabanye imikoranire ya hydrophobique. Sisitemu yogukoresha neza ikubiyemo kongeramo ibishishwa (methanol, DMSO) cyangwa surfactants (SDS) kugirango tunonosore polarite cyangwa gukora micelles zo gukemura. Guhindura imiterere yo gukemura bikubiyemo guhitamo indangagaciro za pH zishingiye ku ngingo ya isoelectric kugirango ibuze kwegeranya binyuze mu kwanga kwishyurwa, mugihe ugenzura imbaraga za ionic kugirango wirinde gusohora. Igishushanyo mbonera gishobora kuba gikubiyemo gutegura nanoparticles, microsperes, cyangwa lyofilized formulaire kugirango tunonosore ibisubizo byongera imbaraga zo gukwirakwiza cyangwa guhitamo uburyo bwo gusesa. Guhitamo ingamba bigomba guhuza peptide imiterere nuburyo bukoreshwa kugirango byuzuze ibisabwa byiterambere.
