可滲透細(xì)胞的九精氨酸酰胺,它可以很容易地與貨物分子結(jié)合,例如,通過馬來酰亞胺-硫醇偶聯(lián)。
Cell-permeable nonaarginine amide, which can be easily conjugated to a cargo molecule, e.g. by maleimide-thiol coupling.
它是一種由9個(gè)精氨酸殘基組成的肽,由活化的半胱氨酸殘基C(Npys)合成,其中Npys是3-硝基-2-吡啶磺?;Wo(hù)性半胱氨酸。這種含半胱氨酸的9R的S(Npys)基團(tuán)能夠選擇性地與另一種含半胱氨酸的肽的游離巰基反應(yīng)以形成不對(duì)稱的二硫鍵。巰基的偶聯(lián)已被研究為在細(xì)胞內(nèi)的還原環(huán)境中遞送/釋放治療劑如siRNA的有效手段。
It is a peptide composed of 9 arginine residues synthesized from an activated cysteine residue C(Npys), where Npys is 3-Nitro-2-pyridinesulfenyl protective cysteine. The S(Npys) group of this cysteine-containing 9R is capable of reacting selectively with the free thiol group of another cysteine-containing peptide to form an unsymmetrical disulfide bond. Coupling of sulfhydrils has been studied as an effective means to deliver/release therapeutic agents such as siRNA in the reducing environment within the cell.
