K-Oxyma 是 Oxyma Pure 的钾盐,是一种用于肽键形成的肟类偶联添加剂。其钾盐形式在 DMF 中具有更好的溶解性,并适用于 2-氯三苯甲基树脂等高度酸敏感的固相载体。K-Oxyma 可用于碳二亚胺介导的肽偶联,并有助于降低偶联过程中的差向异构化。
应用
HOBt和HOAt的非爆炸性替代品,性能与HOAt至少相当在空间要求严格的肽键形成中性能胜过HOAt与碳二亚胺介导的过程相兼容;溶液和固相肽偶联;片段缩合反应中的差向异构现象少于HOBtK盐特别适用于在弱酸不稳定的树脂(如2-氯三苯甲基)上进行肽偶联;由于其具有更强的碱性,因此使得肽从树脂上脱离的概率降至最低甚至没有K盐的熔点高于OxymaPure
K-Oxyma is the potassium salt of Oxyma Pure and is an oxime-based coupling additive for peptide bond formation. The potassium salt has improved solubility in DMF and is compatible with highly acid-labile solid supports such as 2-chlorotrityl resin. It can be used in carbodiimide-mediated peptide coupling while helping to limit epimerization.
Description
Non-explosive replacement for HOBt and HOAt with at least comparable performance to HOAtOutperforms HOAt in sterically demanding peptide bond formationsCompatible with carbodiimide-mediated; solution and solid phase peptide coupling;Less epimerization than HOBt in fragment condensation reactionsK-salt especially useful in peptide coupling on mild acid-labile resins such as 2-chlorotrityl; leading to minimal to no cleavage of the peptide from the resin due to its more alkaline characterK-salt has a higher melting point than OxymaPure
