and four kinds of aprotic solvents (acetonitrile, dichloromethane, ethyl acetate and acetone). Sulforaphene was found to be stable in aprotic solvents and unstable in the protic solvents. The degradation products of sulforaphene in protic solvents (methanol and ethanol) were purified by the preparative HPLC and identified by ESI/MS and NMR ((1)H NMR). The degradation pathways of sulforaphene in methanol
磺胺噻吩,一种天然化合物,已被研究为潜在的抗癌药。然而,尚未适当报道磺胺噻吩在各种溶剂中的稳定性及其降解途径。这种不稳定性损害了制备过程,生物学评估实验以及对噻吩甲酚的应用。在这项研究中,研究了以下六种溶剂分别在26°C下储存的对噻吩甲醚的稳定性:两种质子传递溶剂(甲醇和乙醇)和四种非质子传递溶剂(乙腈,二氯甲烷,乙酸乙酯和丙酮)。磺胺噻吩在非质子传递溶剂中稳定,在质子传递溶剂中不稳定。通过制备型HPLC纯化质子溶剂(甲醇和乙醇)中对苯二酚的降解产物,并通过ESI / MS和NMR((1)H NMR)进行鉴定。提出了磺胺噻吩在甲醇和乙醇中的降解途径。结果发现,磺胺噻吩在醇中被降解为两种结构异构体。
