With the aim of designing a new calcium receptor, the synthesis and the conformational analysis of a small library of dipeptides having the general formula Ac–Oxx–L-Xaa–OBn [Oxx =
L-Oxd, (4S,5R)-4-methyl-5-carboxyoxazolidin-2-one; D-Oxd, (4R,5S)-4-methyl-5-carboxyoxazolidin-2-one; or D-Oxac (4R)-(2-oxo-1,3-oxazolidin-4-yl)-acetic acid] is reported. Ac–L-Oxd–L-Ala–OBn was identified as the most promising compound by MS–ESI analysis and this outcome was confirmed by photoluminescence spectroscopy.
为了设计一种新的
钙受体,报道了一小组二肽的合成及其构象分析,具有一般式 Ac–Oxx–L-Xaa–OBn [Oxx = L-Oxd, (4S,5R)-4-甲基-5-羧基
噁唑烷-2-酮;D-Oxd, (4R,5S)-4-甲基-5-羧基
噁唑烷-2-酮;或D-Oxac (4R)-(2-氧-1,3-
噁唑烷-4-基)-
乙酸]。通过质谱-电喷雾离子化分析,识别出 Ac–L-Oxd–L-Ala–OBn 是最有前景的化合物,这一结果通过光致发光光谱得到了确认。
