The analogues 7-9 of 7-oxaceramide and 7-oxasphingosine were synthesized from the known azidosphingosine 21. The 1,4-disubstituted 1,2,3-triazole analogues 10-16 of ceramides were synthesized by the click reaction of the known azide 24. None of the analogues 7-15 was active as inhibitor of SPHK type 1 and of acid sphingomyelinase, whereas 16 is a weak inhibitor of SPHK1. Triazoles 10, 11, and 15 did
由已知的叠氮鞘氨醇21合成7-氧杂草酰胺和7-氧杂萘新的类似物7-9。通过已知的叠氮化物的点击反应合成了1,4-二取代的1,2,3-三唑的神经酰胺类似物10-16。 24.类似物7-15均没有活性作为SPHK 1型和酸性鞘磷脂酶的抑制剂,而16种是SPHK1的弱抑制剂。三唑10、11和15不会抑制CerK引起的神经酰胺磷酸化,当被人类CD1d转染的抗原呈递细胞(APC)呈递时,7、8和10-15均不会激活不变的自然杀伤T(iNKT)细胞克隆。或通过板结合的人CD1d [55]。三唑14和15阻止α-半乳糖基神经酰胺(α-GalCer)与板结合的人CD1d结合,并防止随后的T细胞对α-GalCer的反应。
