3,5-di-tert-butylbenzoic acid. Homologue [(13)CD(3)]ALRT1550 was labeled at the 7-position of the trienoic acid chain via addition of [(13)CD(3)]MgI to a Weinreb amide precursor. The preparation of [(3)H]ALRT1550 utilized novel methodology to synthesize a sterically hindered and site-specific tritium-labeled tert-butyl group. Saturation binding and Scatchard analysis of this ligand at the retinoic acid
(2E,4E,6E)-7-(3,5-二叔丁基苯基)-3-甲基辛基-2,4,6-三烯酸(ALRT1550,2)的两个标记同系物的合成[[13在此报告中描述了CD(3)] ALRT1550(3)和[(3)H] ALRT1550(4)。ALRT1550是一种非常有效的抗增殖药,目前正用于急性化学治疗的I / II期临床试验中。两种同系物均由可商购的3,5-二叔丁基苯甲酸制备。通过向Weinreb酰胺前体中添加[(13)CD(3)] MgI,将同系物[(13)CD(3)] ALRT1550标记在三烯酸链的7位。[(3)H] ALRT1550的制备利用新颖的方法来合成空间受阻和特定位置的tri标记的叔丁基。还描述了在视黄酸受体处对该配体的饱和结合和Scatchard分析,
