Novel radioiodinated analogues of naturally-occurring cholestrol esters, arylaliphatic cholesteryl ethers, are selective for low density lipoproteins and have been shown to be successful imaging agents for adrenal glands. The arylaliphatic cholesteryl ethers have the general formula: ##STR1## where X is a radioactive isotope of iodine and n is an integer between 1 and 20. Two illustrative examples, m-iodobenzyl cholesteryl ether and 12-(m-iodophenyl) dodecyl cholesteryl ether, were radiolabeled with .sup.125 I by an isotope exchange reaction. Tissue distribution studies indicate significant accumulation of the cholesteryl ethers in the adrenal glands, and to a lesser extent in the liver. The cholesteryl ethers selectively incorporate into plasma lipoproteins as determined by polyacrylamide gel electrophoresis.

partial inverse agonist. Finally we found that the functionality activity of the series of 1,2-dihydro-2-oxopyridine is controlled by the presence of a substituent in position 5 of the heterocyclic nucleus. In fact when the hydrogen atom in position 5 of the unsubstituted compound 1 was replaced with a phenyl group (compound 18) the CB2R activity was shifted from agonism to inverseagonism whereas
CB2R介导的治疗作用的相关性对于炎性和神经性疼痛以及神经退行性疾病的治疗是众所周知的。在我们寻找新的大麻素受体调节剂的过程中,我们报告了一系列作为CB2R配体的1,2-二氢-2-氧吡啶--3-羧酰胺衍生物的优化。尤其是,N-环庚基-5-(4-甲氧基苯基)-1-(4-氟苄基)-吡啶-2(1 H)-3-羧酰胺(17)具有很高的CB2R亲和力(K i = 1.0 nM) ,伴随着有趣的K i(CB1R)/ K i(CB2R)选择性比(SI = 43.4)。化合物17也被确定为有效的CB2R中性拮抗剂/弱部分反向激动剂。最后,我们发现,1,2-二氢-2-氧代吡啶系列的功能活性受杂环核5位上取代基的存在控制。在当在未取代的化合物的5位上的氢原子事实1用苯基(化合物代替18的CB2R活性从激动作用转移到反向激动作用而在相同位置引入)p -甲氧基苯基组导至化合物17其表现出作为CB2R中性拮抗剂/弱部分反向激动剂的行为。

acids. Various diaryl methane analogues can be prepared, including those with complex and biologically active motifs. The reactions proceed under transition-metal-free conditions, and C(sp2) halides, including aryl bromides and iodides, are unaffected. The orthogonal chemoselectivity is demonstrated in the streamlined synthesis of highly functionalized diaryl methane scaffolds using multi-halogenated substrates
