The interaction of the chemokine receptor CXCR4 with its ligand CXCL12 is involved in many biological processes such as hematopoesis, migration of immune cells, as well as in cancer metastasis. CXCR4 also mediates the infection of T-cells with X4-tropic HIV functioning as a coreceptor for the viral envelope protein gp120. Here, we describe highly potent, selective CXCR4 inhibitors that block CXCR4/CXCL12 interactions in vitro and in vivo Lis well as the infection of target cells by X4-tropic HIV.

nonkaliuretic diuretic in rats. The diuretic profile of 1 and its 1-adamantyl analog (U-37883A, 4) was confirmed orally in dogs, when they were less potent than standard diuretics but showed furosemide-like natriuresis at > or = 100 mumol/kg. However, acute 1 at 61 and 90 mumol/kg iv resulted in lethal cardiac toxicity in dogs. Many analogs of 1 exhibited qualitatively similar diuretic profiles, but
随机筛选确定N,N'-二环己基-4-吗啉羧box(U-18177,1)为大鼠口服有效的非利尿剂利尿剂。在狗中口服1和其1-金刚烷基类似物(U-37883A,4)的利尿特性时,它们的功效不如标准利尿剂,但在>或= 100 mumol / kg时显示了速尿类似的利尿作用。但是,急性1在61和90 mumol / kg iv静脉注射可导致犬致命的心脏毒性。1的许多类似物在质上表现出相似的利尿特性,但没有一个足以保证发育。化合物1还逆转了米诺地尔在犬中的血管舒张作用,这导致了血管相互作用的研究表明,类似物4可能会阻断ATP敏感的K通道。这种钾通道阻滞机制可能有助于该系列的利尿活性。
