A new series of cosalane analogues incorporating two fragments of the dichlorodisalicylmethane pharmacophore has been synthesized. In order to identify the position for the attachment of the pharmacophore fragments to the steroid ring that results in the most potent analogues, two types of compounds were designed. In the first type, the two pharmacophore fragments were attached at C-3 and C-17 of the steroid ring by using appropriate linker units. In the second type, both pharmacophore groups were connected to C-3 of the steroid through an alkenyl chain containing an amide moiety. All of the new compounds displayed antiviral activity versus HIV-1(RF), HIV-1(IIIB), and HIV-2(ROD) in cell culture. The relative potencies of the compounds resulting from the two attachment strategies were found to depend on the viral strain as well as the cell type, Overall, the attachment of the second pharmacophore did not result in either a large gain or a large loss in anti-HIV activity, and the results are therefore consistent with the hypothesis that the two pharmacophores act independently, and one at a time, with positively charged amino acid side chains present on the surface of gp120 and CD4.

The present invention relates to the use of SHIP1 inhibitors and pan-SHIP1/2 inhibitors in various methods, including, without limitation: (i) a method to treat obesity or reduce body fat of an obese subject; (ii) a method to limit bone development in a subject suffering from an osteopetrotic or sclerotic disease; (iii) a method to treat or prevent diabetes; (iv) a method to reduce glucose intolerance or insulin resistance; and (v) a method to lower cholesterol.

Introduction of an amido group or an amino moiety into the alkenyl linker chain of cosalane (1) provided a newseries of analogues 3-8. The new compounds were evaluated as inhibitors of the cytopathic effect of HIV-1 and HIV-2 in cell culture. The replacement of the 1' and 2' carbons in the linker chain of I by an amido group was generally tolerated. The length of the linker chain and the stereochemistry
将氨基或氨基部分引入到al草烷(1)的烯基连接链中提供了一系列新的类似物3-8。新化合物被评估为在细胞培养物中抑制HIV-1和HIV-2的细胞病变作用。通常容许I的连接链中的1'和2'碳被酰胺基取代。连接链的长度和甾族环C-3处取代基的立体化学对抗病毒活性和效价都有重要影响。将氨基部分结合到接头中完全消除了抗HIV活性。在HIV复制周期中有几个步骤被提议作为治疗剂开发的目标(De Clercq,EJ Med。Chem。1995,38,2491; De Clercq,E.Pure Appl.Chem。1998,70, 567)。然而,当前批准的抗HIV药物仅针对病毒酶逆转录酶或蛋白酶(Carpenter。CCJ; MA菲斯切尔; SM汉默; Hirsch女士; DM雅各布森; DA; Katzenstein; JSG Montaner; DD里奇曼;密苏里州萨格(Saag);密歇根州Scho
