  The present invention provides a method useful in the diagnosis and monitoring of cancer wherein there is an abnormal expression of PBR. The method of the invention is particularly useful in evaluating the severity of the cancer, e.g. PBR expression correlates with cell proliferation rates, metastatic potential, tumor aggressiveness, malignancy progression. The method of the invention can therefore be applied in the determination of likely disease progression and in making an associated prognosis. Furthermore, the method of the invention can find use in determining the likely success of certain therapeutic approaches, or in the evaluation of the efficacy of certain proposed new treatments.

  本发明提供了一种在癌症的诊断和监测中有用的方法，其中PBR的表达异常。本发明的方法特别适用于评估癌症的严重程度，例如PBR表达与细胞增殖率、转移潜力、肿瘤侵袭性、恶性进展相关。因此，本发明的方法可以应用于确定可能的疾病进展，并作出相关的预后。此外，本发明的方法可以用于确定某些治疗方法的成功可能性，或评估某些提议的新治疗方法的有效性。

  Effective preparation of olivacine and ellipticine via late-stage D-ring cyclization is described. Key features of the synthetic routes include trifluoroacetic acid-mediated formation of a lactone that is fused to a tetrahydrocarbazole derivative and its one-pot two-step ring opening and aromatization mediated by para-toluenesulfonic acid and palladium on carbon, respectively.

  pathway inhibition on tumor growth, we set out to find small-molecule inhibitors of TNKS/TNKS2 with suitable drug-like properties. Starting from 1a, a high-throughput screening hit, the spiroindoline derivative 40c (RK-287107) was discovered as a potent TNKS/TNKS2 inhibitor with >7000-fold selectivity against the PARP1 enzyme, which inhibits WNT-responsive TCF reporter activity and proliferation of human

  经典的WNT途径在癌症发病机理中起重要作用。据报道，抑制端粒聚合酶（TNKS / TNKS2）的聚（ADP-核糖）聚合酶催化活性可通过防止AXIN（Wnt /β的负调节剂）的多聚ADP-核糖基化依赖性降解来降低Wnt /β-catenin信号。 -catenin信号传导。为了研究tankyrase和Wnt途径抑制对肿瘤生长的影响，我们着手寻找具有类似药物性质的TNKS / TNKS2小分子抑制剂。从1a开始，它是一种高通量筛选命中物，螺环丝氨酸衍生物40c（RK-287107）被发现是一种有效的TNKS / TNKS2抑制剂，对PARP1酶的选择性> 7000倍，从而抑制了WNT响应的TCF报道分子的活性和增殖。人结肠直肠癌细胞系COLO-320DM的制备。在小鼠异种移植模型中，RK-287107还显示出剂量依赖性的肿瘤生长抑制作用。这些观察结果表明，RK-287107是一种有前途的先导化
