吲哚胺2,3-二加氧酶1(IDO1)是几种病理状况,尤其是癌症的免疫调节中的有希望的目标。在这里,我们目前与新型异恶唑并[5,4 - d ]嘧啶-4(5 H)-一个支架的一系列IDO1抑制剂的合成。使用6步或7步合成程序制备了一个有针对性的文库,以系统地研究所述支架的构效关系。化学驱动的修改导致我们我们具有最佳的类抑制剂的发现p三氟甲基(23),p -环己基(32),或p甲氧基羰基(20,39)IC 50值在低微摩尔范围内的取代苯胺部分。除hIDO1以外,还测试了化合物对吲哚胺2,3-双加氧酶2和色氨酸双加氧酶的抑制作用,发现它们对hIDO1具有选择性。因此,我们的结果证明了对IDO1选择性异恶唑并[5,4- d ]嘧啶4(5 H)-one抑制剂的成功研究,它定义了一种有前途的化学探针,并带有用于进一步开发强效小分子免疫调节剂的新型支架。

Compounds of formula (I) wherein R is hydrogen, lower alkyl, (C3-C8)cycloalkyl, hydroxy, halo, lower alkoxy, trifluoromethoxy, trifluoromethyl or cyano; and A is biaryl, optionally substituted β-naphthyl, bicyclic heterocyclic aryl, (C3-C6)cycloalkylmonocyclic carbocyclic aryl, or (C5 or C6)cycloalkane fused-monocyclic carbocyclic aryl; pharmaceutically acceptable salts thereof, and pharmaceutically acceptable esters thereof; which are useful for the treatment of COX-2 dependent disorders.
Here we present the synthesis of a series of IDO1 inhibitors with the novel isoxazolo[5,4-d]pyrimidin-4(5H)-one scaffold. A focused library was prepared using a 6- or 7-step synthetic procedure to allow a systematic investigation of the structure-activity relationships of the described scaffold. Chemistry-driven modifications lead us to the discovery of our best-in-class inhibitors possessing p-trifluoromethyl

Synthesis of New Benzoxazinone Derivatives as Neuropeptide Y5 Antagonists for the Treatment of Obesity
NPY Y5 receptor and showing functional antagonism in the forskolin-induced cyclic AMP test. Prelimminary studies in order to understand the structure-activityrelationship were undertaken. Selected compounds were further evaluated for in vivo efficacy, affording the lead compound 2-[4-(8-methyl-2-oxo-4H-benzo[d][1,3]oxazin-1-yl)piperidin-1-yl]-N-(9-oxo-9H-fluo ren-3-yl)acetamide 5p, which displayed
