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。
In this paper, a concise, open-vessel synthesis of 1-arylisoquinolines is described via HCl-mediated intermolecular cyclocondensation of oxygenated arylacetic acids with arylaldehydes in the presence of NH2OH and alcoholic solvents under mild and one-pot reaction conditions. A plausible mechanism is proposed and discussed herein. In the overall reaction process, only water was generated as the byproduct
Twenty-nine novel triazole analogues of ravuconazole and isavuconazole were designed and synthesized. Most of the compounds exhibited potent in vitro antifungal activities against 8 fungal isolates. Especially, compounds a10, a13, and a14 exhibited superior or comparable antifungal activity to ravuconazole against all the tested fungi. Structure-activity relationship study indicated that replacing
Synthesis and in vitro biological evaluation of novel coumarin derivatives containing isoxazole moieties on melanin synthesis in B16 cells and inhibition on bacteria
novel series of coumarin derivatives 6a-o, bearing isoxazolemoieties were designed and synthesized. After that, they were evaluated for melanin synthesis in murine B16 cells and inhibitory effect on the growth of CA (Candida albicans), EC (Escherichia coli), SA (Staphylococcus aureus). It was found that eleven compounds (6b-f, 6j-o) showed a better activity on melanin synthesis than positive control
Discovery of Natural Product‐Based Fungicides (II): Semisynthesis and Biological Activity of Sarisan Attached 3‐Phenylisoxazolines as Antifungal Agents
the discovery and development of naturalproducts‐basedfungicides, a series of thirty‐one sarisan attached 3‐phenylisoxazolines were synthesized and evaluated for their antifungalactivities against five phytopathogenic fungi (B. cinerea, C. lagenarium, A. solani, F. solani, and F. graminearum). Among all title sarisan derivatives, compounds IV2, IV14 and IV23 showed potent antifungalactivity against
