Aliphatic and aromatic nitriles react with thioacetic acid in the presence of calcium hydride to give the corresponding thioamides in good to excellent yields. The examples studied include haloaryl nitriles in which the halogen is facile towards S N Ar reactions under other conditions.
脂肪族和芳香族腈在氢化钙存在下与硫代乙酸反应,以良好到极好的收率得到相应的硫代酰胺。研究的例子包括卤代芳基腈,其中卤素在其他条件下容易发生 SN Ar 反应。
Identification of Thiazoyl Guanidine Derivatives as Novel Antifungal Agents Inhibiting Ergosterol Biosynthesis for Treatment of Invasive Fungal Infections
antifungal agents, which inhibit a novel target enzyme in the ergosterolbiosynthesis pathway. Structure–activity relationship development and property optimization by reducing lipophilicity led to the discovery of 6h, which showed potent antifungal activity against Aspergillus fumigatus in the presence of serum, improved metabolic stability, and PK properties. In the murine systemic A. fumigatus infection
侵袭性真菌感染 (IFIs) 是致命的感染,但治疗选择有限。由于副作用、药物相互作用、不利的药代动力学特征和新出现的耐药真菌,现有药物的临床疗效并不令人满意。因此,开发具有新机制的抗真菌药物是当务之急。在此,我们报告了新型芳基胍抗真菌剂,其抑制麦角甾醇生物合成途径中的新型靶酶。通过降低亲脂性的构效关系发展和性质优化导致了6h的发现,其在血清存在下显示出对烟曲霉的有效抗真菌活性,提高了代谢稳定性和 PK 特性。在小鼠全身A. fumigatus感染模型,6 小时表现出与伏立康唑相当的抗真菌功效 ( 1e )。此外,由于麦角甾醇生物合成途径中新靶点的抑制作用,6h显示出对耐唑类烟曲霉的抗真菌活性。
Design, synthesis and biological evaluation of novel hydrogen sulfide releasing capsaicin derivatives
CAP and alleviating its irritating effects, a series of H2S-releasing CAPs were designed and synthesized by combining capsaicin and dihydro capsaicin with various hydrogensulfide donors. The resulting compounds were evaluated their TRPV1 agonist activity, analgesic activity, anticancer activities, H2S-releasing ability, and gastric mucosa irritation. Biological evaluation indicated that the most active

Retinoids are a class of synthetic and natural compounds structurally related to retinoic acid. In a search for discovery of a new class of heterocycle‐bridged and conformationallyconstrainedretinoids, here we report the synthesis of 4‐(7,8,9,10‐tetrahydro‐7,7,10,10‐tetramethyl‐4H‐benzo[6,7]chromeno[4,3‐d]thiazole‐2‐yl)benzoicacid (10) starting from 5,6,7,8‐tetrahydro‐5,5,8,8‐tetramethylnaphthalen‐2‐ol
类视黄醇是一类在结构上与视黄酸有关的合成和天然化合物。在一个新的类杂环桥和构象受限的类维生素的发现搜索,在这里我们报告的4-(7,8,9,10四氢7,7,10,10四甲基合成4 ^ h -从5,6,7,8-四氢-5,5,8,8-四甲基萘-2-酚开始的苯并[6,7] chromeno [4,3 - d ]噻唑-2-基)苯甲酸(10) (13)。尝试了几种方法以获得目标化合物10。在元素分析和光谱数据(1 H NMR,IR和MS)的基础上,对合成化合物的结构进行了阐明。
