AbstractAn efficient, one‐pot method for the synthesis of dibenzodiazepinone derivatives involving copper‐catalyzed tandem CN bond formation is reported. The use of various halo amide and 2‐iodoaniline derivatives permitted the synthesis of an array of dibenzodiazepinone derivatives in moderate to good yields. Moreover, a dibenzodiazepinone derivative {2‐(11‐oxo‐5H‐dibenzo[b,e][1,4]diazepin‐10(11H)‐yl)benzonitrile} was utilized to synthesize the triazapentacyclic ring derivative {12‐chloro‐ 8,15,22‐triazapentacyclo[13.7.0.02,7.09,14.016,21]docosa‐1(22),2,4,6,9(14),10,12,16(21),17,19‐decaene}.magnified image

efficient palladium-catalyzed carbonylative cyclization of N-substituted 2-iodobenzamides and 2-iodoanilides was investigated for the synthesis of phthalimides and benzoxazinones, respectively, by usingphenylformate as a CO source. The present catalytic protocol circumvents the use of an expensive phosphine ligand as well as solvent in the case of the phthalimidesynthesis. Moreover, mild reaction conditions
通过使用甲酸苯酯作为 CO 源,研究了一种简单有效的钯催化的 N-取代 2-碘苯甲酰胺和 2-碘苯胺的羰基化环化反应,分别用于合成邻苯二甲酰亚胺和苯并嗪酮。本催化协议在邻苯二甲酰亚胺合成的情况下避免使用昂贵的膦配体以及溶剂。此外,温和的反应条件和对各种官能团的耐受性增强了该方法的普遍适用性。

coronavirus 2 (SARS-CoV-2), presents an urgent public health crisis. Without available targeted therapies, treatment options remain limited for COVID-19 patients. Using medicinal chemistry and rational drug design strategies, we identify a 2-phenyl-1,2-benzoselenazol-3-one class of compounds targeting the SARS-CoV-2mainprotease (Mpro). FRET-based screening against recombinant SARS-CoV-2 Mpro identified
一种新的冠状病毒——严重急性呼吸综合征冠状病毒2(SARS-CoV-2)的出现,提出了紧迫的公共卫生危机。如果没有可用的靶向治疗,COVID-19 患者的治疗选择仍然有限。使用药物化学和合理的药物设计策略,我们确定了针对 SARS-CoV-2 主要蛋白酶 (M pro )的 2-phenyl-1,2-benzoselenazol-3-one 类化合物。基于 FRET 的重组 SARS-CoV-2 M pro筛选确定了六种抑制蛋白水解的化合物,IC 50值为纳摩尔。预孵育稀释实验和分子对接确定了对 SARS-CoV-2 M pro的抑制作用可以通过共价或非共价机制发生,并确定铅 E04竞争性抑制 M pro 。铅 E24 以纳摩尔 EC 50值 (844 nM) 抑制 SARS-CoV-2 感染的 Vero E6 细胞中的病毒复制,并进一步证实会损害 SARS-CoV-2 在人肺上皮细胞和人诱导的多能干细胞中的复制-衍生的

Synthesis of substituted phenanthridinones and dibenzoazepinones has been realized from 2-halo-benzamides in the presence of potassium tert-butoxide and a catalytic amount of 1,10-phenanthroline or AIBN. This new carbon–carbon bond forming reaction gives direct access to various biaryl lactams containing six- and seven-membered rings chemoselectively. Carbon–carbon coupling seems to proceed by the generation

mechanism. A library of 15 2-alkyl-1,2-benzisoselenazol-3(2H)-ones was prepared. One member of the library was azide-containing derivative 1j that was competent to undergo a strain-promoted azide–alkyne cycloaddition. The library was evaluated for inhibition of Mycobacterium tuberculosis (Mtb) growth and Mtb Antigen 85C (Mtb Ag85C) activity. Compound 1f was most potent with a minimal inhibitory concentration
