First Entry to [4+2] Cycloadditions Involving 5-Amino-2-furanmethanols
摘要:
The preparation of new 5-amino-2-furanmethanols bearing various amino and primary or secondary alcohol groups is described. The structures of 5-amino-2-furanmethanols as dienes are consistent with (1)H NMR data and cyloadditions of them allows the selective synthesis of tetrasubstituted aminobenzylic alcohols, amino phenols or lactones through Diels-Alder reactions.

Provided herein are non-peptide GLP-1 receptor modulator compounds, for example, of Formula (I), pharmaceutical compositions comprising such compounds, and processes of preparation thereof. Also provided are methods of their use for the treatment of a metabolic disorder.
β-Alkylation of amino-furan and -thiophene heterocycles is described through metal-, acid- and base-free carbon–carbon bond formation. The ability of both heterocycles to undergo selective β-alkylation is compared by mean of experimental and theoretical data. The presence of chiral amine substituents induced the diastereoselective generation of the newly formed additional stereocenter.
diseases especially cancer, thus highlighting the utmost significance of the development of small molecule inhibitors against this potential therapeutic target. In the present study, through virtual screening and iterative optimization, we identified DCH36_06 as a bona fide, potent p300/CBP inhibitor. DCH36_06 mediated p300/CBP inhibition leading to hypoacetylation on H3K18 in leukemic cells. The suppression
组蛋白乙酰转移酶(HATs)通过优先使组蛋白上赖氨酸残基的ε-氨基乙酰化来缓解转录抑制。HAT的失调与几种疾病(尤其是癌症)的病因密切相关,因此突出了开发针对该潜在治疗靶点的小分子抑制剂的最重要意义。在本研究中,通过虚拟筛选和迭代优化,我们将DCH36_06鉴定为真正有效的p300 / CBP抑制剂。DCH36_06介导的p300 / CBP抑制导致白血病细胞中H3K18的低乙酰化。p300 / CBP活性的抑制可阻止几种白血病细胞系中的细胞增殖。此外,DCH36_06在G1期阻止了细胞周期,并通过激活capase3诱导了细胞凋亡,caspase9和PARP阐明了其抗增殖活性的分子机制。在转录组分析中,DCH36_06改变了下游基因表达,并通过实时PCR验证了凋亡通路相关基因。重要的是,DCH36_06阻断了小鼠白血病异种移植物的生长,从而支持了其潜在的抗癌作用。体内使用为p300 / C
