An improved procedure for the preparation of arylthioureas consists of the reaction of benzoyl isothiocyanate with anilines in acetone and debenzoylation of the resultant N-aryl-N′-benzoylthioureas with 5% aqueous sodium hydroxide. Bicycloalkylthioureas and N-(arylalkyl)thioureas (e.g., 9H-9-fluorenylthiourea) are directly prepared from the corresponding isothiocyanates and ammonia.

Some new 4-2-[(aryl) amino]-1,3-thiazol-4-yl}benzene-1,2-diols are prepared and characterized by spectral analysis. The newly prepared compounds are studied for their antibacterial and antifungal activity. Interestingly, almost all the compounds are found to possess promising antibacterial and antifungal activity against all tested microorganisms.
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
