357649-93-5

以2-亚环戊基肼-1-硫代甲酰胺和α-溴代-4-氯苯乙酮为原料合成4-(4-氯苯基)-2-(2-环戊基亚基肼基)噻唑的一般步骤：准确称取0.157 g环戊酮缩氨基硫脲席夫碱和0.234 g对氯-α-溴苯乙酮，置于反应瓶中，加入15 mL异丙醇作为溶剂。在室温下搅拌反应混合物，并通过薄层色谱（TLC，展开剂比例为乙酸乙酯：石油醚=1：2）监测反应进程。反应4小时后，观察到反应体系无明显变化，遂终止反应。将反应混合物过滤，所得滤饼用乙醇洗涤，最终获得0.271 g白色固体产物。

体外研究

CPTH2 (100 μM; 12, 24, 48 hours) causes a decrease in cell proliferation after as early as 12 h with a further significant reduction after 48 h stimulation.
CPTH2 (100 μM; 12 or 48 hours) causes a comparable drop of the activity in both cell lines.
CPTH2 (100 μM; 48 hours) produces a drastic increase in apoptotic/dead cell population after 48 h.
CPTH2 (100 μM; 12, 24, 48 hours) shows a reduced acetylation of both global AcH3 histone and H3AcK18.
CPTH2 (100 μM; 24, 48 hours) is capable to counteract invasion and migration of ccRCC-786-O cells in culture.
CPTH2 (0.2, 0.5, 1 mM) inhibits the growth of a GCN5 deleted strain and a single catalytic mutant E173H.
