The addition of hydrazine to functionalizedfurans 2a–d leads to a variety of 4,4′-bipyrazoles 4a–c depending on the structure of the starting materials. In one example, compound 2c was first converted to an intermediate, furo[3,4-d]pyridazine 3c which was then transformed into 4,4′-bipyrazole 4c on reacting with hydrazine.
根据原料的结构,将肼添加到官能化的呋喃2a - d中可生成各种4,4'-联吡唑4a - c。在一个实施例中,首先将化合物2c转化为中间体呋喃并[3,4- d ]哒嗪3c,然后与肼反应将其转化为4,4'-联吡唑4c。

inhibition of the EGFR enzymatic activity with IC50 = 1.53 μM and 90% inhibition at 10 μM concentration. In silico investigation predicts the possibility of direct binding between the new coumarin–furo[2,3-d]pyrimidone hybrid molecules and the EGFR. The results suggest that coumarin–furo[2,3-d]pyrimidone hybrid molecules are potential antitumor agentstargeting human liver cancer cells.
报道了一些香豆素-呋喃并[2,3- d ]嘧啶酮杂化分子的设计、合成和抗肿瘤活性研究。在体外,使用 HepG2 细胞研究6a-n和10a-n的细胞毒性。结果表明,通过酰肼连接体将呋喃嘧啶酮支架与香豆素偶联可以有效提高它们的协同抗癌活性。香豆素-呋喃并[2,3- d ]嘧啶酮组合10a对HepG2细胞表现出显着的抑制活性,IC 50 = 7.72 ± 1.56 μM,优于吉非替尼和索拉非尼。值得一提的是,香豆素-呋喃并[2,3- d ]嘧啶酮组合10a对EGFR酶活性表现出优异的抑制作用,IC 50 = 1.53 μM,在10 μM浓度下抑制率为90%。计算机研究预测新的香豆素-呋喃并[2,3- d ]嘧啶酮杂合分子与 EGFR 之间直接结合的可能性。结果表明,香豆素-呋喃并[2,3- d ]嘧啶酮杂合分子是针对人类肝癌细胞的潜在抗肿瘤剂。
