  A new type of biopolymer-based heterogeneous catalyst, cellulose supported acidic ionic liquid (Cell-IL), which was developed earlier in our lab, has been found to be very effective for the regioselective synthesis of pyrazole based pyrido[2,3-d]pyrimidine-diones. Its regioselectivity was confirmed by 1H NMR spectroscopy. All the newly synthesized compounds were characterized by LC-MS, 1H NMR, 13C NMR, IR spectroscopy and elemental analysis. The newly synthesized compounds were evaluated for their in vitro antimalarial activity against Plasmodium falciparum, in vitro antitubercular activity against Mycobacterium tuberculosis H37Rv strain and also for their antibacterial activity against a panel of pathogenic strains of bacteria and fungi. Some of them exhibited excellent activity when compared with first line drugs.

  我们实验室早先开发的一种新型生物聚合物基异相催化剂--纤维素支撑的酸性离子液体（Cell-IL）被发现对吡唑基吡啶并[2,3-d]嘧啶二酮的区域选择性合成非常有效。1H NMR 光谱证实了它的区域选择性。所有新合成的化合物都通过 LC-MS、1H NMR、13C NMR、IR 光谱和元素分析进行了表征。对新合成的化合物进行了评估，以确定它们对恶性疟原虫的体外抗疟活性、对结核分枝杆菌 H37Rv 株的体外抗结核活性，以及对细菌和真菌致病菌株的抗菌活性。与一线药物相比，其中一些药物表现出卓越的活性。
