A series of novel pyrazole amide derivatives 3a–3p which take TMV PC protein as the target has been designed and synthesized by the reactions of 5-chloro-1-aryl-3-methyl-1H-pyrazole-4-carboxylic acids with 5-amino-1-aryl-1H-pyrazole-4-carbonitriles. All the compounds were characterized by 1H-NMR, mass spectroscopy and elemental analysis. Preliminary bioassays indicated that all the compounds acted against the tobacco mosaic virus (TMV) with different in vivo and in vitro modes at 500 μg/mL and were found to possess promising activity. Especially, compound 3p showed the most potent biological activity against tobacco mosaic virus (TMV) compared to ningnanmycin, and a molecular docking study was performed and the binding model revealed that the pyrazole amide moiety was tightly embedded in the binding sites of TMV PC (PDB code: 2OM3).

EC 2.2.1.6, also referred to as acetolactate synthase, ALS) has been considered as an attractive target for the design of herbicides. In this work, an optimized pyrazole sulfonamide base scaffold was designed and introduced to derive novel potential AHAS inhibitors by introducing a pyrazole ring in flucarbazone. The results of in vivo herbicidal activity evaluation indicates compound 3b has the most
To develop new antibacterial agents, a series of novel triazole-containing pyrazole ester derivatives were designed and synthesized and their biological activities were evaluated as potential topoisomerase II inhibitors. Compound 4d exhibited the most potent antibacterialactivity with Minimum inhibitory concentration (MIC) alues of 4 µg/mL, 2 µg/mL, 4 µg/mL, and 0.5 µg/mL against Staphylococcus aureus
为了开发新的抗菌剂,设计并合成了一系列新型含三唑的吡唑酯衍生物,并评估了它们作为潜在拓扑异构酶 II 抑制剂的生物活性。化合物 4d 表现出最有效的抗菌活性,对金黄色葡萄球菌、单核细胞增生李斯特菌、大肠杆菌和鸡沙门氏菌的最小抑菌浓度 (MIC) 为 4 µg/mL、2 µg/mL、4 µg/mL 和 0.5 µg/mL , 分别。体内酶抑制试验 4d 显示出最有效的拓扑异构酶 II (IC50 = 13.5 µg/mL) 和拓扑异构酶 IV (IC50 = 24.2 µg/mL) 抑制活性。进行分子对接以将化合物 4d 定位到拓扑异构酶 II 活性位点以确定可能的结合构象。总之,

A series of novel pyrazolo[3,4-b]pyridinederivatives were designed, synthesized, and biologically evaluated for anti-lung cancer activity. Structure–activity relationship and AutoGPA models were constructed based on the in vitro antiproliferative potency of the compounds against a human lung adenocarcinoma cell line (A549). Compound 9d exhibits improved potency for A549 cell growth inhibition (3.06 ± 0

The present invention is directed to a method for the synthesis of a bi-functional complex comprising a molecule part and an identifier oligonucleotide part identifying the molecule part. A part of the synthesis method according to the present invention is preferably conducted in one or more organic solvents when a nascent bi-functional complex comprising an optionally protected tag or oligonucleotide identifier is linked to a solid support, and another part of the synthesis method is preferably conducted under conditions suitable for enzymatic addition of an oligonucleotide tag to a nascent bi-functional complex in solution.
