Tubulin-targeting drugs have increasingly become the focus of anticancer drugs research. Twenty-five novel benzimidazole grafted benzsulfamide-containing pyrazole ringderivatives were synthesized and evaluated for bioactivity as potential tubulin polymerization inhibitors. Among them, compound 30 showed the most excellent inhibition against tubulin assembly (IC50 = 1.52 μM) and in vitro growth inhibitory

A series of novelthiazolo pyrimidine derivatives were designed, synthesized, and assessed for their in vitro anti‐mycobacterial activities. All hybrids displayed considerable antitubercular activities against primary Mycobacterium smegmatis mc2 155 screening and successive Mycobacterium tuberculosis H37Rv. In particular, the hybrid entities 13 and 14 (minimum inhibitory concentration: 47 and 39 μg/mL)
An efficient synthetic route to construct ortho-substituted 1-phenyl-1H-pyrazole-4carboxaldehydes and the correspondingethanones starting from 1-phenyl-1H-pyrazol-3-ol is described. Carbon-carbon bond-forming Pd-catalysedcross-couplingreactions were applied for the functionalisation of the intermediate pyrazole triflates. Detailed NMR spectroscopic investigations were undertaken with all obtained

structure–activity relationship suggested that the variation in the inhibitory activities of the compounds affected by different substitutions on phenyl rings of diphenyl pyrazole moiety. The enzyme kinetic studies of the most potent compound 9i revealed that it inhibited α-glucosidase in a competitive mode with a Ki of 56 μM. Molecular docking study was performed to predict the putative binding interaction. As expected

target for the development of new antibacterial agents. We present here the discovery of a promising new series of Pyrazol-Benzimidazole amides with low toxicity and potent FabH inhibitory. Twenty-seven novel compounds have been synthesized, and all the compounds were characterized by 1H NMR, 13C NMR and MS. Afterwards they were evaluated for in-vitro antibacterial activities against E. coli, P. aeruginosa
FabH酶催化脂肪酸生物合成的第一步,这对于细菌的生存至关重要。因此,FabH已被确定为开发新型抗菌剂的有吸引力的靶标。我们在这里提出了一种有前景的,具有低毒性和强效FabH抑制作用的吡唑-苯并咪唑酰胺新系列的发现。合成了27种新型化合物,所有化合物均通过1 H NMR,13 C NMR和MS表征。之后,评估它们对大肠杆菌,铜绿假单胞菌,枯草芽孢杆菌和金黄色葡萄球菌以及大肠杆菌的体外抗菌活性。FabH抑制和细胞毒性测试。一些化合物被证明是低毒性的和有效的,特别是化合物31表现出最有潜力与针对所测试的细菌菌株0.49-0.98微克/毫升的MIC和IC一种新的药物50的1.22 μ中号针对大肠杆菌的FabH。八个类似物16,28,30,31,33,34,35和36与对野生型低范围MIC黄单胞菌表现出对FabH缺陷型突变株没有抑制作用,这坚定地证明了通过与FabH相互作用达到抗菌活性的化合物类
