children with acutemyeloidleukemia (AML), conferring a poor prognosis in both age groups. In an in vivo setting, 27e strongly inhibited the growth of a FLT3-ITD-positive AML human tumor xenograft (MV4–11) following oral administration, with in vivo biomarker modulation and plasma free drug exposures consistent with dual FLT3 and Aurora kinase inhibition. Compound 27e, an orally bioavailable dual FLT3 and
对基于咪唑并[4,5 - b ]吡啶的系列极光激酶抑制剂进行优化,鉴定出 6-chloro-7-(4-(4-chlorobenzyl)pirazin-1-yl)-2-(1, 3-dimethyl-1 H -pyrazol-4-yl)-3 H -imidazo[4,5- b ]pyridine ( 27e ),一种强效的 Aurora 激酶抑制剂 (Aurora-A K d = 7.5 nM, Aurora-B K d = 48 nM)、FLT3 激酶 ( K d = 6.2 nM) 和 FLT3 突变体,包括 FLT3-ITD ( K d = 38 nM) 和 FLT3(D835Y) ( K d = 14 nM)。FLT3-ITD 引起组成型 FLT3 激酶激活,在 20-35% 的成人和 15% 的急性髓性白血病 (AML) 患儿中检测到,这两个年龄组的预后都很差。在体内环境中,27e在口服给药后强烈抑制FLT3
Design, synthesis and antiproliferative activity studies of 1,2,3-triazole–chalcones
3-triazole–chalcone hybrids were designed, synthesized and evaluated for their antiproliferative activity against three selected cancer cell lines (SK-N-SH, HepG-2 and MGC-803). Most of the synthesized compounds exhibited moderate to good activity against all the cancer cell lines selected. Particularly, compound 12k showed the most excellent antiproliferative activity with an IC50 value of 1.53 μM against

Novel fluorophenyl tethered thiazole and chalcone analogues as potential anti-tubercular agents: Design, synthesis, biological and in silico evaluations
Novel analogues of fluorophenyl tethered thiazoles 7a-k and chalcones 10a-k were designed through molecular hybridization approach. All the synthesized final compounds were evaluated for their in vitro antimycobacterial activity against M. tuberculosis H37Rv strain. Among the two series, compound 10g displayed potent inhibition with MIC99 of 1.56 µM against parental and isoniazid-resistant strains
通过分子杂交方法设计了氟苯基栓系噻唑7a-k和查耳酮10a-k的新型类似物。评估了所有合成的最终化合物对结核分枝杆菌H 37 Rv 菌株的体外抗分枝杆菌活性。在这两个系列中,化合物10g显示出对结核分枝杆菌的亲代和异烟肼耐药菌株的有效抑制作用,MIC 99为 1.56 µM 。此外,相同的化合物抑制细胞内结核分枝杆菌的生长。为了深入了解作用的分子机制,in silico使用 DNA 促旋酶的分子结构进行了分子对接实验,揭示了关键的相互作用。通过分枝杆菌 DNA 促旋酶蛋白对先导化合物10g和参比药物(CFX-环丙沙星)的分子动力学模拟研究进一步证实了这一点。此外,根据 Lipinski 五法则和 ADME 药代动力学参数计算合成化合物的药物似然性。因此,在我们的研究中鉴定出基于查尔酮的铅10g,并显示出具有药物样特性的有前途的抗结核活性。鉴定出的先导分子可以作为开发针对亲本和耐药结核菌株的新型强效抗结核药物的起点。
