Preliminary hit-to-lead optimization of a novel series of phenylsulfonyl hydrazide derivatives, which were derived from the high throughput screening hit compound 1 (IC50 = 5700 nM against PGE(2) production), for a potent suppressor of PGE(2) production is described. Subsequent optimization led to the identification of the potent lead compound 8n with IC50 values of 4.5 and 6.9 nM, respectively, against LPS-induced PGE(2) production and NO production in RAW 264.7 macrophage cells. In addition, 8n was about 30- and > 150-fold more potent against mPGES-1 enzyme in a cell-free assay (IC50 = 70 nM) than MK-886 and hit compound 1, respectively. Molecular docking suggests that compound 8n could inhibit PGE2 production by blocking the PGH(2) binding site of human mPGES-1 enzyme. (C) 2015 Elsevier Ltd. All rights reserved.

conditions, which favor either of two regioisomers. One regioisomer corresponds to a kinetic product (7a–7c) and the other regioisomer corresponds to a thermodynamic product (8a–8c). Among them, the structure of kinetic product 7b was confirmed by measuring single X-ray crystallography. In vitro PGE2 assay studies showed that the kinetic product (7a and 7b; IC50 = 0.69 and 0.55 μM against PGE2) is generally
Utilization of transition metal fluoride-based solid support catalysts for the synthesis of sulfonamides: carbonic anhydrase inhibitory activity and <i>in silico</i> study
The applications of solid support catalysts in catalyzing organic reactions are well-evident. In the present study, we explored a transition metal fluoride (FeF3) adsorbed on molecularsieves (4 Å) as a solid support catalyst for the preparation of sulfonamides 3a–3o. The solid support catalyst was characterized via X-ray diffraction and AFM analysis. The catalyst was further explored for the synthesis
固体载体催化剂在催化有机反应中的应用是显而易见的。在本研究中,我们探索了一种吸附在分子筛(4 Å)上的过渡金属氟化物(FeF 3 )作为制备磺胺类药物3a-3o的固体载体催化剂。通过X 射线衍射和 AFM 分析对固体载体催化剂进行了表征。进一步探索了该催化剂用于合成吲哚6a-h、1H-四唑和 1,4-二氢吡啶。研究了本文制备的磺胺类药物抑制碳酸酐酶(hCA II、hCA IX 和 hCA XII)的潜力。发现所有化合物都是具有 IC 50的活性抑制剂在低微摩尔范围内的值。有些化合物甚至被发现是高度选择性的抑制剂。化合物3i仅抑制 hCA II (IC 50 = 2.76 ± 1.1 μM) 并且对 hCA IX 和 hCA XII 具有 <27% 的抑制作用。类似地,3e (IC 50 = 0.63 ± 0.14 μM) 仅抑制 hCA XII,对 hCA II 和 hCA IX 的抑制
