摘要 甲芬那酸钠、钾和钙盐的通式为 [Na(mef)(H 2 O) 2 ] n · n H 2 O, [K(mef)(H 2 O)] n 和 [Ca(mef) ) 2 (H 2 O) 2 ] n·n H 2 O 已合成,通过 X 射线晶体学、 1 H 和 13 C NMR 和红外光谱研究。复合盐在空气中稳定且可溶于水。在加热过程中,Na 和 K 络合物在络合水中熔化,然后以无水形式重结晶。在固态下,所有的盐都会产生一维配位聚合物。Na、K 和 Ca 配合物的中心原子分别为 5、6 和 7 个配位原子。在所有结构中都存在OH⋯O、NH⋯O和CH⋯O氢键。在实验结果和量子力学计算的基础上,对甲芬那酸及其三配位高分子化合物进行了振动分析。理论和实验振动频率相似,并揭示了所有 IR 有源振荡器的特征振动。在盐的红外光谱中,在约 羧酸根基团的典型值为 1365 和 1600 cm -1。

A new series of coordination polymers (CPs) were synthesized and crystallographically characterized by single-crystal X-ray diffraction with the aim of developing drug-delivery systems via metallogel formation. Structural rationale was employed to design such coordination-polymer-based metallogels. As many as nine CPs were obtained by reacting two bis(pyridyl)urea ligands, namely, 1,3-dipyridin-3-ylurea
Metallogelators/metallogels derivedfrom a series of multi-NSAID-based Zn(II)-coordination complexes displaying anti-cancer and anti-bacterial properties were designed based on a structural rationale as plausible multi-drug self-delivery systems.
Metallogelators /metallogels 衍生自一系列基于多 NSAID 的 Zn( II )-配位配合物,显示出抗癌和抗菌特性,是基于结构原理设计的,作为合理的多药物自我递送系统。

Anthranilic acid ester derivatives having the general formula (I): ##STR1## wherein R represents as alkyl group having 1 to 3 carbon atoms substituted with a pyridyl group or a furanmethyl group. These anthranilic acid ester derivatives have a remarkable antiinflammatory and analygetic effect and a high endermic permeability and, therefore, is suitable for use as an antiinflammatory and analgetic agent.
Background:The free carboxylicacid group present in the mefenamic acid (MFA) structure plays a potential role in developing various neuromuscular side effects after MFA administration. In this study, the hydroxypropyl promoiety was added to the carboxylicacid group of MFA in an attempt to reduce the neuromuscular side effects of MFA and improve its therapeutic effects.Methods:Hydroxypropylester of
