between trigonal bipyramidal and square pyramidal. The antileishmanialactivity was assessed against Leishmania tropica KWH23, and also human macrophages were used to measure the cytotoxicity of these complexes. The IC50 of the antimonials 1–9 indicates their efficaciousness as compared with the standard antimonial drug used. The significant activity of complex 1 assumes that greater multitude of interactions
在追求安全的药物候选的寄生疾病如利什曼病,一系列所述类型的杂五价锑的[R的处理3的Sb(O 2 CR')2 ](1 - 9)已经被合成,并使用元素分析( CHN),傅里叶变换红外光谱和多核(1 H和13 C)NMR光谱。研究的羧酸盐主要是取代的苯甲酸酯,带有一些具有乙酰或尼古丁配体的配合物。[Sb(C 6 H 5)3(o -NH 2 C 6 H[4 COO)2 ](1)和[Sb(C 6 H 5)3(3,5-Cl 2 C 6 H 3 COO)2 ](4)被确定为基本上具有Sb(V)中心的单体,并显示采用介于三角形双锥体和正方形锥体之间的几何形状。评估了抗热带利什曼原虫KWH23的抗菌活性,并且还使用人类巨噬细胞来测量这些复合物的细胞毒性。锑1 – 9的IC 50表示与使用的标准锑药相比,它们的功效。配合物1的显着活性假定大量的相互作用是抗刀刃活性增强的原因。细胞毒性结果表明,即使在低浓度下,

compounds have the general formula [Cr2(R1-deaH)2(O2CR2)Cl2]Cl where R1 = Me and R2 = H (1), Me (2), CMe3 (3), Ph (4), 3,5-(Cl)2Ph (5), (Me)5Ph (6), R1 = Et and R2 = H (7), Ph (8). The compound [Cr2(Me-deaH)2Cl4] (9) was synthesised in order to study the effect of removing/adding the carboxylate bridge on the observed magnetic behaviour. Direct current (DC) magnetic susceptibility measurements showed ferromagnetic

A new calix[4]arene-supported MnIIIMnII cluster, formed by the introduction of 3,5-dichlorobenzoate to a system known to afford MnIII2MnII2 Single-Molecule Magnets (SMMs), assembles in a layered manner through halogen interactions; structural and magnetic properties of this new cluster are presented.

Two series of twenty diversely substituted benzothiazole amides were designed and synthesized aiming to obtain derivatives with potential anti-inflammatory activity and decreased GIT ulceroginicity. All the synthesized compounds were in-vivo screened for their anti-inflammatory activity using carrageenan induced rat hind paw edema model. Results revealed that compounds 3h and 6a were the most potent
