Pyrimidinedione derivatives of the formula: ##STR1## wherein R.sup.1 and R.sup.2 is so linked with each other as to make an alkylene chain and thus form a heterocyclic structure, A, R.sup.3, R.sup.4, X.sup.1, X.sup.2 and X.sup.3 are substituents, respectively, and n is 2 or 3 have a basic backbone in which a phenyl group part and a pyrimidinedione part are linked by a structure comprising an alkyl chain and a heterocyclic ring having two nitrogen atoms. These compounds are useful for a medical treatment of cardiac arrhythmias.

possible dual acting ligands, selected compounds were tested for antioxidant properties. Compound 16 (hH3R Ki = 592 nM) showed the strongest antioxidant properties at the concentration of 10−4 mol/L. It significantly reduced the amount of free radicals presenting 50–60% of ascorbic acid activity in the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, as well as showed antioxidative properties in the ferric reducing
为了找到新的双重作用的组胺H 3受体(H 3 R)配体,我们在结构上基于先前在我们小组中描述的结构,设计了一系列高活性和选择性的人组胺H 3受体(hH 3 R)。配体KSK63。结果,获得的15种化合物显示出中等的hH 3 R亲和力,最好的是化合物17(hH 3 R K i = 518 nM)。与组胺H 3对接R同源性模型揭示了两种可能的结合模式,在两种情况下都保留了关键的相互作用。为了找到可能的双作用配体,测试了所选化合物的抗氧化性能。化合物16(hH 3 R K i = 592 nM)在10 -4 mol / L的浓度下显示出最强的抗氧化性能。在2,2-二苯基-1-吡啶并肼基(DPPH)分析中,它显着减少了抗坏血酸活性的50-60%的自由基数量,在三价铁还原抗氧化剂能力(FRAP)分析中显示了抗氧化性能。尽管尚不知道抗氧化机制和适度的hH 3 R亲和力,16(QD13)构成了寻找潜在的双重作用的H

A series of surface attached silane or benzophenone sulfonamide quaternary ammonium antimicrobials show potent efficacy at solid/air and solid/liquid interfaces.
The magnetic field effects (MFE) on the lifetimes of tripletbiradicals generated from the intramolecular photoreaction of bifunctional chain molecules, α-(4-benzoylphenoxy)-ω-[4-(phenylamino)phenoxy]alkanes (BP–O–n–O–DPA, n=2–16) were studied by laser flash photolysis. MFE on the biradicallifetimes are strongly affected by magnetic field, chain length, and solvent. The effects are interpreted in

behavior with several of the more effective novel oximes, but not 2-PAM. Therefore these novel oximes have demonstrated an ability to reactivate inhibited ChE in brain preparations from two species and in vivo data support their ability to enter the brain and provide a therapeutic action. These novel oximes have the potential to be developed into improved antidotes for nerve agent therapy.
