Synthesis, biological evaluation and 3D-QSAR studies of 1,2,4-triazole-5-substituted carboxylic acid bioisosteres as uric acid transporter 1 (URAT1) inhibitors for the treatment of hyperuricemia associated with gout
relationship (SAR) exploration led to the discovery of a highly potent novel URAT1 inhibitor 1g, which was 225-fold more potent than the parent lesinurad in vitro (IC50 = 0.032 μM for 1g against human URAT1 vs 7.20 μM for lesinurad). Besides, 3D-QSAR pharmacophore models were established based on the activity of the compounds (1a-1s) by AccelrysDiscovery Studio 2.5/HypoGen. The best hypothesis, Hypo
作为我们正在进行的开发新型URAT1抑制剂的研究的一部分,合成了19种基于羧酸生物甾醇的化合物(1a-1s),并测试了其体外URAT1抑制剂的活性(IC50)。通过结构-活性关系(SAR)的探索,发现了一种高效的新型URAT1抑制剂1g,在体外其效价比其亲代lesinurad强225倍(1g对人URAT1的IC50 = 0.032μM,而对于lesinurad的7.20μM )。此外,根据Accelrys Discovery Studio 2.5 / HypoGen的化合物(1a-1s)的活性建立了3D-QSAR药效团模型。最好的假设,Hypo 1,通过三种方法(成本分析,Fisher随机化和留一法)进行了验证。尽管化合物1g是目前正在临床试验中开发的最有效的URAT1抑制剂,
Synthesis of novel Ag(I)-<i>N</i>-heterocyclic carbene complexes soluble in both water and dichloromethane and their antimicrobial studies
Abstract The interaction of the benzimidazolium salt with Ag2O in dichloromethane to prepare novel Ag(I)-N-heterocyclic carbene complexes has been carried out at room temperature for 48 h in the absence of light. The obtained complexes were identified and characterized by 1H and 13C NMR, FT-IR and elemental analysis techniques. In addition, it has been found that some of the complexes are antimicrobially

This invention relates to potent selective agonists of the EP4 subtype
of prostaglandin E2 receptors of formula (I), their use or a formulation thereof
in the treatment of glaucoma and other conditions which are related to elevated
intraocular pressure in the eye of the patient.
A pyrrolidine-mediated Knoevenagel-type reaction for highlystereoselective construction of novel α-halo-1,3-dienylsulfonyl fluorides was achieved in up to 100% Z-selectivity and high yields at room temperature from condensation of the readily available aldehydes and halomethanesulfonyl fluorides. This protocol provided a class of unique α-halo-1,3-dienylsulfonyl fluorides with wide scope and excellent
