Compounds are provided that act as potent antagonists of the CCR1 receptor, and which
have been further confirmed in animal testing for inflammation, one of the hallmark
disease states for CCR1. The compounds are generally aryl piperazine derivatives
and are useful in pharmaceutical compositions, methods for the treatment of
CCR1-mediated diseases, and as controls in assays for the identification of
competitive CCR1 antagonists.

thiazolopyrimidine derivatives was designed, synthesized and screened for in‐vitro inhibition of DipeptidylPeptidaseIV (DPP IV). The SAR study indicated the influence of substituted chemical modifications on thiazolopyrimidine scaffold. Compound 9 (IC50 = 0.489 μm) and 10 (IC50 = 0.329 μm) having heterocyclic‐substituted piperazine with acetamide linker resulted as most potent DPP IVinhibitors among all the compounds
Design, synthesis, in vitro and in vivo evaluation of novel pyrrolizine-based compounds with potential activity as cholinesterase inhibitors and anti-Alzheimer's agents
Novel series of pyrrolizine based compounds (4–6 and 9–11) were designed, synthesized and evaluated as potential anti-Alzheimer agents. Most of the tested compounds showed selectivity to hAChE over hBChE and effectively inhibited self–induced amyloid beta aggregation in vitro. Among these derivatives, compound 10 displayed high selectivity towards hAChE (Ki = 1.47 ± 0.63 μM for hAChE and Ki = 40.15 ± 3
Six piperazine derivatives 6a – f containing 1,4-benzodioxan moiety have been synthesized and characterized by 1 H NMR, ESI-MS and elemental analysis. The structure of 6d was further confirmed by single crystal X-ray diffraction. All these novel compounds were screened for their in vivo anti-inflammatory activity employing classical para -xylene-induced mice ear-swelling model. The results revealed
已经合成了六个含有1,4-苯并二恶烷部分的哌嗪衍生物6a – f,并通过1 H NMR,ESI-MS和元素分析对其进行了表征。单晶X射线衍射进一步证实了6d的结构。使用经典的对二甲苯诱导的小鼠耳肿胀模型筛选所有这些新化合物的体内抗炎活性。结果表明,大多数目标化合物均具有显着的抗炎活性,特别是在苯基哌嗪环上具有邻位取代甲氧基的化合物6a表现出最佳的活性。
