This disclosure provides compounds having drug and bio-affecting properties, their pharmaceutical compositions and method of use. In particular, the disclosure is concerned with diketo piperazine and piperadine derivatives that possess unique antiviral activity. More particularly, the present disclosure relates to compounds useful for the treatment of HIV and AIDS.
The present invention relates to certain 6-phenyl-pyridin-2-ylamine derivatives that exhibit activity as nitric oxide synthase (NOS) inhibitors, to pharmaceutical compositions containing them and to their use in the treatment and prevention of central nervous system disorders.
on the ADME/T and oral glucose tolerance test (OGTT) in ICR mice. Compound 22 showed the improved bioavailability and blood glucose-lowering effect in vivo compared to its free base 21h probably attributed to its improved solubility and permeability. The preliminary toxicity studies on compound 22 exhibited that the result of mini-Ames was negative and the preliminary acutetoxicity LD50 in mice was
通过成环策略发现了一系列源自先前命中的20i的黄嘌呤化合物,它们在末端侧链上进行了修饰。对疏水侧链中带有刚性杂环的化合物的系统优化导致了新的先导化合物HBK001(21h),其具有改进的DPP-IV抑制作用和体外适度的GPR119激动活性。为了进一步研究PK和PD谱图,我们继续以克为单位合成21h及其盐酸盐(22),并通过ADME / T和口服糖耐量试验(OGTT)对ICR小鼠进行了评估。与其游离碱21h相比,化合物22在体内显示出改善的生物利用度和降低血糖的作用,这可能归因于其溶解度和渗透性的改善。对化合物22的初步毒性研究表明,mini-Ames的结果为阴性,小鼠的初步急性毒性LD50高于1.5 g / kg,而对hERG通道的抑制作用中等,IC50为4.9μM,可能是由于其高亲脂性。这些发现对于将来针对更有效,更安全的靶向DPP-IV和GPR119的双配体治疗糖尿病的药物设计将是有用的。
