  Design, Synthesis, and Biological Evaluation of Indole Biphenylcarboxylic Acids as PPARγ Antagonists

  摘要：

  The thiazolidinediones (TZD) typified by rosiglitazone are the only approved therapeutics targeting PPAR gamma for the treatment of type-2 diabetes (T2DM). Unfortunately, despite robust insulin sensitizing properties, they are accompanied by a number of severe side effects including congestive heart failure, edema, weight gain, and osteoporosis. We recently identified PPAR gamma antagonists that bind reversibly with high affinity but do not induce transactivation of the receptor, yet they act as insulin sensitizers in mouse models of diabetes (SR1664).(1) This Letter details our synthetic exploration around this novel series of PPAR gamma antagonists based on an N-biphenylmethylindole scaffold. Structure-activity relationship studies led to the identification of compound 46 as a high affinity PPAR gamma antagonist that exhibits antidiabetic properties following oral administration in diet-induced obese mice.

  A novel series of carbazole carboxamides was discovered as potent RORγt inverse agonists using a scaffold hybridization strategy. Structure-activity relationship exploration on the amide linker, carbazole ring and arylsulfone moiety of the hybrid amide 3a led to identification of potent RORγt inverse agonists. Compound 6c was found to have a good RORγt activity with an IC50 of 58.5 nM in FRET assay

  使用支架杂交策略，发现了一系列新的咔唑羧酰胺作为有效的RORγt反向激动剂。对杂合酰胺3a的酰胺连接基，咔唑环和芳基砜部分进行构效关系研究，从而鉴定出了有效的RORγt反向激动剂。在FRET分析中发现化合物6c具有良好的RORγt活性，IC 50为58.5 nM，在小鼠Th17细胞分化试验中具有合理的抑制活性（在0.3μM时抑制率为58.8％）。讨论了咔唑羧酰胺在RORγt配体结合域中的结合方式。

  The invention provides molecular entities that bind with high affinity to PPARG (PPARγ), and inhibit kinase-mediated (e.g., cdk5-mediated) phosphorylation of PPARG, but do not exert an agonistic effect on PPARG. Compounds of the invention can be used for treatment of conditions in patients wherein PPARG plays a role, such as diabetes, insulin resistance, impaired glucose tolerance, pre-diabetes, hyperglycemia, hyperinsulinemia, obesity, or inflammation. Side effects such as significant weight gain, edema, impairment of bone growth or formation, or cardiac hypertrophy, or any combination thereof, can be avoided in the mammal receiving the compound. Methods of preparation of the compounds, bioassay methods for evaluating compounds of the invention as non-agonistic PPARG binding compounds, and pharmaceutical compositions are also provided.
