Protein tyrosine phosphatase 1B is a negative regulator in the insulin and leptin signaling pathways, and has emerged as an attractive target for the treatment of type 2 diabetes and obesity. However, the essential pharmacophore of charged phosphotyrosine or its mimetic confer low selectivity and poor cell permeability. Starting from our previously reported aryl diketoacid-based PTP1B inhibitors, a drug-like scaffold of 4-quinolone-3-carboxylic acid was introduced for the first time as a novel surrogate of phosphotyrosine. An optimal combination of hydrophobic groups installed at C-6, N-1 and C-3 positions of the quinolone motif afforded potent PTP1B inhibitors with low micromolar IC 50 values. These 4-quinolone-3-carboxylate based PTP1B inhibitors displayed a 2-10 fold selectivity over a panel of PTP's. Furthermore, the bidentate inhibitors of 4-quinolone-3-carboxylic acids conjugated with aryl diketoacid or salicylic acid were cell permeable and enhanced insulin signaling in CHO/hIR cells. The kinetic studies and molecular modeling suggest that the 4-quinolone-3-carboxylates act as competitive inhibitors by binding to the PTP1B active site in the WPD loop closed conformation. Taken together, our study shows that the 4-quinolone-3-carboxylic acid derivatives exhibit improved pharmacological properties over previously described PTB1B inhibitors and warrant further preclinical studies.
Design, synthesis and insecticidal activity of novel anthranilic diamides with benzyl sulfide scaffold
Chen, Yin-Bo,Li, Ji-Ling,Shao, Xu-Sheng,Xu, Xiao-Yong,Li, Zhong
, p. 673 - 676 (2013/07/26)
A series of novel anthranilic diamides with benzyl sulfide scaffold were synthesized, in which N-pyridylpyrazole moiety generally regarded as key pharmacophore was abandoned. The target compounds were characterized by 1H NMR, 13C NMR, 19F NMR and HRMS. The preliminary bioassays indicated that half of the title compounds were endowed with good insecticidal activities against armyworm (Mythimna sepatara) at the concentration of 500 mg/L. Exhilaratingly, the synthesized compound 3a was also active against Tetranychus cinnabarinus at 100 mg/L. The difference in activities between the target compounds was influenced by the substituents, which provided some hints for further investigation on structure modifications.

Human immunodeficiency virus type 1 (HIV-1) integrase is a crucial target for antiretroviral drugs, and several keto - enol acid class (often referred to as diketo acid class) inhibitors have clinically exhibited-marked antiretroviral activity. Here, we show the synthesis and the detailed structure - activity relationship of the quinolone carboxylic acids as a novel monoketo acid class of integrase inhibitors. 6-(3-Chloro-2-fluorobenzyl)-1-((2S)-1-hydroxy-3,3- dimethylbutan-2-yl)-7-methoxy-4-oxo-1,4-dihydroquinoline-3-carboxylic acid 51, which showed an IC50 of 5.8 nMin the strand transfer assay and an ED50 of 0.6 nMin the antiviral assay, and 6-(3-chloro-2-fluorobenzyl) -1-((2S)-1-hydroxy-3-methylbutan-2-yl)-7-methoxy-4-oxo-1,4-dihydroquinoline-3- carboxylic acid 49, which had an IC50 of 7.2 nMand an ED50 of 0.9 nM, were the most potent compounds in this class. The monoketo acid 49 was much more potent at inhibiting integrasecatalyzed strand transfer processes than 3′-processing reactions, as is the case with the keto - enol acids. Elvitegravir 49 was chosen as a candidate for further studies and is currently in phase 3 clinical trials.
