  Novel, Highly Potent Aldose Reductase Inhibitors:  Cyano(2-oxo-2,3-dihydroindol-3-yl)acetic Acid Derivatives

  摘要：

  Cyano(2-oxo-2,3-dihydroindol-3-yl)acetic acid derivatives were synthesized and tested as a novel class of aldose reductase (ALR2) inhibitors. Each compound was evaluated as a diastereomeric mixture, due to tautomeric equilibria in solution. The parent compound 39 exhibited a good inhibitory activity with an IC50 value of 0.85 muM, similar to that of the well-known ARI sorbinil (IC50 0.50 muM). The concurrent introduction of a halogen and a lipophilic group in the 5- and in the 1-positions, respectively, of the indole nucleus of 39, gave compound 55, cyano[5-fluoro-1-(4-methylbenzyl)-2-oxo-2,3-dihydroindol-3-yl] acetic acid, which displayed the highest activity (IC50 0.075 muM, very close to that of tolrestat IC50 0.046 muM), with a good selectivity toward ALR2 compared with aldehyde reductase (ALR1) (16.4-fold), and no appreciable inhibitory properties against sorbitol dehydrogenase (SD), or glutathione reductase (GR). The isopropyl ester 59, a prodrug of 55, was found to be almost as effective as tolrestat in preventing cataract development in severely galactosemic rats when administered as an eye drop solution. Docking simulation of 55 into a three-dimensional model of human ALR2 made it possible to formulate the hypothesis that the 2-hydroxy tautomer was the active species binding into the catalytic site of the enzyme. This was fully consistent with the structure-activity relationships within this series of cyanooxoindolylacetic acid derivatives.

  A common cause of resistance to kanamycin (KAN) in tuberculosis is overexpression of the enhanced intracellular survival (Eis) protein. Eis is an acetyltransferase that multiacetylates KAN and other aminoglycosides, rendering them unable to bind the bacterial ribosome. By high throughput screening, a series of substituted 1,2,4-triazino-[5,6b]indole-3-thioether molecules were identified as effective Eis inhibitors. Herein, we purchased 17 and synthesized 22 new compounds, evaluated their potency, and characterized their steady-state kinetics. Four inhibitors were found not only to inhibit Eis in vitro, but also to act as adjuvants of KAN and partially restore KAN sensitivity in a Mycobacterium tuberculosis KAN-resistant strain in which Eis is upregulated. A crystal structure of Eis in complex with a potent inhibitor and CoA shows that the inhibitors bind in the aminoglycoside binding site snugly inserted into a hydrophobic cavity. These inhibitors will undergo preclinical development as novel KAN adjuvant therapies to treat KAN-resistant tuberculosis.

  Breast cancer is a serious threat to the health and lives of women. Two novel series of N′-(2-oxoindolin-3-ylidene)-6-methylimidazo[2,1-b]thiazole-5-carbohydrazides and 1-(aryl)-3-(6-methylimidazo[2,1-b]thiazol-5-yl)ureas were designed, synthesized and investigated for their anticancer efficacy against the MCF-7 breast cell line. Three compounds of the first series showed potent activity toward MCF-7 with IC50 in the range 8.38–11.67 µM, respectively, as compared to Sorafenib (IC50 = 7.55 µM). N′-(1-butyl-2-oxoindolin-3-ylidene)-6-methylimidazo[2,1-b]thiazole-5-carbohydrazide inhibited VEGFR-2 with IC50 = 0.33 µM when compared with Sorafenib (IC50 = 0.09 µM). Furthermore, this compound was introduced to PCR assessment, where it increased Bax, caspase 8, caspase 9 and cytochrome C levels by 4.337-, 2.727-, 4.947- and 2.420-fold, respectively, while it decreased levels of Bcl-2, as the anti-apoptotic gene, by 0.359-fold when compared to the untreated control MCF-7. This compound was also arrested in the G2/M phase by 27.07%, compared with 11.31% for the control MCF-7. Furthermore, it induced early and late apoptosis in MCF-7. In addition, a molecular docking study in the VEGFR-2 active site was performed to assess the binding profile for the most active compounds. Moreover, ADME parameters of the targeted compounds were also evaluated.
