  Structure-Based Design of Novel Class II c-Met Inhibitors: 2. SAR and Kinase Selectivity Profiles of the Pyrazolone Series

  摘要：

  As part of our effort toward developing an effective therapeutic agent for c-Met-dependent tumors, a pyrazolone-based class II c-Met inhibitor, N-(4-((6,7-dimethoxyquinolin-4-yl)oxy)-3-fluorophenyl)-1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazole-4-carboxamide (1), was identified. Knowledge of the binding mode of this molecule in both c-Met and VEGFR-2 proteins led to a novel strategy for designing more selective analogues of 1. Along with detailed SAR information, we demonstrate that the low kinase selectivity associated with class II c-Met inhibitors can be improved significantly. This work resulted in the discovery of potent c-Met inhibitors with improved selectivity profiles over VEGFR-2 and IGF-1R that could serve as useful tools to probe the relationship between kinase selectivity and in vivo efficacy in tumor xenograft models. Compound 59e (AMG 458) was ultimately advanced into preclinical safety studies.

• Copper/Persulfate-Promoted Oxidative Decarboxylative C−H Acylation of Pyrazolones with α-Oxocarboxylic Acids: Direct Access to 4-Acylpyrazolones under Mild Conditions
  作者：Tanakorn Kittikool、Akkharaphong Thupyai、Khamphee Phomphrai、Sirilata Yotphan

  facile and efficient oxidative C−H acylation of N‐substituted pyrazolones using α‐oxocarboxylic acids as an acyl group source was developed. A combination of Cu(OAc)2 and K2S2O8 enables the reaction to proceed smoothly under air and provides a wide array of 4‐acylpyrazolone products in moderate to excellent yields. The mechanism of this transformation is believed to proceed via a copper‐induced decarboxylation

  使用α-氧代羧酸作为酰基源，开发了一种简便，有效的N-取代吡唑啉酮的氧化CH-H酰化方法。Cu（OAc）2和K 2 S 2 O 8的组合可使反应在空气中顺利进行，并以中等到极好的收率提供各种各样的4-酰基吡唑啉酮产品。据信这种转变的机理是通过铜诱导的脱羧反应形成酰基铜物质而进行的。该方法为将酰基部分直接安装到生物活性吡唑啉酮衍生物中提供了方便且有用的途径，该途径可进一步用于许多应用中。

  Heating of squaric acid (1) with the 1-aryl-3-methyl-5-oxo-2,5-dihydro-1H-pyrazoles 3a - j and the 1,3-disubstituted pyrazolinones 7a - d in the molar ratio of 1:2 in a mixture of n-BuOH/toluene afforded the bis(pyrazolyl)-squaraines 4a - j and 8a - d, respectively. Reaction of an excess of 1 with the pyrazolinone 3j yielded 4j and the 3-hydroxy-4-pyrazolyl-cyclobutene-1,2-dione 6 as a byproduct. In contrast to disubstituted pyrazolinones, the trisubstituted pyrazolinones 9a - e reacted with squaric acid (1) to give the hydroxy-oxopyrazolyl-cyclobutenediones 10a - e.

  Formal regiodivergent C–H alkynylation of 1-aryl-5-pyrazolones has been realized under the catalysis of Rh(III) and Au(I) complexes by using a hypervalent iodine reagent as the alkyne source. Mechanistic studies indicate that the regioselectivity is ascribed to not only the choice of the catalyst but also the nature of the substrate. The substrate scope and functional group compatibility have been
