Novel pyrazolopyridine-4-yl pyridazinone derivatives serve as phosphodiesterase inhibitors and are useful compounds for use in pharmaceutical products.
Specifically, the compounds of the present invention are pyrazolopyridine-4-yl pyridazinone derivatives represented by the following general formula (1):
(Example: 6-(2-ethyl-7-methoxy-pyrazolo[1,5-a]pyridine-4-yl)-5-methyl-4, 5-dihydro-3(2H)-pyridazinone).

enhanced mouse liver microsome stability. The structure–activity relationship for EphB3 inhibition of both heterocyclicseries was similar. Kinase inhibitory activity was also demonstrated for representative analogs in cell culture. An analog (32, LDN-211904) was also profiled for inhibitory activity against a panel of 288 kinases and found to be quite selective for tyrosine kinases. Overall, these studies
吡唑并[1,5- a ]吡啶的 2-氯苯胺衍生物的构效关系研究表明,通过保留 2-氯苯胺并向 5吡唑并[1,5- a ]吡啶的-位。此外,用咪唑并[1,2- a ]吡啶替代吡唑并[1,5- a ]吡啶具有良好的耐受性,并导致小鼠肝微粒体稳定性增强。EphB3 抑制两种杂环系列的构效关系相似。细胞培养中的代表性类似物也证明了激酶抑制活性。一个模拟 ( 32, LDN-211904) 还分析了对一组 288 种激酶的抑制活性,发现对酪氨酸激酶具有很高的选择性。总体而言,这些研究为检查 EphB3 受体的体外、细胞和潜在的体内激酶依赖性功能提供了有用的分子探针。

Herein we report a practical protocol for the visible-light-induced regiodivergent radical hydropyridylation of unactivated alkenes using pyridiniumsalts. This approach provides a unified synthetic platform to control the regioselectivity of the synthesis of linear or branched C4-alkylated pyridines. A remarkable selectivity switch from the anti-Markovnikov to the Markovnikov product can be achieved
