Wang, Ruifeng;Chen, Yixuan;Zhao, Xiangxin;Yu, Sijia;Yang, Bowen;Wu, Tianxiao;Guo, Jing;Hao, Chenzhou;Zhao, Dongmei;Cheng, Maosheng research published \u300a Design, synthesis and biological evaluation of novel 7H-pyrrolo[2,3-d]pyrimidine derivatives as potential FAK inhibitors and anticancer agents\u300b, the research content is summarized as follows. A series of 7H-pyrrolo[2,3-d]pyrimidine derivatives possessing a dimethylphosphine oxide moiety I<\/strong> (20a<\/strong>–i<\/strong>, R5<\/sup>, R6<\/sup>, R7<\/sup> = H, R3<\/sup> = acylamino, sulfamoyl, phosphonomethyl, carbamoyl, amino; 25a<\/strong>–h<\/strong>, R3<\/sup> = 4-piperidinylaminocarbonyl, R5<\/sup> = H, halo, alkoxy, CF3<\/sub>, R6<\/sup> = H, Me, F, R7<\/sup> = H, F) and II<\/strong> (22a<\/strong>–g<\/strong>, R4<\/sup> = Me. CHF2<\/sub>CH2<\/sub>, MeOCH2<\/sub>CH2<\/sub>, tetrahydropyranyl, piperidinyl, CH2<\/sub>CONMe2<\/sub>) were designed, synthesized and evaluated as novel Focal adhesion kinase (FAK) inhibitors. Most compounds potently suppressed the enzymic activities of FAK, with IC50<\/sub> values in the 10-8<\/sup>-10-9<\/sup> M range, and potently inhibited the proliferation of breast (MDA-MB-231) and lung (A549) cancer cell lines. The representative compound 25b<\/strong> (R5<\/sup> = OMe, R6<\/sup> = R7<\/sup> = H) exhibited potent enzyme inhibition (IC50<\/sub> = 5.4 nM) and good selectivity when tested on a panel of 26 kinases. Compound 25b<\/strong> exhibited antiproliferative activity against A549 cells (IC50<\/sub> = 3.2 \u03bcM) and relatively less cytotoxicity to a normal human cell line HK2. Compound 25b<\/strong> also induced apoptosis and suppressed the migration of A549 cells in a concentration-dependent manner. Further profiling of compound 25b<\/strong> revealed it had good metabolic stability in mouse, rat and human liver microsomes in vitro and showed weak inhibitory activity against various subtypes of human cytochrome P 450. The docking study of compound 25b<\/strong> was performed to elucidate its possible binding modes and to provide a structural basis for further structure-guided design of FAK inhibitors.<\/p>\n

HPLC of Formula: 2075-46-9<\/a>, 4-Nitro-1H-pyrazole, also known as 4-Nitropyrazole, is a useful research compound. Its molecular formula is C3H3N3O2 and its molecular weight is 113.08 g\/mol. The purity is usually 95%.<\/p>\n

4-Nitropyrazole, is a building block for the synthesis of various pharmaceutical compounds, including inhibitors, and therapeutic agents. It can be used for the synthesis of highly selective, brain-penetrant aminopyrazole LRRK2 Inhibitor, as a potentially viable treatment for Parkinson’s disease., 2075-46-9.<\/p>\n
