Alkyne–azide cycloaddition derivatives of DHZ (1) were synthesized and screened for cytotoxic potential in which the derivatives, 3, 6, 7, 8, 9 and 15 displayed most potent with IC50 value ranging from 1.8–3.0 μM.
Design, combinatorial synthesis and biological evaluations of novel 3-amino-1′-((1-aryl-1 H -1,2,3-triazol-5-yl)methyl)-2′-oxospiro[benzo[ a ] pyrano[2,3- c ]phenazine-1,3′-indoline]-2-carbonitrile antitumor hybrid molecules
activity against the A549 cancer cell line with IC50 value of 5.4 μM. All compounds had low or no effect against L02 and HUVEC non-cancer cell lines. Compound 36 was further confirmed to mainly locate mitochondria in A549 cancer cells via laser-scanning confocal microscopy. Moreover, compound 36 was proved to increase ROS production and induce cellcyclearrest in Sphase. Western blot analysis illustrated

proven to be an effective metalloradical catalyst for intermolecularamination of C(sp2)–H bonds of aldehydes with fluoroaryl azides. The [Co(P1)]-catalyzed process can employ aldehydes as the limiting reagents and operate under neutral and nonoxidative conditions, generating nitrogen gas as the only byproduct. The metalloradical aldehydic C–H amination is suitable for different combinations of aldehydes
D 2h对称酰胺卟啉 3,5-Di t Bu-IbuPhyrin [Co( P1 )]的 Co( II ) 配合物已被证明是一种有效的金属基催化剂,用于 C(sp 2 )–H 键的分子间胺化醛与氟芳基叠氮化物。[Co( P1 )]-催化过程可以使用醛作为限制试剂并在中性和非氧化条件下运行,产生氮气作为唯一的副产品。金属基醛 C-H 胺化适用于醛和氟芳基叠氮化物的不同组合,产生相应的N-氟芳基酰胺的产率非常好。一系列机理研究支持 Co( II ) 催化的分子间 C-H 胺化的逐步自由基机制。

aliphatic esters with ethanol and calcium nitride afforded the corresponding primaryamides in a transformation that was compatible with a variety of functional groups and maintained the integrity of a stereocenter α to carbonyl. This methodology was applied to α-amino esters and N-BOC dipeptide esters and also to the synthesis of rufinamide, an antiepileptic drug.
