Discovery of Benzo[<i>cd</i>]indol-2(1<i>H</i>)-ones and Pyrrolo[4,3,2-<i>de</i>]quinolin-2(1<i>H</i>)-ones as Bromodomain and Extra-Terminal Domain (BET) Inhibitors with Selectivity for the First Bromodomain with Potential High Efficiency against Acute Gouty Arthritis
reported inhibitors show selectivity within the BET family. Herein, we identified a series of benzo[cd]indol-2(1H)-ones and pyrrolo[4,3,2-de]quinolin-2(1H)-ones with good selectivity for BET BD1. Through structure-based optimization, highly active and selective compounds are ultimately obtained. The representative compounds are the first reported inhibitors with selectivity more than 100-fold for BRD4(1)
Synthesis, crystal structure, cholinesterase inhibitory activity, evaluation of insecticidal activities, and computational studies of new phosphonic acids
present study, docking results showed that bisphosphonic acids had lower binding energy and higher inhibition compared with tetraphosphonic acids due to the type of their topology and the ability of their hydrogen to interact with the catalytic triad (the main active site of the enzyme). Additionally, the QSAR results demonstrated that the major effecting factors on the insecticidalactivity of the

In this study, a series of 2-[p-fluorophenyl]-6-substituted-9H-purine analogues were designed and synthesized as CHK1 inhibitors, among which compound b22 was the most potent. b22 exhibited nearly no antiproliferative activity toward HT29 cells and displayed a significant antitumor potentiating effect on HT29 cells when treated in combination with gemcitabine (Gem). A time-dependent assay found that

A new, base-free high turnover number (TON) catalyst for hydrogenation of simple and functionalized amides is prepared by reacting [Ru(η3-C3H5)(Ph2P(CH2)2NH2)2]BF4 and BH4− under hydrogen. The hydrogenation proceeds with C–N cleavage to form the corresponding amine and alcohol. The base-free and base-promoted hydrogenations tolerate alcohols, amines, aromatic bromides, chlorides and fluorides, ethers
