Intramolecular diamination reactions are described which yield cyclic ureas as direct products of an oxidative alkene transformation in the presence of palladium acetate and iodosobenzenediacetate as terminal oxidant. The reaction is truly catalytic in metal catalyst and represents the proof of principle for this elusive type of alkene oxidation.

The invention is directed to substituted salicylamide derivatives. Specifically, the invention is directed to compounds according to FormµLa (I): wherein R, R1,P, X, Y, and Z are as defined herein; or a pharmaceutically acceptable salt thereof. The compounds of the invention are inhibitors of CD73 and can be usefµL in the treatment of cancer, pre-cancerous syndromes and diseases associated with CD73 inhibition, such as AIDS, the treatment of HIV, autoimmune diseases, infections, atherosclerosis, and ischemia–reperfusion injury. Accordingly, the invention is further directed to pharmaceutical compositions comprising a compound of the invention. The invention is still further directed to methods of inhibiting CD73 activity and treatment of disorders associated therewith using a compound of the invention or a pharmaceutical composition comprising a compound of the invention.
important therapeutic targets such as the isocitrate dehydrogenase 2 (IDH2). A series of macrocyclic derivatives was designed based on the marketed IDH2 inhibitor AG-221 by using the conformational restriction strategy. The resulted compounds showed moderate to good inhibitory potential against different IDH2-mutant enzymes. Amongst, compound C6 exhibited better IDH2R140Q inhibitory potency than AG-221,

A proximity-driven covalent bond with intrinsically less reactive warheads has been made possible by using a metal-chelating anchor for directed targeted covalent modification of Cys165 within the BoNT/A protease.

synthesis, and evaluation of a new class of HIV-1proteaseinhibitors containing diverse flexible macrocyclic P1′-P2′ tethers are reported. Inhibitor 5a with a pyrrolidinone-derived macrocycle exhibited favorable enzyme inhibitory and antiviral activity (Ki = 13.2 nM, IC50 = 22 nM). Further incorporation of heteroatoms in the macrocyclic skeleton provided macrocyclic inhibitors 5m and 5o. These compounds
报道了设计,合成和评估一类新型的HIV-1蛋白酶抑制剂,其包含多种柔性大环P1'-P2'系链。具有吡咯烷酮衍生的大环的抑制剂5a表现出良好的酶抑制和抗病毒活性(K i = 13.2 nM,IC 50 = 22 nM)。在大环骨架中进一步掺入杂原子可提供大环抑制剂5m和5o。这些化合物显示出出色的HIV-1蛋白酶抑制性(分别为K i = 62 pM和14 pM)和抗病毒活性(IC 50分别 为5.3 nM和2.0 nM)。抑制剂5o 它还对DRV耐药的HIV-1变异株具有很高的效力。
