Discovery of new small molecule inhibitors targeting isocitrate dehydrogenase 1 (IDH1) with blood-brain barrier penetration

Isocitrate dehydrogenase 1 (IDH1), which catalyzes the conversion of isocitrate to α-ketoglutarate, is one of key enzymes in the tricarboxylic acid cycle (TCA). Hotspot mutation at Arg132 in IDH1 that alters the function of IDH1 by further converting the α-ketoglutarate(α-KG) to 2-hydroxyglutarate (2-HG) have been identified in a variety of cancers. Because the IDH1 mutations occur in a significant portion of gliomas and glioblastomas, it is important that IDH1 inhibitors have to be brain penetrant to treat IDH1-mutant brain tumors. Here we report the efforts to design and synthesize a novel serial of mutant IDH1 inhibitors with improved activity and the blood-brain barrier (BBB) penetration. We show that compound 5 exhibits good brain exposure and potent 2-HG inhibition in a HT1080-derived mouse xenograft model, which makes it a potential preclinical candidate to treat IDH1-mutant brain tumors.

2-AMINOPYRIMIDINE DERIVATIVE, PREPARATION METHOD AND USE THEREOF

The disclosure provides an aminopyrimidine derivative for preventing and treating diseases related to IDH mutation, a preparation method and use thereof. Specifically, the disclosure provides a compound of Formula I, a stereoisomer, racemate thereof, or pharmaceutically acceptable salt thereof. The compound of the general Formula I has isocitrate dehydrogenase 1 (IDH1) inhibitory activity and can treat cancer induced by IDH1 mutation.

Access to Chiral Hydropyrimidines through Palladium-Catalyzed Asymmetric Allylic C?H Amination

A palladium-catalyzed asymmetric intramolecular allylic C?H amination controlled by a chiral phosphoramidite ligand was established for the preparation of various substituted chiral hydropyrimidinones, the precursors of hydropyrimidines, in high yields with high enantioselectivities. In particular, dienyl sodium N-sulfonyl amides bearing an arylethene-1-sulfonyl group underwent a sequential allylic C?H amination and intramolecular Diels–Alder (IMDA) reaction to produce chiral fused tricyclic tetrahydropyrimidinone frameworks in high yields and with high levels of stereoselectivity. Significantly, this method was used as the key step in an asymmetric synthesis of letermovir.

Palladium-Catalyzed Aerobic Intramolecular Aminoacetoxylation of Alkenes Enabled by Catalytic Nitrate

A mild aerobic intramolecular aminoacetoxylation method for the synthesis of pyrrolidine and indoline derivatives was achieved using molecular oxygen as the oxidant. A catalytic NOx species acts as an electron transfer mediator to access a high-valent palladium intermediate as the presumed active oxidant.

Synthesis of indolines, indoles, and benzopyrrolizidinones from simple aryl azides

A simple approach to prepare indolines and benzopyrrolizidinones from ortho-azidoallylbenzenes via a tandem radical addition/cyclization is described. The use of triethylborane to initiate and sustain the process provides the best results. Indolines are easily converted into the corresponding indoles by oxidation with manganese dioxide.

Synthesis of substituted 1-benzazepin-2-ones via ring-closing olefin metathesis

The 1-benzazepin-2-one ring system is an important structural feature of marketed drugs, clinical candidates, and other bioactive molecules. We have developed a new benzazepinone synthesis that employs ring-closing olefin metathesis as a key step. This route provides efficient access to substituted benzazepinones that are difficult to synthesize via existing procedures.
