Conformationally constrained ortho- Anilino diaryl ureas: Discovery of 1-(2-(1′-Neopentylspiro[indoline-3,4′-piperidine]-1-yl)phenyl) -3-(4-(trifluoromethoxy)phenyl)urea, a potent, selective, and bioavailable P2Y1 antagonist

Preclinical antithrombotic efficacy and bleeding models have demonstrated that P2Y1 antagonists are efficacious as antiplatelet agents and may offer a safety advantage over P2Y12 antagonists in terms of reduced bleeding liabilities. In this article, we describe the structural modification of the tert-butyl phenoxy portion of lead compound 1 and the subsequent discovery of a novel series of conformationally constrained ortho-anilino diaryl ureas. In particular, spiropiperidine indoline-substituted diaryl ureas are described as potent, orally bioavailable small-molecule P2Y1 antagonists with improved activity in functional assays and improved oral bioavailability in rats. Homology modeling and rat PK/PD studies on benchmark compound 3l will also be presented. Compound 3l was our first P2Y1 antagonist to demonstrate a robust oral antithrombotic effect with mild bleeding liability in the rat thrombosis and hemostasis models.

Practical synthesis of quinoxalinones via palladium-catalyzed intramolecular N-arylations

A practical and highly efficient route to the synthesis of pharmaceutically interesting quinoxalinone scaffolds is reported. The key step involves an intramolecular palladium-catalyzed N-arylation under microwave irradiation. The developed methodology tolerates a variety of bromoanilides to afford a diverse collection of bicyclic and polycyclic quinoxalinones in high yield.

Urea antagonists of P2Y1 receptor useful in the treatment of thrombotic conditions

The present invention provides novel ureas containing N-aryl or N-heteroaryl substituted heterocycles and analogues thereof, which are selective inhibitors of the human P2Y1 receptor. The invention also provides for various pharmaceutical compositions of the same and methods for treating diseases responsive to modulation of P2Y1 receptor activity.

Synthesis of tri- and tetracyclic condensed quinoxalin-2-ones fused across the C-3 - N-4 bond

We have studied the preparation of some fused quinoxalinones by Stevens rearrangement of a spiro-quinoxaline-derived ammonium ylide or by treatment of N-(2,4-dinitrophenyl)-and N-(2-nitrophenyl)imino acids with different reducing agents. We have reinvestigated and clarified some related processes found in the literature starting from imino acids derivatives. Additional reactions of the fused quinoxalinones, as well as the useful dehydrogenation/decarboxylation of some easily available 1-arylindoline-2-carboxylic acids to the corresponding 1-arylindoles, are also reported.

Synthesis of quinoxaline derivatives from substituted acetanilides through intramolecular quaternization reactions

The cyclization of 2-dialkylamino-2′-halogeno- and 2-chloro-2′-(dialkylamino)acetanilides to quinoxaline derivatives has been studied in detail. These reactions proceed, respectively, through intramolecular aromatic nucleophilic or aliphatic nucleophilic

Synthesis and aldose reductase inhibitory activity of N-1,N-4-disubstituted 3,4-dihydro-2(1H)-quinoxalinone derivatives

Synthetic routes have been developed for the preparation of 4-acylated, 4-benzenesulfonylated, and 4-methylated 3,4-dihydro-2(1H)-quinoxalinone-1-acetic acids. One example of the corresponding propionic acid has also been made. These compounds have been evaluated for their ability to inhibit bovine lens aldose reductase in vitro. Some members from this series also show weak activity in vivo, inhibiting sorbitol formation in sciatic nerves of streptozotocin-diabetic rats.
