Treatment of patients with triple-negative breast cancer (TNBC) is challenging due to the absence of well- defined molecular targets and the heterogeneity of such disease. In our endeavor to develop potent isatin-based anti-proliferative agents, we utiliz
Discovery of N -(4-(3-(2-Aminopyrimidin-4-yl)pyridin-2-yloxy)phenyl)-4-(4-methylthiophen-2-yl)phthalazin-1-amine (AMG 900), A Highly Selective, Orally Bioavailable Inhibitor of Aurora Kinases with Activity against Multidrug-Resistant Cancer Cell Lines

Efforts to improve upon the physical properties and metabolic stability of Aurora kinase inhibitor 14a revealed that potency against multidrug-resistant cell lines was compromised by increased polarity. Despite its high in vitro metabolic intrinsic cleara
Synthesis of 4-substituted chlorophthalazines, dihydrobenzoazepinediones, 2-pyrazolylbenzoic acid, and 2-pyrazolylbenzohydrazide via 3-substituted 3-hydroxyisoindolin-1-ones

Figure Persented: Herein we describe a general three-step synthesis of 4-substituted chlorophthalazines in good overall yields. In the key step, N,N-dimethylaminophthalimide (8a) directs the selective monoaddition of alkyl, aryl, and heteroaryl organometallic reagents to afford 3-substituted 3-hydroxyisoindolinones 9b, 9i-9am. Many of these hydroxyisoindolinones are converted to chlorophthalazines 1b-1v via reaction with hydrazine, followed by chlorination with POCl3. We have also discovered two novel transformations of 3-vinyl- and 3-alkynyl-3-hydroxyisoindolinones. Addition of vinyl organometallic reagents to N,N-dimethylaminophthalimide (8a) provided dihydrobenzoazepinediones 15a-15c via the proposed ring expansion of 3-vinyl-3-hydroxyisoindolinone intermediates. 3-Alkynyl-3-hydroxyisoindolinones react with hydrazine and substituted hydrazines to afford 2-pyrazolyl benzoic acids 16a-16d and 2-pyrazolyl benzohydrazides 17a-17g rather than the expected alkynyl phthalazinones.

We report nineteen 4-aryl- and 4-arylalkyl-1-phthalazinamines (5-8) which we prepared and tested for antithrombotic properties. All compounds were assayed for their antiplatelet activity in the "Born test" with collagen as inducer of the aggregation. N-[4-(1H-1,2,4-triazol-1-yl)butyl]-4-phenyl-1-phthalazin-amine (7c) was the most potent compound, having an IC50 of 8 μM. When 5-HT (Serotonin) was used to start aggregation the N-(furan-2-yl-methyl)-4-phenyl-1-pthtalazinamine (8a) had an IC50 of 2 μM. In vivo potencies were highly significant. N-[5-(1H-1,2,4-triazol-1-yl)pentyl]-4-phenyl-1-phthalazinamine (7d) inhibited thrombus formation by 12% (P 2A receptor, which is most likely the mechanism of the inhibition of aggregation by this compound.
