- Discovery and Optimization of 2 H-1λ2-Pyridin-2-one Inhibitors of Mutant Isocitrate Dehydrogenase 1 for the Treatment of Cancer
-
Neomorphic mutations in isocitrate dehydrogenase 1 (IDH1) are oncogenic for a number of malignancies, primarily low-grade gliomas and acute myeloid leukemia. We report a medicinal chemistry campaign around a 7,7-dimethyl-7,8-dihydro-2H-1λ2-quinoline-2,5(6H)-dione screening hit against the R132H and R132C mutant forms of isocitrate dehydrogenase (IDH1). Systematic SAR efforts produced a series of potent pyrid-2-one mIDH1 inhibitors, including the atropisomer (+)-119 (NCATS-SM5637, NSC 791985). In an engineered mIDH1-U87-xenograft mouse model, after a single oral dose of 30 mg/kg, 16 h post dose, between 16 and 48 h, (+)-119 showed higher tumoral concentrations that corresponded to lower 2-HG concentrations, when compared with the approved drug AG-120 (ivosidenib).

- A novel approach to bis(1,3-azol-2-yl)acetonitriles and bis(1,3-azol-2-yl)methanes: Via the [3 + 2]-dipolar cycloaddition of imidazole N -oxides and 2-heteroaryl-3,3-dimethylacrylonitriles
-
A new synthetic approach for obtaining previously unknown bis(1,3-azol-2-yl)acetonitriles and bis(1,3-azol-2-yl)methanes has been developed. It is based on 1,3-dipolar cycloaddition between 2-unsubstituted imidazole N-oxides and 2-(1,3-azol-2-yl)-3,3-dimethylacrylonitriles, which are easily available through the condensation of (1,3-azol-2-yl)acetonitriles with acetone. The method allows for the construction of various unsymmetric derivatives based on imidazole, oxazole, thiazole, and 1,3,4-thiadiazole cyclic molecules. Its potential has been demonstrated via the synthesis of 24 diverse derivatives with yields of 29-92%. Bis(1,3-azol-2-yl)acetonitriles can be converted to the corresponding bis(1,3-azol-2-yl)methanes via simple acid hydrolysis followed by subsequent spontaneous decarboxylation at nearly quantitative yields.

- New direct inhibitors of InhA with antimycobacterial activity based on a tetrahydropyran scaffold
-
Tetrahydropyran derivative 1 was discovered in a high-throughput screening campaign to find new inhibitors of mycobacterial InhA. Following initial in-vitro profiling, a structure-activity relationship study was initiated and a focused library of analogs was synthesized and evaluated. This yielded compound 42 with improved antimycobacterial activity and low cytotoxicity. Additionally, the crystal structure of InhA in complex with inhibitor 1 was resolved, to reveal the binding mode and provide hints for further optimization.

- Influence of the structures of α-halo ketones and thioamides on the Hantzsch synthesis of thiazoles and thiazolo[5,4-b]indoles. A new approach to 4-acetyl-2-methyl-4H-thiazolo[5,4-b]indole
-
In reactions with some α-halo ketones (3-bromo-1,1,1-trifluoropropan- 2-one, 1-acetyl-2-bromoindolin-3-one, and α-bromoacetophenone), thioacetamide and a series of thioamides of aromatic and heteroaromatic acids are transformed into 4-hydroxy-Δ2-thiazolines rather than into thiazoles (the expected Hantzsch reaction products). To the contrary, thiazoles are produced in the reactions of the same α-halo ketones with thioamides of phenylacetic, diphenylacetic, 3-indolylacetic, or cyanoacetic acids. The abnormal course of the Hantzsch reaction in the former case results from the fact that 4-hydroxy-Δ2-thiazolines, which are intermediates in the thiazole synthesis, undergo virtually no dehydration under the Hantzsch reaction conditions. The ease of dehydration of hydroxythiazolines under the conditions of the thiazole synthesis and the possibility of the spontaneous thiazole synthesis depend on the nature of the substituent at position 2 and, consequently, on the structure of the starting thioamide. The Me, Ar, and Het substituents impede dehydration, whereas substituents containing the α-methylene (methine) unit at the C(2) atom of the thiazoline moiety substantially facilitate this reaction. The conditions for the dehydration of 4-acetyl-2-methyl-8b-hydroxy-3a,8b-dihydro-4H-thiazolo[5,4-b]indole under basic catalysis were found, and a new procedure was developed for the preparation of thiazoles and 2-R-thiazolo[5,4-b]indoles, whose synthesis presents difficulties or is impossible under standard conditions.
