- USE OF QUINAZOLINE-BASED TYROSINE KINASE INHIBITORS FOR THE TREATMENT OF CANCERS WITH NRG1 FUSIONS
-
Provided herein are methods of selecting cancer patients for treatment with quinazoline-based tyrosine kinase inhibitors, either alone or in combination with anti- HER2/HER3 antibodies, as well as methods of treating cancer patients so selected. Cancer patients are selected for treatment if their cancer has an NRG1 fusion. Selected patients are then treated with quinazoline-based tyrosine kinase inhibitors alone or in combination with anti -HER2/HER3 antibodies.

- N-Arylation of Carbamates through Photosensitized Nickel Catalysis
-
A highly efficient method of visible light mediated Ni(II)-catalyzed photoredox N-arylation of Cbz-amines/Boc-amines with aryl electrophiles at room temperature is reported. The methodology provides a common access to a wide variety of N-aromatic and N-heteroaromatic carbamate products that find use in the synthesis of several biologically active molecules and provides a distinct advantage over traditional palladium-catalyzed Buchwald reaction.

- Syntheses of [14C] and [2H4]PD0205520, an inhibitor of the tyrosine kinase activity of the epidermal growth factor receptor
-
5-(4-Methyl-piperazin-1-yl)-pent-2-ynoic acid [4-(3-chloro-4-fluoro- phenylamino)-pyrido[3,4-d]pyrimidin-6-yl]-amide, PD0205520, was under investigation as a potential inhibitor of the tyrosine kinase (TK) activity of the epidermal growth factor receptor (EGFR) for cancer treatment. Both radio- and stable-isotope-labeled compounds were required for drug absorption, distribution, metabolism and excretion (ADME) and quantitative mass spectrometry bio-analytical studies. PD0205520 14C-labeled in the pyrimidine ring system was prepared in seven steps in an overall radiochemical yield of 26% from [14C]thiourea. PD0205520 2H-labeled in the piperazine ring was synthesized in four steps in a 32% overall yield. Copyright

- Syntheses and EGFR kinase inhibitory activity of 6-substituted-4-anilino [1,7] and [1,8] naphthyridine-3-carbonitriles
-
The syntheses and EGFR kinase inhibitory activity of a series of 6-substituted-4-anilino [1,7] and [1,8] naphthyridine-3-carbonitriles are described. Both reversible and irreversible binding inhibitors were prepared. These series were compared with each other and with the corresponding 4-anilinoquinoline-3-carbonitriles. Compounds having a 1,7-naphthyridine core structure can retain high potency while those with a 1,8-naphthyridine core are significantly less active. These results are consistent with molecular modeling observations.

- Synthesis of 6-substituted pyrido[3,4-d]pyrimidin-4(3H)-ones via directed lithiation of 2-substituted 5-aminopyridine derivatives
-
Directed lithiation of Boc or pivaloyl derivatives of 2-substituted 5-aminopyridines with BuLi-TMEDA in diethyl ether at -10°C gave 4-lithio derivatives which were quenched with CO2 to give the analogous C-4 carboxylic acids. Hydrolysis of the protecting groups with either TFA or aqueous KOH gave 2-substituted 5-aminopyridine-4-carboxylic acids which were converted to 6-substituted pyrido[3,4-d]pyrimidin-4(3H)-ones by reaction with formamide or, more optimally, formamidine acetate. Boc protected aminopyridines provided the best overall results, with synthesis of these derivatives best achieved by direct reaction of the aminopyridine with di-tert-butyl dicarbonate in the absence of added base.
