- Evaluation of 3-carboxy-4(1H)-quinolones as inhibitors of human protein kinase CK2
-
Due to the emerging role of protein kinase CK2 as a molecule that participates not only in the development of some cancers but also in viral infections and inflammatory failures, small organic inhibitors of CK2, besides application in scientific research, may have therapeutic significance. In this paper, we present a new class of CK2 inhibitors-3-carboxy-4(1H)-quinolones. This class of inhibitors has been selected via receptor-based virtual screening of the Otava compound library. It was revealed that the most active compounds, 5,6,8-trichloro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid (7) (IC 50 = 0.3 μM) and 4-oxo-1,4-dihydrobenzo[h]quinoline-3-carboxylic acid (9) (IC50 = 1 μM), are ATP competitive (Ki values are 0.06 and 0.28 μM, respectively). Evaluation of the inhibitors on seven protein kinases shows considerable selectivity toward CK2. According to theoretical calculations and experimental data, a structural model describing the key features of 3-carboxy-4(1H)-quinolones responsible for tight binding to CK2 active site has been developed.

- Cyanoacrylates. Herbicidial and Photosynthetic Inhibitory Activity
-
Various alkyl 3-ohenylamino-2-cyano- and 2-ethoxycarbonylacrylates and 3-phenylamino-2-cyanoacrylonitriles were synthesized and assayed as inhibitors of the Hill reaction in isolated pea chloroplast suspensions and as pre- and post-emergent herbicides on mustard and barnyard grass.Many of the compounds were potent Hill reaction inhibitors and several showed significant herbicidial activity.
