A series of 2-anilino-1,6-dihydro-6-oxo-5-pyrimidinecarboxylic acids with various substituents was synthesized and evaluated in the rat passive cutaneous anaphylaxis test for antiallergic activity. High activity by intraperitoneal and oral administrations was observed for the 3-trifluoromethyl and 2-alkoxyanilino derivatives (64, 79, 81, 82 and 85). Structure-activity relationships are discussed.
The present invention is directed to arginase inhibitor compounds of formula IA or formula IB:
or a pharmaceutically acceptable salt thereof, compositions containing these compounds, and methods of their use for the treatment and diagnosis of conditions characterized by upregulation of arginase, abnormally high arginase activity, or by abnormally low nitric oxide synthase activity.
picolinamides and extraction behaviour has been rationalized by highlighting the relationship between intramolecularhydrogenbonding and rotational isomerism. To this aim aromatic pyridine-2,6-dicarboxamides 1a–1c with N-substitution and their analogues 3a and 3b containing intramolecularhydrogen bonds were designed and synthesized. The results from the liquid–liquid extraction towards some representative

The present invention provides macrocyclic compounds useful as therapeutic agents. More particularly, these compounds are useful as anti-infective, anti-proliferative, anti-inflammatory, and prokinetic agents.
The present invention relates to an aromatic polyimide which has excellent heat resistance and excellent thermal dimensional stability, and which realizes low hygroscopic property, and an aromatic polyamic acid as a precursor for the aromatic polyimide. Provided are an aromatic polyamic acid including a structural unit represented by the following general formula (1), and an aromatic polyimide obtained by imidating the aromatic polyamic acid. The aromatic polyamic acid or the aromatic polyimide can be a copolymerization-type aromatic polyamic acid or aromatic polyimide having another structural unit:
