A major obstacle in the therapeutic development of phosphodiesterase-4 (PDE4) inhibitors is the production of adverse side effects such as nausea and vomiting. Immunohistochemical detection of Fos-like immunoreactivity (FLI) was used to address the neuroanatomical basis for the pharmacological
N-(3,5-Dichloro-1-oxido-4-pyridinyl)-8-methoxy-2-(trifluoromethyl)-5-quinoline carboxamide (SCH 351591) has been identified as a potent (IC(50) = 58 nM) and highly selective type 4 phosphodiesterase (PDE4) inhibitor with oral bioactivity in several animal models of lung inflammation.
Norfloxacin is a quinoline (quinolinecarboxylic acid) that should prove successful in treating infections that currently require hospitalization and intravenous antibiotics. Although a nalidixic acid derivative, it possesses greater antibacterial activity against gram-positive and gram-negative
In a study of conformational requirements for certain dopaminergic agonist molecules, a series of conformationally predictable dopamine congeners related to cis- and trans-octahydrobenzo[f]quinoline was prepared. The complexity and equivocal character of the reduction of variously substituted
A combination of pharmacological and genetic approaches was used to determine the role of type 4 cAMP-specific cyclic nucleotide phosphodiesterase 4 (PDE4) in reversing alpha(2)-adrenoceptor-mediated anesthesia, a behavioral correlate of emesis in non-vomiting species. Among the family-specific PDE
The objective of this work was to assess the role of alpha(2)-adrenoceptors in emesis induced by inhibitors of type 4 phosphodiesterase (PDE4) in ferrets. Pre-treatment with yohimbine, MK-912 or MK-467 (alpha(2)-adrenoceptor antagonists) caused sudden and unexpected vomiting. In contrast, clonidine
Bosutinib (SKI-606) is a 4-anilino-3-quinoline carbonitrile, which acts as a dual inhibitor of Src and ABL kinases. In addition, the BCR-ABL fusion gene product, a constitutively activated tyrosine kinase which is crucial for the development of chronic myeloid leukemia (CML), is highly sensitive to
Single-dose toxicity studies of prulifloxacin, a new antibacterial agent, were conducted in mice, rats and dogs. In addition, a single-dose toxicity study of (+/-)-6-fluoro-1-methyl-4-oxo-7- (1-piperazinyl)-4H-[1,3]thiazeto[3,2-a]quinoline- 3-carboxylic acid (NM394), an active metabolite of
The toxicities of antimalarial drugs vary because of the differences in the chemical structures of these compounds. Quinine, the oldest antimalarial, has been used for 300 years. Of the 200 to 300 compounds synthesised since the first synthetic antimalarial, primaquine in 1926, 15 to 20 are
Quinoline-3-carboxamide (Linomide) is a novel, synthetic immunomodulator acting via immunologic and non-immunologic mechanisms. It has shown efficacy against various malignancies, experimental autoimmune encephalomyelitis, and septic shock in animal models and has been investigated for clinical use
Brequinar (DUP 785, NSC 368390) is a 4-quinoline carboxylic acid derivative with broad spectrum antitumour activity in experimental models that acts as an antimetabolite by specific inhibition of de novo pyrimidine synthesis. We performed a phase I study of brequinar administered as a 10 min
Brequinar sodium (DUP 785, NSC 368390) is a novel quinoline-carboxylic acid derivative that has been selected for clinical evaluation because of its broad spectrum of antitumor activity in animal models and its novel chemical structure. This compound inhibits the mitochondrial enzyme dihydroorotate
Brequinar sodium is a quinoline carboxylic acid derivative that has shown antitumor activity in a number of in vivo murine and human tumor xenograft models. Its mechanism of action is blockade of de novo pyrimidine biosynthesis by inhibition of dihydroorotic acid dehydrogenase. In vitro and in vivo
BACKGROUND
Tasquinimod is an oral quinoline-3-carboxamide derivative for the treatment of metastatic castration-resistant prostate cancer (mCRPC). Tasquinimod has antiangiogenic, immunomodulatory, and antimetastatic properties, but it is also associated with toxicities, including skeletal pain,
