pyridine/diarrhea

A series of imidazo[1,2-a]pyrrolo[2,3-c]pyridines has been prepared and evaluated for their anti-BVDV activities in MDBK cells. From the synthesized analogues bearing modifications of the substituents at positions 2, 3, 7 and 8, compounds 10a, b, 16, 24, 25 and 26 exhibited significant anti-BVDV

A novel class of inhibitors of pestiviruses (5-substituted 2-phenyl-5H-imidazo[4,5-c]pyridines) is described. Modification of the substituent in position 5 resulted in analogues with high activity (EC(50)<100nM) and selectivity (SI>1000) against the pestivirus BVDV (bovine viral diarrhea virus).

2,6-Bis(benzimidazol-2-yl)pyridine (BBP/CSFA-0) was identified in a CPE-based screening as a selective inhibitor of the in vitro bovine viral diarrhea virus (BVDV) replication. The EC50-values for the inhibition of BVDV-induced cytopathic (CPE) effect, viral RNA synthesis and the production of

Cryptosporidium parvum is an enteric protozoan parasite that has emerged as a major cause of diarrhea, malnutrition, and gastroenteritis and poses a potential bioterrorism threat. C. parvum synthesizes guanine nucleotides from host adenosine in a streamlined pathway that relies on inosine

A desirable attribute of novel antimicrobial agents for bacterial diarrhea is decreased toxicity toward host intestinal microbiota. In addition, gut dysbiosis is associated with an increased risk of developing intestinal cancer. In this study, the selective growth-inhibitory activities of ten

The pharmacological properties of MO-8282 (1,2,3,4-tetrahydro-2-methyl-9H-dibenzo [3,4: 6,7]cyclohepta [1,2-c]pyridine maleate) as an antidepressant were investigated. At doses 10 times less than those of amitriptyline, MO-8282 showed similar potencies in reducing the duration of immobility during

To determine the mechanisms of K+ loss in viral diarrhea, K+ fluxes (estimated by tracer Rb+ flows) across piglet jejunum in Ussing chambers were determined. Normal jejunum was characterized by an indomethacin-sensitive short-circuit current and a small K+ secretory flow. Rotavirus-infected gut

Based on the discovery of beta-D-2'-deoxy-2'-fluorocytidine as a potent anti-hepatitis C virus (HCV) agent, a series of beta-D- and L-2'-deoxy-2'-fluoroibonucleosides with modifications at 5 and/or 4 positions were synthesized and evaluated for their in vitro activity against HCV and bovine viral

Pyrazine diazohydroxide (NSC-361456) was identified as an active congener of pyridine 2-diazohydroxide with enhanced stability under physiologic conditions. In this phase I study, 35 patients with advanced cancer received 62 courses of PZDH administered intravenously every 3 weeks at doses ranging

The efficacy of 2-Pyridine aldoximide methiodide (PAM) for lethal acute poisoning by fenitrothion (FNT) was investigated in mice and dogs. Sumithion (FNT 51.7%, emulsifiers 12.5% and xylol 35.8%) was used as fenitrothion. 1. FNT at 1500 mg/kg was administered orally to mice. After ten minutes 50

Two 6β- N-heterocyclic naltrexamine derivatives, NAP and NMP, have been identified as peripherally selective mu opioid receptor (MOR) antagonists. To further enhance the peripheral selectivity of both compounds, the 17-amino group and the nitrogen atom of the pyridine ring in both NAP and NMP were

Based on the discovery of (2'R)-d-2'-deoxy-2'-fluorocytidine as a potent anti-hepatitis C virus (HCV) agent, a series of d- and l-2'-deoxy-2'-fluororibonucleosides with modifications at 5- and/or 4-positions were synthesized and evaluated for their in vitro activity against HCV and bovine viral

Ethyl 2-methylimidazo[1,2-a]pyrrolo[2,3-c]pyridin-8-carboxylate (AG110) was identified as a potent inhibitor of pestivirus replication. The 50% effective concentration values for inhibition of bovine viral diarrhea virus (BVDV)-induced cytopathic effect, viral RNA synthesis, and production of

We report on the highly potent and selective antipestivirus activity of 5-[(4-bromophenyl)methyl]-2-phenyl-5H-imidazo[4,5-c]pyridine (BPIP). The 50% effective concentration (EC50) for inhibition of bovine viral diarrhea virus (BVDV)-induced cytopathic effect formation was 0.04 +/- 0.01 microM.
