Stimulation of Cl- secretion by chlorzoxazone

We previously demonstrated that 1-ethyl-2-benzimidazolone (1-EBIO) directly activates basolateral membrane calcium-activated K+ channels (K(Ca)), thereby stimulating Cl- secretion across several epithelia. In our pursuit to identify potent modulators of Cl- secretion that may be useful to overcome the Cl-secretory defect in cystic fibrosis (CF), we have identified chlorzoxazone [5-chloro-2(3H)-benzoxazolone], a clinically used centrally acting muscle relaxant, as a stimulator of Cl- secretion in several epithelial cell types, including T84, Calu-3, and human bronchial epithelium. The Cl- secretory response induced by chlorzoxazone was blocked by charybdotoxin (CTX), a known blocker of K(Ca). In nystatin-permeabilized monolayers, chlorzoxazone stimulated a basolateral membrane I(K), which was inhibited by CTX and also stimulated an apical /(Cl) that was inhibited by glibenclamide, indicating that the G(Cl) responsible for this /(Cl) may be cystic fibrosis transmembrane conductance regulator (CFTR). In membrane vesicles prepared from T84 cells, chlorzoxazone stimulated 86Rb+ uptake in a CTX-sensitive manner. In excised, inside-out patches, chlorzoxazone activated an inwardly-rectifying K+ channel, which was inhibited by CTX. 6- Hydroxychlorzoxazone, the major metabolite of chlorzoxazone, did not activate K(Ca), whereas zoxazolamine (2-amino-5-chlorzoxazole) showed a similar response profile as chlorzoxazone. In normal human nasal epithelium, chlorzoxazone elicited hyperpolarization of the potential difference that was similar in magnitude to isoproterenol. However, in the nasal epithelium of CF patients with the DeltaF508 mutation of CFTR, there was no detectable Cl- secretory response to chlorzoxazone. These studies demonstrate that chlorzoxazone stimulates transepithelial Cl- secretion in normal airway epitheliumun vitro and in vivo, and suggest that stimulation requires functional CFTR in the epithelia.

Synthesis of 3,4-diaminobenzoyl derivatives as factor Xa inhibitors

Abstract The coagulation factor Xa (FXa) plays a central role in the blood coagulation cascade. Recent studies have shown that FXa is a particularly attractive target for the development of oral antithrombotic agents. In view of the excellent pharmaceutical properties of 1,2-phenylenediamine-based FXa inhibitors and the reported structureeactivity relationship (SAR) analysis of FXa inhibitors, we designed and synthesized a series of 3,4-diaminobenzoyl-based FXa inhibitors. Intensive SAR studies on this new series led to the discovery of 3,4-dimethoxyl substituted compound 7b. 7b is a highly potent, selective, direct FXa inhibitor with excellent in vivo antithrombotic activity.

Inhibition of Magnolol and Honokiol on Cytochrome P450 Enzymes in Rat and Human Liver Microsomes

Objective: The purpose of this work is to evaluate the in vitro inhibitory effect of magnolol (MN) and honokiol (HN) on rat/human cytochrome P450 (CYP) enzymes (1A2/1A2, 2D/2D6, 3A/3A4, 2E1/2E1, and 2C/2C9). Methods: Rat liver microsomes (RLM) and human liver microsomes (HLM) were used as the enzyme sources. After the probe substrate of each CYP isoforms was co-incubated individually with MN or HN in RLM or HLM, the metabolite production of each probe substrate in RLM and HLM incubation medium was determined and used to evaluate the activity of corresponding CYP isoforms. Results: MN inhibited rat CYP1A2 and human CYP3A4 with the IC50 values of 10.0 and 56.2 mumol/L, respectively. HN inhibited rat CYP1A2 and CYP2E1, human CYP1A2 and CYP3A4 with the IC50 values of 12.1, 12.6, 17.8, and 43.9 mumol/L, respectively. Conclusion: HN is a moderate or weak inhibitor of human CYP1A2. Both MN and HN are weak or non inhibitors of the other tested human CYP isoforms. The results suggest that no significant metabolic interaction seems likely to occur when the substrate drugs of CYP isoforms tested in the present work are co-administered with MN and HN.

Anti-oligomerization sheet molecules: Design, synthesis and evaluation of inhibitory activities against alpha-synuclein aggregation

Aggregation of alpha-synuclein (alpha-Syn) play a key role in the development of Parkinson Disease (PD). One of the effective approaches is to stabilize the native, monomeric protein with suitable molecule ligands. We have designed and synthesized a series of sheet-like conjugated compounds which possess different skeletons and various heteroatoms in the two blocks located at both ends of linker, which have good pi-electron delocalization and high ability of hydrogen-bond formation. They have shown anti-aggregation activities in vitro towards alpha-Syn with IC50 down to 1.09 muM. The molecule is found binding in parallel to the NACore within NAC domain of alpha-Syn, interfering aggregation of NAC region within different alpha-Syn monomer, and further inhibiting or slowing down the formation of alpha-Syn oligomer nuclei at lag phase. The potential inhibitor obtained by our strategy is considered to be highly efficient to inhibit alpha-Syn aggregation.

Preliminary characterization of a murine model for 1-bromopropane neurotoxicity: Role of cytochrome P450

Neurotoxicity of 1-bromopropane (1-BP) has been reported in both human cases and animal studies. To date, neurotoxicity of 1-BP has been induced in rats but not in mice due to the lethal hepatotoxicity of 1-BP. Oxidization by cytochromes P450 and conjugation with glutathione (GSH) are two critical metabolism pathways of 1-BP and play important roles in toxicity of 1-BP. The aim of the present study was to establish a murine model of 1-BP neurotoxicity, by reducing the hepatotoxicity of 1-BP with 1-aminobenzotriazole (1-ABT); a commonly used nonspecific P450s inhibitor. The results showed that subcutaneous or intraperitoneal injection of 1-ABT at 50?mg/kg body weight BID (100?mg/kg BW/day) for 3?days, inhibited about 92?96% of hepatic microsomal CYP2E1 activity, but only inhibited about 62?64% of CYP2E1 activity in brain microsomes. Mice treated with 1-ABT survived even after exposure to 1200?ppm 1-BP for 4 weeks and histopathological studies showed that treatment with 1-ABT protected mice from 1-BP-induced hepatic necrosis, hepatocyte degeneration, and hemorrhage. After 4-week exposure to 1-BP, the brain weight of 1-ABT(+)/1200?ppm 1-BP group was decreased significantly. In 1-ABT-treated groups, expression of hippocampal Ran protein and cerebral cortical GRP78 was dose-dependently increased by exposure to 1-BP. We conclude that the control of hepatic P450 activity allows the observation of effects of 1-BP on the murine brain at a higher concentration by reduction of hepatotoxicity. The study suggests that further experiments with liver-specific control of P450 activity using gene technology might provide better murine models for 1-bromopropane-induced neurotoxicity.
