In some cases, the catalyzed mechanism may include additional steps.In a article, 848821-76-1, molcular formula is C21H15F12NO, introducing its new discovery. HPLC of Formula: C21H15F12NO

The present study was undertaken to illustrate the anti-inflammatory activity of seahorse (Hippocampus trimaculatus) extract in carrageenaninduced rat paw oedema model. Molecular docking study was executed with COX-2 and heme oxygenase inhibitor complexes to illustrate the interactions exhibited by seahorse extract metabolite with the target protein. Favourable interactions of seahorse extract metabolite with the active site residues of the COX-2 and heme oxygenase could be correlated with the potency and the compound is proved to be an anti-inflammatory agent as well as an antidote. In vitro anti-inflammatory activity by Human Red Blood Cell (HRBC) membrane stabilisation method was evaluated. Structure Activity Relationship (SAR) of the Cpd1-6 with various functional groups was also evaluated. Cpd6 with ketone, amine and four -CH3 found with best activity with a maximum percentage inhibition (Mean±SEM) 71.72±2.84 and IC50 17.89 mug/mL while Cpd3 with only -CH3 group showed a least activity of 33.24±4.41, IC50 94.38 mug/mL.

The effects of new and potent NOS inhibitors, S-methyl-L-thiocitrulline (S-Me-TC),3-bromo 7-nitro indazole (3-Br-7-NI), and 1-(2- trifluoromethylphenyl)imidazole (TRIM), were examined on the pilocarpine- induced seizures in mice. 3-Br-7-NI and TRIM decreased the frequency of status epilepticus and mortality, while TRIM, in addition, significantly reduced the incidence of seizures. The latencies to onsets of seizures, status epilepticus, and mortality were significantly prolonged by all three NOS inhibitors, while duration of seizures was reduced by 3-Br-7-NI and TRIM. These data suggest an excitatory effect of NO in the neuronal structure involved in the pilocarpine-induced seizures.

The N-methyl-D-aspartnte (NMDA) receptor-nitric oxide (NO) pathway has been linked to opiate withdrawal. Pretreatments with four inhibitors of NO synthase, 7-nitro indazole, 3-bromo-7-nitro indazole, S-methyl-L-thiocitrulline and aminoguanidine, which exhibit different isoform selectivity in vitro, were evaluated for their ability to attenuate signs of naloxone-precipitated morphine withdrawal. In separate experiments, effects of NO synthase inhibitors on blood pressure were measured in naive and morphine-dependent rats. 7-Nitro indazole, 3-bromo-7-nitro indazole and S-methyl-L-thiocitrulline, which are specific inhibitors of the constitutive isoforms, produced dose-dependent reductions of several signs of withdrawal. Blood pressure was unaffected by the indazoles, whereas S-methyl-L-thiocitrulline produced a strong vasoconstrictor response. Aminoguanidine, which selectively inhibits inducible NO synthase, reduced fewer signs of opioid withdrawal, had a lower relative potency and exhibited no vasopressor activity. These data suggest that constitutive isoforms, but not the inducible isoform of NO synthase, have a primary role in NO-mediated processes that modulate the opioid withdrawal syndrome in the rat.

This review includes the non-patent literature up to October 2004 that deals with selective neuronal nitric oxide synthase inhibitors (highest potency is for the neuronal isozyme). Some non-selective inhibitors or selective inducible nitric oxide synthase inhibitors are mentioned if they are related to compounds that are discussed; structures of these compounds generally are not given. In vitro inhibition constants are given either as IC50 values or as Ki values. An IC50 value, the inhibitor concentration that produces 50% inhibition in the presence of a constant concentration of substrate, is obtained by extrapolation of several rate data points to 50% inhibition. Ki values are derived from several types of plots that relate the concentration of inhibitor with enzyme velocity in the presence of a variety of substrate concentrations [1]. The Ki value can be estimated from the IC50 value [2]. Although the two inhibition constants are related, they are not the same; generally, the reported Ki values tend to be lower than the IC50 values. If specifics are desired about how the data were collected, then the reader will have to look in the literature cited. No attempt was made to be exhaustive in citing all references related to specific inhibitors; rather, examples of literature references are given for each inhibitor described.

Taking into account the potency of 4- and 7-nitro and haloindazoles as nNOS inhibitors previously reported in the literature by our team, a multidisciplinary study, described in this article, has recently been carried out to elucidate their binding mode in the enzyme active site. Firstly, nitrogenous fastening points on the indazole building block have been investigated referring to molecular modeling hypotheses and thanks to the in vitro biological evaluation of N1- and N2-methyl and ethyl-4-substituted indazoles on nNOS. Secondly, we attempted to confirm the importance of the substitution in position 4 or 7 by a hydrogen bond acceptor group thanks to the synthesis and the in vitro biological evaluation of a new analogous 4-substituted derivative, the 4-cyanoindazole. Finally, by opposition to previous hypotheses describing NH function in position 1 of the indazole as a key fastening point, the present work speaks in favour of a crucial role of nitrogen in position 2.

The aim of the present study was to evaluate the role of nitric oxide (NO) of sensory neural origin in neurogenic inflammatory response in the trigeminovascular system. Antidromic vasodilatation and plasma extravasation in response to electrical stimulation (15 V, 5 Hz, 0.5 ms, 100 impulses) of the trigeminal ganglion were investigated in the dura mater and nasal mucosa/upper eyelid by laser Doppler flowmetry and [125I]-labelled bovine serum albumin, respectively. Electrical stimulation of the trigeminal ganglion of rats elicited a reproducible ipsilateral enhancement of both meningeal and nasal mucosal blood flow. Nomega-nitro-l-arginine (l-NNA; 4, 8, and 16 mg/kg, i.v.), a nonselective inhibitor of nitric oxide synthase (NOS), inhibited antidromic vasodilatation both in the dura mater (15.86±2.05%, 22.82±2.51%, and 36.28±4.37%) and nasal mucosa (35.46±8.57%, 58.72±9.2%, and 89.99±8.94%) in a dose-dependent manner. Specific inhibitors of neuronal NOS, 7-nitroindazole (7-NI; 20 mg/kg, i.v.) and 3-bromo-7-nitroindazole (3Br-7NI; 10 mg/kg, i.v.) were administered to assess the possible role of NO released from the trigeminal sensory fibres. The meningeal vasodilatation was inhibited by both 3Br-7NI and 7-NI (63.36±7.7% and 49±6.5%, respectively). The nasal hyperaemic response was also reduced by 3Br-7NI (78.26±8.7%). Plasma extravasation in the dura mater and upper eyelid evoked by electrical stimulation of the trigeminal ganglion (25 V, 5 Hz, 0,5 ms, 5 min), expressed as extravasation ratios (ERs) of the stimulated vs. nonstimulated sides, was 1.80±0.8 and 4.63±1.24, respectively. This neurogenic oedema formation was not inhibited by neither l-NNA nor 3Br-7NI. It is concluded that neural nitrergic mechanisms are involved in the meningeal vasodilatation evoked by electrical stimulation of the trigeminal ganglion.

Clobetasol Propionate Is a Heme-Mediated Selective Inhibitor of Human Cytochrome P450 3A5

The human cytochrome P450 (CYP) enzymes CYP3A4 and CYP3A5 metabolize most drugs and have high similarities in their structure and substrate preference. Whereas CYP3A4 is predominantly expressed in the liver, CYP3A5 is upregulated in cancer, contributing to drug resistance. Selective inhibitors of CYP3A5 are, therefore, critical to validating it as a therapeutic target. Here we report clobetasol propionate (clobetasol) as a potent and selective CYP3A5 inhibitor identified by high-Throughput screening using enzymatic and cell-based assays. Molecular dynamics simulations suggest a close proximity of clobetasol to the heme in CYP3A5 but not in CYP3A4. UV-visible spectroscopy and electron paramagnetic resonance analyses confirmed the formation of an inhibitory type I heme-clobetasol complex in CYP3A5 but not in CYP3A4, thus explaining the CYP3A5 selectivity of clobetasol. Our results provide a structural basis for selective CYP3A5 inhibition, along with mechanistic insights, and highlight clobetasol as an important chemical tool for target validation.

Capsaicin-evoked release of immunoreactive calcitonin gene-related peptide from the spinal cord is mediated by nitric oxide but not by cyclic GMP

Recent data support a role for nitric oxide (NO) in pain processing at the level of the spinal cord, possibly via regulation of neuropeptide release. The goal of this study was to determine whether capsaicin, which selectively activates primary afferent neurons and evokes neuropeptide release, acts in an NO-dependent manner. Our results indicate that capsaicin (1 muM)-evoked release of immunoreactive calcitonin gene-related peptide (iCGRP) is significantly reduced in the presence of the NO synthase inhibitor, L-NAME (10-400 nM; F3,45 = 68.38; P < 0.001) and, the selective nNOS inhibitor, 3-bromo-7-nitroindazole (170-680 nM; F5,48 = 56.2; P < 0.01). D-NAME (200 nM) had no effect on capsaicin-evoked iCGRP release. Hemoglobin (an extracellular scavenger of NO; 3 mg/ml) significantly reduced the effect of capsaicin on the release of iCGRP (F1,8 = 9.12; P < 0.05). The NOS substrate, L-arginine, effectively reversed the inhibitory effect of 3-bromo-7-nitroindazole on capsaicin-evoked iCGRP release. To determine whether the NO-mediated release was NMDA-driven, we superfused spinal cord slices with competitive and non-competitive NMDA antagonists in the presence and absence of capsaicin. MK-801 (0.1-10 muM; F4,33 = 8.49; P < 0.0001) and AP-5 (0.01-10 muM; F4,38 = 3.34; P < 0.05) reduced capsaicin-evoked iCGRP release. CNQX, an AMPA/kainate antagonist (10 nM-10 muM), significantly decreased capsaicin-evoked release of iCGRP (F6,42 = 8.76; P < 0.01) in a dose-dependent fashion. Additionally, our results demonstrate that while capsaicin-evoked release is significantly reduced in the presence of LY-83583 (10 muM; F2,18 = 3.46; P < 0.01; a cyclic GMP lowering agent), there is no effect of ODQ (a potent and selective inhibitor of guanylate cyclase). Moreover, the application of a cell permeable analog of cyclic GMP (8-bromo-cGMP; 0.01-1000 muM) is without effect on both basal and evoked iCGRP release. Finally, we observed no colocalization of immunoreactive neuronal NOS (nNOS) with CGRP in the dorsal horn. In summary, these data indicate that capsaicin evokes the release of iCGRP, in part, via the production of NO which enters the extracellular space prior to having an effect. Moreover, iCGRP and nNOS are produced in distinct populations of neurons within the dorsal horn. We conclude that capsaicin-evoked release involves the activation of the NMDA receptor but is also modified by the activation of AMPA or kainate receptors. Finally, these data suggest that while capsaicin-evoked iCGRP release is modified by NO, this release does not require the activation of guanylate cyclase and subsequent production of cyclic GMP.
