Abstract
Muscarine acetylcholine receptors (mAChRs) regulate a variety of central and peripheral physiological functions and emerge as important therapeutic targets for a number of diseases including chronic obstructive pulmonary disease (COPD). Inspired by two active natural products, we designed and synthesized a series of 2-(2,2-diarylethyl)-cyclamine derivatives for screening M3 mAChR antagonists. On this skeleton, the structural units including N heterocycle, aryl groups and its substituents on aryl were examined and resulted in a clear structure-activity relationships on the M3 mAChR. In general, these 2-(2,2-diarylethyl)-cyclamine derivatives exhibited good to excellent M3 antagonistic potency and receptor selectivity. The most active 5b-C1 had an IC50 value of 3 nM and the most of compound 6 displayed inactivity against histamine H1 receptor closely related to M3. In in vitro and in vivo evaluations of tracheo-relaxation function, some compounds even showed comparable activity to tiotropium bromide, a known blockbuster drug for COPD. Such excellent properties made these novel compounds potential candidates for COPD drug development.

Abstract
Molecular topology has been used to select new lead bronchodilator compounds. The main advantage of this method, as compared to others frequently used, is that it does not require a previous explicit knowledge of the mechanism of action (MOA) of the compounds analyzed. A large database (12,000 chemicals) has been examined in this study to find less than 5% compounds with bronchodilator activity. After removing those compounds already described as bronchodilators, we present here the results for 20 among these compounds, some of them showing other pharmacological activities. Some of the compounds selected in this study showed higher relaxation and higher potency than theophylline, which is the reference drug used in the bronchodilator assay performed. For instance, tetrahydro-papaveroline showed significantly higher values than theophylline (93.9% versus 77.0% and pD2=7.30 versus pD2=4.69, respectively). Other compounds, although eliciting small or no relaxation at 0.1mM, produced larger relaxation at higher concentrations (1mM). In conclusion, the molecular topology based approach used in this work has demonstrated to be effective in the search of new bronchodilators.

Abstract
Protein kinase C appears to be involved in the regulation of airway contractility. Phorbol 12,13-diacetate (PDA; 0.01-10 microM), a protein kinase C activator, produced a transient relaxation followed by a sustained contraction of human isolated bronchus. Different protein kinase C inhibitors (calphostin C, staurosporine and 1-(5-isoquinolinesulfonyl)-2-methylpiperazine) (H-7), nifedipine (NIF; 1 microM) or incubation with Ca(2+)-free medium, inhibited the spasmogenic response to phorbol, while ouabain (10 microM) suppressed only the initial relaxation. These results indicate that the initial relaxation, in response to PDA, is related to the activation of Na(+)/K(+)-ATPase, while the ensuing contraction depends on extracellular Ca(2+) entry.Incubation with PDA (1-5 microM) depressed the maximal relaxation to theophylline and caffeine obtained at 37 degrees C but augmented the spasmogenic responses to methylxanthines (10 mM) obtained in cooled preparations. These effects do not result apparently from increased extracellular entry of Ca(2+), but instead, from facilitation of the release of Ca(2+) from intracellular stores.

Abstract
1. The contractile response to nitric oxide (NO) in ral ileal myenteric plexus-longitudinal muscle strips was pharmacologically analysed. 2. NO (10(-7) M) induced only contraction while 10(-6) M NO induced contraction followed by relaxation. Methylene blue (up to 10(-4) M) did not affect the NO-induced contractions but significantly reduced the relaxation evoked by 10(-6) M NO. Administration of 8-bromo-cyclic GMP (10(-6)-10(-4) M) only induced relaxation. 3. Sodium nitroprusside (SNP; 10(-7)-10(-5) M) induced concentration-dependent contractions per se; the contractile response to NO, administered within 10 min after SNP, was concentration-dependently reduced. The guanosine 3':5'-cyclic monophosphate (cyclic GMP) content of the tissues was not increased during contractions with 10(-8) M NO and 10(-6) M SNP; it was increased by a factor of 2 during contraction with 10(-7) M NO, and by a factor of 12 during relaxation with 3 x 10(-6) M NO. 4. The NO-induced contractions were not affected by ryanodine (3 x 10(-5) M) but were concentration-dependently reduced by nifedipine (10(-8)-10(-7) M) and apamin (3 x 10(-9)-3 x 10(-8) M). 5. These results suggest that cyclic GMP is not involved in the NO-induced contraction in the rat small intestine. The NO-induced contraction is related to extracellular Ca2+ influx through L-type Ca2+ channels, that might be activated in response to the closure of Ca(2+)-dependent K+ channels.

Abstract
1. H-7, a protein kinase C inhibitor, fully inhibited the spontaneous and stimulated (KCl 20 mM or histamine 0.5 mM) tone of trachea from normal and sensitized guinea pig. 2. H-7 depressed the concentration-contraction curves to KCl, histamine or 5-hydroxytryptamine in epithelium-denuded, indomethacin-treated, trachea from normal and sensitized guinea pigs while responses to CaCl2 (in Ca2+ -free, K+ -depolarized tissues) and acetylcholine were not affected. 3. H-7 (100 microM did not depress Ca2+ (20 microM-induced contraction of Triton X-100 skinned trachea. 4. These results suggest the involvement of PKC in the maintenance of spontaneous tone and spasmogenic responses of guinea pig trachea.

Abstract
We have studied the effects of phorbol 12,13-diacetate (PDA) and its influence on a variety of spasmogenic responses in trachea isolated from normal and sensitized guinea-pigs. Tracheal preparations were denuded of epithelium, treated with indomethacin (2.8 microM), and cooled to 20 degrees C. In these experimental conditions, tracheal strips contracted to PDA (0.1 nM-1 microM). Contractions to PDA (1 microM) were greater in sensitized tissues. In normal trachea, contractions to PDA (0.1 microM) were depressed by H-7, 1-(5-isoquinolinyl-sulphonyl)-2-methylpiperazine, (50 microM), amiloride (10 microM), verapamil (10 microM) and Ca(2+)-free exposure. Similar effects were obtained in sensitized trachea except that PDA-induced contraction was resistant to verapamil and Ca(2+)-free exposure. Cooling (20 degrees C) of normal trachea substantially depressed the response to CaCl2 (in K(+)-depolarized tissues), KCl, histamine and 5-hydroxytryptamine without affecting the spasm induced by acetylcholine. This inhibitory effect of cooling was not observed in sensitized trachea. PDA (0.1 microM) did not affect spasmogenic responses at 37 degrees C but counteracted the inhibitory effect of cooling in normal trachea. PDA had no effect on sensitized tissues. PDA (0.1-1 microM) did not alter Ca(2+)-induced contraction of skinned normal and sensitized trachea. These results support the hypothesis that intracellularly stored Ca2+ plays an important role in the activation of sensitized tracheal muscle.

Abstract
1. The involvement of protein kinase C (PKC) in constriction of small bronchioles has never been investigated. In this study we have examined the effects of the specific PKC inhibitors Ro31-8220 and Ro31-7549 and the non-specific inhibitor H7 on carbachol-, 5-hydroxytryptamine (5-HT)- and 4 beta-phorbol dibutyrate (4 beta-PDBu)-induced contractions in large and small bronchioles. 2. The study was performed on isolated bronchioles of the rat with internal diameters of 574 microns +/- 11 (small, n = 128), and 1475 microns +/- 32 (large, n = 93), using a Mulvaney-Halpen small vessel myograph. 3. In these preparations 4 beta-PDBu had no effect if added on its own. However, after precontracting with 30 mM K+, 0.5 microM 4 beta-PDBu caused a contractile response of 110.4 +/- 7.0% TK (TK = maximum response to 75 mM K+ in small and 69.3 +/- 6.5% TK in large bronchioles. Ro31-8220, Ro31-7549 and H7 all showed concentration-dependent inhibition of this response. 4. In small bronchioles 10 microM Ro31-8220 shifted both the carbachol and 5-HT concentration-response curves to the right, and reduced the maximum response. In contrast, 10 microM Ro31-8220 had no significant effect on the EC50 to carbachol of larger bronchioles, although the maximum response was reduced, and had no significant effect on the 5-HT concentration-response curve. 200 microM H7 shifted the carbachol concentration--response curve to the right as well as reducing the maximal response in both small and large bronchioles. 5 Large bronchioles exhibited a greater rate of decay of carbachol-induced contraction than did small bronchioles. Pretreatment with Ro31-8220 accelerated the rate of decay.6 Pretreatment with 10 JM Ro3l-8220 caused a small reduction in the response to 75 mM K+ in both small and large bronchioles (small: to 87.8 +/- 3.0% TK; large: to 94.1 +/- 0.8% TK). H7 at 200 JM caused a much larger reduction in both preparations (small: to 75.1 +/- 3.0% TK); large: to 82.7 +/- 0.6% TK).7 Small bronchioles were more sensitive than larger bronchioles to agonists and phorbol ester. The protein kinase inhibitor Ro31-8220 could reduce agonist-induced constriction in small and large bronchioles,as well as reducing or abolishing phorbol ester-induced contractions. Small bronchioles were more sensitive than large bronchioles to Ro31-8220. These results suggest that there is a significant PKC involvement in constriction of bronchioles to carbachol and 5-HT, and that the proportion of the contractile response that can be attributed to PKC is greater in smaller than larger bronchioles.
