| Description | Tiotropium Bromide hydrate is an anticholinergic and bronchodilator and a muscarinic receptor antagonist.
Target: mAChR
Tiotropium bromide (Ba 679 BR) is a novel potent and long-lasting muscarinic antagonist that has been developed for the treatment of chronic obstructive airways disease (COPD). Binding studies with [3H]tiotropium bromide in human lung have confirmed that this is a potent muscarinic antagonist with equal affinity for M1-, M2- and M3-receptors and is approximately 10-fold more potent than ipratropium bromide. In vitro tiotropium bromide has a potent inhibitory effect against cholinergic nerve-induced contraction of guinea-pig and human airways, that has a slower onset than atropine or ipratropium bromide. tiotropium bromide dissociates slowly from M3-receptors (on airway smooth muscle) but rapidly from M2 autoreceptors (on cholinergic nerve terminals) [1]. Tiotropium bromide is a quaternary ammonium derivative that binds to muscarinic receptors. However, although tiotropium binds with high affinity to muscarinic receptors of M1-, M2- and M3-subtypes, it dissociates very slowly from M1- and M3-receptors but more rapidly from M2-receptors, thereby giving it a unique kinetic selectivity [2].

Tiotropium bromide inhibits TGF-beta-induced MMP production from lung fibroblasts by interfering with Smad and MAPK pathways in vitro.[Pubmed:20856827]
Int J Chron Obstruct Pulmon Dis. 2010 Sep 7;5:277-86.
BACKGROUND: chronic obstructive pulmonary disease (COPD) is characterized by chronic inflammation and structural alterations (ie, tissue remodeling) throughout the conducting airways, parenchyma, and pulmonary vasculature. Matrix metalloproteinases (MMPs) are extracellular degrading enzymes that play a critical role in inflammatory cell infiltration and tissue remodeling, but the influence of the agents that are used for the treatment of COPD on the production of MMPs is not well understood. PURPOSE: the present study aimed to examine the influence of Tiotropium Bromide hydrate (TBH) on the production of MMPs from lung fibroblasts (LFs) induced by transforming growth factor (TGF)-beta in vitro. METHODS: LFs, at a concentration of 5 x 10(5) cells.mL(-1), were stimulated with TGF-beta in the presence of various concentrations of TBH. MMP-1 and MMP-2 levels in culture supernatants were examined by enzyme-linked immunosorbent assay (ELISA), and MMP messenger ribonucleic acid (mRNA) expression was examined by real-time polymerase chain reaction (RT-PCR). The influence of TBH on TGF-beta signaling pathways was also analyzed by examining Smad activation and signaling protein phosphorylation by ELISA. RESULTS: TBH at more than 15 pg.mL(-1) inhibited the production of MMP-1 and MMP-2, but not tissue inhibitor of matrix metalloproteinase (TIMP)-1 and TIMP-2, from LFs, after TGF-beta stimulation. TBH also suppressed MMP mRNA expression through the inhibition of Smad activation and signaling protein, extracellular-signal-regulated kinase (ERK) 1 and 2, and c-Jun N-terminal kinase (JNK), phosphorylation. CONCLUSION: These results may suggest that TBH suppresses MMP production from LFs, through interference of TGF-beta-mediated signaling pathways and results in favorable modification of the clinical status of COPD.
Suppressive activity of tiotropium bromide on matrix metalloproteinase production from lung fibroblasts in vitro.[Pubmed:19281093]
Int J Chron Obstruct Pulmon Dis. 2008;3(4):781-9.
BACKGROUND: Chronic obstructive pulmonary disease (COPD) is characterized by airway remodeling with an accumulation of inflammatory cells. There is also increasing evidence that metalloproteinases (MMPs) may contribute to the pathogenesis of COPD, but the influence of agents that used for the treatment of COPD is not well understood. OBJECTIVE: We evaluated whether Tiotropium Bromide hydrate (TBH), a M3 muscarinic receptor antagonist, could inhibit MMP production from lung fibroblasts (LFs) in response to tumor necrosis factor (TNF)-alpha stimulation. METHODS: LFs were established from normal lung tissues taken from patients with lung tumors. LFs (5 x 10(5) cells/ml) were stimulated with TNF-alpha in the presence of various concentrations of TBH. After 24 h, culture supernatants were obtained and assayed for the levels of MMPs and tissue inhibitor of metalloproteinases (TIMPs) by ELISA. The influence of TBH on mRNA expression of MMPs and TIMPs in 4h-cultured cells was also examined by real-time RT-PCR. Furthermore, nuclear factor-kappaB (NF-kappaB) and activator protein-1 (AP-1) in LFs treated with TBH for 4h was examined by ELISA. RESULTS: TBH at more than 15 pg/ml inhibited the production of MMP-2 from LFs after TNF-alpha stimulation, whereas TIMP-1 and TIMP-2 production was scarcely affected by TBH through the suppression of both mRNA expression and transcription factor, NF-kappaB, activation in LFs induced by TNF-alpha stimulation. CONCLUSION: These results suggest that the attenuating effect of TBH on MMP-2 production from LFs induced by inflammatory stimulation may be additional beneficial therapeutic effects not directly relating to its bronchodilatory effects.
