Description: Dabigatran, also known as BIBR 953, is an oral anticoagulant from the class of the direct thrombin inhibitors. It is being studied for various clinical indications and in some cases it offers an alternative to warfarin as the preferred orally administered anticoagulant ("blood thinner") since it does not require blood tests for international normalized ratio (INR) monitoring while offering similar results in terms of efficacy. There is no specific way to reverse the anticoagulant effect of dabigatran in the event of a major bleeding event, unlike warfarin, although a potential dabigatran antidote (pINN: idarucizumab) is undergoing clinical studies. It was developed by the pharmaceutical company Boehringer Ingelheim.

Product Data:

Biological target: Dabigatran etexilate (BIBR 1048) is an orally active prodrug of Dabigatran that has anticoagulant effects and also is used for the prophylaxis of venousthromboembolism and stroke due to atrial fibrillation.
In vitro activity: Apoptosis of liver specimens after IRI was evaluated by TUNEL staining in the IRI + vehicle (Fig. 3A‐a) and IRI + dabigatran groups (Fig. 3A‐b). Dabigatran treatment markedly reduced the number of TUNEL‐positive cells compared with vehicle (84.20 [IQR, 69.00101.57] in IRI + vehicle, 5.15 [IQR, 3.85‐9.67] in IRI + dabigatran, P = 0.004; Fig. 3B). In addition, compared with vehicle, dabigatran treatment attenuated activation of caspase 9, one of the proapoptotic mediators evaluated by Western blot analysis (cleaved‐caspase 9/pro‐caspase 9: 1.04 [IQR, 0.96‐1.09] in IRI + vehicle, 0.69 [IQR, 0.54‐0.86] in IRI + dabigatran, P = 0.01; Fig. 3C), and upregulated generation of bcl‐2, an antiapoptotic gene evaluated by real‐time PCR (bcl‐2/β‐actin: 0.97 [IQR, 0.87‐1.01] in IRI + vehicle, 1.61 [IQR, 1.45‐1.79] in IRI + dabigatran, P = 0.006; Fig. 3D).The number of Ly6G‐positive cells was significantly lower in the IRI + dabigatran group than in the IRI + vehicle group (5.80 [IQR, 5.40‐7.10] in IRI + dabigatran, 38.30 [IQR, 24.6042.55] in IRI + vehicle, P = 0.004; Fig. 3F). Gene expression evaluated by real‐time PCR showed that dabigatran treatment significantly reduced VCAM‐1 compared with vehicle (VCAM‐1/β‐actin: 0.35 [IQR, 0.32‐0.39] in IRI + dabigatran, 1.10 [IQR, 0.561.32] in IRI + vehicle, P = 0.01; Fig. 3G). As shown in Fig. 3H,I, dabigatran treatment markedly reduced generation of inflammatory cytokines such as TNF‐α and IL6 compared with vehicle (TNF‐α/β‐actin: 0.21 [IQR, 0.10‐0.29] in IRI + dabigatran, 0.96 [IQR, 0.441.51] in IRI + vehicle, P = 0.02; IL6/β‐actin: 0.02 [IQR, 0.01‐0.03] in IRI + dabigatran, 0.24 [IQR, 0.18‐1.90] in IRI + vehicle, P = 0.006).

In vivo activity: This study was undertaken to test whether dabigatran etexilate attenuates lung injury in a murine model of interstitial lung disease. Lung injury was induced in female C57BL/6 mice by a single intratracheal instillation of bleomycin. Dabigatran etexilate was given as supplemented chow beginning on day 1 of bleomycin instillation (early treatment, study of antiinflammatory effect) or on day 8 following bleomycin instillation (late treatment, study of antifibrotic effect). Both early treatment and late treatment with dabigatran etexilate attenuated the development of bleomycin-induced pulmonary fibrosis. Dabigatran etexilate significantly reduced thrombin activity and levels of transforming growth factor β1 in BAL fluid, while simultaneously reducing the number of inflammatory cells and protein concentrations. Histologically evident lung inflammation and fibrosis were significantly decreased in dabigatran etexilatetreated mice. Additionally, dabigatran etexilate reduced collagen, connective tissue growth factor, and α-smooth muscle actin expression in mice with bleomycin-induced lung fibrosis, whereas it had no effect on basal levels of these proteins. This data provides preclinical information about the feasibility and efficacy of dabigatran etexilate as a new therapeutic approach for the treatment of interstitial lung disease.
