Avenciguat: a novel soluble guanylate cyclase activator that affects multiple cell types to inhibit IFN-1 signalling and fibrosis.

ABSTRACT:

Objectives

The soluble guanylate cyclase (sGC) stimulator riociguat is approved for the treatment of pulmonary arterial hypertension and may have antifibrotic effects. However, in fibrotic tissues, oxidative stress and hypoxia can render sGC insensitive to sGC stimulators. sGC activators overcome this limitation. Here, we characterize the novel sGC activator, avenciguat, in preclinical models of SSc.

Methods

Human microvascular endothelial cells-dermal (HMVEC-d) cultured in hypoxic conditions and activated human platelet-rich plasma were incubated with varying doses of avenciguat, and the levels of TGF-β2 and human CXC chemokine family ligand 4 (CXCL4) were measured, respectively. Treatment with avenciguat was analysed in mice with bleomycin-induced dermal and pulmonary fibr
