Guanylate cyclase agonists
WebOrally administered small molecule agonists of soluble guanylate cyclase (sGC) induced increased numbers of osteoclasts, multifocal bone resorption, increased porosity, and new bone formation in the appendicular and axial skeleton of Sprague-Dawley rats. WebPatients will eventually become refractory to both guanylate cyclase-C agonists and chloride channel activators. This can be overcome by cycling patients through the available prescription medications. Satish SC Rao, MD, PhD, is a professor of medicine at the Medical College of Georgia at Augusta University.

Guanylate cyclase is found in the retina (RETGC) and modulates visual phototransduction in rods and cones. It is part of the calcium negative feedback system that is activated in response to the hyperpolarization of the photoreceptors by light. This causes less intracellular calcium, which stimulates guanylate cyclase-activating proteins (GCAPs). Studies have shown that cGMP synthesis in cones is about 5-10 times higher than it is in rods, which may play an important rol… WebFeb 1, 2024 · Upon binding by GC-C agonists, the intrinsic guanylate cyclase activity of GC-C rapidly elevates the intracellular concentration of the second messenger cyclic guanosine-3′,5′-monophosphate (cGMP) via enzymatic conversion of cytoplasmic guanosine triphosphate (GTP) to cGMP [ 7., 8., 9.].
