description Ferid Murad Overview
Ferid Murad (1936–2023) was an American pharmacologist whose research focused on cell signaling and drug mechanisms. He shared the 1998 Nobel Prize in Physiology or Medicine with Robert Furchgott and Louis Ignarro for discoveries concerning nitric oxide as a signaling molecule in the cardiovascular system. Murad showed that nitric oxide is released from nitrovasodilator compounds such as nitroglycerin, activating the enzyme guanylate cyclase to raise cyclic GMP levels in smooth muscle cells. This cascade relaxes vascular smooth muscle and lowers blood pressure.
help Ferid Murad FAQ
What did Ferid Murad discover about nitroglycerin and blood vessels?
Ferid Murad discovered that nitric oxide is a crucial signaling molecule that causes blood vessels to widen. He figured out that drugs like nitroglycerin work by releasing nitric oxide to relax vascular smooth muscle.
When was Ferid Murad awarded the Nobel Prize?
He was awarded the 1998 Nobel Prize in Physiology or Medicine. His work revealed that a gas could act as a signaling molecule in the cardiovascular system, a completely novel concept at the time.
With whom did Ferid Murad share the 1998 Nobel Prize?
He shared the 1998 Nobel Prize in Physiology or Medicine with Robert Furchgott and Louis Ignarro. Furchgott identified an elusive endothelium-derived relaxing factor, which Ignarro and Murad ultimately proved was nitric oxide.
What impact did Ferid Murad's research have on medicine?
His discovery that nitric oxide regulates blood pressure and vascular tone directly led to the development of numerous cardiovascular treatments. The mechanisms he uncovered are also famously utilized in erectile dysfunction medications like Viagra, which relies on nitric oxide pathways.
