Lificiguat (YC-1) is an nitric oxide (NO)-independent activator of soluble guanylyl cyclase(sGC) and an inhibitor of Hypoxia-inducible factor-1alpha (HIF-1alpha).

Nicardipine hydrochloride (YC-93 Hydrochloride) is the hydrochloride salt form of nicardipine, a synthetic derivative of nitrophenyl-pyridine and potent calcium channel blocker, Nicardipine (Nifedipine Family) blocks calcium ions from certain cell walls and inhibits contraction of coronary and peripheral arteries, resulting in lowered oxygen requirements for heart muscle and decreased arterial contraction and spasm. It is used clinically as a cerebral and coronary vasodilator.

GEM-5, a gemcitabine-based conjugate incorporating a HIF-1α inhibitor (YC-1) (IC 50 =30 nM), notably suppresses HIF-1α expression while enhancing tumor suppressor p53 expression. It induces apoptosis in A2780 cells and curbs tumor growth [1].
