Dibutyryl-cGMP sodium (Bt2cGMP sodium) is a cell-permeable cGMP analog. Dibutyryl-cGMP sodium preferentially activates cGMP-dependent protein kinase (PKG). Dibutyryl-cGMP sodium inhibits [3H]-arachidonic acid release in human platelets stimulated by gamma
Solabegron (GW-427,353), is a selective agonist of β3 adrenergic receptors. In addition, Solabegron has been shown to produce visceral analgesia by releasing somatostatin from fat cells.
Dafphedyn, [D-Ala2, (F5) Phe4]-dynorphin 1-13-NH2 (DAFPHEDYN) is an effective analog of strong endorphin 1-13 and produces diuretic and deep analgesia when administered intravenously in rats.
